Overcurrent Charging Protection for Wearable Devices Batteries

The overcurrent charging protection function in the protection circuit of wearable devices battery is due to the automatic jump of the step when the test equipment reaches constant voltage or the overvoltage protection of the battery protection circuit.

Improper use can affect the performance of lithium polymer batteries, and even bring security risks. For example, overvoltage charging may cause the battery to explode, and a short circuit between positive and negative electrodes may cause a fire.

For this reason, lithium polymer batteries are generally equipped with special protection circuits in their applications. The battery-specific protection chip (usually called protection °C) cuts off the circuit when it detects misuse of the battery, thus protecting the battery.

The charging and discharging misuse of the battery includes charging or discharging to a normal voltage, using an excessive current for charging and discharging, and even short circuit directly between positive and negative electrodes.

Lithium polymer battery protection circuits widely used in wearable devices,  usually designed with battery charging overvoltage protection, low voltage discharge protection, short circuit protection, and overcurrent protection, but for a long time, overcurrent protection only considers overcurrent discharging, not include protection against overcurrent charging behavior.

In this view, Grepow shaped battery engineer analyzes the overcurrent charging protection function and discusses the possible misjudgment of the laboratory. The test method of the feasible overcurrent charging protection function is given below.

Wearable devices battery overcurrent charging protection

If lithium polymer battery charging current is too large, it will have a large impact on the electrode material structure, result from serious polarization of the battery, and may even cause thermal runaway. Charging with large rate will also affect battery life. In addition, larger current requires a higher current carrying capacity of the product circuit, which is not conducive to the miniaturization of electronic products.

In the past, there was little protection against overcurrent charging designed for lithium polymer batteries of the wearable device, relative to other abnormal charge and discharge conditions. The battery charging behavior is usually easier to be controlled than the discharge behavior, and the overcurrent charging protection function is more expensive to implement than other battery protection functions, and it is necessary to collect the reverse current.

With the development of application fields, the possibility of lithium polymer battery packs being subjected to excessive charging current is gradually increasing. The emergence of various technologies such as wireless charging, fast charging, and high-rate batteries has also increased the probability that lithium polymer batteries will withstand excessive charging currents. Currently, most electronics companies have required battery pack suppliers to have this capability in their protection circuits. Grepow batteries are widely used in all types of wearable devices, all with overcurrent charging protection, in line with national safety requirements.

For the protection of excessive charging current, the most suitable method is to add the over-current charging protection function to the original battery protection IC. The smart battery series lithium polymer battery protection IC produced by Grepow battery company is a typical representative.

2.Verification of overcurrent charging protection

Usually, the wearable device manufacturer will verify the purchased battery pack, and the battery manufacturer will also verify the function of the protection board. When performing product certification or quality supervision and random inspection, the laboratory also needs to verify the functions of the battery pack. For overcurrent charging protection, the inspector needs to have the right technology to verify.

(1) Standard verification requirement

In the lithium polymer battery and battery pack safety requirements for wearable device products, the basic methods and requirements for testing the overcurrent charging protection function are: the charging current is 1. 5 times overcurrent charging protection current, charging voltage is charging upper limit voltage, the state of the test is constant current charging, repeating 500 tests, it is required that the battery pack’s overcurrent protection circuit should respond with each test.

Lithium polymer batteries for common wearable devices have an internal resistance of several tens of milliohms, and there is also impedance on the battery protection board. When the charging limit voltage is set to the battery, the maximum voltage difference between the charging voltage and the battery cell may not guarantee enough test current for the loop. Using the simplified Ohm’s law model we can calculate as follows:

Ucell + I/（Rcell + Rpcm）≤Uup （1）

In formula (1): Ucell refers to the open circuit voltage of the battery, Rcell and  Rpcm are the approximate equivalent resistance of the battery and protection circuit, respectively, UUP is the upper limit voltage of charging, “I” is the current on the loop, then:

1≤ ( Uup – Ucell )/(Rcell +Rpcm) （2）

When the open circuit voltage of the battery is too high, or the upper limit of the set charging voltage is too low, or the resistance of the battery is too large, the loop current I may not reach the value of the overcurrent charging protection function of the trigger protection board. Therefore, the battery must be discharged to empty before the experiment.

(2) Use a large capacity battery

According to formula (2), if the other conditions are the same, only increase the load capacity of the battery (ie, replace the large capacity battery, discharge to empty before the test, that is, reduce the Rcell), will increase the allowed current in the loop. If you use a large capacity battery to connect the battery protection circuit, set the voltage of the DC power to the upper battery charging voltage (such as 4.2 v) to ensure that the over-voltage charging protection is not triggered; set the charging current to 1. 5 times overcurrent charging protection current. If the circuit is cut off after the output, it can be confirmed that the overcurrent charging protection function of the protection circuit exists.

(3) Oscilloscope assisted analysis

According to the manual of the protection IC, the delay of the protection circuit is different when the protection circuit detects overcurrent charging and overvoltage charging. The overcurrent charging protection usually has a delay of a few milliseconds to several tens milliseconds, while overvoltage charging protection is in second. According to the delay phenomenon, it can be judged whether the protection circuit has an overcurrent charging protection function.

Tested by oscilloscope and DC power, it can accurately verify the existence of overcurrent charging protection; if directly observe the reflection of DC power, it is easy to confuse the two protections.

Wearable device battery conclusion

The overcurrent charging protection function of lithium polymer battery products is not only the requirement of mandatory national standards for battery safety but also an important inspection item in the quality supervision and inspection of battery products. To test the protection function of overcurrent charging in the laboratory, it is necessary to add auxiliary judgment means on the basis of traditional test equipment. The detection method proposed by Grepow can accurately evaluate whether the battery protection circuit of wearable devices has overcurrent charging protection function.

How do Novel Battery Drive Innovation?

Today, everyone is tied to the high-speed train of technological progress. The introduction of new technology is almost always a competition between different models. Few people think about improving the quality of products or services so that consumers can have a better consumption experience. Because you haven’t settled down to make a good product yet, you’ve got the next competitor that’s going to disrupt the whole business model.

Every time you turn around, another company comes out with a breakthrough product that claims to have a profound impact on our lives and work. But how often do consumers actually experience disruptive innovation, as smartphones and cloud computing have done in our lives?

Many of the new products hitting the market today are not shocking but merely upgrades to their predecessors — perhaps with a smaller footprint, faster processors, more attractive packaging or additional features. These upgrades often overwhelm customers, with no compelling reason to justify the price increases that accompany them.

Consumers want disruptive technologies that can really improve their lives, whether at work, at home or in games. That’s what product manufacturers want to offer. So what’s holding them back?

Limitations of conventional batteries

The challenge is not to imagine exciting new products. Suppliers are good at this. Conversely, when it comes to consumer-centric electronics, the culprit is usually conventional, rigid and chunky batteries, which limit the batteries designed around them. But it doesn’t have to be this way.

The development of Grepow’s novel battery can stimulate a whole new level of product differentiation. Even after years of use, the batteries are still an unfamiliar concept to many product designers accustomed to conventional off-the-shelf energy storage in a rigid and fixed shape. Some people find it hard to believe that batteries are curved and still maintain their performance and safety. As a result, they designed their products around rigid battery parameters.

Novel battery commitments to flexibility

Fortunately, even for mass production, novel battery technologies are now available.

Despite the appeal of novel battery technology, we find ourselves having to reassure manufacturers that novel batteries are as reliable as their rigid ancestors. Our tests show that the novel battery has strong performance integrity. Not only can they be the ultra-thin battery, as thin as 0.4mm, but they can also be made into curved batteries, which have roughly the same capacity as non-curved batteries, without compromising performance.

This flexibility gives designers and engineers new latitude in hardware design: manufacturers can now place batteries in previously impossible or impractical Spaces. Take smartwatches. Engineers can embed special thin batteries in the watchband to increase the available energy or extend battery life, rather than just keep the battery in the head case.

With the growing demand for wearables and audio devices, smart clothing and other personal battery-powered products, consumers want more natural experiences. Unlike stationary off-the-shelf energy solutions offered in a limited range of dimensions and capacities, the novel battery can be customized to size, thickness, and capacity, enabling the development of smaller, lighter, and more comfortable products.

The other problem with rigid batteries is safety. Advances in electrolytes have made novel batteries safer. The latest polymer electrolyte is safer because it does not contain liquid that would leak if the battery were punctured or punctured – but it still has the same high ionic conductivity. This is a huge advantage for wearables makers in medical devices, sports equipment and fabrics, industrial applications and consumer electronics. Knowing that their devices contain more secure components not only gives manufacturers and consumers peace of mind but also increases adoption and usage.

Staying competitive in any technology-driven market requires constant innovation. In order to rise above adversity, companies must be fearless in accepting progress that stands out in the marketplace. Battery choice is critical to your hardware design – especially if the consumer will have direct access to the battery. The performance inherent in the next generation of novel batteries and enhanced security allows you to free up time to create disruptive products that provide compelling user experiences.

Novel Battery to Innovative Medical Technology Design

Advances in technology are pushing manufacturers to create desirable products that achieve greater functionality, greater convenience, and faster results. This is evident in all aspects of work and daily life, from consumer products such as smartphones and watches to the blockchain, cloud services, and enterprise-class smart factories. Medicine is no exception.

Trends in medical device design

Wearables are so common these days that we rarely think about them. Some smart bracelets and smartwatches have multiple tiny, sensitive sensors that can monitor your steps, heart rate, sleep, and even your menstrual cycle based on your input. A smartwatch that “monitors you” is accurate enough to see if the data it collects can identify abnormal heart rhythms, including those that cause severe arrhythmias.The blood vessels of the heart. However, in terms of the scale of the technology, the data collected by wearables is still in its infancy. The rise of artificial intelligence has foreshadowed the preventive and the paradigm shift of personalized medicine: provide sufficient for algorithm, good data, one day may be in danger of falling, swallowing problems, heart attacks and even your voice changes, which may indicate depression, Parkinson’s disease and other diseases of the disturbing attacks.

One of the major trends in the healthcare industry is the shift from public to private — from hospitals to homes. Even digital marketplace providers, such as Amazon, Google, Apple, Microsoft, and IBM, are moving into the home health space, bringing accessibility and affordability, according to Forbes.

The medical market shows encouraging growth. By 2023, the global medical device industry is expected to reach $409.5 billion, with a compound annual growth rate of 4.5 percent. From 2017 to 2023, the home-care medical device market is expected to grow at a compound annual growth rate of 7.1% to $35 million. With this changing healthcare architecture, the need for personalized and connected devices that can continuously track user data and transmit it to network systems and clinicians is growing rapidly. Thus, two major trends driving the design of medical devices are worth exploring: personalization and the complexity of driving the Internet of things.

The necessity of equipment design

What kind of products are needed to meet the needs of personalized, interconnected medicine? Smart wearables and the Internet of things devices not only make it easier to track users’ biometrics and progress in hospitals and homes but also make home-care treatments more effective and thus possible.

Advanced user-centered devices also allow the health care industry to progressively analyze current health conditions and accumulate data on preventive measures. In this way, device sensors are used not only to monitor the recovery of sick patients but also to capture abnormal data or symptoms in people who are not yet sick or injured.

What if there’s a medical device that’s rich in features that can monitor patients and provide preventative alerts, but can be awkward to wear or walk around for older, very young patients or others?If they don’t use it, who will go wrong and their health will suffer as a result?Not the user.

If people don’t use the product properly, the problem lies with the device designer. Clearly, wearables need to be comfortable to encourage regular use. If consumers do not wear them regularly, fewer data will be collected. As a result, they will receive worthless or, worse, inaccurate analyses and recommendations that harm patient care. In short, intuitive design will increase adoption rates and the likelihood of successful treatment.

The battery barrier

The need for personalization and the use of IoT connected devices with greater capabilities that need to run continuously present device design engineers with new challenges — and raises concerns about the limitations of today’s medical batteries.

The rigid, bulky shape of the battery often hampers the comfort of wearables and the availability of internet-of-things devices. Smartwatches and other smart devices are so popular because they improve and improve everyday life. However, rigid and bulky batteries are thick and unbending, so forming them into well-designed, portable and practical products is challenging.

Advances in batteries have broken down barriers

How do we address the challenge of batteries as a barrier to the Internet of things and wearable medical devices? By having a more compliant adaptive shape factor. They must be thin, even curved, and powerful and rechargeable, so they can be used to design compelling wearable and intuitive wearable devices.

The good news is that the new generation of lithium-ion batteries has the required flexibility.

For example, Grepow’s novel battery comes in a variety of shapes, such as round, curved, triangular, hexagonal, and so on. The capacity of the curved battery is basically the same as that of the non-curved battery. Tests like this show that device designers don’t have to sacrifice performance to improve the flexibility of energy storage.

This flexibility is essential for bendable or curved products. This is also important for non-wearable devices, which make it easy to integrate batteries into existing devices and turn them into smart, internet-connected devices. The novel battery is as thin as 0.4mm to 8mm. This allows them to be seamless in the device and achieve a comfortable feeling of wearing.

Look for the customizable novel battery that can be supplied in different sizes, shapes, and capacities depending on the specific needs of the device manufacturer. With this capability, device designers are no longer constrained by the fixed size and shape of conventional batteries. They have greater freedom to design innovative, user-friendly medical and Internet of things devices.

Safety is another important factor to consider when evaluating batteries for medical and other devices. Safety is clearly a major concern for manufacturers and consumers. Especially with wearable devices that touch the human body, it’s important to make sure that dangerous battery components don’t pose a risk to the user.

Typically, lithium-ion batteries contain liquid, solid or gel electrolytes. The most common form of electrolyte used in such batteries is liquid, which can leak and catch fire when it gets too hot. This is a major cause of many accidents, and understandably makes liquid-electrolyte batteries the second-best choice for the next generation of medical devices and smart wearables.

Solid electrolytes, on the other hand, are safer because they do not burn. However, due to the low ionic activity of the electrolyte, this safety function cancels out the performance. Moreover, solid-state ceramic batteries do not provide the flexibility needed for wearables and innovative IoT applications.

Gel electrolytes offer the best of both worlds for medical wearables and the Internet of things while providing security and flexibility. Because of the shape of the gel, there is no electrolyte leakage even if the device is punctured or punctured, so the risk to the consumer is minimal.

A new day in the life

If the novel batteries were integrated into his medical wearable device, how would the patient’s daily life improve?

If the patient’s wristband is powered by a thin, rechargeable, curved (and therefore unobstructed) battery, he will wear it comfortably. It will be his habit to keep on.

If a patient happens to have a stroke while driving, his wrist monitor can indicate a road break and sensors in the tires (which can also be powered by novel battery) to safely stop the vehicle. The monitor also alerts doctors and sends text messages to her daughter.

Patients will also wear a smart transdermal patch powered by an ultra-thin battery that seamlessly fits the arm. The patch will immediately release an emergency dose of antihypertensive medication and write it into the patient’s 24/7 medication record.

A patient’s smart medical wearable device can also help with doctor visits. His wristband sends blood pressure readings to nurses, while the smart patch drug releases the necessary dose as planned and collects accurate data on hospital servers. If a patient’s blood pressure exceeds the normal range, an alert will be sent to the doctor.

The patient can also be treated by wearing a smart band powered by a flexible rechargeable novel battery that sends continuous progress information to her physical therapist and doctor. spends less time on office visits and more time on recovery.

As you can see, the development of thin, curved batteries is breaking free from the constraints of design engineers. With batteries no longer a limiting factor, medical device manufacturers now have the right energy solutions to deliver the most advanced devices in a personalized and internet-driven complexity driven healthcare industry. With novel battery, they are free to innovate extremely comfortable, reliable and safe smart, high-performance and feature-rich connected products. The possibilities are endless.

The Secret to Special Batteries for IoT Devices

Nowadays, it’s hard to find an unconnected device anywhere. According to Stringify CTO Dave Evans, another 127 “things” are connected to the Internet every second, and Gartner predicts there will be 25 billion IoT devices by 2021.

Connected devices are valuable only for the data they collect, the knowledge they impart, and the actions they take from the analysis of the data. This applies not only to larger, high-profile applications such as smart homes and cities but also to a growing number of smaller IoT applications. These smaller applications (such as smart tags, smart packaging, smart pills, smart tags, smart CARDS, smart medical devices, and various wearable devices) affect life and business every day.

As more and more things become connected devices, the type of power they use comes into play.

They play a surprisingly large role in how effectively they sense and transmit data, and how available (and therefore frequently used) they are. By virtue of their thick, rigid conventions, manufacturers of off-the-shelf batteries often suffer from design constraints that limit their success.

Advances in energy storage could make devices truly usable

Energy storage solutions are more advanced than many manufacturers realize. New battery innovations give manufacturers the freedom to create truly user-friendly IoT devices for efficient data sensing and transmission. Lightweight, thin, flexible and flexible next-generation high-performance battery solutions can be seamlessly integrated into connected devices. This results in a more aesthetically pleasing design of the device’s hardware, which provides better user experience and higher comfort, and ultimately leads to wider market adoption.

For example, if a patch used for monitoring biometric features or for therapeutic purposes is embedded in a thick, rigid battery unit, the user is uncomfortable to wear it. This discomfort limits its use time, resulting in a small amount of data collection that is not conducive to analysis. However, if the patch has a seamless integration of thin and flexible batteries, it will not interfere with their daily activities. In fact, the user is not even aware of wearing it. This will naturally increase usage. As each consumer USES patches more frequently, more data can be collected and more valuable feedback can be provided.

Key advances in special batteries

So how flexible are special batteries? Very much. Even if the battery is curved, the battery still has the same charge-discharge performance as the non-curved battery. For devices that need to be bent or bendable, this flexibility must be provided and ultimately help consumers to use them comfortably.

Other major advances in special batteries are related to weight, safety, customization, and thinness.
The battery thickness can be as low as 0.4mm. This thickness is useful for sensors, smart CARDS, wristbands and other applications where weight and thickness are critical to success. These functions are also key to enabling the battery to fit into the narrow space in the device’s hardware.

The next generation of batteries must also be safer. Even if manufacturers make great efforts to ensure the battery’s durability and international safety tests are required, this is no guarantee that the battery will not overheat, explode or leak. Special rechargeable batteries made with lithium polymer electrolyte technology have higher safety than those made with liquid electrolyte. The electrolytes in special batteries are highly resistant to heat and do not leak when punctured.

Manufacturers can now choose to customize special flexible batteries to make better use of the space and hardware design of their devices, rather than using off-the-shelf rigid batteries. Engineers and designers can now leverage battery manufacturers’ custom services to create flexible battery solutions without having to revisit their designs at the end of the creation process because these off-the-shelf batteries are not suitable for optimized product designs. Best meets its size, capacity, thickness and shape requirements, and provides a better user experience.

As many things become “smart”, competition among makers of connected devices is fiercer than ever.
The type of battery that device makers use to power or transmit data to smart devices or their components plays an important role in the innovation and utility of their devices, as well as the purchasing power to attract users.

The next generation of special batteries is key to delivering the highly available, aesthetically pleasing and reliably connected devices that give forward-looking IoT device makers a competitive advantage.

How Long Does the Battery on a Smartwatch Last?

With the development of smartwatches, people are increasingly using smart products, so the development of smartwatches is becoming more and more prosperous. Although smartwatches have the power of many traditional watches, it also has a huge weakness, which is smartwatch battery life.

Smartwatch battery life problem

The smartwatches sold in the market have different tolerances in terms of battery life, and the length is 5-7 days and the hours are short. For Smartwatches, even for up to 5-7 days, it is still difficult to meet the needs of ordinary users. After all, Smartwatches first exist as watches.

Since 2013, lithium-ion polymer batteries have gradually replaced ordinary liquid lithium batteries. Since then, the energy density of smartphones has made a huge leap. In 2013-2014, many smartphone manufacturers began to build internal batteries, and the operating voltage of smartphone batteries began to increase from 3.7V to 3.8V. Smartphone battery specific capacity (also known as gram capacity, refers to the amount of electricity per gram of battery) ) reached a peak again.

Even so, the battery life of the smartphone has also encountered a “stay”. In the face of the high power consumption of today’s smartphones, lithium batteries have become a bit “incapable”.

Of course, smartphone manufacturers are also constantly looking for new ways to improve battery life, expand battery capacity, charge through external power sources, and even hope to significantly improve battery life by replacing fuel cells and bio-batteries with new battery technologies.

Under the nurturing of intelligent manufacturers, users who use smartphones have become accustomed to “one day a charge” or even “more than one day.” However, Smartwatches cannot be treated in the same way. Not to mention the tedious “one-day charge”. If it is a user of a Smartwatch, who would like to charge it with an external power supply every day? How to make consumers more convenient to use is a problem that Smartwatch manufacturers must solve.

Smartwatch function

The current smartwatch battery capacity on the market ranges from 300mAh to 500mAh. The size of the battery used in the watch is related to the size and structure of the watch itself and is affected by the watch system and functions. Can do it for a long time, and really use it, I feel that there is no electricity! Let’s take a look at the power consumption of this function of the Smartwatch! The following is calculated by the 500mAh Smartwatch battery:

Sports step

The Smartwatch’s main sports function, when other functions are not open, the step-by-step function is turned on all the time, from morning to night to sleep, in the case of normal exercise (according to 13000 steps), it can consume about 30% of the Smartwatch power, so Although the sports step is the main function, it is not the most power-hungry.

Connect mobile phone Bluetooth

Many Smartwatches can match the mobile phone’s Bluetooth before using the APP for message push. The Bluetooth call function, if there are few messages pushed, can see that the basic power consumption is very small, but if you are a chat enthusiast, there is a lot of news all day long. In particular, when Bluetooth is connected to the phone, the power consumption of the Smartwatch is gradually increasing.

Heart rate monitoring

Occasionally measure the heart rate, you can ignore the power consumption. Some Smartwatches have a heart rate monitoring in real-time around the clock, so this is careful, the Smartwatch battery can be used up in a few hours, after all, the heart rate is dependent on the light, the continuous light and feedback, resulting in Smartwatches consume very much electricity Big.

GPS positioning

Smartwatch battery is absolutely killer, even on large-capacity mobile phones, we can see, let alone small watches. If the watch does not turn off the GPS, basically one hour, you need to charge. Therefore, the GPS intelligence of the watch is used as an auxiliary device and cannot always be kept open.

Elevation compass, etc.

These are always open and very power-hungry. Because of the constant measurement and acquisition of data, it is no doubt that heart rate real-time monitoring and GPS are the same.

Other accessibility features

Other auxiliary functions, the basic power consumption can be ignored.

Through the above, it can be polished. Basically, the culprit of Smartwatch power consumption is the more advanced functions of some mobile phones, but the functions of outdoor sports itself, but not counting power. So if it is purely for outdoor sports, then the Smartwatch function is as simple as possible. If you want to feel the highlights of the smart wear era, you can choose the Android watch, but also based on the sacrifice of power consumption.

In the previous technology, every time the electronic exhibition, the battery has not yet had a good solution. Until GREPOW’s custom battery solutions include a Smartwatch battery solution.
