Wearable Device Power Solution


Wearable technology engineers and designers face the same challenge all the time — how do you design a battery, which is often the largest single component of a wearable device, to keep it beautiful and functional? Batteries are heavy. They are clunky and unwieldy – but they are essential to keeping every technology going.

What is Wearable Power?

Unfortunately, when we jog, we can’t plug in the power, so battery power is an absolutely essential part of any wearable technology. Our smartphones need charging, our fitness trackers, our wearable cameras, and camcorders. Without power, we can tie wearable gems to our legs and wrists. This is where wearable battery comes in. The wearable battery is connected to the wearer’s clothing or straps and provides the same amount of energy as they do for other wearable technologies. They are small, light, unobtrusive, and carry enough power to power all your wearable devices.

In wearable devices, the battery is usually very small (for example, 100 mAh), and the device takes several days or even weeks without charging, so power consumption is a key design consideration. Therefore, high power conversion efficiency will be a key design element.

Stylish wrist-worn wearable devices need to be kept to a minimum size in order to maintain their cool features. This drives a high level of full device integration including batteries. In addition, wearable devices can employ a novel battery.

The Biggest Challenge For Wearable Tech

1. The battery intelligent management system should have almost all types of safety design, including overvoltage protection, overcurrent protection, overtemperature protection, short circuit protection, and low-temperature charging, even when the power solution size must be kept very small. is also like this.

2. Because the wearable battery is small, the need for charging accuracy is increased, making charging these small batteries is not an easy task. The charger must be able to provide a smaller charge cut-off current. In other words, the accuracy of the charger should be higher, up to mA level. For example, in a smartphone system, the normal charging current of a 2,000 mAh battery is 1.2 A (0.6 C), and the charging cut-off current should be 1/10 to 1/20 of the normal charging current, that is, 120 mA to 60 mA.
However, in the bracelet, since the battery capacity may be 100 mAh, the normal charging current will be 60 mA, and the charging cut-off current should be 6 mA to 3 mA. Charger devices that meet this requirement are difficult to find.

3. Wearable devices should have long battery life. Often, consumers are not happy if they charge their devices every day. In the current situation where many of the best smartphones have to be recharged in a day or two, end users are clearly looking forward to improvements. The entire power management should be able to provide a highly efficient power supply.

4. In wearable devices, the failure point of many products is the charging/signal connector because of the relationship between humidity and corrosion.

Wearable Power Products

In response to these design challenges, Grepow batteries have taken corresponding measures to gradually solve the battery runtime requirements based on their cutting-edge battery production technology. We need to use a novel battery while using a wearable device. The novel battery power density is increased in that it takes longer to convert to available power.

Novel battery

With the great success of wearable applications such as smart shoes and Bluetooth headsets, small batteries have become the decisive choice for wearable devices. Wearable devices can be used in any area, and some battery designs are limited to size or special shape requirements. Grepow wearable battery has a small size, irregular shape, wide application temperature range (-40 ° C ~ 50 ° C or -20 ° C ~ 60 ° C), etc., is a customer custom power solutions, is also a development trend.
