Function testing device and method for small electric quantity extra battery

Abstract

The invention discloses a device for testing the function of a small capacity spare battery and the method thereof, wherein the device comprises a spare battery unit 101, a volatile memory unit 102, a micro processing unit 103 and a measurement unit 104, wherein the spare battery unit 101 and the volatile memory unit are connected through an interface of the spare battery unit; when a main power supply is out of work or has power down, the volatile memory unit 102 shifts automatically to the spare battery unit to be supplied with power; the volatile memory unit 102 has the function of storing data, or can provides instant messaging; the micro processing unit 103 is used for reading the voltage measurement information of the spare battery of the measurement unit 104 and the data information of the volatile memory unit 102, judges if the spare battery operates normally and reports the result; the measurement unit is used to shirt the voltage of the spare battery and performs measurement. The invention judges the working state of the spare battery according to the voltage signals of the spare battery and determines simply and effectively the consumption of the battery according to the voltage.

General communication main control boards, PC main boards, personal handheld electronic products and other electronic products mostly use backup batteries to provide low-voltage volatile memory to save certain configuration...

AI Technical Summary

Problems solved by technology

This method is more suitable for testing batteries with large power such as notebook batteries, but for testing small-capacity batteries such as button batteries, it will cause relatively large losses, which will seriously affect battery life.

Moreover, software is required to monitor the voltage and current of the battery in real time and accumulate them, which consumes a lot of power.
