Abstract

Gathering real-time tracking for Charge-discharge voltage and temperature values of lithium iron phosphate battery.We can take full advantage of the charge-discharge characteristics of the battery to optimize battery usage, and ultimately improve the efficiency of the battery.The battery performance test system designed in this paper is based on STC12C5A60S2 microcontroller as the microprocessor, connecting the two pieces of AD7888 chip to achieve A/D acquisition and conversion, temperature measurement is connected to the temperature sensor through analog switches CD4051, collection of data via USB bus communications chips CH340T transferred to the host computer.The internal resistance of the battery can be calculated according to the difference between the former DC discharge and post-discharge voltage, obtaining the battery capacity by using the charge-discharge current and the time,the results show:the charge and discharge of the current and voltage difference caused by its internal resistance cannot be ignored and need to real-time correction; if need fast charging, select the constant current mode; when batteries are being stored for a long time, the battery voltage should be remained in the most stable discharge interval to ensure stable performance of the battery.
