Abstract
A multi-channel high precision test system for performance of rechargeable battery based on the AT89S52 microcontroller is presented. The system uses 24-bit ADC LTC2498, 16-bit DAC MAX541 and low temperature drift, low-noise voltage source MAX6033 to achieve high precision and high accuracy test. It realizes the functions of testing rechargeable battery performance, such as constant current charge, constant voltage charge and constant current discharge. The hardware and software of this system are also introduced.
