In order to better control and monitor the DC power supply, a microcomputers control DC power charge and discharge device based on the single chip 80C196 is introduced. The device has floating charge, charge, inverter discharge and automatically select the charging mode according to battery status. Operation proved that it has the characteristics of simple hardware circuit, high control precision, flexible operation, strong anti-interference ability and high performance-price ratio. It takes advantage of the microcontroller’s powerful judgment and logic computing power and software flexibility. The test of the battery state shows that the computer-controlled charge-discharge device can automatically charge the battery and protect it intelligently, keep the bus voltage of the battery and the DC system in a good running state all the time, prolong the service life of the battery, simplify the operation and improve The reliability of DC system operation
