Management system of power battery for mixed-power automobile

This invention puts forward a kind of power battery's management system of mixed power vehicle. It is comprised by two subsystems: picking circuit board and master circuit board. The picking circuit board's single unit cell voltage picking module picking circuit board and total cell voltage /electric current picking module are connected with CPU's I/O after multicircuit switch and the A/D conversion chips. The picking circuit board and the master circuit board carry on communication through the CAN total line communication module. The address port and the data port of the master circuit board's not volatility data memory module have the conjunction with CPU's I/O. The reading port and writing port connect with CPU's reading port and writing port. And CPU's I/O separately connects with CA of strong electricity protection module, temperature control module and malfunction alarm module. This invention can improve the system's voltage picking accuracy and speed. It can improve the stability of data sending in complicated actual work condition. Furthermore, it improves the accuracy of single unit cell voltage collect and the anti- interference in the process of voltage collect.
