Abstract :
A battery management system (BMS) based on the CAN-bus was designed for the Li-ion battery pack which consisted of many series-connected battery cells and was distributed dispersedly on the electric vehicle (EV). The BMS consisted of one master module and several sampling modules. The hardware design of the sampling circuit and the CAN expanding circuit was introduced. The strategies of the battery SOC (state of charge) estimation and the battery safety management were also presented.
