Abstract :
Appropriate monitoring technology for energy storage system plays an important role in electric vehicles. A distributed data acquisition system was developed. The system which communicates with host unit via CAN-bus is composed of 36 data acquisition units which monitoring cells parameters. The distributed topology could effectively improve the speed of data acquisition. A calibration algorithm for current sensor was developed to increase the estimation precision of SOC. The monitoring system was implemented in a super-capacitor pure electric urban bus. Experimental results demonstrated that the distributed data acquisition system performs well in monitoring the system and cell voltage, current and temperature.
