Description
Summary:To study the operation characteristics of light electric vehicle, the paper developed a battery management system of light electric vehicle. The system mainly contains battery protection module, battery equalization module, battery data management module. It could be real-time monitoring the operation parameters of batteries effectively: rotational speed of motor, State of Charge (SOC) of the batteries, voltage and current of the batteries, temperature of the feature points in the battery package. It can also equal the voltage inconsistency between different batteries and realize the protection and alarm functions etc. The results showed, the system ran stable, reliable, and met the precision requirements, thereby the system lays a foundation for the engineering application.
