摘要
由于电化学反应的特殊性、动力电池的各项参数都受到一定的范围限制。电池管理系统(Battery Management System,简称BMS)建立在对电池特性研究的基础上,保障电池在合理的参数范围内工作,准确预测电池的荷电状态(State of Charge,简称SOC),同时对电池的健康状态(State of Health,简称SOH)做出估计。BMS包括4个控制单元,即单体控制单元CCU、温度控制单元TCU、安全控制单元SCU、电池控制单元BCU。通过对电池特性、SOH估计、SOC预测、温度管理和故障诊断的分析,给出了相应的实现方法和控制策略。
The parameters of power batteries have certain range limitations because of the special nature of electrochemistry reaction in the using course of batteries.Battery management system (BMS) is established on the basis of characteristics of the batteries, to protects the batteries working within the reasonable parameters, predicts the State of charge (SOC) of the batteries accurately, meanwhile,estimates the state of ealth (SOH) of the batteries.BMS is composed of four control units : cell control unit ( C C U ), temperature control unit (TCU), security control unit (SC U ) and battery control unit ( BC U ). Through the analysis of the characteristic research of the batteries, SOH estimation, SOC forecast, temperature management and fault diagnosis, corresponding control strategies and implementation methods are presented.
