摘要
采用单节锂电池保护芯片设计电池保护板,对任意串联数的成组锂电池进行过充、过放、过流、短路保护,充电过程中实现整组电池均衡充电。在Simulink环境下,用逻辑模块和延时模块等模拟了保护芯片工作的逻辑,实现了整个保护电路工作情况的仿真。实验和工业应用结果表明,该均充保护系统具有应用灵活、稳定可靠等优点,均衡充电误差小于50 mV。
The battery protection board was designed with single cell lithium-ion battery protection chips.It can provide over voltage,under voltage,over current and short circuit in discharge protection function for any package cells in series.Furthermore,it can realize equalizing charge for the whole package battery.The simulation for the working state of the protection circuit is achieved by using some logical modules,delay modules and so on in Simulink circumstance.Experiment and industry application results show that the equalizing charge and protection system has the features such as flexible application,stabilization,credibility,etc.The equalizing charge errors are less than 50 mV.
