基于水平铅布电池的模块化电池管理系统的设计和研究

被誉为"铅酸蓄电池的又一次革命"的水平铅布电池,具有很高的比能量、比功率和循环寿命,从而在电动汽车中得到很好的应用。然而,如果在运行中不能很好的管理,电池会产生如过充、过放和电压不平衡等很严重的问题。因此,本文研究了电池管理系统的类型和基本功能,基于水平铅布电池设计了一种模块化的电池管理系统(BMS)。试验结果表明,该系统节省了布线、降低了成本和质量、增强了灵活性。

The design and research of modular battery management systems based on the horizon lead-acid battery

Horizon lead-acid battery,which is called"another revolutionary of the lead-acid battery",has high specific energy,specific power and cycle life,and greatly applies to the electric vehichles.However,it may come into being serious problems if the batteries get improper management during the operation,such as over-charging,over-discharging,imbalance of voltage among the cells.So,this paper studies the types and basic functions of the BMS,designs a modular BMS based on the horizon lead-acid batteries.The experimental results show that the system reduces the size and weight of the wiring harness,lowers the cost and enhances the flexibility.
