面向低速电动汽车的锂电池保护系统设计
|
摘要
在低速电动汽车的动力电池选择上,锂离子电池以其独有的优势正在逐渐走向低速电动汽车的市场。针对锂离子电池充放电过程中发生的充电过压、充电过流、放电过流以及短路等情况,以ML5238作为电池采集芯片,以恩智浦的MKE06Z64作为主控芯片,设计了一套锂电池保护系统。本系统实现对锂离子电池充放电的电流、电压检测和显示,并且对电池的充放电进行保护,同时对充电过程发生的电池不均衡现象设计了电池的均衡功能。
In the low-speed electric vehicle power battery selection, lithium-ion battery with its unique advantages aregradually moving towards low-speed electric vehicle market. In view of charging overvoltage, charging overcurrent,discharge overcurrent and short circuit in the process of charging and discharging of Li ion battery, taking ML5238 asthe battery acquisition chip, and Freescale's MKE06 Z64 as the master chip, a lithium battery protection system wasdesigned. Through the system, the current and voltage of Li ion battery charging and discharging could be detectedand displayed, and the battery while charging and discharging at the same time could be protected. Also a batteryballance function for the battery imbalance was designed.
