电动汽车用铅酸蓄电池智能管理系统

Intelligent Management System of Lead-Acid Battery for Electric Vehicle

绍了铅酸蓄电池的特点且设计出一套完整的基于P87C591单片机的铅酸蓄电池数字智能管理系统,包括铅酸蓄电池电压、充放电电流、内阻、剩余容量及电池温度等重要参数的检测,解决了传统充电方式中电池过充放电、寿命低等缺点,具有很好的应用前景,模块实现了对动力电池的监控和保护。具有接线简单、效率高、易于与整车控制网络相兼容等优势。

The characteristics of lead acid battery are introduced and a digital intelligent management system based on P87C591 microcontroller is designed in this paper, including the detection of battery voltage, charge/ discharge current, internal resistance, spare capacity, temperature, and so on. The single uniform charging solves the present problems such as over charge/discharge and short life, so it shows a good application prospect. This module realizes monitoring, control and protection for the battery. And this system has the advantages： simple connection, high efficiency and compatibility with the control network of the whole vehicle.
