Battery management system with field-effect tube breakdown detection function

一种具有场效应管击穿检测的电池管理系统

Abstract

本发明涉及一种具有场效应管击穿检测的电池管理系统。解决现有技术中电池管理系统功率开关管容易被击穿而造成电池损坏,以及并未具有对保护失效后做出处理的问题。系统包括电池组、开关模块、采样电阻、电源管理模块、中央处理模块、单体电压采集接口模块、单体电压采集IC模块、报警模块,本发明的优点是具有场效应管击穿检测功能,能够及时发现控制开关模块异常情况,并具有报警模块能及时进行报警,提醒用户需及时维修,防止电池组在失控的情况下继续使用,导致维修的发生,而且还能够对控制开关模块失效进行进一步保护处理,保护了电池。
The invention relates to a battery management system with a field-effect tube breakdown detection function. The system solves the problems that in the prior art, a battery is damaged due to the fact that a power switch tube of a battery management system is prone to being broken down, and the battery management system takes no processing measures after protection failure. The system comprises a battery pack, a switch module, a sampling resistor, a power management module, a center processing module, a single voltage collection port module, a single voltage collection IC module and a warning module. The battery management system has the advantages that the field-effect tube breakdown detection function is achieved, abnormal situations of the control switch module can be detected in time, the system has the warning module and can send out a warning in time so that a user can be reminded of maintaining the switch module in time, the situation that the battery pack continues to be used after being out of control and accordingly maintenance is needed is avoided, and besides, further protection processing can be carried out on the failed control switch module and accordingly the battery is protected.
