The invention discloses a power supply management system with multiple protection. The power supply management system comprises a battery pack, a current acquisition module, a voltage acquisition module, a fuse module, a switch module, a secondary protection module, a temperature acquisition module, a single-section voltage acquisition module, a front-end module and a main control module; by realizing the protection functions of preventing overcharge, overdischarge, overcurrent, short circuit and high-temperature charge and discharge, the lithium battery is prevented from being overcharged andoverdischarged in the charging and discharging process, the service life of the battery is prolonged, and the lithium battery pack is protected to be in a good running and working state; through theprotection functions of over-current protection, short-circuit protection and high-temperature charging and discharging, the lithium battery pack is prevented from being abnormal in time in the usingprocess, further serious abnormity is avoided, and therefore the using safety is achieved.

    本发明公开了一种具有多重保护的电源管理系统,包括:电池组;电流采集模块、电压采集模块、保险模块、开关模块、二次保护模块、温度采集模块、单节电压采集模块、前端模块以及主控模块,通过实现防止过充、过放、过流、短路以及高温充放电的保护功能,使得锂电池在充放电过程中不会出现过充电、过放电的状态,保护电池的使用寿命,保护锂电池组处于良好的运行工作状态;通过实现的防止过流、短路保护以及高温充放电的保护功能,保护锂电池组在使用过程中出现异常时,及时进行阻止,避免异常的进一步严重,从而实现使用的安全性。
