Abstract
一种蓄电池过放电保护装置，其壳体内设有用于对电池的用电回路进行断开控制以保护电池防止过放电的切断开关D1、用于确保电池在正常使用过程中不会突然断开使用回路的电磁铁C1、用于控制切断开关D1启动的电磁铁C3、用于根据电池在近似开路状态下的实际电压是否低于预设的保护电压从而控制电磁铁C3是否通电的电磁铁C2。当电池在整车上充电或正常使用放电时，本实用新型始终处于使用状态，不会对电池充放电产生影响；当电池在整车上处于未使用状态时，整车回路只有暗电流，此时本实用新型会根据电池电压自发判定是否对电池进行断电保护，在车辆长期库存过程中能根据电池电压自动断开负极连接线，避免了电池的过放电，且不会影响车辆的正常使用过程。
