一种蓄电池充放电保护装置的设计

Design of Battery Charging and Discharging Protection Device

针对蓄电池经常处于过充电或过放电的使用状态,会造成蓄电池本身的化学特性改变,缩短其使用寿命的问题,提出设计一种保护电路装置,即对电池的电量进行实时检测,一旦检测到电量过低时,立即将电池与外部负载电路断开,对电池起到保护作用。该装置经工程实践项目中应用,保护电路很好地改善了装置的整体性能,取得了较好的效果。

Aiming at the battery often in the state of charging or discharging, will change the chemical characteristics of the battery and shorten the service time, designs one circuit protection device to test the quantity of electric charge real-time. Once detects the low power, cut off the battery from the outer loading circuit immediately, which protects the battery effectively. This design applies in the project, improves the whole performance and protects the circuit, which gains good effect.
