摘　　要：介绍一种应用于低压直流系统的蓄电池短路保护电路.该电路通过检测放电回路电流来判断短路与否,并具有可控释放短路保护的功能;该电路简单、实用且有较强的稳定性和适应性.还验证了在容性负载情况下能使系统正常启动所设置的参数,该蓄电池短路保护电路已在某公司产品中大量使用.Low voltage DC system＇s short-circuit protection circuit for battery packs was introduced in the paper. This circuit determined the situation of short-circuit by detecting the anomalous discharge current, and was able to release the short-circuit protection when it was commanded by a control signal. With strong stability and applicability, it was simple and practical. In addition, appropriate circuit parameters for different capacitive load was verified by experiments and the short- circuit protection circuit was applied to the actual products.
