一种具有自锁功能的矿用蓄电池组低静态电流放电保护电路
A low static current discharge protection circuit for mining battery packs with self-locking function
摘要
Abstract
A low static current discharge protection circuit for mining battery packs with self-locking function has been designed to address the problems of high self loss,unreliable discharge protection,and serious self consumption after protection in the discharge protection circuit of mining equipment battery packs.The protection principles of three common discharge protection circuits for bat-tery packs were introduced,as well as the function of low static current discharge protection circuits with self-locking function;de-tailed discussions were given on the design of each unit in the protection circuit,as well as two key technologies:protection window locking and static low-power processing.Verified by testing:the working current of the discharge protection circuit before protec-tion is not greater than 2.5 mA;the static current after protection shall is not more than 15 μA,and the protection reliability rate is 100%;the safety performance and safe storage time of the mine storage battery are effectively guaranteed.关键词
