The invention provides a short circuit detection device. The device comprises at least one charging gun; a short-circuit detection unit electrically connected with the charging gun and used for detecting whether the output end of the charging gun is short-circuited or not; and a main control board electrically connected with the short circuit detection unit and used for controlling the charging gun to normally charge under the condition that the short circuit detection unit detects that the output end of the charging gun is not short-circuited and controlling the charging gun to stop chargingunder the condition that the short circuit detection unit detects that the output end of the charging gun is short-circuited. According to the scheme, the short-circuit detection unit can detect whether the output end of at least one charging gun is short-circuited or not, the main control board controls the charging guns to normally charge or stop charging according to a detection result of the short-circuit detection unit, and multi-gun output short-circuit detection is achieved.
本申请提供了一种短路检测装置。该装置包括:至少一个充电枪;短路检测单元,与充电枪电连接,用于检测充电枪的输出端是否发生短路;主控制板,与短路检测单元电连接,用于在短路检测单元检测到充电枪的输出端未发生短路的情况下,控制充电枪正常充电,在短路检测单元检测到充电枪输出端发生短路的情况下,控制充电枪停止充电。本方案中短路检测单元可以检测至少一个充电枪输出端是否发生短路,主控制板根据短路检测单元的检测结果,控制充电枪正常充电或者停止充电,实现了多枪输出短路检测。
