The invention discloses a direct current charger shutdown detection control system, relates to the technical field of direct current charger shutdown control, and solves the technical problems that in the prior art, it cannot be guaranteed that the output current is reduced to zero when an output relay is disconnected, the timeliness of output disconnection cannot be guaranteed, and the output relay is prone to being damaged. A control module controls on-off of a power module and on-off of an output relay; the power module detects a signal S3 formed by the shutdown circuit and performs shutdown processing in time; in the process that the control module detects the shutdown signal S1, the shutdown signal S1 forms a signal S3 through the shutdown circuit, the power module detects the signal S3 at the same time, and therefore it is guaranteed that after the control module conducts filtering processing on the shutdown signal S1 and prepares to disconnect an output relay, the power module also completes filtering detection processing on the signal S3 and shuts down; and the fault problem caused by the damage of the output relay is avoided.

    本发明公开了一种直流充电机停机检测控制系统,涉及直流充电机停机控制技术领域,解决了现有技术无法保证断开输出继电器时输出电流已经降为0,以及无法保证输出断开的及时性,易导致输出继电器损坏的技术问题;本发明控制模块控制功率模块的开关机和输出继电器的通断;功率模块检测停机电路形成的信号S3,及时进行关机处理;实现了控制模块检测停机信号S1过程中,停机信号S1通过停机电路形成信号S3,功率模块同时在检测信号S3,从而保证当控制模块对停机信号S1进行滤波处理后,并准备断开输出继电器时,功率模块也完成对信号S3的滤波检测处理并关机,避免因输出继电器损坏而导致故障问题。
