The embodiment of the invention relates to the technical field of charging piles, and discloses a charging host and a charging pile. The charging host comprises a power output unit, a switch matrix unit, a control unit and a switch interlocking unit. Each switch in the switch matrix unit is provided with a switch number. The switch interlocking unit comprises at least two interlocking circuits, the interlocking circuits which anchor the same switch number but belong to different switch interlocking units are electrically connected to the same locking bus, and the target interlocking circuit responds to an action signal, controls a target switch to act and transmits an interlocking signal through the locking bus. The reference interlock circuit controls the reference switch not to act in response to the interlock signal. According to the embodiment of the invention, the short circuit phenomenon caused by simultaneous action of different switches in the same power output unit anchored by different switch matrix units is avoided, the interlocking operation is completed by adopting a hardware circuit mode, and the interlocking efficiency is high.

    本申请实施例涉及充电桩技术领域,公开一种充电主机及充电桩。充电主机包括功率输出单元、开关矩阵单元、控制单元及开关互锁单元。开关矩阵单元中各开关都配置开关编号。开关互锁单元包括至少两个互锁电路,锚定相同开关编号但分属不同开关互锁单元的各互锁电路电连接在同一条闭锁总线上,目标互锁电路响应动作信号,控制目标开关进行动作且通过闭锁总线传输互锁信号,参考互锁电路响应互锁信号控制参考开关不进行动作。本实施例避免分属不同开关矩阵单元却锚定同一个功率输出单元中不同开关出现同时动作而出现短路现象,并采用硬件电路方式完成上述互锁操作,互锁效率高。
