The invention discloses a high-voltage control circuit of an automobile air conditioner, which comprises a main relay, a pre-charging relay, a pre-charging resistor and an all-in-one controller, an air conditioner control circuit is arranged in the all-in-one controller, a protective resistor is arranged on an anode line of the air conditioner control circuit, the main relay is connected to an anode line of the all-in-one controller, and the pre-charging relay is connected to the all-in-one controller. The pre-charging relay and the pre-charging resistor are connected in series and then are connected in parallel with the main relay. According to the invention, an all-in-one internal air conditioner high-voltage relay is canceled, and a fuse is reserved And a communication protocol is changed, so that the air conditioner panel automatically controls the air conditioner to start and shut down.

    本发明公开了一种汽车空调的高压控制电路,包括主继电器、预充继电器、预充电阻和内部设有空调控制电路的多合一控制器,在空调控制电路的正极线路上设有保护电阻,所述主继电器连接在多合一控制器的正极线路上,预充继电器和预充电阻串联后与主继电器相互并联。本发明取消多合一内部的空调高压继电器、保留保险。更改通讯协议,这样空调面板自行控制空调启动关机。
