Embodiment 1
[0028] Such as figure 1 , this embodiment proposes an electric vehicle charging socket, including a socket, a trigger switch, a controller, a radio frequency communication module and a current detection module (not described in figure 1 show).
[0029] The socket includes at least one set of jacks, and each set of jacks is composed of L holes, N holes, and E holes.
[0030] In this embodiment, the trigger switch is specifically a tact switch SW1 (which can also be replaced by a shrapnel), which is located at the bottom of the E hole. When the plug is fully inserted into the socket, the PE pin of the plug presses down the button of the tact switch SW1 to close the tact switch SW1. One end of the light touch switch SW1 is connected to the ground wire PE, and the other end is connected to the high level port of the controller.
[0031] The controller MCU has a high level port P0, an output port I / O and a current detection port ADC. In addition to being connected to the tact s...
Embodiment 2
[0041] Such as image 3 and Figure 4 , the method for controlling the electric vehicle charging cover proposed in this embodiment can be realized through the electric vehicle charging socket proposed in Embodiment 1, and is the flow of the program stored and executed by the controller MCU and executed by the radio frequency communication module.
[0042] This embodiment includes the following steps:
[0043] a) Obtain the status information of the charging socket.
[0044] The status information of the charging socket includes: a level signal indicating whether the power plug of the charging gun is inserted into the charging socket or not. In this embodiment, the action of inserting the power plug of the charging gun into the charging socket triggers the change of the level signal, so that the controller can obtain the status information of the charging socket.
[0045]When the power plug of the charging gun is not inserted into the charging socket, the tact switch SW1 is ...
