[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present application are described in detail below with the help of drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0021] like Figure 1 As shown, a new energy vehicle charging wake-up control system includes a charging control circuit 8 and a relay detection circuit 2;

[0022] One end of the charging control circuit 8 is grounded, and the other end is connected to the charging interface 1. The charging control circuit 8 includes a first charging circuit 81 and a second charging circuit 82 arranged in parallel;

[0023] One end of the relay detection circuit 2 is connected to the power supply, and the other end is connected to the vehicle controller 7. The relay detection circuit 2 includes a first detection circuit 21 and a second detection circuit 22 arranged in parallel;

[0024] A 24V relay 6 is installed between the first charging circuit 81 and the first detection circuit 21 , and a 12V relay 3 is installed between the second charging circuit 82 and the second detection circuit 22 .

[0025] In some embodiments, a meter 5 connected to the relay detection circuit 2 is further included. The vehicle controller 7 is connected to the meter 5 via a CAN bus, and the charging status information can be displayed via the meter 5.

[0026] In some embodiments, a VTS tube 4 connected in parallel with the 12V relay 3 is further installed on the second charging circuit. The VTS tube 4 mainly plays a protective role. When the voltage exceeds a set value, it opens to prevent the 12V relay 3 from being damaged by high voltage shock.

[0027] In some embodiments, the VTS tube 4, 12V relay 3 and 24V relay 6 are respectively arranged in the middle position of the cab guard plate, the vehicle controller 7 is arranged on the left side of the cab guard plate, the instrument 5 is arranged on the upper position of the cab guard plate, and the relay detection circuit 2 is arranged at the chassis charging port position. It is low-cost and easy to install, and is arranged in the cab to prevent line failure caused by rain, etc.

[0028] A second aspect of the present invention further provides a vehicle, on which the new energy vehicle charging wake-up control system is installed.

[0029] The specific steps include:

[0030] Step 1: Hard wire transfer:

[0031] The 12V relay 3, the 24V relay 6 and the instrument 5 are controlled by hard wires, the 12V relay 3, the 24V relay 6 and the vehicle controller 7 are controlled by hard wires, the 12V relay 3, the 24V relay 6 and the relay detection circuit 2 and the VTS tube 4 are controlled by hard wires; the vehicle controller 7 receives relay signals through a hard wire harness, the relay detection circuit 2 detects the relay status through hard wires, and the instrument 5 receives relay signals through a hard wire harness;

[0032] Bus transmission: The vehicle controller 7 and the instrument 5 transmit information via the CAN bus;

[0033] Step 2: Drive the actuator:

[0034] When the charging gun is plugged in, the A+ power supply on the charging gun will be transmitted to the relay detection circuit 2 through a hard wire, and then transmitted to the 12V relay 3 or 24V relay 6 through the relay detection circuit 2, causing the relay to be energized. After the relay is energized, the signal is transmitted to the vehicle controller 7 and the instrument 5. The vehicle controller 7 executes the charging instruction and sends the charging status information to the instrument 5, which is displayed on the instrument 5.

[0035] This new system adds a relay detection circuit, a 24V relay and a 12V relay, and a VTS tube at the front end of the 12V relay. The two relays are connected in parallel. During vehicle charging, both the 12V and 24V charging stations can drive the corresponding relays, waking up the electrical components involved and completing the charging of the vehicle's high-voltage battery pack. This new system increases charging reliability and user convenience, providing an effective method for waking up new energy vehicles.

It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations, improvements or equivalent substitutions can be made, all of which should be included in the scope of the claims of the present invention.
