And S402, if the vehicle authentication result is that the vehicle authentication result is not passed, controlling the charging pile to output a charging CP signal with the duty ratio of 100%.

Specifically, in some embodiments of the present invention, if the vehicle authentication result obtained according to the second CP signal fed back by the vehicle is failed, the charging pile controller may control the charging pile to output the PWM signal with the duty ratio of 100%, so as to prohibit the charging pile from providing the charging service for the vehicle.

Optionally, after the charging pile controller controls the charging pile to output a PWM signal with a duty ratio of 100%, the charging pile can be controlled to send prompt information to a user to prompt that vehicle authentication fails, and the user can be advised to send a preset vehicle identification code to the charging pile to open a related charging service, so that a charging pile service object can be expanded, the user does not need to continuously drive the vehicle to search for other charging piles, user operation is reduced, and user experience of vehicle charging is optimized.

Further, as shown in fig. 5, acquiring an authentication result of the vehicle according to the second CP signal includes:

Specifically, the second CP signal is a clock pulse signal, and the vehicle identification code is a 17-bit character, so in some embodiments of the present invention, the second CP signal corresponding to the vehicle identification code may be generated by the vehicle according to a preset encoding rule, and further, after the charging pile controller receives the second CP signal through the CP port of the charging pile, the second CP signal may be analyzed by using the preset encoding rule, so as to obtain the vehicle identification code corresponding to the second CP signal, so as to perform vehicle authentication.

The preset encoding rules are described and illustrated in tables 1 to 4 and the specific embodiments of the present invention.

TABLE 4

For example, assuming that the charging pile is only open for the polar fox authentication vehicle, the vehicle may convert a vehicle identification code composed of 17-bit characters into 17-bit numbers according to the national standard GB16735-2019, further calculate a weighted sum of the 17-bit numbers in combination with the weighting coefficient, generate a second CP signal corresponding to the polar fox authentication vehicle according to the weighted sum, further feed the second CP back to the charging pile, analyze the second CP signal according to the preset encoding rule, and reversely derive a vehicle identification code corresponding to the second CP signal to perform vehicle authentication of the polar fox authentication vehicle, where the weighting coefficient is not specifically limited in this embodiment, and may be correspondingly calibrated according to the type of the vehicle.

Specifically, taking table 4 as an example, assuming that the current vehicle is an polar fox authentication vehicle, and the vehicle VIN code is LFWADRJF111002345, based on the correspondence relationship between the above tables 1 to 3, the 17-bit value corresponding to the vehicle VIN code is 36614916111002346, and a weighted sum value 275 of the 17-bit value can be obtained by combining with a weighting coefficient, and then a second CP signal corresponding to the vehicle VIN code (LFWADRJF 111002345) is generated according to the weighted sum value 275, so that after the charging pile controller receives the second CP signal through the CP port of the charging pile, the second CP signal can be analyzed by using a preset encoding rule, and thus the vehicle identification code corresponding to the second CP signal is wadrjf111002345, and the vehicle is determined to be the polar fox authentication vehicle.

Further, assuming that the charging pile is only open to the north automobile, at this time, because the first 3-bit character of the vehicle identification code of the north automobile is a fixed character LNB, the first 3-bit character of the vehicle identification code can be converted into a 3-bit number according to the national standard GB16735-2019 according to a preset encoding rule, and a second CP signal corresponding to the north automobile is generated according to the 3-bit number, and then the second CP is fed back to the charging pile, and the charging pile analyzes the second CP signal according to the preset encoding rule, so that the first three-bit character of the vehicle identification code corresponding to the second CP signal is obtained as the LNB, and the vehicle is determined to be the north automobile.

Further, suppose that charging pile is open to all vehicles, at this moment, the vehicle authentication is no longer performed to the vehicles, and the user can directly use the charging function of charging pile.

And S502, judging whether the vehicle identification code is consistent with a preset vehicle identification code.

Specifically, in some embodiments of the present invention, since the vehicle identification code of each vehicle is unique, the charging pile controller may determine whether the vehicle has the right to use the charging pile by determining whether the vehicle identification code received by the CP port of the charging pile is consistent with a preset vehicle identification code that is bound by a user in advance.

S5031, if the vehicle identification code is consistent with the preset vehicle identification code, determining that the authentication result of the vehicle is passed.

Specifically, in some embodiments of the present invention, if a preset vehicle identification code that is consistent with a vehicle identification code corresponding to the second CP signal exists in all the preset vehicle identification codes stored in the charging pile, it is determined that the authentication result of the vehicle is passed, and at this time, the vehicle has the authority to use the charging pile, and the charging pile is allowed to perform a charging service for the vehicle.

S5032, if the vehicle identification code is not identical to the preset vehicle identification code, determining that the authentication result of the vehicle is failed.

Specifically, in some embodiments of the present invention, if there is no preset vehicle identification code that is consistent with the vehicle identification code corresponding to the second CP signal among all the preset vehicle identification codes stored in the charging pile, it is determined that the authentication result of the vehicle is failed, and at this time, the vehicle does not have the right to use the charging pile, and the charging pile is prohibited from performing charging service on the vehicle.

Further, the method further comprises: and acquiring and storing the preset vehicle identification code transmitted by the mobile terminal.

Specifically, in some embodiments of the present invention, a user may establish a communication relationship with a charging pile through a mobile terminal based on a 4G, 5G, or bluetooth protocol, and then send a preset vehicle identification code to the charging pile through the mobile terminal, so that the charging pile stores the preset vehicle identification code, thereby establishing a binding relationship between a vehicle corresponding to the preset vehicle identification code and the charging pile.

Further, the method further comprises the step of re-receiving a second CP signal fed back by the vehicle if the charging pile does not output the charging CP signal with the duty ratio of the first duty ratio within a second preset time, and acquiring an authentication result of the vehicle according to the second CP signal.

Specifically, in some embodiments of the present invention, when the vehicle authentication result is a pass, the charging pile controller may output a charging CP signal with a duty ratio of a first duty ratio through a CP port of the charging pile to provide a charging service for the vehicle, and if the charging pile does not output the charging CP signal with the duty ratio of the first duty ratio within a second preset time, the charging pile may determine that the charging pile does not meet the vehicle charging requirement, at this time, the vehicle may feed back a second CP signal to the charging pile again, and the charging pile controller may receive the second CP signal fed back by the vehicle again through the CP port of the charging pile and obtain the authentication result of the vehicle according to the second CP signal, where the second preset time is not specifically limited in this embodiment, and for example, the second preset time may be 3 seconds.

Optionally, in some embodiments of the present invention, if the charging post does not output the charging CP signal with the first duty ratio within 3 seconds, the charging post may receive the second CP signal fed back by the vehicle again, and when the charging post still does not output the charging CP signal with the first duty ratio within 3 seconds, the vehicle will not send the second CP signal again.

Referring to fig. 6 and a specific embodiment of the present invention, specific process steps of the charging control method are described below, and as shown in fig. 6, after the charging pile establishes a charging connection with the vehicle, step S1 is executed:
