Description

A plug-and-charge system and method of use based on an intelligent charging gun

technical field

The invention belongs to the field of intelligent charging, and in particular relates to a plug-and-charge system based on an intelligent charging gun and a method for using the same.

Background technique

At present, the charging methods in the industry mainly include swiping cards, scanning codes, entering account numbers, and plug-and-charge based on vehicle VIN (only DC charging piles are available), etc. Except for the plug-and-charge method based on vehicle VIN, other charging methods require users Provide identity information to the charging pile for authentication before each charging, and take corresponding actions to confirm the payment at the end of charging. Users generally think that the charging process is cumbersome, and they expect the charging device to have the plug-and-charge function. However, the plug-and-charge method based on the vehicle VIN requires vehicle manufacturers to cooperate with the VIN. At present, only a small number of vehicle companies have released this information.

The interface between the existing charging equipment and the vehicle complies with the requirements of the national standard, and has been unified. The physical interface, electrical performance and communication protocol all meet the requirements of the national standard, but the charging connection device does not have the functions of authentication and settlement. As shown in Figure 2, before charging is turned on, the user initiates authentication by swiping a card on the charging device or scanning the QR code of the charging device with a mobile phone. During settlement, the user starts the settlement process after confirming the transaction information, or automatically settles after the user enables password-free payment. Swiping a card, entering an account number or scanning a code to charge, turning on the charging during charging, and charging settlement all require user participation. The process is more complicated, and the user needs to learn and adapt to the charging operation steps, which brings inconvenience to the user. In this solution, the charging process is cumbersome, and user operations are required to initiate authentication and start charging. To charge by swiping a card, you need to apply for a physical card and carry it with you, and enter a password for authentication before charging, which brings extra burden to the user; while charging by entering an account requires the user to enter the account number and password on the charging pile, and the user operation takes a long time. Moreover, due to the large number of account digits, there is a risk of input errors and need to be input repeatedly; scanning code charging requires users to open the mobile APP before charging each time. When the QR code is not clear in strong sunlight, it is more common to fail to scan the code. .

The invention realizes plug-and-charge, and does not require the vehicle to provide VIN, simplifies the user's charging operation process, and improves the user's charging experience.

On the basis of the existing national standard charging interface, the present invention transforms the charging gun and the socket 9 of the electric vehicle (both the socket and the charging socket of the electric vehicle refer to the socket 9).

As shown in FIG. 5 , the hardware tag 10 is composed of a coil and a chip, and is installed on the charging socket 9 at the end of the vehicle to store the user information of the electric vehicle and the identification of the vehicle. The hardware tag 10 is a radio frequency electronic tag, which complies with the relevant requirements of ISO14443.
