Embodiment 1

[0060] figure 1 Middle is a schematic diagram of the architecture of the wireless charging access authentication system of this embodiment. As shown, including:

[0061] The on-board charging device 101, such as the on-board charging device on an electric vehicle, may include a battery pack, a charging module, a control module, a wireless communication module and a display module. The on-vehicle charging device in this embodiment has a globally unique device identifier, which can be assigned by the device manufacturer when the device leaves the factory, and is fixed for life. Authentication data may also be stored in the on-board charging device, such as including a pre-configured certificate issued by the authentication center 105 .

[0062] User card 102, the user card is used to uniquely identify the identity of the user, and contains identity information of the user, including user ID and the like. Authentication data is also stored in the user identification card, such...

Embodiment 2

[0110] The process of this embodiment is basically the same as that of Embodiment 1, the difference is that only the one-way authentication of the user by the device manager is performed, and the on-board charging device does not authenticate the device manager.

[0111] The specific differences in the process are reflected in:

[0112] In step 205, the authentication request sent by the on-board charging device to the wireless charging pile is information that carries a request for a certificate from the device manager;

[0113] In step 208, the authentication success response sent by the device manager to the wireless charging pile does not carry the device manager certificate;

[0114] In step 210, the on-board charging device does not verify the device manager certificate.

[0115] Further, the mutual authentication between the device manager and the on-board charging device can also be simplified as a one-way authentication of the device manager on the on-board charging ...

Embodiment 3

[0117] The flow of this embodiment is basically the same as that of Embodiment 1, the difference is that the certificate of the on-board charging device is not preset, but downloaded from the CA during the authentication process.

[0118] The specific differences in the process are reflected in:

[0119] In step 201, the on-board charging device does not pre-configure the certificate;

[0120] In step 208, the authentication success response sent by the device manager to the wireless charging pile does not carry the device manager certificate;

[0121] In step 201, the on-board charging device does not verify the device manager certificate.

[0122] Between steps 203 and 204, the following step is added: the on-board charging device downloads the certificate. The on-board charging device can download the certificate from the CA, or download the certificate from other network elements related to certificate management.

Abstract

An authentication method for a vehicle-mounted charging device and a corresponding device, which are applied to the authentication when a vehicle-mounted charging device which is provided with a user card accesses a charging station serving network. The method comprises: reading, by a vehicle-mounted charging device, a user identity identifier and a user certificate from a user card; establishing a wireless link with a wireless charging pile, sending an authentication request to a device manager through the wireless charging pile, and carrying the user identity identifier, the user certificate and device information about the vehicle-mounted charging device; and after the authentication of the device manager of a serving network of the user identity identifier, the user certificate and the device information about the vehicle-mounted charging device, and after it is judged that the vehicle-mounted charging device matches the wireless charging pile, returning an authentication success response. The solution can effectively improve the security of wireless charging, reduce the accident rate and prevent electricity theft.

Description

technical field [0001] The invention relates to wireless charging technology, in particular to an authentication method and corresponding equipment for on-board charging equipment in an electric vehicle to a charging station service network. Background technique [0002] The ever-increasing number of cars puts forward a high demand for oil and natural gas-based energy sources, while petrochemical energy sources are increasingly depleted, and oil prices will remain high in the long run. At the same time, the air pollution caused by vehicle exhaust is becoming more and more serious. [0003] Electric vehicles are powered by on-board power supplies, and use motors to drive wheels. Due to the advantages of energy saving, environmental protection and low noise, electric vehicles are widely optimistic about their prospects. However, the development of electric vehicles still faces many technical problems, and the development of charging technology and the deployment of charging ...
