Benefits of technology
This patent describes a method and apparatus for ensuring security in an EV wireless power transfer system. The invention verifies the identity of the vehicle's controller before starting the charging process, preventing unauthorized charging or theft of private information. Additionally, an authentication apparatus can be used to further prevent abuse of the controller, reducing the risk of theft and abuse of the charging system. Overall, this technology enhances the reliability and stability of the vehicle's controller and prevents unscrupulous individuals from abusing the charging system.
Problems solved by technology
Meanwhile, theft or loss of a controller in the vehicle, access by unauthorized persons, or abuse of the controller in the aftermarket may result in cases in which the controller of a specific user can be used in other cars.
However, even when an in-vehicle controller is authenticated before starting a charging process between an EV and an external charger, it is impossible to identify a case in which a stolen controller is installed in a different car.
Also, the method may further comprise, after the authenticating, blocking the charging process when the authentication is determined as failed.

A security method and apparatus for an electric vehicle (EV) power transfer system can prevent abuse of privacy information or financial information which is stored in an in-vehicle controller, and block fee charging and authentication. A security method for the EV power transfer system, performed by a charging controller installed in an EV, includes steps of: receiving an authentication request from a communication controller installed in the EV; authenticating second key information included in the authentication request based on first key information which is learned or stored beforehand; and when the authentication succeeds, starting a charging process.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims under 35 U.S.C. §119(a) the benefit of Korean Patent Application No. 2015-0145922 filed on Oct. 20, 2015 in the Korean Intellectual Property Office (KIPO), the entire contents of which are incorporated by reference herein.BACKGROUND1. Technical Field[0002]The present disclosure relates to security technology for a vehicle, and more particularly, to a security method and apparatus for an electric vehicle (EV) power transfer system, which can prevent charging and authentication of an EV by unauthorized persons, thus protecting privacy information and financial information stored in a controller installed in the EV.2. Description of the Related Art[0003]Various tasks are undertaken for preparing charging and authentication in a next-generation vehicle charging system used for environment-friendly vehicles such as electric vehicles (EV), plug-in EVs, and plug-in hybrid EVs. With regard to an EV charging system, there is...
