What is Electric Vehicle Plug & Charge?
Plug & Charge is the simplest, most secure way for drivers to charge their electric vehicles. All drivers need to do is connect their EV’s charging cable to the charge point, and the vehicle is automatically charged. Plug and charge falls under ISO 15118, the international standard for charging electric vehicles, which is focused on securing the future of vehicle charging through simplicity of use.
Why should EV owners care about Plug & Charge?
EV owners should care about Plug & Charge because it streamlines the EV charging experience. Instead of having to use a credit card, present an RFID tag, using a mobile app, all they need to do is connect their vehicle to the charge point – via cable for AC and DC charging vehicles or Wi-Fi for wireless charging.
During a Plug & Charge session, security is paramount. The transaction, information about the vehicle and owner, the billing details, and the charging network all need to be protected from third-party manipulation. ISO 15118’s standards ensure this happens with encryption, decryption, and two-way authentication.
Plug & Charge uses a variety of cryptographic tools to secure communications between the vehicle and the charging infrastructure, protecting the driver’s personal information, the vehicle’s systems that are “touched” during the charging process, and the charging infrastructure – from malicious third-party actors during the charging process. Once the vehicle-charge point connection is made, all identification and authorization happen across a highly secure communications link, to ensure data is exchanged in a confidential and authenticated way.
Each vehicle is linked to an individual billing account, whether personal, family, corporate, or other EV owner. Authentication standards allow the EV to automatically identify itself to the charging network and have the backend system “issue” validation, and then begin the charge. The transaction will be accurately documented to reflect the energy that was supplied to the EV.
With complying with ISO 15118 and Plug & Charge, eMobility service providers ensure drivers enjoy a more convenient and secure charging experience, while streamlining EV charging operations.
