Question

What specific communication standard defines the digital handshake between an EVSE and the vehicle&#x27;s onboard controller to enable plug-and-charge capabilities and bi-directional power flow?

Accepted Answer

The communication standard that defines the digital handshake between an electric vehicle supply equipment and a vehicle&#x27;s onboard controller for plug-and-charge and bi-directional power flow is ISO 15118. This international standard governs vehicle-to-grid communication, allowing the car and the charger to exchange information digitally over the charging cable. The digital handshake is a process where the two devices perform a mutual authentication and authorization check to verify the vehicle&#x27;s identity and payment credentials, which enables the plug-and-charge feature where charging begins automatically upon connection without needing a separate card or app. ISO 15118-2 defines the initial requirements for this communication, while ISO 15118-20 is the updated version that specifically adds support for bi-directional power transfer, which allows the vehicle to not only draw electricity from the grid but also send stored energy back to the grid or a home when needed.
