Plug & Charge is enabled by ISO 15118, the international standard for charging electric vehicle. When using Plug & Charge, you don't need to use additional cards, apps or manual authentication steps. Instead, you can just connect the charging cable to your vehicle, which automatically recognizes and authenticates your vehicle, allowing the charging process to start.
The number of charging stations that support Plug & Charge is limited, and not all types of charging might be supported. If the charging station doesn't support Plug & Charge, you need to authorize yourself at the charger.
There are other ways that can help you simplify your charging process. By using your vehicle's VIN number or MAC address, you can connect the information to different apps and charging providers. Your vehicle can then be automatically identified at the charging station, without any need for additional cards. However, the vehicle displays won't show any information or instructions for these methods.
