What impact does ISO15118-20 have on the AC EV Charger Manufacturers? Especially V2G


European AC EV Charger Manufacturers Should Keep an Eye on the ISO 15118 Update

If your company is developing or exporting AC EV chargers to Europe, the ISO

15118 series is a standard you should keep an eye on. It defines how EVs and charging stations communicate during charging and plays an important role in features such as Plug & Charge and smart charging.

For today's European AC charging market, ISO 15118-2 remains an important reference for communication between EVs and charging stations. With this standard, chargers can exchange charging parameters and status information with vehicles, enabling Plug & Charge and providing a foundation for smarter charging management.

At the same time, ISO 15118-20 is the next-generation standard, bringing support for bidirectional charging and Vehicle-to-Grid (V2G) applications. For manufacturers, this means current products need to maintain stable ISO15118-2 compatibility, while the hardware platform should also leave room for future upgrades to ISO 15118-20.

For AC charging projects in Europe, protocol support is no longer just a technical detail-it is becoming part of the product strategy. Getting ISO15118-2 compatibility right today, while preparing for ISO 15118-20, can help manufacturers stay ready for evolving market requirements.
