The vehicle battery SOC is missing on iso15118-2 AC charging.

Is there a way or option to send the vehicle battery SOC?

Hi @coollhc77, unfortunately in AC charging, the ISO 15118-2 does not foresee an option for the EV to send its SoC or battery capacity. The only EV data you get is the one during the charge parameter Discovery:

Unfortunately, this means that if you need that data, you need to get it externally, like via the EV telematics API

Thanks for your detailed explanation.
