The ISO 15118 or better known as vehicle-to-grid standard, is something that we are working on. Since 2018 we have envisioned and hoped that the adoption of this standard would become a reality and took the chance on implementing the hardware.
Currently the number of cars that support this are minimal, but it looks like car manufacturers are starting to adopt this for AC charging as well. We have done some initial testing on the cars that have been available.
Both hardware and firmware still need further work and testing to ensure we can support ISO 15118. Right now, we can say we are hopeful that we can support ISO 15118 in the near future.
