Electrical Design of V2G - System Architecture

• DC V2G is already possible via the CHAdeMO protocol however CCS will not support V2G until 2025, and AC V2G is expected to be more widespread in the near future.
• Placing the power electronics in the EVSE, where increased size and weight are less of a problem, could allow higher power DC V2G to take place which may be useful in some situations.
• Lower cost AC V2G charging infrastructure could lead to more widespread deployment at longer dwell time locations that are more suitable for V2G.
