What is bidirectional charging (V2L, V2H, V2G) and which Chinese EVs support it?
Bidirectional charging turns the car into a mobile power source. Here's what each acronym means and which models actually deliver.
Three tiers
V2L: 3-pin/CEE-form socket in the car. Power camping gear, tools, an e-bike charger.
V2H: The car powers your house via a bidirectional wallbox — useful during outages.
V2G: The car sells power to the grid when prices are high.
Chinese EV support
V2L standard on: BYD Atto 3/Dolphin/Seal/Han, Xpeng G6/G9, Zeekr 001/7X, Aito M9.
V2H available on: BYD Atto 3 (via BYD wallbox in UK); NIO ET5/ET7 (planned via NIO Power).
V2G pilots: BYD in Germany with EWE; Xpeng in the Netherlands.
Real utility
3 kW V2L covers most camping and DIY use cases.
V2H saves ~£200–400/year via time-shifting cheap overnight electricity to daytime use.
- 01V2L is universal on new Chinese EVs.
- 02V2H is available today on BYD; expanding across brands.
- 03V2G remains pilot-scale but growing.
