Would you consider an electric car that could power your home during an outage?
Audi detailed bidirectional charging functions for the A2 E-Tron on November 12, 2026, confirming the vehicle supports bidirectional charging. Vehicle-to-Load lets the car power external devices directly, while Vehicle-to-Home feeds stored battery energy into the house.
Why it matters
Bidirectional charging could let owners use an electric vehicle's battery as backup power for household devices, reducing reliance on the grid at certain times. Vehicle-to-Grid, which would return energy to the power network, is not yet live.
The A2 E-Tron ships with 52-kWh, 61-kWh and 84-kWh packs, with DC fast charging of 100 to 183 kW and a 24-minute 10-to-80 percent top-up on the 52-kWh pack. Vehicle-to-Home operates within a 20 to 80 percent state-of-charge window.
The players
Audi
Audi is a German luxury automaker and a subsidiary of the Volkswagen Group, known for its electric vehicle lineup.
The details
Vehicle-to-Home requires a compatible bidirectional DC wallbox and draws on the battery between 20 and 80 percent state of charge. The 52-kWh and 61-kWh packs use lithium iron phosphate chemistry, while the 84-kWh pack uses nickel-manganese-cobalt.

Roadmap
Audi's bidirectional charging extends the vehicle-to-grid concept beyond flagship models, with the company expecting Vehicle-to-Home to spread across its lineup rather than stay reserved for top trims. The move reflects a broader industry push to turn electric vehicles into mobile energy storage.
Owners who add a compatible bidirectional DC wallbox could power household devices during outages or peak-price periods. Buyers should confirm wallbox compatibility and charging limits before relying on Vehicle-to-Home.
The takeaway
Bidirectional charging turns an electric car into a potential home battery, but buyers should check wallbox compatibility and the 20 to 80 percent operating window before counting on it for backup power.
