A new kind of charger that allows an electric vehicle (EV) to be used as a giant home battery is close to going on sale in Australia, with the first commercial shipment to arrive within weeks.
Unlike standard one-way EV chargers, bidirectional chargers can also discharge energy from an EV, which means they can be used to power a home (known as vehicle-to-home or V2H) and its appliances, or to export energy to the grid (vehicle-to-grid or V2G).
This may sound simple, but bringing them to Australia has proven difficult.
For years, a mix of regulatory and engineering hurdles have repeatedly pushed back the technology’s rollout date.
