Bidirectional charging enables electric vehicles (EVs) to not only draw power from the grid but also supply electricity back to it or power external devices. This functionality is categorized into:
- Vehicle-to-Load (V2L): Powers external devices directly from the vehicle.
- Vehicle-to-Home (V2H): Supplies power to a home or building.
- Vehicle-to-Grid (V2G): Sends electricity back to the grid to support energy demands.
Several EV models available in Australia come equipped with bidirectional charging capabilities:
- MG ZS EV: Offers V2L functionality with a maximum load of 2.2 kW.
- MG4: Features V2L with a 2.2 kW load capacity.
- BYD Atto 3: Provides V2L, supporting up to 3.6 kW, though the included adapter is rated at 2.2 kW.
- BYD Dolphin: Equipped with V2L capabilities.
- Hyundai Ioniq 5: Supports V2L.
- Kia EV6: Includes V2L functionality.
- Kia EV9: Offers V2L, V2H, and V2G capabilities.
- Nissan Leaf: Supports V2H and V2G.
- Mitsubishi Outlander PHEV: Features V2G, V2H, and V2L.
It’s important to note that while V2L is commonly available, V2H and V2G functionalities may require additional equipment and are subject to local regulations. For instance, in Australia, the Wallbox Quasar is the only bidirectional charger approved for V2G use, and its compatibility is currently limited to the Nissan Leaf.
As the EV market evolves, more manufacturers are expected to incorporate bidirectional charging features into their vehicles, enhancing their utility and integration with energy systems.
