V2G Australia: Vehicle-to-Grid Charging Explained (2026)

Vehicle-to-grid charging is the idea that an EV’s battery - 60 to 100kWh of storage sitting idle most of the day - can do more than transport people. By discharging power back into the electricity grid during peak demand, V2G turns your car into a revenue-generating asset. You charge cheaply overnight. You export during the 5pm peak when grid power is expensive. The grid gets flexible storage. You get money back.

The concept has been discussed in Australia for years. In 2026, it’s becoming real. The regulatory framework was established in late 2024. Pilot programs have run in the ACT, SA, and Queensland. A small but growing number of vehicles and chargers support the required bidirectional charging technology. This guide covers what V2G actually is, how it differs from V2H and V2L, which products support it in Australia, and whether the economics justify the investment.

V2L, V2H, and V2G: the difference matters

Before getting into V2G specifics, the three bidirectional technologies need to be separated. They’re commonly confused, and the differences determine what’s actually possible with your car.

V2L (Vehicle-to-Load) is the most basic. Your car has a built-in AC outlet - typically in the boot or under the rear bumper - and you can plug appliances directly into it. A camping fridge, a laptop, power tools, or an emergency lamp. It usually delivers 2.2–3.6kW. No home installation required. It’s available today on the Hyundai IONIQ 5, IONIQ 6, Kia EV6, Kia EV9, MG MG4, BYD Seal, Atto 3, and Sealion 7, among others.

V2H (Vehicle-to-Home) is a step up. A bidirectional charger installed on your wall can reverse the flow of power: instead of charging the car, it draws from the car battery and feeds your home’s circuits. During a blackout or high-price period, your house runs off the EV rather than the grid. It requires a specific bidirectional charger unit at home and a compatible car. The car doesn’t need to communicate with the grid - it just powers the house.

V2G (Vehicle-to-Grid) is the most complex. The car can export power all the way back to the electricity network, not just your home. Your DNSP (distribution network service provider) and energy retailer must approve the export, the charger must be certified for grid export, and the car must support the necessary bidirectional charging standard. In exchange, you can receive export income, participate in demand response programs, or access managed-rate contracts that pay more for your exports during peak periods.

Most EVs with V2L do not support V2H or V2G. The hardware and software requirements are substantially different.

How V2G works technically

Standard EV charging converts AC from the grid to DC for the battery. V2G adds a bidirectional inverter that can run the conversion in reverse: DC from the battery becomes AC that can feed the home or the grid.

For grid export specifically, the charger must be capable of forming a stable AC output that meets grid quality standards (voltage, frequency, phase angle). It must also include automatic disconnection - if the grid goes down, the charger must isolate immediately to protect electricity workers on the lines. This anti-islanding requirement is the same standard that governs solar inverters under AS/NZS 4777.

The car side requires the vehicle to support bidirectional DC charging through its charge port. The two standards relevant to Australia are CHAdeMO and CCS2:

• CHAdeMO (Nissan Leaf, Mitsubishi Outlander PHEV) has supported bidirectional charging since around 2013. The infrastructure for CHAdeMO V2G is mature. However, CHAdeMO is being phased out of new vehicles globally - new EVs use CCS2.
• CCS2 bidirectional (ISO 15118-20) is newer and more capable. It supports grid-managed charging, automated scheduling, and smart tariff integration. The Kia EV9 Earth AWD and Hyundai IONIQ 5 with updated firmware support this standard. CCS2 bidirectional infrastructure is expanding but less widespread than CHAdeMO.

Which EVs support V2G in Australia?

Not many - but the list is growing.

Nissan Leaf (40kWh, 62kWh) - The most established V2G vehicle in Australia. CHAdeMO port supports bidirectional charging with compatible chargers. The Leaf has been used in Australian V2G pilot programs for several years. Older 40kWh models have limited range, but the 62kWh e+ variant is a capable daily driver. Note: CHAdeMO is no longer offered on new vehicles. The Leaf’s successor, the Nissan Ariya, does not support V2G yet in Australia.

Mitsubishi Outlander PHEV - The plug-in hybrid has a CHAdeMO port and supports V2H/V2G with compatible equipment. The battery is smaller (13.8kWh usable) than a full BEV, but the petrol engine provides unlimited driving range. The Outlander PHEV has been used in the SA Power Networks V2G pilot.

Kia EV9 Earth AWD - The most capable new V2G vehicle available in Australia. CCS2 bidirectional support, 99.8kWh battery, and compatibility with Wallbox Quasar 2 and other CCS2 bidirectional chargers. A very large amount of grid storage per vehicle. The EV9 Earth AWD starts at around $109,000.

Hyundai IONIQ 5 (bidirectional firmware) - The IONIQ 5 has the hardware for CCS2 bidirectional charging. Hyundai has been rolling out V2G-enabling firmware updates. Compatibility depends on the specific build date and firmware version. Check with your dealer and a compatible charger supplier for current status.

BYD (upcoming) - BYD has confirmed V2G support for future models. No specific Australian launch date confirmed as of April 2026.

Most other EVs - Tesla Model 3 and Y, BYD Atto 3, Seal, MG4, Volvo EX30, BMW iX, and most other EVs currently sold in Australia support V2L only. They cannot feed power back to the home or grid.

V2G chargers available in Australia

A compatible car is only half the requirement. You also need a bidirectional charger that is approved for Australian grid export.

Wallbox Quasar 2 - The Quasar 2 is a CCS2 bidirectional charger that supports V2G export. It’s compatible with the Kia EV9 Earth AWD and IONIQ 5 (with firmware). Wallbox has been one of the primary equipment suppliers in Australian V2G pilot programs. Price is around $4,500–$6,000 installed.

EVSE Australia Bidirectional (CHAdeMO) - Specialist V2G chargers for CHAdeMO vehicles including the Nissan Leaf. These are CHAdeMO-specific and not compatible with CCS2 vehicles.

Switching to CCS2 - As CHAdeMO is phased out of new vehicles, the industry is shifting to CCS2 bidirectional. New installations now predominantly use CCS2 chargers.

Australian V2G programs and pilots

V2G in Australia has moved from research to commercial operation, though programs remain limited in geographic scope.

ActewAGL / AGL Smart Home - ACT residents with compatible vehicles and Wallbox Quasar 2 chargers can participate in managed export programs. The program pays above feed-in tariff rates for EV export during peak demand windows. Early participants have reported net annual benefits of $800–$1,800 depending on driving patterns and grid response activity.

SA Power Networks - SAPN ran a V2G trial with CHAdeMO vehicles in South Australia. The program demonstrated grid stability benefits from aggregated EV storage across 50 vehicles. Commercial expansion is planned for 2026–27.

Evoenergy (ACT) - The ACT distribution network has approved V2G export for compliant charger installations. Participants need an Evoenergy-approved installer and a compliant charger.

Virtual Power Plant integration - Several Australian VPP operators (AGL, Energy Locals, and others) are exploring V2G-capable EV integration into their existing rooftop solar and battery VPP programs. An EV with V2G capability enrolled in a VPP can receive dispatch signals during high-demand events, dispatching car battery power in the same way a Powerwall would.

The economics: does V2G pay?

The V2G value proposition depends on several factors working together. Here’s a realistic breakdown.

The costs:

• Bidirectional charger (Wallbox Quasar 2 installed): ~$5,000–$7,000
• Electrician upgrade if board work needed: $500–$1,500
• Compatible EV premium: the Kia EV9 Earth AWD costs ~$109,000 - a premium over non-V2G alternatives

The benefits:

• Export income during peak periods: variable, but peak wholesale prices regularly hit 50–100 cents/kWh in evening peaks
• Avoided import cost: shifting from peak imports (~45 cents/kWh on residential ToU) to off-peak charging (~15 cents/kWh overnight) saves ~30 cents/kWh cycled
• Demand response payments: some programs pay additional fees for dispatchable capacity, independent of energy volume

A worked example: Assume 20kWh exported per week during peak periods at an effective 50 cents/kWh benefit (export income plus avoided import). That’s $10/week, $520/year. Over five years: $2,600.

Against a $6,000 charger cost, that’s a 11-year simple payback from energy arbitrage alone. That math doesn’t work on its own.

Where V2G improves financially:

• A household with solar panels (reducing daytime import, increasing self-consumption value)
• Participation in a VPP with demand response payments on top of energy arbitrage
• Using the bidirectional charger as a home battery backup (V2H value stacked on top of V2G)
• Rising electricity prices over the analysis period (likely, given historical Australian tariff trends)

For most households in 2026, V2G is not primarily a financial investment. It’s more compelling as a whole-home resilience solution - the V2H capability (blackout backup) and V2G together, with the financial return as a bonus rather than the primary driver.

V2G vs. home battery: how to choose

If your goal is home energy storage and backup, the comparison is between V2G-capable EV setup and a standalone home battery.

	V2G (EV + bidirectional charger)	Home battery (e.g. BYD HVM 11kWh)
Storage capacity	60–100kWh (full EV battery)	11–16kWh typical
Usable backup	40–80kWh (with cycle limits)	9–14kWh
Charger cost	$5,000–$7,000	Included in battery
Battery cost	Included in EV	$8,000–$14,000 installed
V2G income	Yes	No
Always available	No (car may be out)	Yes
Warranty coverage	EV warranty may not cover V2G cycles	Typically 10 years

The EV’s storage advantage is enormous - 60kWh versus 11kWh. But availability is the key risk: if the car is out for a day trip when a blackout hits, you have no backup. Households that use V2H/V2G successfully often have relatively predictable parking patterns (car home most evenings, not frequently away overnight).

Is V2G worth it in Australia right now?

For most households: not yet, if the primary motivation is financial return.

For specific situations, yes:

• You own a Nissan Leaf or Mitsubishi Outlander PHEV already - the incremental cost to add bidirectional charging is $2,500–$4,000, and the energy backup value justifies it
• You own a Kia EV9 Earth AWD and park at home most nights - the bidirectional charger adds genuine whole-home backup capability at $5,000–$7,000 incremental cost
• You’re in the ACT or SA where V2G programs already exist with above-market export rates
• You have solar and a time-of-use tariff - the arbitrage value compounds with solar self-consumption optimisation

The V2G ecosystem in Australia is moving fast. CCS2 bidirectional infrastructure is expanding. More vehicles are adding support. Retailer programs are going commercial. In 2027–28, the case will be materially stronger as equipment costs fall and program availability broadens.

If you’re buying a new EV today and V2G is on your radar, choose a vehicle with confirmed bidirectional support - the Kia EV9 Earth AWD is the clearest option. The hardware investment is substantially less painful than retrofitting later.
