The journey of bidirectional charging in Australia has hit an important milestone with the recent approval of the new standard for vehicle-to-grid (V2G) charging.
Recently, Chris Bowen, the Minister for Climate Change and Energy conducted a speech at the 2024 Sydney International EV Show, speaking about bidirectional charging and V2G breakthroughs in Australian standards for this emerging technology in the Consumer Energy Resources (CER) roadmap.
Note: As of this article, there are no official V2G or V2H solutions available. If you'd like to order one, please sign up to our updates list and we'll keep you updated.
Bowen identified that the priority to give households control over their energy whether from rooftop solar, solar battery storage, or in the battery of their electric vehicle.
“The other opportunity we have in our renewable energy transformation is to ensure that households are in charge of the resources that they have available to them: on their roof, in their garage – in their battery in the garage, and increasingly in the battery that sits in their driveway.”
“I'm very pleased to announce today that one of the important milestones in that Consumer Energy Roadmap has been ticked and that Standards Australia has ticked off the new standard that will allow vehicle to grid charging in Australia.”
Here’s what the Energy Council’s website says: ‘With the grid intended to serve customers, not the other way around, customer interests need to be front and centre as the roadmap is rolled out.’

By supplying your energy back into the grid during peak demand periods, EV owners can make money by selling
energy when prices are high, and charge when prices are low, maximising your EVs investment.
Because of the extended amount of available energy storage, solar can be maximised throughout the day by
storing excess energy, which can then be used later when the sun is down, reducing most overall grid and supply stress.
Like dedicated batteries, by having a V2H capable electric vehicle, you have access to backup energy with V2H
during grid outages. This ensures your lights stay on with greater energy independence.

With the new Australian Standards in place for bidirectional charging, Bowen said that manufacturers can start getting their bidirectional products refined to the new standard, and then put in an application to the CEC for approval.
“They'll have to meet the standard that's been ticked off by Standards Australia, but where we've got manufacturers and OEMs who are on board for that and it all happens smoothly, we'll be able to have bidirectional charging a reality by Christmas this year.
So, I really am encouraging manufacturers both of vehicles and charging infrastructure to get their act together and get their applications into the Clean Energy Council - I'm sure they will, they've been waiting for this - as quickly as possible so we can make it a reality.”
In our previous article around bidirectional charging and why it is taking Australia so long to get this technology available at-scale, we looked into how the lack and confusion of Australian standards around bidirectional charging where a contributing factor into why manufacturers haven’t invested into this technology in this nation.
Recent changes to the 2016 standard, AS/NZS
4777.1:2024 for inverter energy systems, accommodates changes for new technologies including vehicle-to-grid. AS4777.2 is set to be revised by early
2025, looking something like this,
depending on the official version.

With this new standard specified by Bowen, this completely changes the game with the doors opened to manufacturers of both charging
infrastructure and electric vehicles to implement, market, and feature V2G technologies in their products. As Bowen mentioned, they
already have manufacturers who are on board.
Ausgrid has mentioned that they currently allow V2G EV chargers on its network, as long as they meet the same requirements as solar and battery installations, meeting the AS/NZS4777.2 standard and CEC approval requirements.
Companies like Hyundai, Kia, Nissan, and Volkswagen have either already implemented, or announced bidirectional charging capabilities. U.S specifications of the Tesla Cybertruck show that it also has bidirectional features via Tesla Powershare.
The Consumer Energy Resources Roadmap, supported by a partnership between RaceFor2023 (led by enX) and ARENA, is being developed to allow mass-adoption of bidirectional charging in Australia.
According to RaceFor2030, the Australian V2G roadmap will help the CER roadmap by unlocking potential pathways to encourage commercial adoption of bidirectional technology in Australia.
It will help consult policy development and investment for all sectors and enable commercialisation.
They state that the completion of this project will be completed by December 2024.
Bowen also said “Vehicle to grid charging is now ticked, enabled under the law of the land and will become a reality before Christmas, in the real world. Possible today, technically possible today, thanks to these changes, but next couple of months, an opportunity for the companies to get their registrations in and get it happening.”

Like current solar and battery technology, vehicle-to-grid technology manufacturers will need to register their products through the Clean Energy Council for approval. Here’s the approved battery list for example.
“And the process from now is that those manufacturers that enable vehicle to grid charging and those charging companies that enable it can register their products with the Clean Energy Council and get approval for each particular product.”
Because of the Australian standards being recently altered to allow for bidirectional charging, we expect that over the next few months that we’ll see charger and EV manufacturers submitting their products for refinement and approval through the CEC to be ready for the Australian market.
During the speech about standards, Bowen also said, “Vehicle to grid charging is now ticked, enabled under the law of the land and will become a reality before Christmas, in the real world. Possible today, technically possible today, thanks to these changes, but next couple of months, an opportunity for the companies to get their registrations in and get it happening.”
We expect to start seeing compliant bidirectional chargers to reach market at the start of 2025.
We expect bidirectional chargers to become available in Australia in 2025 with companies already announcing their goals to have chargers out in 2025. With Australia only recently announcing bidirectional charging in Australia, companies will need to get their chargers compliant to Australian standards, and CEC approval.
Companies like RedEarth, Sigenergy, Wallbox, as well as other EV charger manufacturers have announced that they have bidirectional chargers either already available, or in late development. Each company will be at different stages, but Sigenergy, Wallbox, and RedEarth seem to be the closest to having their bidirectional charger available in Australia.
Wallbox hasn't yet announced the release of their Quasar 2 charger. RedEarth has partnered with ambibox to start production of a three-phase V2X charger in Queensland to possibly be available mid-2025. Sigenergy has a bidirectional charger currently available to buy, but the approved product list will most likely still be in development.
A question we had was if dedicated home and commercial battery adoption would be affected by the increased use of electric vehicle batteries. We don’t think that this will greatly affect the adoption of dedicated batteries as they will still serve a purpose that EVs may not always be able to fulfil.
In a situation where an electric vehicle owner goes to work, they may park their car in a car park without chargers. Their solar system back at home will generate electricity and store that excess power into the dedicated battery.
When the person arrives home at peak hours during the early evening, solar is no longer available for that day, leaving only 3 ways to charge the vehicle; with expensive grid energy in the peak period, cheap grid energy after 10pm, or the stored solar energy in the dedicated battery.
Another reason could be that your electric vehicle battery capacity is only really suitable for your daily commute and not to power a house for a period of time. People are also aware of what the increased battery usage could do to the battery’s lifespan.
Essentially, a dedicated battery allows for more options for cost savings and sustainability, resulting in greater energy independence.

For properties with solar and dedicated battery storage, electric vehicles with vehicle-to-grid technology would be an integrated addition to the property’s energy production, storage, and consumption.
By having an integrated vehicle-to-grid system, your property will have elements that all serve a purpose for your energy. For example, an EV would allow you to soak up excess solar energy that would typically charge the dedicated battery, and then fed back into the grid. These sorts of systems are integrated to help reduce your overall energy costs and optimise usage to consumption balances.
In the future, we believe that an EV would act as a home battery, allowing owners to join a Virtual Power Plant and participate with your EVs battery. As we’re in the technology’s infancy, we are still trialing this technology, like the Amber and ARENA trial which is set to test how it would work.
Having vehicle-to-home and vehicle-to-grid available for microgrids and virtual power plants would allow for greater energy security and investment returns by expanding the capacity of energy. You not only could store more solar, but buy cheap energy through off-peak times, and use in replacement during peak periods to avoid paying for electricity when it’s most expensive.

Overall, it’s really encouraging seeing the Government take on this new technology and begin to accelerate its development.
With the new standards being amended, we should start to see manufacturers of electric vehicles and charging solutions begin to release products into the Australian market over the next year.

The journey of bidirectional charging in Australia has hit a milestone with the recent approval of the new standard for vehicle-to-grid (V2G) charging for 2025.
Amber & ARENA have started trials for Vehicle-to-grid technology in NSW, Australia to help develop standards and framework in V2G and Bidirectional charging.
Though bidirectional charging isn't available, vehicle-to-grid is already turning heads in Australia with its potential to change energy consumption and distribution.

Every household that puts into place a islanded solar / battery / EV self sufficiency system in the event of extended power outages should get an insurance premium discount. Same for flood, fire etc. Households and businesses with such plans should pay a small annual inspection fee to make sure their systems are fully maintained and operational.
