Bidirectional EV Charging startup Ambibox GmbH has successfully trialled Bidirectional Charging (V2H or Vehicle to Home) with the Volvo EX30 without any additional modifications. Volvo which recently launched its energy business has been equipping its latest models with bidirectional capability.

The demonstration was shared on a LinkedIn post on Wednesday.cThe setup comprised a 2024 Volvo EX30 plugged into a Ambibox bidirectional charger. In the trial they were abe to discharge with a power range from 0.5 kW to 11 kW.
Ambibox CEO, Manfred Przybilla, noted that the "The dynamic behavior of the car looks quite promising. So, it should V2G capable". Interestingly no additional modification is required to the EX30. Przybilla confirmed "no software update on the car. We picked the car from the dealer and switched it on. What you need today is our HEMS, but we will allow other HEMS provider also in the future."
| Vehicle to Load, VtoL or V2L | V2L is the most basic application of bidirectional charging. It does not require a bidirectional charger. Instead, a V2L adapter is plugged into your type 2 charging port which allows the car to operate as a portable battery pack with a standard 120/240V power supply. |
| Vehicle to Home, VtoH or V2H | V2H involves using energy from your EV to power your home or business. This works in the same way a stationary home storage battery (like the Tesla Powerwall 2) does in reducing grid consumption, except your car needs to be plugged into a bidirectional charge point. |
| Vehicle to Grid, VtoG or V2G | V2G involves using energy from your EV to stabilise the grid. This is done through a ‘smart’ bidirectional charger, which is typically part of a VPP (Virtual Power Plant). Subject to defined parameters, your energy retailer will control when your battery is charged or discharged. |

Is Bidirectional Charging Available in Australia?
Vehicle-to-load (V2L) is currently available in several of the latest models.
With regards to V2H and V2G, South Australia become the first jurisdiction in Australia to permit the connection of bidirectional chargers in its network. The only bidirectional charger approved to be used in bidirectional mode is the Wallbox Quasar which needs to be connected to a Nissan Leaf to activate the bidirectional charging feature. As of the time of writing, no other states in Australia have permitted the connection of bidirectional chargers in its network.
It should be noted that the Wallbox Quasar needs to be connected to a Nissan Leaf which uses the CHAdeMO plug which will not feature in any new electric cars going forward in Australia.
In Australia, the dominant charging plug is CCS, which is yet to feature an EV with V2H or V2G. CharIN e.V, the body in charge of driving commercialisation of V2G/V2H for the CCS standard, has set a roadmap for commercial availability by 2025. This means we are at least twelve to eighteen months away from commercial availability of V2G and V2H in everyday commercial and household settings.
