ID.3 V2G (Vehicle-to-Grid)
Posted: Wed Oct 27, 2021 2:54 pm
Hi
The VW Group wants to become the first major car-maker to start rolling out “vehicle-to-grid” (V2G) technology in all its electric cars to sell services back to the electricity grid and help stabilise fluctuating energy supply from renewables.

The first generation of MEB models that Volkswagen has been delivering since autumn last year is not yet designed to be bidirectional. These cars can only charge. Volkswagen will be able to retrofit V2G to those cars with comparatively few technical changes and additional software. Production should begin in December, and the bidirectional electric cars will go on sale after the turn of the year. At least 300,000 vehicles are likely to be manufactured at the VW plant in Zwickau alone in 2022.

Seems all VW EVs built after December 2021 will be V2G ready. VW will manage this system and sell battery storage to electric generating producers. The owners of the EVs will be paid a fee for allowing this. I am wondering who will pay for the new Bidirectional wall chargers? Plus any other kit the home will need?
Perhaps an other way an owner of a V2G EV could make good use of having a large KWh battery attached to there home would be to charge it up on low cost electric during the night and then feeding off the battery during the day time when electricity costs more!
This will depend if the EV spends day time at its home address or is away all day.
For me the ID.3 Max Pro will spend most nights and days just parked on our drive, as being retired commuting is a thing of the past for me.
I did the sums on the last 12 months of electric usage. about 7,000 KW day time and 2,000 kW during the economy 7 night time. I need to be able to store around 20 KW a night, at .08p per KWh and then use during the day. I would thus save 13p on each KW used from the battery or about £900 a year.
No doubt the will be other costs involved and losses in charging and then discharging the ID.3s battery.
One thing I did note is VW seem not to be too worried about V2G battery degradation.
