Weniger als 10 Menschen in ganz Australien tun dies tatsächlich, denn die Technologie-bekannt als Fahrzeug-zu-Gitter (V2G)-ist sehr neu. „Eine Hausbatterie, die Sie herumfahren können“.

„Bidirectional EV charging allows for EV batteries to be used for purposes including solar-self-consumption, back-up power and supporting the grid. With the right policy settings, hundreds of thousands of Australian households could be using this technology to reduce their power bills by 2030, and millions by 2040.“
Quote from [this report](https://arena.gov.au/assets/2025/02/Bidirectional-Bidi-ROADMAP-2025-01-15-1.pdf) linked by the Guardian article.

I don’t want to sell it to the grid as much as use it myself to collect excess solar during the day and use it at night. I don’t drive to work so my car is at home 90% of the time.
Does the increased use/discharge affect the lifetime of the battery?
One day it would be nice if all EVs were connected to the grid at all times when parked. They alone maybe could provide all the storage we need to be fully supported by fickle renewables of wind and solar. But in order to convince EV drivers to do it, they have to be able to sell electricity for more than they bought it from (probably buy during the day, sell at night). Wouldn’t it be neat if governments made a law that the electric company can set whatever price they want for electricity, but they have to accept buys and sells for that price. Kind of like buying or selling a stock at a given price (similarities end there). I wonder if this would be a good idea for governments to pass this law.
I recently had a conversation with a few people about power outages after a storm where we live and they were saying that they are glad they have a regular car as they couldn’t charge an EV during a power outage.
They hadn’t heard of VtL. They changed their minds when they realised they would still have power for essentials for a few days and can drive to a charge point and come back and get another few days.
