What is V2G?
Most electric vehicles (EVs) today offer uni-directional charging. Once you’ve drawn power from the grid and put it into your battery, that’s where it stays until it runs out.
This lack of flexibility means you inevitably end up storing more charge than you need, which leaves a huge amount of energy sitting unused in EV batteries across the country. In fact, recent studies indicate that storing too much energy in a battery can even damage its health, meaning it wont last as long as if you look after it properly.
In addition, as more people move to EVs in future, with the majority charging them during peak times like arriving at work in the morning or getting home in the evening, we’ll see more spikes in energy consumption and more pressure on the grid.
We’re going to need a different way of doing things.
What if we could take unused energy out of EV batteries to use in other places?
That’s exactly what vehicle-to-grid (V2G) technology does.
By turning a traditional EV battery into a two-way energy source, we can free up any excess charge to power everything from buildings to other EVs, or even sell it back to the grid.
