This Southern California solar farm is using retired EV batteries for storing the power and then send to the grid when needed. This way the retired batteries can extend their usefulness for several...::A Southern California company is showing how repurposing EV batteries for stationary storage can extend their usefulness for several years.

Yea, with a car you can't really use them once the range gets low enough

With this, a bunch of batteries can work together for much longer. You also don't need to worry about weight since they're in one place

A Tesla Model 3, for example, has a battery capacity of 50 to 82 kWh. Let's assume the lowest capacity of 50 kWh. A car battery is basically unusable long before it has lost around half its capacity. So 25 kWh. American households on average consume 10.6 MWh annually or about 29 kWh per day.

So an old Tesla battery still provides enough electricity to power an American household for nearly an entire day.

Really puts into perspective what a monumental waste of energy individual traffic, also with electric cars, is as well.

Well, sort of, it's just that any sort of locomotion requires a lot more energy than you might think.

Yeah sure. But there's a difference between moving a 2 ton vehicle per person or a bike.

There’s also something about their peak current being reduced with age, and in this use case, they don’t really need that peak current, so they really can stay useful for a long time in this use case
