A Southern California company is showing how repurposing EV batteries for stationary storage can extend their usefulness for several years.
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.
Good idea but good luck to the people who will try to take the fire out
Edit: I’m not saying that it’s bad, of course renewable, solar, electric is good. But knowing how horrible electric vehicle fires are to put out, I don’t see a fire of piled up batteries being an easy challenge for firefighters
Lower risk yes, but also harder to put out yes, and also the comparison here isn’t about cars at all.
It still shouldn’t be an issue as long as you place the storage somewhere where the fire can be contained easily, then worst case the whole storage burns down but there wouldn’t be significant collateral damage.
This is a way to get off gas as it’s used for reliability and voltage regulation. There’s a few locations running pilots with different energy storage techs like this. One of the main problems with integrating renewables is they aren’t dispatchable generation so you’re basically throwing unknowns in to the system. This is mediated through programs like demand response and load following with gas, but the goal of decommissioning gas and fossils entirely while still providing reliability is hampered because of this gap in capability. Renewables paired with storage would accommodate more less flexible renewables and SMRs, and allow for more electrification of the economy with less climate impact. More electric arc furnaces!
Sure… at roughly the same rate and/or lifespan as someone with a combustion powered car might need to rebuild their engine or transmission. It’s really not that big of a deal, and newer battery chemistries like the current LiFePO packs are continually getting longer and longer lived. BEV battery packs are already expected to last 10 to 20 years.
The article mentions that they mostly use batteries from the Nissan Leaf and Honda Clarity. I’m not sure about the latter, but the Nissan Leaf does not have any kind of battery management system. That keeps the battery warm in winter and cool in summer, and helps it last a lot longer. Nearly every major EV on the market does this, but the Leaf is the big exception. It’s also the one car where you’ll see severe range degradation on an older model.
At one time, they didn’t last more than a few years, and needed expensive replacement. Newer batteries have better BMS controllers on them and last a lot longer. But any damage pretty much necessitates replacement. The batteries can probably be fixed but IDK if they can be put back into use in vehicles then. So there’s plenty of used batteries that can be upgraded to use for stationary storage. You can buy them all day long on certain websites or auctions. It’s a pretty popular thing for DIY solar.
Sometimes, but not often. These are mostly 1st gen EV batteries, so they’re pretty old. It’s mentioned in the article that once capacity diminishes to the point of effecting range the old battery is replaced. Old units can be refurbished. These units could also be situations where the car surrounding the battery failed (accident, hail damage, etc) and they decided to scrap it and reclaim the battery.

So like… do electric car owners just need to buy new batteries? That’s the most expensive part!

This should make it less expensive if EV owners can sell their old batteries to be turned into a grid battery.
