Retired EV Batteries used in Charging Stations

Companies are seeing value in using old EV batteries as Renewable Storage mechanisms or EV Charging Stations.

EV batteries degrade as they are charged and discharged. Drivers can expect upward of 100,000 miles of use before a battery loses 20% or more of its capacity, roughly the point at which performance drops noticeably, experts say. But they remain useful for grid storage until their capacity drops to around 60%, potentially giving them another 10 to 15 years of service, according to Hans Eric Melin, founder of Circular Energy Storage Research and Consulting.

Recycling of EV batteries is becoming a huge industry. This article talks about using the retired EV batteries as energy storage. China now accepts retired EV batteries from around the world. They have large numbers of batteries that are used in some EV charging stations. Once they are no longer capable of being used for that, they are recycled.

China has even been buying used EV batteries from overseas, Bao Wei, the general manager of Jiangsu Huayou, a recycling unit of Zhejiang Huayou Cobalt, said at a forum in Nanjing recently. Bao described the now millions of EVs that are on the roads globally as “moving metal mines.”

It’s a concept Elon Musk touched on too at Tesla’s annual general meeting on Oct. 7, saying you can think of batteries as “essentially high-grade ore.” “So you can either get your lithium and your nickel and the various constituents of the battery from rocks, or from batteries. It’s much better to get them from batteries,” he said.

After Jiangsu Huayou buys retired batteries, some of them are used in energy-storage applications, where aged cells are still useful. Then after a while, their key ingredients are extracted and sold on to battery makers, creating a perfect circle. It helps lower EV-battery-making costs by up to 20%, according to Bao.

 

China has a problem with their batteries going cremation mode.

 

Yes! This will become more and more a “thing” and one I have long told the nay sayers focussed on the environmental “cost” of these batteries

 

Borg Warner, who supplies Detroit automakers with many of their parts has just signed an agreement with BYD (China) for the exclusive market rights to their Blade Batteries in the US. Take a look at this battery. It even exceeds the requirements of the "Nail Penetration Test".

BYD's blade battery is revolutionary in several ways. We are happy to explain why this is the case, as well as the importance of the so-called Nail Penetration Test.

One of the most important parts of an electric vehicle is the battery system. After years of study, research and development, BYD has come up with the Blade Battery. What is so special about this system? Blade Battery offers new levels of safety, durability and performance, as well as increased battery space utilisation.

Another unique selling point of the blade battery – which actually looks like a blade – is that it uses lithium iron-phosphate (LFP) as the cathode material, which offers a much higher level of safety than conventional lithium-ion batteries. LFP naturally has excellent thermal stability and is substantially cobalt free. LFP is also a very durable material.

Yeah China is full of ****

 

Tell Borg Warner that:

BorgWarner Inc. is an American automotive and e-mobility supplier headquartered in Auburn Hills, Michigan. As of 2022, the company maintains production facilities and sites at 92 locations in 24 countries, and generates revenues of US$15.8 billion, while employing around 52,000 people. The company is one of the 25 largest automotive suppliers in the world.

 

They will find out soon enough

 

How arrogant! Like you know more than all the Corporate highly paid experts that were involved in this massive mulinational corporate deal.

 

Well all you have to do is look at every other corporation that's done business with China.

Yes I know more because I'm not blinded with dollar signs.

 

Like Tesla?

 

Tesla suffers from poor build quality. If they started sourcing the batteries from China this will probably be a problem.

 

CATL already provides batteries for some of Tesla's cars. The EV world is full of International agreements between corporations, all trying to figure out who will come out on top.

Just when I thought that CATL and BYD are the undisputed battery leaders (and they currently are by sales), I hear about a US company, 24M, that is close to a 1000-mile range EV battery. Ford is making a lot of headway on a battery that won't suffer reduced mileage at very cold temperatures.

https://cleantechnica.com/2024/02/14/24m-claims-the-1000-mile-battery-is-nearly-here/

 

Oh poor build quality on top of questionable batteries more reason not to buy a car from Tesla.

That'll be cars that run on fuel. They triumphed over electric cars all the way back in 1901.

Right they're magical battery that violates the laws of physics.

If you knew a little bit more about how batteries work and why they do so poorly in the cold you would understand why 24-m is full of ****.

I know.

 

Yep! Research is powering ahead on this meanwhile



lols!

 

A battery that provides a thousand miles of range would probably weigh the same as an entire Tesla.

Or what you would have to do it's either produce more cells or find a magic material that's that's solid state or it can be held in a solid state to use as an anode.

So I simply know better than the fall for the horse ****.

Many people don't understand how batteries work and particularly why they use lithium instead of something else.

Have you ever wondered why the accessory battery in a car is not a lithium ion battery do you have any idea why do you know anything about batteries at all?

I made a bet with myself that the response to this thread would be an attempt to take it off topic nd I am glad I was not disappointed

 

That did happen, didn't it And I must admit, I participated in some of the off-topic discussion. This is sad, because there are a lot of exciting breakthroughs going on this field. I forget where I saw it, but one EV charging station in China had hundreds and hundreds of these retired EV batteries wired together inside a building. They would charge them in banks, while other banks were used to charge the automobiles as they plugged in. What a great way to store renewable energy, using old EV batteries, and use it to charge the vehicles.

 

Superb news.

 

Why would they want retired batteries for electric charging stations?

What is the point of it?

 

Is that what you think? Then you must know the answer to my question.

(I hope you're not celebrating something you don't understand)

 

Charging stations or anywhere else where electricity storage is required. For example storage of power while renewables are supplying, to use later, when the renewables are not producing. The storage of the power is the key. The use can be anything.

 

Why would electric storage be required at charging stations?

That does not seem very particular to charging stations.

How many charging stations are you aware of that produce their own power?

Or are we discussing a different type of charging station, not the type of charging station that electric vehicles go to?

But the title at the top of the opening post said "EV charging stations"

 

Yes, I saw a video showing a Chinese charging station. Cars were plugging in, and the the inside of the charging station had hundreds of retired EV batteries. The video didn't specify how the retired batteries were getting charged. My background is Electrical Engineering. Theoretically, by wiring these batteries in a certain manner, some parallel connected, and some series connected, you could get exact charging voltages and currents without the use of invertors. I'm curious to learn more, but I'm not sure the technical info is available.

 

But that would probably not be the most electrically efficient. Usually for that purpose smaller capacitors would be used -- much lower power losses.
