Battery struggles in the cold explained

Rechargeable batteries are great for storing energy and powering electronics from smartphones to electric vehicles. In cold environments, however, they can be more difficult to charge and may even catch on fire.

I’m a mechanical engineering professor who’s been interested in batteries since college. I now lead a battery research group at Drexel University.

Surprisingly petrol also tends to sometimes combust when involved in an accident and these cars often burn out. Yet we don’t get investigative professors worrying about it much.
Thankfully lithium batteries in cars have both heaters/coolers integrated as thermal management to optimize charging and discharging in cold and hot weather. The first Nissan Leafs that we have here don’t have active cooling that’s what each one has a shot battery. I wouldn’t but a secondhand one.
I’d think the auto manufacturers also wouldn’t offer an 8 year warranty on the batteries if this were an issue
 
I know I would rather trust respected researchers who are experts in the field of battery safety than some idiot on MyBB forums.

These videos are from 2023 and shows some of the ongoing research into the inherent hazards of lithium based batteries.

This should wake people up as to the dangers of Lithium based batteries.

I sure hope that some of the other areas of research in other materials pays off as I for one don't trust Lithium based batteries - especially not in cars.

Some education for the "experts" :p

Before I watch - are these lithium-ion or lithium iron phosphate batteries?

I don't even need to watch them to know its lithium-ion because I know LFP doesn't burst into flames.

But lithium-ion is terrible tech compared to LFP.
Do electric vehicles actually use lithium-ion or just some.

electrek.co

Government data show gasoline vehicles are up to 100x more prone to fires than EVs

Aside from the argument that gasoline vehicles operate via combustion, a study shows how prevalent gas vehicle fires are compared to EVs.

Carry on with the misinformation...
 
As expected from the MyBB experts such as @Sinbad d and @wingnut771

Checks Sub-Forum posting in: Check: Yup. "Motoring and Transport" (not your home battery storage system in other words - but some people do have Lithium-ion in home systems as well, so can be applicable to those too).

Checks videos I shared which doesn't come from MyBB experts, but from people with actual years of research on the topic of batteries and which focuses on fires specific to, but not exclusive to batteries in Electric Vehicles.

Confirm they didn't even watch the videos, but trust their own "research" (in home battery systems).

I wrongly assumed I was not dealing with 30%rs who have to have everything explained to them in crayon pictures. :rolleyes:

Various EV manufacturers are discussed in the videos.

But they do discuss other forms of batteries as well.

How is this relevant?
We know there are different chemistries at play.
My point is, EV fires are MUCH rarer than ICE fires... so what are you trying to argue?

LOL - "How is it relevant?"

Ok Professor.

You haven't watched the videos from your "peers" yet hey? It shows.

Don't understand the increasing frequency, but also the more violent nature of EV battery fires vs. ICE considering the relative age and few EV vehicles on the roads.
Still don't understand the difficulty in extinguishing an battery fire vs fuel fire.

You guys (I bundle you into the same group as ol Wingnut behind you) still think LFP (LiFePo4) batteries cannot catch fire and I quote "I know LFP doesn't burst into flames."

Carry on MyBB Professor. I don't want to spend 86000 posts of my life arguing on the internet.

I gave valuable information, you chose to ignore it and ridicule it as "misinformation".
Your type just spoils for a fight at any opportunity in "your domain". Not worth it.
