Just remind me how EVs are better for the environment again?

As an ex seaman who’s fought lithium and oil fires at sea I’d go for oil any day. They were lucky there was some wind to clear the smoke from the upper deck.
 
Those ships would be impossible to fight a fire in, they are just great big caverns with no compartments at all to separate into zones. I have searched quite a few of them in a previous life.
 
Class D, graphite powder and some other compounds is the only medium that I’m aware of that deals with Lithium. As far as I’m aware there is no automatic drenching system for compartments with this medium just portable extinguishers.
Burning motorways may be a problem in the not so distant future.
I only own one large lithium battery and it got charged in the garden yesterday while the weather was good.
 
My first thought was ferries. Reading the reports of this container fire, If you’re on a ferry when a EV car goes up you’re in trouble.
 
This firefighter / mariner has hit the nail on the head and is well explained in his video. Quite often in the marine world the left hand doesn’t know what the right hand is doing!

 
Apparently the lorry went up and the driver pulled up sharpish, the cars didn't start it. Makers are increasingly turning to LiFePo4 as us camper chaps have, and they don't burn even if you take a blowtorch to them.

I thought the probability of thermal runaway with LiFePO4 chemistry was very low, but not zero. :confused:
 
Seen reports of a few car carrying ships going up in smoke lately.
Apparently some shipping companies have refused to carry milk floats on board.

The chemistry doesnt release oxygen so they're incapable of a runaway self-propagating fire in the manner of Lithium Ion batteries. They can runaway thermally locally within the cells, but dont burn.

I was, however, overly simplistic. If you short or puncture them, for example, there is the risk of fire. However, rhe mechanisms involved there are akin to a lead acid battery going pop (and they sometimes do) as a result or the voltage potential, but not because of the chemistry.

In short the cars didnt send this lorry up.

There are plenty of places for statistics on the number of EV fires vs ICE fires.

Global studies show ICE vehicles are 80 times more likely to catch fire although a study in Sweden showed ICE cars there were 20 times more likely to catch fire than EVs.

It’s long been established that it is pure myth that EVs are more likely to catch fire.
But yes, they are harder to put out if they do catch fire (although, like everything in life - practice makes perfect.).

Let’s face it, if we want vehicles with less fire risk we need pedal bikes or horses.

Personally I think progress and choice are better than being 100% risk averse and blindly sticking with things that we know aren’t perfect.
