The concerns about lithium batteries being a fire hazard are dated and more theoretical than actual. The current LiFePO4 type for automotive use are highly stable. ...
Strange some people do not read the news papers.
A big car transport vessel is on fire at this moment around the North-Sea. ...
Welcome to TalkMorgan! Car transport ferries seemed to have a lot of accidents - plenty
of them are nothing to do with EVs!Interesting data in this
story:Although these fires do present a real danger, fortunately for us they remain very rare. Data obtained by Air Quality News through a Freedom of Information (FOI) request revealed that in 2019 the London Fire Brigade dealt with just 54 electric vehicle fires compared to 1,898 petrol and diesel fires. Although these fires remain rare, when they do occur, they can be extremely dangerous.That is old data, but if ~2% of cars are EVs, and 2-3% of vehicle fires were EVs, its only a slightly higher risk... but for a relatively new technology I suppose not unexpected. A counterargument would be ICE vehicles are likely to be much older...
Back to car batteries as opposed to EV... I have a Li-based "battery" (actually a battery+conditioning circuitry) and so far it seems good. I do trickle charge though as the car does seem to leak current / I have not yet fitted an isolator! I think an M3W is more at risk from broken fuel tanks than batteries...
When CCA - crank-capacity - is the issue.
I have a cheap and simple 40Ah lead-acid AMG - but you can use a smaller one too - when you put a super-capacitor bank parallel to it.
Great extra cranking amps. I have this now for 7 month and it works fantastic especially in wintertime.
Your battery will last 2 times longer and the capacitor bank can be sold by your heirs.
One extra tip : all batteries hate a heated environment - say > 40 C - so take them away from your lube-oil tank.
Very neat!
