A negative aspect of Electric vehicles.

Recommended Posts

EVs have good potential and promise.  However, you don't get somethng for nothing.  The bill comes due.  There are costs to produce and distribute electricity.  There are costs to make electric batteries, regenerating systems that use rare earth magnets, etc.  both dollars and environmental.   Legislation in many cities and states and even countries seem to be pushing towards mandatory Electric Vehicles.  Time will tell

I think the odd petrol car catches fire sometimes, probably more common and in greater numbers than electric. A quick YouTube search show 100s of examples.

There is a fire clause and coverage in insurance policies, so it does happen.

Over time, the batteries will become way safer than they are today, the Chinese BYD is leading with their blade battery design:

 

It's very impressive but I think solid state batteries are going to have the edge. They are inherently non flammable, can hold a greater charge than batteries with a liquid electrolyte, and charge more quickly. Not so long ago a Toyota powered by a prototype solid state battery was spotted on a highway in Japan.

It would be interesting to get numbers for vehicles fires per million or billion miles driven for both gasoline and electric cars.

Arson subtracted of course. 

In all fairness, you would also have to subtract the Karen's driving away from the gas pump with the fuel hose still attached, lots of fires from those fiery characters.........lol

My MG EP, after beating the <deleted> out of it for 15 minutes, hitting the rev limiter multiple times on the AC Motor (15,000 RPM!  Yes that renders a very high speed of travel, but we have the roads in this area to support that, if you know where the cameras are), then stopping and checking everything under the hood and the battery with infrared thermometer....   Hottest temp seen:  56 Centigrade!  You'd be seeing temperatures in excess of boiling throughout the engine bay of an ICE car if driven the same way, and exhaust manifold temps multiple times those temperatures.  The AC compressor motor which cools cabin, motor and most importantly battery pack of the MG EP is sizeable...  like that of a large van.  Could it blow up?  I'm sure...  but I'd say less likely than a benzene-powered, under-maintained POS ICE car here in Thailand.

 

If you want safety in a car, drive a diesel.  You can drop a lit match into a barrel of diesel and it will literally just snuff out.

 

What boggles my mind are the legal 'bomb cars' fueled by LPG, LNG etc driven around here.  THOSE are completely insane IMHO.  I'll take my BEV any day over those!

More damage is caused by CO2 pollution than a few electric cars burning.

More damage is  caused by destroying perfectly  good sound running petrol/diesel  cars for the "sake of the environment" when buidling a new  car must use a sheite  load of resources...make do an mend same as  the 2cv mentioned  above.

Have a look at the negatives of fuel vehicles.

Same as the discussion about driverless cars. The other side is way more deadly.

Or, what do you think of this:

If there's one thing that is consistent is that the predictions about the progress in battery technology has been uniformly too conservative.

For one thing, the drop in the cost of lithium ion batteries has dropped dramatically.

And there are plenty of predictions out there that counter Samsung's.

yes they are a scam, look at Tesla, replacement batteries after end of warranty are still so expensive, I would never buy one.

 

I agree with you, many different types of Lithium batteries, when you  take for example the 18650 batteries, average they stay long, but the batteries in my DJI drones worn out very quickly, but compete different types but both lithium.
