@ skk

Your post is very dishonest and misleading.

A few examples:

skk "Sometime after he left there was a small fire which was put out with a handheld fire extinguisher with no damage to the passenger compartment."

1: The Tesla that crashed burned and exploded in Mexico, the fire was not put out with a handheld fire extinguisher. The video of the Tesla fire and explosion in Mexico, shows a fireman putting out the fire with a heavy-duty firehose. The fire seems to first intensify as it was first hit by water, before cooling down and slowing down the reaction and putting out the fire.

2: Your assertions that there was no damage to the passenger compartment is also false. The video shows that some of the fire reached to the passenger compartment. The photos of the aftermath also show that the passenger compartment had some fire damage.

3: The fire was not small. The Tesla fire was a huge inferno. At times the fire appeared to be about 30 to 40 feet high.

If you're willing to settle for a Tesla, that's your choice. My standards are much higher.

If Tesla really was such a great vehicle, you wouldn't resort to fabrications to try to bolster its reputation.

Tesla's have a much better savety record then ICE cars.  5 years worth of cars in use and 0 fatalaties or serious injurys.  Is there any other car manufacture that can claim that?

Compare the recent crash of a Porsche that claimed Paul Walker.  Flat level straight road in perfect weather at mid day, no traffic, experienced race car driver in the drivers seat, car went out of control at 80-90 mph and hit a light pole and a tree, car burst into flames and killed both occupants despite multiple fire extinguishers trained on the car which had no effect of the gasoline fire.  

In the Tesla Model S fine in Mexico the accident happed at 3AM in the dark at a speed of "more then 100 mph", the road dead ended in a round about and the car smashed through the concrete block wall, went through a chain link fence and then went head on into a tree.  The driver jumped out unhurt and got a ride home.  Sometime after he left there was a small fire which was put out with a handheld fire extinguisher with no damage to the passenger compartment.  

I don't know about you but I would much rather be in the Tesla.

As for the two garage fires, the first one was a fire of the garage wiring which was of inadaquate size for current rating of the outlet and the wiring was not in conduit.  There was no fire in the car.  As for the fire in Canada what is know is that the fire did not involve the battery.  

300 deaths have been attributed to the GM ignition switch alone and you are concerned about the fact that in high speed sccidents that would not have been survivable in another car that there was a small fire afterward?

You have to consider that in the two US accidents that the battery underneath probably either saved the driver and passengers life or saved them from severe injury by keeping the steel beam and the tow hitch from penentrating into the passenger compartment.

Maybe what we need is a requirement that ICE cars be similarly armored on the underside?

@Pubudu: Statistics are not accurate mate. I'm not sure what methodology was undertaken for this but according to my knowledge statistics are very hard to be proved as accurate

ICE vs. Tesla fires

I just thought I'd throw in a curve ball here, this morning about 20km from where I live there was an accident with an ICE car and a family of 4 died because it burst into flames before they could get out. I don't know enough of the details to shed light on the validity in reference to any Tesla fires, but just thought I would flag this.

@ Leigh

Your post is rabid, rambling and incoherent.


Tesla uses lithium batteries that are more likely to catch fire and explode after being punctured than gasoline tanks. This is the real world, not Hollywood.

"Tesla fires have been statistically less than ICE fires. Surely you should putting more anlyasis into ICE fires, since A. There are a lot more of them B. They are more likely to catch fire."

Other reasons that you omitted for gasoline vehicles having more fires. It's some of the reasons that it is unfair and irrational the way you Tesla fan boys compare apples to oranges.

C: Gasoline cars generally have a lot more miles on them.

D: Gasoline cars generally are much older.

Compare apples to apples:

Tesla are more likely to have traction battery fires and explosions then other electric automobiles.


"The danger of a lithium based cells depends on chemistry.
Cobalt based cells (used in laptops, cell phones) are very volatile. Iron Phosphate batteries, which almost all electric cars use are relatively safe. I've seen crush tests and nail embedment tests where the cell temperature doesn't get over 120oC. Tesla also space out their cells to help prevent themal runaway."

 It seems as if you might be trying to deny that Tesla uses cobalt and it's lithium batteries. If you're trying to deny that Tesla uses cobalt in its lithium batteries, please source your information with CREDIBLE sources.

Allegedly according to Tesla Chief Technology Officer JB Straubel Tesla batteries use cobalt and other toxic substances in their lithium batteries.

"Iron Phosphate batteries, which almost all electric cars use are relatively safe."

It seems as if you might be trying to imply Tesla uses iron phosphate.

Tesla uses a type of lithium battery. LiNiCoAlO2 (aka NCA)

"Tesla also space out their cells to help prevent themal runaway."

Didn't work, did it? Three caught fire. At least one exploded.

You are repeating Tesla's talking points spammed all over the Internet. Before Tesla even had battery fires, I warned that their battery designs were dangerous. Tesla was wrong, I was right. Some of their precautions may have reduced some of the threats, but there battery chemistry and designs are still dangerous. It was reckless of them to locate a battery that is so poorly protected. so close to the ground.

At least three Teslas have had thermal runaways after an accident and only running over road debris. How many other electric automobiles have been made? How many of of their traction batteries caught fire and exploded in real world use after running over road debris or having an accident? Statistically Tesla batteries are more likely to catch fire and explode after running over road debris or having an accident; then other electric automobiles.

Jim, the bee in your bonnet is making you almost rabbidly irrational.

1. Tesla fires have been statistically less than ICE fires. Surely you should putting more anlyasis into ICE fires, since A. There are a lot more of them B. They are more likely to catch fire.

2. The danger of a lithium based cells depends on chemistry.
Cobalt based cells (used in laptops, cell phones) are very volatile. Iron Phosphate batteries, which almost all electric cars use are relatively safe.

Opponents are always going to play with such vulnerabilities to their benefit. Proponents should be careful, on the other hand, in criticizing media for reporting the news. Fire incidents are always reported everywhere irrespective of the cause. There is no point in becoming cynical about the motives of the media. The better course would be for proponents to increase pressure on the manufacturers to improve the technology and prevent such accidents from happening.

Yes, I am sure you're right, Chuck, thermal management seems to be the key. It will be interesting to see how this problem is solved at any rate.
