Do You need help to find EV and HEVs in fire on parking places?
Or those burned on the road with no collision?
Check the Police BMW burned in Rome.
Why are all your pics of the car damaged? Probably before the fire was an accident? Also, how much burning of cars with standard internal combustion engines? I think that these statistics are not in your favor.

2010 Toyota Prius Hybrid Fire
There was such a blow
Where are similar fires from crash tests?
Crash tests give no explosions or fires and in the Real World the Electric Cars are unsafe?
Is this about the evidence of fake safety tests for EVs to put them on the market and after that starting the rhetoric about statistic?

Prius in fire
I have seen videos of burning laptops, when it starts smoking, you start walking away. So you're safe.
For sure, the last recall is about to hold laptops and smartphones near passengers.
But Boeng have the own batteries to burn.
Do You have seen some tesla side crash test with flames?
Why they are burning on the streets?
Someone is hidding how tests goes in real.

I'm sure, that people have seen not much enough electric vehicles in flames.

Someone, who not used the salt with added iodium can thinking surely, that if Russians are promoting teeth cleaning, there is a complot.

I like that Russian began to promote the rejection of electric cars. This means that alternative technologies are developed, improved and already making trouble for countries trading in oil. The price of fuel will fall to stop.

Spontaneous combustion of electric car is a rare event?
If there is no statistic, how do You can tell it?
Renault Zoe
Why you are not worried about?
I don't like to worry about irrational fears.You're Russian, right? 27000 people died in traffic last year in Russia. I doubt electric car fires caused any fatalities (other than traffic-related).
Unfortunately I can't find any videos of a starting fire in an electric car (people only start filming when it's big already), but I can imagine the fire starts slowly, giving you time to get out of the car. Unless you're stuck after an accident, but in that case burning gasoline isn't going to save you either.
Electric cars have different issues than fossil fuel cars. Showing some pictures of burning cars without the proper statistics has nothing to do with the question you frame here.
Seems You have no such statistic, and no one publish it.
Why you are not worried about?
This is in nature of humans to think, that accidents goes to happen to other people.
Footage of burning Electric Cars.
Impressive pictures. Allow me to show you a burning gasoline tanker truck:
My point is:
Lithium is a fossil
Wait, what?! Is this your translation or are you just making things up?Here is about the explosive nature of Li Ion batteries.
This describes it nicely. Lithium batteries need active protection to prevent them from damaging themselves. When they're damaged/overcharged/undercharged/overheated, they become unstable.Don't forget high-power-batteries are still relatively new, development is still ongoing, and road-testing is just part of this development.
For the record also, the Prius uses NiMH batteries, not Lithium.
Chevy volt use lithium ion batteries not too, but it burn.
And what is burning in MIEV (picture in this thread)?
The fire in Prius from the wrong side is a big argument.
You need pictures of Prius with fires from other side?

Prius
Chevy Volt in fire
The safety problem is evident. High Voltage caves connected to the batteries and burn too, and the problem is connected still to Batteries in EV or HEV.
an example of a fire in a Hybrid that has nothing to do with the car's HV system.
How do You detect the origine of HEV fire?
The same way you detect the origin of any fire, inspection of the site post fire.
What is clear in the Prius picture is that the car's batteries are not the cause of the fire as they are located in the rear of the vehicle; possibly an issue with the Prius's HID headlight.
For the record also, the Prius uses NiMH batteries, not Lithium.

“Lithium-ion batteries are a known safety risk,” says Karen Walker, editor of Air Transport World, an airline industry trade publication. “If they catch fire, it’s a very intense heat. And fire and aircraft don’t mix very well.”

When a battery malfunctions, according to Consumer Reports chief scientific officer James Dickerson, it’s usually because the membranes that separate the charges in the battery are breached, which creates a short circuit and generates a sudden release of energy. That violent burst of energy causes the battery to reach temperatures approaching 1,000° F, potentially destabilizing nearby batteries, creating a condition known as thermal runaway.

Call to this mr. James Dickerson with the theory of "cheap Chinese crap", he have no idea about it.
Leaf fire appears to have started in the HV ECU circuits or an HV accessory (heater perhaps). My guess is a IGBT shorted, took out its partner, and dead-shorted the 400v line. Normally this would cause the fuse to blow in the pack, but if the IGBTs kept the current below 200a then you would have a nice little 200*400=80kw space heater under the hood. That could cause a nice fire t which point the contactors would drop out and the car would burn at a normal pace.
Kind of like having a gas engine fuel injector line fail. Gas all over the place, one of the 30 cars a day that catch fire.
Now to design this problem out is difficult: Normally the IGBT controllers have current sensors watching the current from the Source to Drain, looking for an increasing voltage that exceeds a reference standard (a sign that the IGBT is shorting out). In the old days that would feed an Op-Amp with the output being directly tied into the gate driver shutdown line of both IGBTs. Thus if a FET shorted it's neighbor would see the current screaming up and instantly shut down the gates, then signal the controller to drop the contactors (which electronically speaking takes a lot longer, thus you want the immediate gate shutdown). Wonder what happened. However the lack of Leafs exploding around the country leads me to believe this was an edge case.
In terms of the two cars above, both look to be crappy power in the garages they were plugging the cars into. See "Don't use a cheap portable charger plugged into an old wall outlet". Hm. I wonder if they had aluminum wiring in the house... Probably the closest analog is a dryer fire (2,900 of those a year in the US)

It's not the battery per se: I have melted a pack of flooded NiCd cells in my time and have also managed to explode Prius NiMH cells while testing. The results are hilarious to say the least, but nothing compared to my friend who blew the bed off his S10 pickup truck when he forgot to vent the hydrogen gas from the NiCD batteries he put under the bed.
Yep, off. It was kind of funny actually.
The problem with the hoverboard crap is regulating the charge properly. Charge to 4.1 volts per cell, then STOP. Too many cheap Chinese chargers will charge the pack to 4.1v*number of cells, forgetting that if a cell goes above 4.2v it will gas, overheat, go into thermal runaway, and burn. This is not something demonic and magical, it's common sense. As much as putting a lamp shade around a 100 watt bulb because if you knock the lamp over into a pile of newspapers they will catch fire as the bulb heats the paper. (This is also the fundamental method of operation of the Easy bake Oven).
But it needs a charger that you take some time to design properly, in Chinese make-it-cheap town they just throw together a constant voltage lead acid charger and call it a day. No UL listing, people don't care, house burn down.

This is why cheap Chinese crap can catch fire. And why a lot of cheap Chinese crap is banned in the US.

This is a basic property of Li Ion batteries, not about failures in quality.

Ford recalls 570K vehicles for fire risk, door latch trouble
http://www.cbsnews.com/news/ford-recalls-570k-vehicles-for-fire-risk-door-latch-trouble/
...The engine fire recall... In Europe, the recall covers the 2010 through 2015 C-Max hybrid
Oi. Where to begin....
1) if you do not have a battery management system on lithium batteries, you can overcharge them with a cheap constant voltage charger. What happens is one cell in the pack over-charges, heats up, then the voltage on that battery goes down so the charger keeps feeding power. The result is called thermal runaway, which either melts the pack or causes a fire. This is why cheap Chinese crap can catch fire. And why a lot of cheap Chinese crap is banned in the US.
2) Another cause of battery fires is dead shorts of the electrical system. In the case of two teslas, it was having chunks of metal pierce the battery box. A Leaf is less likely to have this happen as they have a serious battery plate on the bottom but it still might happen. However anything that hard of a hit would pierce a gasoline tank with the usual results (see 30 car fires a day).
3) It is true that flooding an electric car can cause a short and fire, however at that point the average lead car is leaking gasoline into the water which floats and can catch fire on the surface of the water. Shit happens.
4) The big problem with EV's is that when they charge they pull a lot of current. Dryer levels of current. If you plug them into an under-rated circuit, or into a home circuit that was designed to supply 15 amps or so maybe with old wiring you *CAN* overheat the plug and wires which CAN cause a house fire. This is why you charge a car with a dedicated EV charger and wiring going back to the fuse box and have it done by a LICENCED ELECTRICIAN, not a twinkie who thinks he can install one because he changed a light bulb.
Note I fall into category 4: I have a 1990's era EV that I converted to lithium/Leaf pack. It charges so long now with the bigger pack that I wound up melting the 15a 240 volt 6-15 socket I installed outside. So I upgraded it to a 6-20 and all is well now. But a proper electrician would not make such a bone-headed mistake.
Note 2: A number of bitcoin mines have caught fire due to the exact same problem. I wonder how many house fires miners have caused and never reported.
So yeah, it can happen. However it also happens that due to faulty tubing, poor design, and just plain bad luck plenty of gas cars catch fire too. On my 80's era 944 I once saw that a fuel hose had a bulge in it, right over the exhaust manifolds. I switched out the line of course, then found that one of the two layers of rubber had leaked. If it had broached the second layer that car would have exploded on the highway like some cartoon car. And it turns out a number of them have....

Fixes broken miners because they really are the same things as the 400-600 volt EV systems I have worked on for 15 years now. Same problems.

1. Electricity can be produced without coal and oil
2. we just need batteries that can store them without much energy loss.
2. we just need batteries that can store them without much energy loss.
1. WOW. Really?
What they are waiting?
Explain, where is the profit if any of wind mill is about $ 3-4 million?
In 2015, the United States generated about 4 trillion kilowatthours of electricity.1
About 67% of the electricity generated was from fossil fuels (coal, natural gas, and petroleum).
Major energy sources and percent share of total U.S. electricity generation in 2015:1
Coal = 33%
Natural gas = 33%
Nuclear = 20%
Hydropower = 6%
Other renewables = 7%
Biomass = 1.6%
Geothermal = 0.4%
Solar = 0.6%
Wind = 4.7%
Petroleum = 1%
Other gases = <1%
