Here are the links i was referring to: Guangzhou: 广州一辆Model S发生自燃，没有充电，也没有发生碰撞-锂电池-电池中国网 Shanghai (well known): Tesla spontaneously combusts in Shanghai parking garage Hong Kong: 【獨家】Tesla停車30分鐘後離奇自焚爆炸 車主逃過一劫 I have >20 fires while parking in my list. A Nio with NCM811 caught fire around that...

And condition "X" or "Y" neither?

It's about the way of thermal coupling between the cells. Has advantages and disadvantages. Imho the advantages weigh out the disadvantages. Statistic speaks for M3 on first sight too. Better support for longevity of the pack too. But we are OT. Could you please give condition "Z" a name that...

5 i've seen on pics/videos but was not able to find any further information in the web, respective information was removed after some time for some reason.

Model 3/Y battery pack has advanced thermal propagation protection that's true.

Sorry, circumstances. 105 of those should be commonly found in the web. But back to topic?

Just for statistics: I know about 110 Tesla fire incidents, which include all of these reasons: Fire when parked and not charging Fire when parked and connected to DC or AC charger Fire while driving Fire while transport by carrier (trailer or train) Fire while in repair shop Fire while at...

Every accident is different. The battery pack is a lot more vulnerable to cell damage when crashing with poles, trees, concrete barriers, etc. But you are right this is OT.

In a new cell there is always excess lithium, so the loss of capacity is not directly proportional to the loss of cycyleable lithium. How much excess lithium a manufacturer uses in a new cell is a question of the wished safety class, but also from the chosen electrode balancing.

No, the nail test is a standardized test which uses a steel needle to puncure the cell in order to provoke an onset.

Here a littlebit of statistics about Tesla 2016-18 Model X non crash or vandalism fires in relation to gas cars (100 ist the average of all observed cars):

All the mess with capping started with 3 fires in parking lots in China when Tesla was forced to react by chinese authorities.

Here the older evaluation of the Model S compared to a ZOE:

Concerning safety there are many things to consider, in Tesla's design some things are very good other good and other bad. Where you always start is the safety of the cathode raw material itself (chemical issue). Here a comparision of the eneregy release of different (partially outdated) raw...

This is a revaluation of the battery from a Model S, they inspected 2 years before. In this point (overcharging protection) Tesla and other manufacturers did a good job and the valuation got better. In general, european manufacturer stated a self commitment to not use hazard level > 4 components.
