Is the battery of a pure tram safe, for example, will it explode when it crashes?

The safety of pure electric vehicles cannot be compared with that of fuel vehicles, which is the most basic structural design problem.

All pure electric vehicles are equipped with battery packs on the chassis, but the current core technology ternary battery technology can not solve the problem of natural deflagration and explosion due to short circuit under external force, which is a common problem of all pure electric vehicles. Because there is no material that can ensure that the chassis will not be deformed or damaged as a stress structure in a car accident, the possibility of spontaneous combustion, deflagration and explosion of pure electric vehicles in a car accident is very high. Even Tesla can only use titanium alloy battery case to increase the strength of battery case at present, but spontaneous combustion happened. The core problem is that ternary battery technology can't cope with short circuit caused by external impact.

As for the total ban on the sale of fuel vehicles, at least until the middle of this century, it can only be said to be a pure joke. When a fuel vehicle is converted into a pure electric vehicle, it just jumps from one pit to another deeper pit. The battery industry is more polluted and more difficult to control, including air pollution, land pollution and water pollution. That is a false proposition of environmental protection. Moreover, the main way of power generation is coal burning, and each production of a pure electric vehicle is equivalent to the exhaust emissions of fuel vehicles for many years.
