At present, most car companies adopted are ternary lithium batteries，Its battery life is long，High energy density，But the stability is worse，There are already many fire incidents of electric vehicles，It is more or less related to the battery，So the safety of the battery is also the top priority。

Of course there are waterproof measures for battery packs，There is also water dipping experiment when leaving the factory，According to the relevant regulations of the country，Battery waterproof level needs to reach IP67，That is, soak the battery in the water for 1 hour without leaking electric shock at room temperature。

That is to say，If there is water or heavy rain on the road，No problem，Otherwise, the vehicle will not be available。

There is also a saying "often walk by the river，How can there be no wet shoes "，Although there are waterproof measures，But it can’t mean that it has been soaked in the water。If the battery bag is soaked in water for a long time，It is also possible to have leakage，You need to leave seabet mythe car first，Clean the water in the battery pack, etc.，Do some leakage checks，Otherwise, there is a danger of electric shock。

 If the vehicle is soaked in the water，It is recommended not to start the car at will，It must be checked and handled by professional personnel，There are more circuits and circuits on the car，There is a large possibility of leakage after soaking water。
