Will the electric car battery explode?

Recently, the explosion of Samsung note7 mobile phone batteries has caused panic. Even small batteries can explode. Will the large batteries in our electric cars explode? 　　 Most of the electric car batteries on the market now use lead-acid batteries. It is the battery that people often say. This is the safest battery in the world, and it will not burn even if you use a lighter. So why does the battery self-ignite and explode? The main reasons are as follows: 　　 One, the battery cable is not firmly connected, and the connection point is not protected after being connected, causing fire or fire or explosion.　　 2. The battery connection line does not meet the requirements for use and causes fire or explosion. For example, the connection line is too thin to meet the charging and discharging current requirements, and there is no high temperature protection or wear protection on the surface of the connection line.　　 3. When installing the connecting wire, no protection measures were taken to isolate it from the car body frame, causing the connecting wire to wear out and cause fire or explosion.　　 Fourth, the battery installation box is too sealed, causing the explosion of the battery charging and discharging gas can not be discharged, causing fire or explosion.　　 5. Fire or explosion caused by malfunction of charging equipment.　　 6. Fire or explosion caused by the user's own home wiring problems.　　 Seven. Fire or explosion caused by charging in a high temperature environment or a closed environment.　　 It can be seen that as long as our electric vehicle batteries are used without problems, they will not become an untimely bomb like Samsung Note7. You can use them with confidence. Prev: Tips for battery maintenance of electric vehicles
