Recently, battery explosions in the Samsung Galaxy Note7 phone have left people worried. If even such a small battery can explode, can the much larger battery on our electric vehicle explode too?

Most electric vehicle batteries on the market today use lead-acid batteries, which are what people commonly call batteries. This is the safest battery in the world; it will not catch fire even if you light it with a lighter. So why do batteries spontaneously ignite or explode? There are mainly the following reasons:

1. The battery connecting wires are not fastened firmly during connection, and no protective measure is applied at the connection points afterward, causing sparks, fire, or explosion.

2. The battery connecting wires do not meet usage requirements, causing fire or explosion, for example the wires being too thin to handle the charge and discharge current, or having no high-temperature or wear protection on the outside.

3. When installing the wires, no isolation protection is taken from the vehicle frame, so the wires are worn through and cause fire or explosion.

4. The battery box is sealed too tightly, so the gases produced during charging and discharging cannot be released, causing fire or explosion.

5. A fault in the charging equipment causes fire or explosion.

6. Problems with the user's own household wiring cause fire or explosion.

7. Charging in a high-temperature or enclosed environment causes fire or explosion.

From this we can see that, as long as it is used properly, our electric vehicle battery will not become a time bomb like the Samsung Galaxy Note7, so you can use it with confidence.
