You have probably seen news about electric vehicle batteries catching fire. Most electric vehicle batteries on the market are lead-acid batteries, and a lead-acid battery does not catch fire on its own. So what causes the fire? Xupai takes a look.

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

2. The battery connecting wires do not meet usage requirements, causing fire, 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.

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

5. A fault in the charging equipment causes fire.

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

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

The above are the causes of electric vehicle battery fires. We hope this helps, and remember to guard against fires in daily use too!
