It is normal not to use the fuse in the battery box of the electric vehicle, but do not charge it. The charging current is large and the battery circuit will be hot and easy to burn, so when installing the battery, use thicker wires.
The fuse is installed in the battery to prevent excessive current and protect the circuit!
This has something to do with the fact that the electric car battery does not have a fuse.
1. The battery interface is exposed. If the interface is short-circuited by foreign objects. Or the wire connected to the battery box may wear out over time and cause a short circuit. Without insurance protection, the battery will be short-circuited and discharged. It's very dangerous. This may cause the battery to overheat or the wire to overheat. In severe cases, wires may be burned, the battery may be damaged or even take fhad and the battery may explode.
2. The fuse acts as insurance. There may be a short circuit when used in rainy days. At this time, the fuse has the function of protecting the battery and preventing damage or fire.
Yes.
Since lithium batteries are made of materials that prevent them from charging and discharging, overcharging, short-circuiting, and charging and discharging at temperatures Ultra-high, lithium iron phosphate batteries are always accompanied by a delicate protection plate and a current fuse.
Fuse, also called current fuse, is defined as a fuse that primarily functions as overload protection.
