Electric wheelchair catches fire, experts urge to choose reputable batteries

Earlier, an electric wheelchair caught fire in Sau Mau Ping, Kwun Tong, and the electric wheelchair ended up with only its bracket burned out. Therefore, experts say that when purchasing an electric wheelchair, you must choose reputable and original lithium batteries. The following is a brief description of the difference in quality between reputable batteries and batteries from other unknown brands.

Electric wheelchair batteries should choose batteries with a good reputation

Reputable Batteries VS. Unknown Brand Batteries

High-quality lithium batteries generally have the following two characteristics:

1) Short circuit protection:

There are fuses in the circuit. When there is a fault in current or voltage, the fuse can help cut off the power immediately.

2) Overcurrent protection:

The overcurrent relay coil is connected in series to the protected circuit. When the current reaches the set value, the overcurrent relay operates to cut off the power of the contactor coil. The main contact of the contactor in the main circuit is disconnected, so that the motor power is cut off in time.

Although they are just two simple small configurations, they are the key points that matter for life.
Therefore, it is necessary to choose a reputable lithium battery
