Recently a fierce fire broke out in front of the stairwell of a residential building in Wuxi, Jiangsu. For a while thick smoke rolled through the building, and several e-bikes charging in front of it were burned out. Over-charging of an e-bike set the electrical box on fire, causing one death and one injury.

The special danger of e-bike fires shows in two points: the temperature of the fire and the toxic smoke. Data show that in three minutes the fire temperature can reach a thousand degrees, and in thirty seconds toxic gas fills the whole room. The smoke temperature can exceed 1000 degrees, and hot toxic smoke is deadlier than open flame.

The technicians at the Xupai battery after-sales repair station tell us that whether in heat or cold, e-bike spontaneous ignition is all too common, and unscientific use of an e-bike can easily cause it to catch fire.

1. Privately run and messy electrical wiring, wires that are too thin in cross-section, damaged insulation on power cords, missing short-circuit protection, and substandard power strips can all easily cause fires.

2. Alarm systems without protection and users who increase the electrical load on their own are common in real life. From missing alarm protection to unauthorized load increases, these are another important cause of fire; consumers are warned here that unauthorized modifications bring endless trouble.

3. Use a qualified charger. A qualified charger usually has an intelligent multi-stage charging mode, under-voltage and over-current protection circuits, and matches the battery of the e-bike, so it avoids over-charging, battery overload and high temperature, line short circuits, and battery overheating or explosion that could lead to fire.

4. Unreasonable battery wiring design and unreliable quality can be traced back to the e-bike manufacturer itself. So when choosing a battery, pick a high-quality brand with a good reputation, such as Xupai battery. Xupai batteries are very solid in quality with good service, and its sales, customer service, technical support, and repair systems are well developed, giving consumers better after-sales service.

5. Parts made of flammable or combustible materials. When parts are made of flammable materials, the circuit heats up most easily, reaches the ignition point, and then a fire breaks out. This usually appears on inferior and no-name e-bikes, so consumers only need to avoid these brands when buying.
