What are the causes of fire in power r03 battery?
As the energy source of pure electric vehicles, the main cause of fire in r03 battery is thermal runaway caused by overheating of the battery. This overheating is most likely to occur during the battery charging and discharging process. Since r03 battery have a certain internal resistance, a certain amount of heat will be generated while outputting electrical energy to provide power for pure electric vehicles, causing their own temperature to rise. When their own temperature exceeds their normal operating temperature range, it will damage the life and safety of the entire battery.
Causes of thermal runaway:
The first category is external factors of the battery. If the ambient temperature of the battery is too high, the battery does not dissipate heat well, or the internal winding is not good, resulting in poor heat dissipation of the battery. In addition, there is another situation that the company should pay special attention to, that is, the battery spine can sometimes introduce heat. The metal spine of the battery is made of copper and aluminum, and the thermal conductivity is relatively good. There are certain high-heat source components in the circuit, which must be kept away from the battery spine to allow the heat to fully play out. Qiu Xinping added.
The second category is internal factors of the battery. The first is micro short circuit. There are two types of micro short circuits. One is the short circuit in the battery process, including burrs; the other is the short circuit during use. These will cause micro short circuits, causing the local temperature of the battery to be higher than the thermal runaway temperature, resulting in thermal runaway.
The third is overcharging the battery. Overcharging will reduce the thermal runaway temperature of the material. For example, the capacity of the battery has decayed in the middle and late stages of use. At this time, the battery itself is already in an overcharged state, and the thermal runaway temperature will naturally drop. Qiu Xinping pointed out.
The fourth is the amount of electrolyte used. If the amount is too much, the explosion will be very harmful, and the flame will spray very high and far, so the amount of electrolyte used must be strictly controlled.
