For office workers, electric vehicles are a very easy and convenient means of transportation. In the case of traffic jams during peak hours, electric vehicles can quickly reach their destinations. For electric vehicles, the higher failure rate is usually the battery problem. When repairing and replacing, it can be found that there will be very obvious burn marks on the old battery, which may be caused by long-term use in a high temperature environment.
It is very easy for electric vehicle manufacturers to avoid this situation in advance. Adding a thermal protector can effectively solve this problem. The most feared problem of electric vehicle batteries is overcharging. Overcharging will cause the battery temperature to become too high. A bulging phenomenon occurs, and severe cases may cause the battery to explode and cause a fire. The principle of the thermal protector: when the temperature is too high, the circuit will be opened and the battery will not be charged until the temperature returns to normal, the thermal protector is closed, the circuit is energized again, and the battery starts to charge. When installing the thermal protector, it should be close to the battery, which can better sense the temperature and disconnect more quickly. The addition of a thermal protector to the battery can not only protect the safety of the battery, but also increase the battery life.
