What are the low temperature heating methods of lithium batteries?

　　The low temperature heating method of lithium batteries circulating on the market is mainly the following two chargers heating and protecting the protective board heating.

　　Charger heating

　　The first lithium battery heating method is to rely on special chargers for heating, because it cannot be charged normally in the low temperature environment. Relying on the charger to heat the battery, increase the temperature to zero to zero, and then charge the battery to charge the battery, and then charge the battery to charge the battery. Essence This method is a safer and effective method, but the time it takes is relatively long, because the charger in a low temperature environment can only perform small -rate discharge heating. Therefore, it takes about 1 to 3 hours to heat it before charging. This method is more suitable for a fixed place, such as a house where the Arctic has a house. At this time, using the charger to heat it can solve the problem of low temperature heating. The only problem is the charging time.

　　Protective board heating

　　The second lithium battery heating method is heated through the lithium battery protection board. There are two types of lithium battery protection boards: PCB and BMS. Both the battery can be controlled by heating, but the control heating of lithium battery can be divided into two methods.

　　1. Heat electric sheet heating

　　The low temperature heating method of this electric heating tablet is mainly pasted with the corresponding heating tablets on the side of the battery, and then the connection control is connected through the protective board. Pass the heat generated by the electric heating film directly to the battery, and as the temperature increases, the resistance increases, thereby achieving the purpose of autonomous temperature control. The overall technical content of this low temperature heating method can solve the problem of the moment.

　　2. Preheat the battery itself

　　What is more powerful in the low temperature heating method of this type of lithium battery is that in fact, the manufacturer specially reserves a part of the electricity that specializes in the battery when designing the battery to heat the battery itself, and it only needs to be reserved to heat up to stable. The overall technical content of the low temperature heating method of this lithium battery is high.
