What are the reasons why the heat of the weather caused the battery drum pack, and how to avoid it?

Many companies in the electric car industry can clearly feel that the weather is turning hotter than other seasons. At present, many battery manufacturers will not face a downgrade even after the battery expands in order to strengthen after-sales service standards. So, what is it that hot weather causes battery expansion, and how to avoid it?

With the impact of batteries on professional technicians, the thermal battery expansion due to a variety of reasons, 60 % of the reasons are mainly the following three points:

Electric car charger exposed to high temperature to charge the battery, charger parameters drift.

When the weather gets hot, many electric car users do not notice the cooling of the charger when charging the battery. When the charger charges the battery itself, if it is exposed to high temperatures, especially some poor quality chargers, At high temperatures, this kind of parameter drift is more common. When the battery is full of electricity, the parameter drift charger will not become lighter, and the battery will be charged in time. After several times, the battery will be easily filled with drums.

The battery hasn't had time to cool as soon as the electric car stops to charge it.

In the cycle state, the battery itself will be hot, coupled with hot weather, the battery temperature can even reach 70 °C or more, and then recharging the battery will increase the loss of battery liquids, reduce the service life of the battery, and the risk of fuel cell operation. drum.

3, under the conditions of the sun to charge the battery, the fuel cell lost water.

Also during the charging process, if the sun shines directly, it will also cause the battery to lose water, causing damage to the battery and causing uplift.

When the weather gets hot, try to choose in the shade or at night when charging an electric car. Battery manufacturers are now penalizing battery expansion and may face a fine if the battery exceeds it. When the sales of electric vehicles and batteries change in normal times, be more careful with customers and reduce trouble.
