48V 30AH Long Cycle Life Elecric Bicycle Ebike Lifepo4 Battery Pack

Many businesses in the electric vehicle industry can clearly feel that the weather is hotter and the battery is more swollen than in other seasons. At present, many battery manufacturers have strengthened the standards of after-sales service, and the battery bulge is facing downgrade or even no after-sales service. So, what are the causes of battery bulging caused by hot weather, and how to avoid it?

Through the battery professional and technical personnel, we learned that there are many reasons for the battery bulging caused by the hot weather, of which 60% are mainly caused by the following three points:

1. The electric vehicle charger is exposed to high temperature to charge the battery, and the charger parameters drift.

When the weather gets hot, many electric vehicle users do not notice the cooling of the charger when charging the battery, and when the charger charges the battery, it heats up, and if it is exposed to high temperatures, it is easy to cause the charger parameters to drift. When the battery is fully charged, the charger with parameter drift can not turn the light in time, and the battery is still charging, and after many times, the battery is naturally easy to charge.

2. Charge the battery as soon as the electric vehicle stops, and the battery has not had time to cool down.

In the state of riding, the battery itself will heat up, coupled with the hot weather, the temperature of the battery can even reach more than 70 °C, at this time charging the battery will aggravate the water loss of the battery, reduce the service life of the battery, and exacerbate the risk of battery drumming.

3. Charge the battery under the condition of direct sunlight, which aggravates the water loss of the battery.

The battery also heats up during charging, and if it is charged in direct sunlight, it will also cause the battery to lose water, causing damage to the battery, which in turn will cause bulging.

When the weather gets hot, try to charge your electric car in the shade or in the evening. At present, battery manufacturers on the battery bulging punishment is relatively large, once the battery bulging may face price reduction penalties, usually in the sale of electric vehicles and battery replacement, more to give customers a reminder, but also to reduce their own trouble.
