First, the quality of charger. At present, there is a large amount of cheap and inferior chargers in the electric vehicle market. Some miscellaneous cards or assembled electric vehicles are usually equipped with such chargers for reducing production costs.

Many users do not understand the quality of the charger, they will buy this inferior charger. The electronic components of this inferior charger typically use inferior materials, which is easy to damage. It often occurs phenomena that is full of not skipping.

It cannot adjust the current size according to the charging state of the battery, resulting in a large number of batteries, often overcharge Result in battery drum bag. Inferior chargers account for about 70% in the cause of the battery. Second, the problem of charging time.

The average charging time of electric vehicle battery is 6-8 hours, and many electric car users are often charged all night, and the charging time is more than 12 hours. Some users must cause the battery because of forgetting, charging time or even more than 20 hours. Great damage.

The factors of the charging time have taken to 10% in the factors of the battery drum bag. Third, the matching problem of charger. Many families have two or more electric vehicles, and these electric vehicles are usually different brands.

The battery model is different. The charger cannot be universal, but some users will be mixed during use, take 72V charging. The charger 60V battery, take 20AH charger charge 12AH battery, the charging voltage does not match the current, will cause the battery to overtake, long-term over charge will result in battery drum bag.

The matching problem of the charger causes the factors of the battery drum to account for about 10%. Fourth, often use fast charging station charging. Now, there are a large number of fast charging stations, and the high current charging mode supplied by the fast charging station will cause the battery to be severely lost, and the long-term use can also cause the battery drum bag.

The factors that use the fast charging station to charge the battery drums account for about 5%. V. Quality of batteries.

The quality cause of the battery can also cause the battery to be drummed. If it is a brand new battery, this situation rarely occurs, accounting for about 5% of the normal drum, so that the proportion of drums caused by battery quality causes very little However, no matter what causes caused by the battery, in the end, it is often a battery back. Some batteries that use drums in half a year, according to the possibility of 99% of the relevant experience, is not caused by battery quality problems.

As the industrial product for the after-sales service, there is a problem. Whether it is a battery that is drumming or running, it is a problem that the electric car battery may encounter during use. We should have a good attitude.

The battery is the core parts of electric vehicles, and the battery drums this word. I believe that the riders are not strange. In recent years, the phenomenon of battery drums is not uncommon, so many consumers are very troublesome.

Because once individual battery drums occur in a set of batteries, replace the entire set of batteries. Today's topic is in the battery drum bag. First of all, let's explain the electric car battery drum bag first.

There are more or less hydrogen when the battery is charged, so even if a fully enclosed battery often has a stitch, let hydrogen discharge. When the stamp is not sent, the hydrogen that occurs will be, the more accumulated, and finally the battery shell. This is the battery drum we often say.

Battery after drums, more dangerous, generally not recommended to continue. 1. Electric vehicle charger is exposed to battery charge, charger parameter drift.

In the summer, there is no high temperature in the summer. Many electric vehicles are charged in the summer. When charging the battery, the cooling of the charger is not noticed.

When the charger is charged to the battery, it is fever, if it is exposed to high temperatures, it is easy to cause the charger parameter drift. In particular, some of the quality of the charger, the case where the parameter drift in high temperature is more common. When the battery is already fully charged, the charger of the parameter drift cannot be turned in time, and it is still charged the battery, after many times, Battery is naturally easy to charge.

2, electric car stops to charge the battery, battery is not ready to cool down. The electric vehicle is in a riding state, the battery itself will fever, plus the weather hot, the temperature of the battery can even reach 70 ¡ã C, at this time, the battery is charged to exacerbate the downtime, reduce the battery life, intensify Battery drum risk. 3, charge the battery under the conditions of direct sunlight, plus the battery is lost.

The battery will also heat during the charging process, if charging in direct sunlight, can cause the battery to lose water, causing damage to the battery, thereby causing drum bag.
