First, the battery charging time is too longThe time of electric vehicle charging cannot be too long. If you repeatedly charge it, it is easy to cause the battery to be charged because of overcharging. According to the actual research data, the charging time is too long, causing the battery to be drummed, accounting for about 15%.
Second, the charging current is too large
Long-term use of the speed charging station will also take the battery. Because the working principle of the fast charging station is the large current charging, which will cause the battery to be lost, and the battery drum is thrown.
Third, use different specifications chargers
If you use different specifications of the charger, the charger rated voltage and current will appear, do not match the battery, not only the battery is drum, but even the explosion.
Fourth, long-term charging in high temperature environments
The normal charging mode should be: depending on the battery power, the charger can be floated after 2 hours. If the ambient temperature is high, it is charged after the end of the riding. The correct way is to make the battery surface temperature naturally cool, then charge. Long-term charging in a high temperature environment can cause the battery to be drumped.
Fifth, using a damaged charger
The electronic components on the electric vehicle charger motherboard are welded, some large electronic components, bump vibrations may cause dewrapping, resulting in poor contact, causing current instability and protection function failure, resulting in a battery.
Sixth, use inferior chargers
Some consumers have the original charger to buy one, if you buy inferior products, the battery is hurt. This charger current is unstable, not strong, and long-term use of the battery will be drumped.
Seventh, continue to charge after the battery is damaged
Sometimes electric vehicles encounter a traffic accident, such as crash or fall, the battery has a quality under external force, and if you continue to charge such a battery, it will be charged.
Eighth, the battery itself is caused
Some consumers are cheap, buy inferior batteries. These inferior batteries are incadvenated in the production process, the acid is not enough, or it is refurbished or repaired, even if the above problems are eliminated, still the phenomenon, so choose a good battery. important.
Electric vehicle charging, please follow the two principles: The first develop a good charging habit; the second resolute does not buy inferior charger and battery. Of course, battery life is also related to electric vehicle performance, so buying electric vehicles can also buy cheap inferior vehicles.
