Consumers always find the problem of the merchant when there is a problem with the battery. In fact, in many cases, improper use is the biggest culprit.
In the process of use, which ones are likely to cause bulging?
# 1 Charging time is too long #
The charging time of an electric vehicle cannot be too long, usually 8-12 hours. If it is repeatedly charged for a long time, it is easy to cause the battery to be charged due to overcharging. The charging time is too long and the battery charging drum accounts for about 15%.
# 2 Too much charging current #
Long-term use of the fast charging station on the roadside will also charge the battery, because the working principle of the fast charging station is to charge the battery with a large current for a period of time, which will cause serious gassing and water loss of the battery, and the battery will bulge.
# 3 Random use of different specifications of charger batteries #
If chargers of different specifications are used indiscriminately, the rated voltage, voltage and current of the charger will not match the battery. Not only will the battery be charged, but it will even explode.
#4 Long-term charging in high temperature environment #
The normal charging mode should be: depending on the battery power. In summer, the charger should stop charging after turning the green light, and in winter, the charger can float for 3-4 hours after turning the green light. After the surface temperature of the battery cools naturally, charge it again to avoid charging in a high temperature environment.
# 5 Damaged charger #
The electronic components on the main board of the electric vehicle charger are welded. For some large electronic components, bumps and vibrations may cause desoldering, resulting in poor contact, resulting in unstable current during charging and failure of the protection function, causing the battery to be charged.
# 6 Inferior Charger #
Some consumers just buy one if the original charger is broken. If you buy a low-quality product, it will damage the battery. This kind of charger has unstable current and poor heat dissipation, and the battery will be charged after long-term use.
# 7 Continue to charge after the battery is damaged #
Sometimes an electric vehicle encounters a traffic accident, such as a crash or a fall, and the battery undergoes a qualitative change under the action of external force. If you continue to charge such a battery, it will also be charged.
# 8 The quality of the battery itself #
Some consumers are greedy for cheap and buy low-quality batteries. These inferior goods are not uniformly acidic or insufficient in the battery production process, or are originally refurbished or repaired. Even if the above problems are eliminated, the phenomenon of drum charging will still occur.
I hope everyone follows two principles when using batteries. First, develop a good charging habit; second, resolutely refrain from buying inferior chargers and batteries. I believe your battery life will be prolonged.
