Electric vehicle battery swelling into balloons - Five Big Truths and Precautions

Generally speaking, when consumers buy power batteries, they can directly understand the function of the product from the name of the battery, and ignore its maintenance to prolong its life! There are more and more battery bulges in electric vehicles. In the face of this phenomenon, today we will reveal the "true face" of battery bulges and put forward corresponding solutions.


Tear off the true face of No. 1

As soon as the electric car stops, it charges immediately. When the electric vehicle is riding, the battery itself will heat up, and the temperature of the battery can even be as high as 70°C. If the battery has not cooled down, charging the electric vehicle as soon as it stops will increase the water loss of the battery and reduce the temperature of the battery. The service life of the battery increases the risk of battery charging.

Solution: charge after 30 minutes

Park the electric vehicle for more than half an hour, and charge the battery after the battery has cooled down sufficiently.

Tear off the true face of No. 2

If it is summer, the ultraviolet rays are particularly strong and the temperature is high, so it is not suitable for charging at this time. Especially under sunlight exposure, the battery will also heat up during charging. If it is charged under direct sunlight, it will also cause the battery to lose water and cause the battery to bulge. This will not only reduce battery life but may also cause electric vehicles to spontaneously ignite and explode.

Treatment method: charge in the shade

Try to charge the battery in the shade or choose to charge the electric car in the evening.

When charging, whether the internal or external temperature of the battery is high, the battery will lose water faster and shorten the battery life.

Tear off the true face of No. 3

At present, the popularity of the electric vehicle market naturally drives the prosperity of related supporting industries, especially the charger accessories market. At present, the electric vehicle market is flooded with a large number of inferior chargers. In addition, consumers have little awareness of the hazards of off-brand chargers and are greedy for cheap, so they often use off-brand chargers to charge their cars. Therefore, the problems that often arise are: the battery does not turn on when it is fully charged, and the charging current cannot be adjusted according to the battery current, resulting in overcharging the battery. After multiple overcharging, the battery will appear bulging. Special attention should be paid to the poor quality of electronic components and other materials of non-brand chargers, which are easy to wear and tear, which can easily lead to unstable current during charging, and no guarantee of automatic power-off, which is extremely harmful to battery life.

Solution: matching professional brand charger

It is recommended to go to a professional electric vehicle after-sales repair shop to replace a high-quality brand charger to ensure the charging quality and prolong the battery life.

Tear off the true face of No. 4

For the sake of convenience, many electric vehicle users often charge all night. The charging time not only exceeds 8 hours to 12 hours, but sometimes even forgets to cut off the power supply and the charging time exceeds 20 hours. This will inevitably cause great damage to the battery. This repeated overcharging for a long time can easily cause the battery to bulge and deform due to overcharging. Not only will it reduce battery life, but it will also cause the charger to burn out due to overheating.

Solution: 8-hour charging Control a reasonable charging time of 8 hours, avoid charging overnight.

Tear off the true face of No. 5

Frequent use of fast charging stations to recharge the battery. Now, there are a large number of fast charging stations distributed in many cities, which have indeed brought a lot of convenience to our lives, but fast charging stations are used for emergency charging, which is a short-term high-current supplementary power, and must not be used for a long time, otherwise, This will lead to battery degassing and severe water loss. Long-term use will easily lead to battery bulging, which will cause great damage to the battery.

Solution: try not to use fast charging

Try not to use the fast charging station if you can! Charge it at home first.
