What are the issues that need to be paid attention to in the power battery pack?

The following issues need to be paid attention to during the use of the power battery pack:

1. Charging

Choose a suitable charger

Be sure to use a regular charger that matches the power battery pack. Different models of battery packs may require chargers of different specifications. Using an unmatched charger may damage the battery or even cause a safety accident.

For example, fast charging chargers and slow charging chargers cannot be mixed, otherwise the battery life and performance may be affected.

Control the charging environment

When charging, choose a well-ventilated, dry, and temperature-appropriate environment. Charging in a high temperature environment may cause the battery to overheat and reduce the battery life; charging in a low temperature environment may affect the charging speed and battery capacity.

Generally speaking, the appropriate charging temperature is between 10℃-30℃.

Avoid overcharging

Do not overcharge for a long time. When the battery is fully charged, the charger should be unplugged in time. Overcharging will increase the internal pressure of the battery, which may cause the battery to bulge, leak, or even catch fire and explode.

Now many electric vehicles have intelligent charging management systems that can effectively prevent overcharging, but you still need to pay attention to the charging time.

2. Discharge

Avoid deep discharge

Try to avoid charging after the battery is completely exhausted. Deep discharge will cause irreversible damage to the battery and reduce the battery capacity and life.

It is generally recommended to charge when the battery has 20%-30% remaining.

Control discharge current

Avoid long-term high-current discharge, such as sudden acceleration, high-speed driving, etc. High-current discharge will increase the internal temperature of the battery and accelerate battery aging.

When using electric vehicles, the speed should be reasonably controlled to avoid frequent sudden acceleration and sudden braking.

3. Storage

Maintain appropriate power storage

If the power battery pack is not used for a long time, the battery power should be kept at about 50%-60%, and the battery should be charged and maintained regularly.

Excessively low or excessive power storage may cause damage to the battery.

Storage environment requirements

When storing battery packs, choose a dry, cool, ventilated place to avoid direct sunlight and high temperature and humidity.

At the same time, stay away from flammable, explosive items and corrosive substances.

IV. Maintenance

Regular inspection

Check the power battery pack regularly, including whether the appearance is damaged, whether the connection is loose, whether the battery capacity is reduced, etc.

If any problems are found, they should be dealt with in time to avoid the problem from expanding.

Cleaning and maintenance

Keep the battery pack clean to prevent dust, oil and other impurities from entering the battery. You can use a clean damp cloth to wipe the surface of the battery, but do not rinse it directly with water.

Professional maintenance

If the battery pack fails, you should contact professional maintenance personnel for inspection in time. Do not disassemble or repair the battery pack by yourself to avoid safety accidents.
