Electric vehicle lithium battery pack charging method and charging precautions

When the electric vehicle market becomes more and more common, many people do not understand the correct charging method for electric vehicle lithium batteries. Lithium battery packs are now the first choice for electric vehicles. Lead-acid batteries are more bulky in terms of performance,lithium battery packs are lighter, and lithium batteries perform better. They can be charged and discharged normally at minus 20°C to 55°C, and their life is even more lead-acid. 3 to 4 times the battery life.

Charging method of lithium battery pack for electric vehicle

Charge according to the standard time and procedure, even the first three times.

When the lithium battery pack appears to be too low during the driving of the electric vehicle, the lithium battery should be charged as soon as possible.

Lithium battery electric vehicle activation does not require a special method, the lithium battery pack will naturally activate when the electric vehicle is driving.

To charge with a special charger for the car, first insert the output plug of the charger into the battery charging socket and then insert the charger plug into the mains socket. Observe the indicator light for charging judgment.

After the charger indicator turns green, charge it for about 1-2 hours to stop charging.

Tips for Correct Charging and Use of Lithium Battery Packs for Electric Vehicles

1. The battery does not need to be “activated”

The lithium battery pack does not need to be charged for more than 12 hours in the first three times, and the lithium battery has no memory.

2. Battery charging

Use the charger specified by the manufacturer to charge. When charging, pay attention to whether the charger model matches the battery model.

3. Avoid high temperature charging

Do not charge the lithium battery of an electric vehicle in an environment where the temperature exceeds 40°. High temperature will cause the battery capacity to decline.

4. Charge in time

Try to implement as much as possible for the lithium battery pack as it is used and recharged to avoid recharging after the battery is under-voltage every time, which can greatly improve the battery life.

5. Storage

When the lithium battery of an electric vehicle is not used for a long time, disconnect the battery from the vehicle, and add some power to the battery at intervals to avoid self-discharge of the battery or over-discharge of the battery due to the power consumption of the protection board.

What should I pay attention to when charging lithium battery packs for electric vehicles?

1. Place the power supply

Lithium battery packs have some remaining power before they leave the factory, and they can also be used for short-distance riding after electric vehicles are sold. After the first ride, the battery must be charged for the first time. It is recommended that the first charge should be carried out for a long time. The lithium battery pack should be charged in time after use and cannot be stored under power loss. If the battery has not been used for more than two months, The lithium battery pack needs to be fully charged.

2. Precautions for the charger

In order to ensure the safety of charging the lithium battery pack of electric vehicles and ensure the service life of the battery pack, the battery pack uses the supporting lithium battery charger. If the charger is lost or damaged, please buy it from the corresponding dealer. Do not use lead-acid chargers or other forms of chargers for charging.

3. Do not change the charger casually, and do not remove the speed limit of the controller

The chargers of various manufacturers generally have individual requirements. Don’t change the charger at will when you are not sure. If the continuation mileage is relatively long, it is necessary to equip multiple chargers for charging in different places. The chargers for supplementary charging in the daytime should be supplemented with chargers, and the original chargers should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but in addition to reducing the safety of the car, it will also reduce the service life of the battery.

4. Charge in time

The vulcanization process began after the battery was discharged, and obvious vulcanization appeared after 12 hours. Charging in time can remove non-serious sulfurization. If you do not charge in time, these sulfurized crystals will accumulate and gradually form coarse crystals. Therefore, in addition to daily charging, you must also pay attention to charge as soon as possible after use, and use lithium as much as possible. The battery pack is fully charged.

5. Pay attention to the charging environment

The best ambient temperature for charging is 25°C. At present, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25°C, so charging at 25°C is better.
