When the electric bike market is becoming more and more common, many people do not understand the correct charging method of electric bike lithium batteries. Now lithium battery pack is the first choice for electric vehicles, lead-acid batteries are bulkier in performance, the lithium battery pack is lighter, lithium battery performance is also more excellent, minus 20 ℃ to 55 ℃ can be charged and discharged normally, life is more lead-acid battery life of 3 to 4 times.
Electric vehicle lithium battery pack charging method
Follow the standard time and procedure for charging, even for the first three times.
When the electric car driving process of lithium battery pack low battery prompt, should be as soon as possible and timely charge the lithium battery.
Lithium battery electric car activation does not require a special method, the lithium battery pack will be activated naturally during the electric car driving.
Use the car with a special charger for charging, first the charger output plug corresponding to insert the battery charging socket, and then the charger plug into the utility jack, observe the indicator for charging determination.
After the charger indicator light turns green and then charge for 1-2 hours or so, you can stop the charging work.
Electric vehicle lithium battery pack correct charging tips
1. The battery does not need to be "activated"
The Li-ion battery pack does not need to be charged for more than 12 hours in the first three times, the Li-ion battery has no memory.
2. Battery charging
Use the charger specified by the manufacturer to charge, and pay attention to whether the charger model matches the battery model when charging.
3. Avoid high-temperature charging
Do not charge the lithium battery in an environment where the temperature exceeds 40 °, high temperature will make the battery capacity decline.
4. Charge in time
Try to implement the lithium battery pack with the use of charging, to avoid the battery each time after under-voltage charging, which can greatly enhance the battery life.
Long-term non-use of electric car lithium battery should be disconnected from the battery and the whole car, and intervals to the battery to replenish some power, to avoid self-discharge of the battery, or protection plate power consumption will be the over-discharged battery.
What should I pay attention to when charging an electric car lithium battery pack?
1. Place the rechargeable battery
The Li-ion battery pack has some power left before it leaves the factory, and it can also be ridden for a short distance after the electric car is 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, and the lithium battery pack should be charged in time after use without losing power storage.
2. Notes on the charger
To ensure the safety of the electric car lithium battery pack charging and to ensure the service life of the battery pack, the battery pack uses the matching lithium special charger. If the charger is lost or damaged, please find the corresponding dealer to buy. Do not use lead-acid chargers or other forms of chargers for charging.
3. Do not casually replace the charger, do not remove the speed limit of the controller
Each manufacturer's charger generally has individual requirements, do not change the charger at will when you are not sure. If the range requirement is long, it is necessary to equip multiple chargers for off-site charging and to adopt another supplementary charger for daytime top-up charging and the original charger for the evening. Removing the speed limit of the controller, although it can improve the speed of some cars, in addition to reducing the safety of the car, it will also reduce the service life of the battery.
4. Timely charging
After the battery is discharged, it starts the sulfation process, and at the beginning of 12 hours, there is obvious sulfation. Timely charging can clear the not serious sulfide, if not timely charging, these sulfide crystals will accumulate and gradually form coarse crystals, so, in addition to daily charging, but also pay attention to, after use to charge as early as possible, as far as possible to make the lithium battery pack power in a full state.
5. Pay attention to the charging environment
The best ambient temperature for charging is 25℃. Now most chargers do not have an automatic control system to adapt to the ambient temperature, so most chargers are designed according to the ambient temperature of 25 ℃, so it is better to charge at 25 ℃.
