Maintenance of electric vehicle batteries is essential to extend battery life and maintain good performance of electric vehicles. Here are several common methods for maintaining electric vehicle batteries:
1. Use a suitable charger
A good battery needs to be paired with a suitable charger to perform at its best. Do not replace the charger at will, because chargers from different manufacturers may have different personalized needs. If you need to equip multiple chargers, it is recommended to use a supplementary charger during the day and the original charger at night.
2. Pay attention to the charging environment
Try to charge the battery in a cool, ventilated and dry place. Avoid direct sunlight or rain, as these factors will have an adverse effect on the performance of the battery and charger. When charging, connect the battery end first, then plug in the mains; after charging is completed, unplug the mains first, then unplug the battery end to avoid possible hydrogen explosion in the power box.
3. Control the depth of discharge
Avoid deep discharge of the battery (riding until the system is forced to power off) or too shallow discharge (riding only 1-2Km). The battery performance is best when charging when 70% of the battery power is used up. Long-term deep discharge or shallow discharge will affect battery performance.
4. Regularly perform deep discharge
A deep discharge can be performed every 2 months or so. The method is to ride until the power is forced off, turn off the power, ride home manually, and then fully charge the battery (the charger lights up green for 3 hours). Deep discharge should not be too frequent, otherwise the effect will be poor.
5. Avoid long-term storage with insufficient power
The battery should be fully charged in time after it is used up. Long-term storage with insufficient power or use before it is fully charged will affect the battery performance. After the charger lights up green, continue charging for another 3 hours for the best battery effect.
6. Protect the charger
To extend the life of the charger, avoid placing the charger in the trunk and basket of the electric bicycle. If it must be moved, it is recommended to wrap it with foam plastic to prevent vibration and bumps. Keep the charger ventilated during charging, otherwise it may affect the charging state and damage the battery.
7. Charge every day
Even if the endurance requirement is not long, it is recommended to charge every day to keep the battery in a shallow cycle state, which can extend the battery life. The memory effect of lead-acid batteries is not strong, and frequent full discharge has a greater impact on battery life.
8. Timely charging
After the battery is discharged, it should be charged as soon as possible to remove minor sulfidation. If it is not charged in time, the sulfidation crystals will aggregate into coarse crystals, and general chargers can do nothing about it, which will lead to a decrease in battery capacity and shorten the battery life.
9. Control the use temperature
The ideal operating temperature of electric vehicle batteries is generally around 25℃. When using electric vehicles in high temperature environments, you should avoid long-term continuous driving, stop and rest appropriately, and let the battery cool down. In low temperature environments, the activity of the battery will decrease, and the cruising range may be affected. At this time, appropriate warming measures can be taken, such as using a warming cover.
10. Regular inspection and maintenance
Regularly check whether the battery connection wires are loose, corroded, and whether the shell is damaged. If problems are found, they should be dealt with in time to ensure the safety and performance of the battery.
The above methods can effectively extend the service life of electric vehicle batteries and maintain the good performance of electric vehicles.
