What are the maintenance methods for lithium batteries of electric vehicles?

1. 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. Do not change the charger at will when you are not sure. If the mileage requirement is relatively long, it must be When charging in different places and equipped with multiple chargers, the charger that is supplemented for charging during the day uses a supplementary charger, and the original charger is used at night. Remove the speed limit of the controller, although the speed of some cars can be increased, except that it will reduce In addition to the safety of the car, it will also reduce the service life of the battery. 2. Protect the charger. The general instruction manual has instructions on protecting the charger. Many users do not have the habit of reading the manual, and often think of looking for the manual after the problem. It is often too late, so read the manual first. Very necessary. In order to reduce costs, the current chargers are basically not designed with high vibration resistance. In this way, the chargers are generally not placed in the trunk and basket of the electric bicycle. Under special circumstances, they must be moved. The charger should be packed in foam to prevent vibration and bumps. After many chargers are vibrated, their internal potentiometer will drift, causing the entire parameter to drift, resulting in abnormal charging status. In addition, it should be noted that when charging Keep the charger ventilated, otherwise it will not only affect the life of the charger, but also may cause thermal drift and affect the charging state. This will damage the battery. Therefore, it is very important to protect the charger. 3. Charge it every day. Even if your battery life is not long, you can use it for 2 to 3 days with a single charge, but it is still recommended that you charge it every day, so that the battery is in a shallow cycle state, and the battery life will be prolonged. Some early days Mobile phone users think that it is best to charge the battery after it is basically used up. This view is wrong. The memory benefit of lead-acid batteries is not that strong. Frequent discharge of electricity has a greater impact on the life of the battery. Most chargers change the indicator light After the light indicates that it is fully charged, the battery charge may be 97% to 99%. Although only 1% to 3% of the battery is under-charged, the impact on the ability to continue running is almost negligible, but it will also form under-charge accumulation, so the battery After the lamp is fully charged, it is better to continue floating charge as much as possible, which is also good for suppressing battery vulcanization. 4. Charge in time. After the battery is discharged, the vulcanization process begins. After 12 hours, obvious vulcanization appears. Charge in time, you can remove non-serious vulcanization. If you do not charge in time, these vulcanized crystals will accumulate and gradually form coarse The crystallization of the general charger is powerless to these coarse crystals, which will gradually cause a decrease in battery capacity and shorten the service life of the battery. Therefore, in addition to daily charging, it is also necessary to pay attention to charging as soon as possible after use. Make the battery full as much as possible. 5. Regular deep discharge. A regular deep discharge of the battery is also beneficial to activate the battery, which can slightly increase the capacity of the battery. The general method is to perform a full discharge on the battery on a regular basis. The method of full discharge is the condition of normal load on a flat road Ride down to the first under-voltage protection. Note that we especially emphasize the first under-voltage protection. After the first under-voltage protection of the battery, after a period of time, the voltage will rise and return to non-under-voltage. Status, at this time, if the battery is used again, the damage to the battery will be great. After the complete discharge is completed, the battery is fully charged. You will feel that the battery capacity has increased. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
