Lithium battery manufacturers analyze how to properly maintain lithium battery packs

If lithium batteries are properly maintained, what are the maintenance methods? Lithium-ion battery packs are more and more widely used in various fields in today's era. Correct use and maintenance of lithium batteries are very important. After all, the price of lithium batteries is not cheap. Improper use will accelerate the aging speed of lithium batteries and even damage them. In severe cases, dangerous explosions and fires may occur. Maintenance method of lithium battery pack (1) Correctly charge and select a suitable lithium battery charger: Choose a charger with appropriate power to make lithium battery charging more stable and reduce accidents. It is possible to avoid overcharging completely: the lithium battery pack has no memory effect. Even if the capacity drops due to lag, it only needs to be used for a few times to restore to the original state. There is no need to overcharge to activate the lithium battery, and there is no need to overcharge. In order to restore the maximum capacity of the lithium battery. Although most lithium-ion battery chargers have charging maintenance or warranty, just in case, it is important to develop good charging habits, which is more conducive to the extension of lithium battery life. (2) In addition to not overcharging the lithium battery correctly, excessive discharging is also undesirable. Excessive deep discharge will cause accumulation of the negative electrode of the lithium battery, which will directly lose the battery's capacity. Under normal circumstances, it is best to choose charging when the lithium battery has 30% of its capacity left. (3) Suitable temperature environment Charging temperature: The best charging environment for lithium batteries is 5-45°C. Although 0 ~ 5℃ can still be charged normally, the charging current requirement is reduced (5 ~ 45℃ environment), which can maximize the battery life. Charging at a high temperature above 45 degrees Celsius will reduce the performance of the battery and even the electrolyte. Low temperature or below 0°C will increase the internal resistance, resulting in prolonged charging time. In addition, when the battery is charged below 0°C, the battery is in a sub-freezing state, which will cause irreversible damage to the battery. Discharge environment temperature: Lithium battery discharge environment temperature is generally -20℃~60℃, but generally below 0℃, the function of the lithium battery will decrease, and the discharge capacity will also decrease, so the function of the lithium battery is the full operating temperature, generally 0~40℃. Some specially designed lithium-ion batteries differ in temperature, and some can work at hundreds of degrees Celsius. (4) Storage and maintenance Lithium-ion batteries can be stored in a clean, dry and ventilated environment, with an ambient temperature of -5 ~ 35°C and a relative humidity of less than 75%. Avoid contact with corrosive substances, keep away from fire and heat sources, and avoid direct sunlight. If the battery is stored for a long time, the battery power should be 30% ~ 50% of the rated capacity. It is recommended to store and charge the battery every 6 months. (5) Lithium-ion battery packs must not mix the battery with metal objects, so as to prevent the metal objects from contacting the positive and negative electrodes of the battery, causing a short circuit, damaging the battery, or even causing danger. (6) Do not beat, acupuncture, torture, modify, solar cells, batteries in microwave, high voltage and other environments. (7) Use a suitable lithium battery charger to charge the battery. Do not use inferior or other types of battery chargers to charge the lithium battery. How to maintain lithium batteries? The above are the key points of lithium battery maintenance requirements. It is very effective to develop good lithium battery packaging habits to extend the life of lithium battery packaging. What we need is to meet our own needs for using lithium batteries. It is the key to extend the life of lithium batteries as much as possible. Lithium battery itself is a consumable, no matter what method we use, we cannot avoid its final loss, as long as we use the correct method to delay its aging.
