What are the maintenance methods for lithium battery packs

Choose a suitable charger: Choose a charger with matching power, which can make the charging of the lithium battery pack more stable and not prone to accidents. Don't overcharge: Lithium battery packs have no memory effect. Do not overcharge to activate the battery, and do not overcharge to memorize the maximum capacity of the battery. Although most chargers of lithium battery packs have charging protection or guarantee in this respect, it is more conducive to the extension of the life of the lithium battery to develop a good charging habit just in case. (2) In terms of discharging, in addition to not overcharging, excessive discharging is also undesirable. Since a certain amount of lithium ions must be maintained in the negative electrode to maintain the stability of the structure, over-discharge causes more lithium ions to migrate out, destroying the stable structure of the negative electrode and causing irreversible damage to the negative electrode. (3) Operating temperature environment Charging environment temperature: The best charging environment for lithium batteries is 5 to 45 degrees Celsius. Although 0 to 5 degrees Celsius can still be charged normally, the charging current must be relatively reduced (5 to 45 degrees Celsius environment) to maximize battery life. Charging at high temperature or above 45 degrees Celsius will reduce battery performance and even degrade the electrolyte in the battery. Low temperature or below 0 degrees Celsius will cause internal resistance to increase, resulting in prolonged charging time. In addition, when charging in an environment below 0 degrees Celsius, the battery will be in a sub-freeze condition, which will cause irreversible damage to the battery. Discharge environment temperature: The discharge environment temperature of the lithium battery pack is generally -20℃~60℃, but generally below 0℃, the performance of the lithium battery will be reduced, and the discharge capacity will be reduced accordingly, so the full operating temperature of the lithium battery performance, It is usually 0~40℃. Some specially customized lithium batteries have different temperatures, and some can even run normally in an environment of hundreds of degrees Celsius. (4) Storage and maintenance Lithium batteries can be stored in a clean, dry and ventilated environment with a temperature of -5～35℃ and a relative humidity of not more than 75%. They should be alert to contact with corrosive substances, keep away from fire and heat sources, and do not store them. Do not disassemble the battery in direct sunlight. If the battery is stored for a long time, the battery power should maintain 30% to 50% of the nominal capacity. It is recommended that the stored battery be charged every 6 months. (5) Do not mix the battery with metal objects in the lithium battery pack, so as to prevent the metal objects from touching the positive and negative electrodes of the battery, causing a short circuit, damaging the battery or even causing danger. (6) Do not knock, acupuncture, step on, modify, or expose the battery to the lithium battery, and do not place the battery in a microwave or high-voltage environment. (7) Use a regular matching lithium battery charger to charge the battery, do not use inferior or other types of battery chargers to charge the lithium battery.
