How to maintain lithium ion batteries

1. When the storage period of the battery system exceeds 3 months, it should be stored at a state of charge of 50%-80%. 2. After 6 months of normal use of the power product, the following inspections should be performed during maintenance of the lithium-ion battery. If any malfunction is found, it should be eliminated immediately. Whether the bolts and nuts of various fasteners are loose. Whether the connecting lines between the packages are loose. Whether the various wiring harnesses are scratched, and whether the metal parts are exposed. 3. When not in use for a long time, it is recommended to perform charging and discharging maintenance every 12 months or so. The common methods for maintaining lithium-ion batteries are as follows: at an ambient temperature of 20±5°C, discharge at 0.2C first, put it aside for 30 minutes, and then charge The machine is fully charged. 4. During the maintenance process, please do not re-disassemble the battery in the battery pack by yourself, otherwise it will cause degradation of battery performance or damage to the battery. Lithium-ion battery maintenance 1. The output connection of the entire battery system of the battery pack must be completed by professionals. During the maintenance and assembly of lithium-ion batteries, care should be taken not to touch the battery pack and the positive and negative terminals of each battery pack with your hands or other metal objects at the same time to avoid electric shock or short circuit. 2. The fixing of the battery pack and the connection between the accessories should be firm and reliable. The battery pack should be prevented from working in an upside-down state. 3. When the power product leaves the factory, its SOC is about 50-80%. 4. The ambient temperature has a great influence on the discharge performance of the battery. The discharge capacity will decrease at low temperatures, which is a normal phenomenon and will recover at room temperature.
