18650 lithium-ion battery pack process quality characteristics
1. To select qualified high-quality lithium-ion batteries, qualified and stable suppliers must supply single batteries with excellent performance. The single batteries have passed a series of safety tests and functional tests and are qualified for use.
2. The internal resistance of the battery is required to be low and consistent. Whether it is a 14.8v lithium-ion battery pack or other energy storage battery packs, it is necessary to ensure low internal resistance, high-current discharge capacity, platform and heat dissipation.
3. The battery structure adopts a ventilation design, and the distance between two adjacent batteries is not less than 2mm. This construction requires the battery to be held in place by a plastic bracket.
4-pack battery factory uses slotted nickel plate in spot welding, the size of nickel plate is satisfied with the requirements of large current discharge, nickel plate data, to ensure low internal resistance, spot welding machine, to ensure stable work, welding pins, to ensure quality, operator training And after passing the test, check whether the solder joints are strong or not by spot welding. And carry out vibration test on each batch of products to verify its anti-vibration performance.
5. Make typical products of different batches of batteries and conduct life tests. While summarizing the relevant experience in the design of lithium-ion battery packs, cycle tests are carried out on battery products to obtain the actual cycle life.
6. Verify the high and low temperature function of the battery. Batteries from different packaging lithium-ion battery manufacturers were prepared and discharged at different discharge rates at high and low temperatures to obtain actual discharge curves.
