[0002] During the production process of lithium batteries, lithium batteries need to be continuously charged and discharged to test and adjust their performance. Existing cylindrical lithium-ion battery chargers and dischargers are generally split-type, dividing the equipment into a mechanism and a power supply part, which are placed separately and far apart. There are many problems such as large equipment space, large number of cables, low charging and discharging efficiency, and high cost. Although a few integrated charger and discharger mechanisms integrate the power supply part inside the needle bed, the overall height of the mechanism is not significantly improved compared to the split type. Each mechanism requires a separate pressing mechanism, and the overall size of the charger and discharger is still large, increasing the factory's energy consumption and space costs.
