Cylindrical Battery Charging and Discharging Machine for 18650
Model:AOT-BFG256-5V10A
1. Equipment Function Introduction
This battery charging and discharging testing system is used for 18650 lithium battery capacity grading. The equipment is mainly composed of an automatic clamping mechanism, a clamp and a plate body for clamps placing, as well as the control circuit board installed in the cabinet, charging and discharging constant current and constant voltage testing board, drive switching power supply, etc.; the device itself can be operated independently, or can be controlled by an external computer.
