Lithium-ion battery charging and discharging test cabinet is a kind of equipment used to test Li-ion batteries. It can simulate various working states of lithium battery during charging and discharging, and also test and evaluate the electrical performance of the battery.
AC/DC Bidirectional Power Supply
The equipment adopts energy-saving AC/DC bidirectional power supply, with high charging efficiency and feedback of battery discharge energy to the power grid.As shown in the above figure, a portion of the battery discharge energy is used internally by the power supply itself, another portion is used by other charging devices, and the remaining portion is fed back to the power grid for use by other devices.
