The ACEY-BCT503R-512H is an energy-feedback lithium-ion cell grading machine specifically engineered for capacity grading and performance testing of lithium cells. Incorporating an energy feedback system, it returns energy from discharged cells to the power grid, thereby substantially reducing energy consumption. The cabinet is characterized by high precision and stable operation and is widely employed in cell manufacturing plants, battery pack assembly facilities, and research institutions.
When charging, the bidirectional power supply turns AC into 12V DC, and the constant current boards manage and monitor battery charging. When discharging, the process runs in reverse: the constant current boards boost the battery voltage to 12V, then the bidirectional power supply converts the DC back into AC and feeds it straight into the facility's AC distribution network, allowing energy from discharged batteries to be recovered.
