5V 3A 512 Channels Energy-feedback Lithium Ion Cell Grading Machine for 18650 21700 26650 32700
Product Description
ACEY-BCT503R-512H energy-feedback lithium ion cell grading machine is specifically designed for lithium cell capacity grading and performance testing. Equipped with an energy feedback system, it recycles the energy from discharged cells back to the power grid, significantly reducing energy consumption. The cabinet features high precision and stable operation, and is widely used in cell manufacturing plants, battery pack assembly facilities, and research institutions.
Equipment Structure
Energy Feedback Function
During charging, the bidirectional power supply converts AC to 12V DC, and the constant current boards control and monitor the charging of the battery. During discharging, the process is reversed: the constant current boards first raise the battery voltage to 12V, and then the bidirectional power supply converts the DC back to AC, feeding it directly into the facility’s AC distribution network. This enables the recovery of energy from discharged batteries.
