The "Active Charger Transfer" technology actively "shovels" excess charge from one cell to another with virtually no loss. This weaker cells in the stack are actively supported and the entire battery can be optimally utilized. High balancing currents up to 5 A. Isolated communication to the String Management Controller (SMC) by CellCom at stack voltages up to 1,400 VDC. For all cell technologies up to 5 V / cell configurable.
