The 48 Volt Eco Drive System has been developed for cost-efficient mass hybridization. Powertrain electrification below the safety-relevant 60 volt level is far less expensive compared to high voltage hybridization – and yet highly efficient. As a core component, the BMS is integrated into the battery and manages all functions of the 48 Volt Li-Ion battery. Based on collected battery data, the cells are individually balanced and operated under safe conditions.
