48-V Traction Battery — More than a Matter of Cell Configuration

Abstract

In contrast to the current trend to higher DC voltages in BEVs (400 V to 800 V), the new and innovative electrical drive system ISCAD (Intelligent Stator CAge Drive) is based on a voltage level of 48 V. ISCAD is being developed at the FEAAM GmbH in cooperation with the Universität der Bundeswehr in Munich. A reduction of more than 20 % of energy demand in a driving cycle is simulated in comparison to a reference vehicle.
