Hyundai Group announced that it will purchase approximately US$2.1 billion for the electric shaft drive system from German supplier Vitesco, which is expected to be used in the Group's new B- and C-class electric vehicles, using an electrical specification of 400 volts/160kW, which is different from the existing E-GMP platform, so it is speculated that it will be used in new, small, and affordable electric vehicles.
The electric shaft drive system supplied by Vitesco, codenamed EMR4, is the 4th generation of Vitesco's product, which integrates the electric motor, electronic control, and single-speed transmission (used as a reducer) into a single assembly system, which can reduce the installation space, which can be more conducive to the use of space for car manufacturers, and at the same time simplify the complex configuration of the power system.
According to Vitesco, EMR4 uses a new generation of SiC silicon carbide power semiconductor process, with the advantages of smaller size, higher power, higher heat resistance and other advantages; benefiting from the relationship of volume reduction, the new EMR4 assembly can be modularized, customized design, can be installed in different styles of electric vehicles, in addition to simplifying the design difficulty of electric vehicles, but also can further reduce the manufacturing and assembly costs of electric vehicles.
From hyundai's procurement of emr4 specifications: 400V/160kW version analysis, it is speculated that it should be an affordable, small electric model, and different from the existing E-GMP platform, or a derivative version of E-GMP, the car grid setting will be B level and C level size.
