High voltage Automotive Electrification systems

December 2016, Valeo and Siemens decided to set up a joint venture under the name of Valeo Siemens eAutomotive to combine their know-how and increase their skills in developing high-voltage electrification solutions for all types of vehicles. This merger has enabled the two companies to extend their product and solution portfolio and to create synergies at the industrial level, particularly in the development of high voltage systems. In the automotive industry, high-voltage electricity refers to battery voltage above 60 Volts.

Valeo and Valeo Siemens eAutomotive produce a range of powertrain solutions for electrically powered vehicles that use electrical energy as their sole source of power, either they are hybrid or fully electric vehicles.

Electrification technologies to improve the range, performance and comfort of electric or hybrid vehicles (whether plug-in or not)

Via its participation in the Valeo Siemens eAutomotive joint venture, established in late 2016, Valeo is contributing to the growth of hybrid, plug-in hybrid and full electric vehicles by developing and industrializing the following powertrain as follows:

  • Electric motors and their power electronics (inverter) allowing the electric engine control.
  • Full high-voltage geared motor system (motor + inverter + reducer).
  • On-board battery charger integrating the option of DC voltage converter to supply the vehicle’s electrical system.

High voltage car battery for large vehicles and light cars

These high-voltage systems improve the performance and increase the range of electric vehicles thanks to an efficient or an optimised performance and provide greater comfort for users. These high-voltage electrification products are intended for vehicles in all sectors of the market, as this type of propulsion enables versatile use of a vehicle, in both urban and highway environments, and complements the 48 Volts systems.

Like the 48 Volts electric motors, these Valeo Siemens eAutomotive full electric motors can be installed between the thermal engine and the gearbox, inside the gearbox or on the rear axle.

The range of high-voltage electric motors starts with a full system (motor + inverter + reducer) providing 40 kW up to the range of a full 300 kW for the most powerful motor, catering for requirements across the entire existing electric vehicle market, from light cars to premium sedans and even the largest SUVs.

In 2022, more than 90 car models will be equipped with the systems developed by Valeo Siemens eAutomotive including a German Premium car maker.
