TM4 has the skills and resources to assist you throughout the product development process of your Electric Traction System and supply you in volume.
In 2003, TM4 custom-designed the first generation of Electric Traction Systems for SVE’s Cleanova. This system is an integrated traction system combining an electric
coupled to an
internal combustion engine
(ICE). This unique traction system uses a clutch system that enables reconfiguration of the drive line from a high torque electric vehicle to a series hybrid. The latest version of the system is a dual system, series parallel hybrid or electric, on command.
Nominal output power: 37 kW
Max output power: 60 kW (30 sec)
Nominal output torque: 300 Nm
Max output torque: 1550 Nm (30 sec)
In its high torque configuration, both the generator and the electric traction motor are coupled to the wheels to provide traction torque.

At higher speed or in low torque situations, the generator can be decoupled from the wheels and coupled to the ICE to provide power to recharge the main traction battery, extending the vehicle range.
The second generation system integrates a unique 4 position magnetic clutch that permits the system to work in a parallel hybrid mode on demand.

The experimentation of 30 pre-series Cleanova II vehicles is currently mandated by the PREDIT, a research, experimentation and innovation program for land transport, funded by the French Government. Vehicles are being tested by La Poste (8), as well as by Électricité de France (EDF), Veolia Eau, Accor, ALD Automotive and two other fleet managements.
