TM4 Equips the Cleanova II: the Latest Electric Vehicle of S.V.E.

Boucherville, Quebec (ots/PRNewswire) - TM4 has developed and produced the drivetrain system of the Cleanova II, the new hybrid electric vehicle that is presented at the Paris Auto Show by the Société de Véhicules Électriques (S.V.E.), company formed by the Dassault and Heuliez groups. The Cleanova II, based on a Renault Kangoo platform, is displayed at the Heuliez stand.

This multifunction drivetrain system integrates, in one single module, a 35kW electrical motor and a 15kW range extender generator with an integrated differential. Moreover, this system includes in this same module all the associated control and power electronics, the DC-DC converter and the battery charger. TM4's system makes of the Cleanova II a hybrid vehicle that runs primarily in electric mode. The Cleanova II versatile hybrid system allows for many uses. Firstly, it can operate in all-electric mode. Secondly, the generator, that is typically used to recharge the battery as a range extender, can also be coupled to the main electrical motor to boost its performance, depending on road conditions and the driver's requests.

TM4's motors utilise permanent-magnet technology, which helps reduce energy consumption, the size and weight of the motors, therefore increasing the performance and driving range of the Cleanova II. S.V.E. intends to commercialise this vehicle in the second half of 2006. A full electric version of that vehicle, also equipped with a TM4 drivetrain, will be commercialised concurrently.
