French Post Office to Test French Electric Vehicle


The French post office (La Poste) will test the Cleanova II—a series hybrid light delivery van manufactured by SVE (Société de Voitures Électriques, electric car company), a joint venture between specialist car body supplier Heuliez and the Dassault group.

Assuming the testing with La Poste—and presumably some others—goes well, SVE intends to commercialize the vehicle in the second half of 2006. A full electric version of the Cleanova II, also equipped with a TM4 drivetrain, will be commercialized concurrently. The target is fleet buyers in Europe and North America. Groups in China and India are also reportedly interested.

The Cleanova II—based on the Renault Kangoo—is the second-generation of electric vehicle from SVE, and made its debut at the Geneva Motor Show earlier this year.


An electric drivetrain from TM4, a subsidiary Hydro-Québec, the giant Canadian energy company, powers the Cleanova II. The drivetrain is a multifunction system that integrates a 35 kW electrical motor, a 15 kW range extender generator and a differential in a single module. The drivetrain module also includes all the associated control and power electronics, the DC-DC converters, and the battery charger. (See image at left.)

The vehicle uses a new Lithium-Metal-Polymer battery from Avestor (also a Hydro-Québec subsidiary) for storage.

Avestor claims that the LMP batteries offer advantages such as a much higher energy capacity per unit volume and unit weight, and a very predictable and stable charge/discharge characteristics over varying environmental conditions—all very good qualities for an electric vehicle battery. A chart from Avestor comparing the energy capabilities of different technologies is below.

Electric Vehicle Battery Technology
Technology Specific Energy(Wh/Kg) Energy Density (Wh/l) Specific Power (W/kg) Cycle Life (Cycles)
Prototype Lithium-Metal-Polymer 121 143 241 300
Projected Commercial Lithium-Metal-Polymer 120 160   800
Li-ion 138 210 430 550
NiMH 63 150 200 800
Ni-Cad 50 90 120 800
Lead-Acid 36 86 180 600

The Cleanova II has a range of 180–200 km (112–124 miles) in battery mode. Using the engine as a range extender increases that to 400–450 km (250–280 miles). The engine can also be coupled to the main electrical motor to boost performance.
