Renault Trucks Releases Test Summary of Midlum Electrique Semi Truck
In 2012, Renault Trucks released for testing its experimental electric truck Midlum EV developed with IFP Energie and PVI. The truck was tested in the Lyon area in France delivering fresh products to three Carrefour City stores in city for the first six months and then delivering frozen products to six Carrefour Market shops in the Lyon area.
The 18-month long test, financed by the ADEME, ended with 2013 and now we can see the results. Midlum EV covered 16,000 km (about 10,000 miles) and delivered 600 tons of goods.
Christophe Vacquier, Renault Trucks’ product manager, said that the Midlum EV recorded a drop of 86% in CO2 emissions produced from the well to the wheel compared with its equivalent equipped with an internal combustion engine:
“If this figure is applied to the tonne carried, it represents only 2.3 kg of CO2 emitted per tonne! That’s seven times less than an equivalent Diesel vehicle! When used under actual operating conditions, this vehicle demonstrated it consumed only 0.95 kWh per kilometre travelled. This is very little and all the more remarkable since that figure not only includes the energy needed for the vehicle’s propulsion, but also the power used for operating auxiliary equipment such as the cooling system for the refrigerated body or cab heating.”
One other aspect of the truck is regenerative braking, which recovers 25% of energy.
“During deceler ation phases, the propulsion motor becomes an electrical generator which recharges the batteries. 25% of the energy used by the vehicle comes from this generator. This is a very high figure and rather unusual for an electric vehicle. Here again it is able to make energy savings and it proves the driver had been able to drive it in the most appropriate manner.”
Renault Trucks says that the prototype has just minor technical problems with settings or bad electrical contacts.
Nadège Doubinsky, vehicle technical director for STEF (truck operator), was positive about the EV truck, but sees range as too low:
“STEF pays great attention to the most efficient and environmentally friendly technologies. This quiet running vehicle gave us access to a night time delivery slot (from 5 AM to 7 AM) allowing us to respect the peace and quiet of those living in the vicinity. It projects a very positive image to clients and local inhabitants. The only point that needs improving is the vehicle’s operating range. 100 km is not enough for the length of rounds we do in the town centre.”
The driver of electric vehicles seem to always be happy and this time was no different:
“This vehicle is very easy to drive, just like any other vehicle. It didn’t take me any longer to do my rounds. I appreciated its automatic gearbox and its silence. I think it’s the ideal vehicle for making deliveries in town!”
The truck was tested in all weather conditions and in temperatures ranging from -8° to +32°C.
