Siemens Industry Sector Drive Technologies Division Division Drive Technologies | April 16, 2013 Low-emissions mobility: Siemens supplies drive system for diesel-hybrid buses in France Siemens Drive Technologies Division is supplying a hybrid propulsion system as its contribution to the innovative Mettis transport project to ease traffic congestion in the center of Metz, a city in eastern France. Van Hool, independent manufacturer of buses, coaches and industrial vehicles, is equipping 27 buses with drive motors, generators, power electronics and control software supplied by Siemens. A diesel generator set powers the electric motors in the low-emission, fuel-efficient diesel hybrid vehicles, and a battery system stores surplus energy. A permanently excited drive motor also ensures reliable, low-maintenance operation. The gearless motor installation reduces noise and vibration levels, which in turn improves overall passenger comfort. The double-articulated buses are 24 meters long and 3.3 meters high. They will travel through the city in dedicated lanes separate from other traffic. Their fuel consumption is similar to that of conventional, 12-meter diesel buses, but they can carry almost twice as many passengers. At the same time, the diesel-hybrid drive also reduces environmentally harmful exhaust emissions – and should cut fuel consumption and CO2 emissions significantly down to the lowest emissions-level in this market-segment Download Innovation in dedicated lanes: the diesel-hybrid buses are scheduled to enter service at the end of 2013.

Braking energy is recuperated by the drive motor and fed into the battery system. The battery system used is specially developed for this application and is ideally suited to the starting and braking cycles of public transport buses – it can rapidly store large quantities of energy and deliver it again just as quickly. Siemens is supplying the vehicles with reliable, low-maintenance, permanently excited motors. The drive machines can be installed directly on the axles, and do not require an intermediate transmission unit. This reduces noise and vibration, thus improving overall passenger comfort. Construction work on the Mettis Project began in 2010. This alternative means of transport is scheduled to start running on two routes with a total length of 23 kilometers by the end of 2013. Metz City Council expects it to initially carry 25,000 passengers per day. Later on, up to 36,000 passengers are anticipated to use the new transport system as an attractive alternative to conventional urban buses, trams and private cars.

(Copyright: Van Hool) Background Information The growing need for mobility is leading to a significant increase in city traffic, making the use of private cars more and more uneconomical. This has resulted in a growing demand in our major cities for innovative alternatives in the field of public transportation. Electric drive systems can make buses and other commercial vehicles in our cities both environmentally-friendly and low in energy consumption. With its ELFA modular hybrid drive system, Siemens has a solution capable of meeting every possible requirement.
