NiMH traction batteries for Nice trams
25 October 2005 12:45
Saft has won a €2 million order from Alstom to supply Ni-MH (nickel-metal hydride) integrated traction battery systems for its CITADIS trams currently under construction for the city of Nice. The new hybrid trams, due to commence service in 2007, on line one of Nice's new tramway system, in the south of France, will be able to switch their source of traction power between overhead catenaries and the on-board batteries for wire-free operation in the downtown area.
Since the tram route will cross Nice's two historic town squares (Place Masséna and Place Garibaldi), the local authorities asked for a low impact solution to keep these areas free of overhead wires. Therefore, Alstom needed an onboard traction battery capable of providing sufficient power for travel over sections of track where catenaries were not available. The system also had to be compact enough for installation on the vehicle roof.
Saft has developed a fully-integrated battery for this new generation of tramways. The Saft Ni-MH battery systems offer excellent power storage in a compact maintenance-free package, and will power the trams for around 500m through each autonomous section. Saft's new generation NHP nickel-metal hydride battery modules offered the ideal solution as they were developed specifically for high power applications.
The Saft battery system is an ideal solution for various hybrid and bimode applications. Each battery system incorporates an active cooling device and battery management control. The whole unit is supplied ready to 'plug and play' in a custom built tray complete with power and communication capabilities and all necessary safety features.
