Bombardier Transportation has successfully completed a
25.8-mi catenary-free test run using a Bombardier-built tram, powered entirely
by its PRIMOVE battery in combination with Bombardier MITRAC. The test run was conducted
in the German city of Mannheim on the Rhein- Neckar-Verkehr GmbH network.
 In addition to the application in Germany, the PRIMOVE
battery and MITRAC propulsion equipment combination has been in successful
revenue service on the Hexi line in Nanjing, China (shown in the figure)—the
site of the Spring 2016 IEEE Vehicular Technology Conference—since August 2014.
Six trams, built by CRRC Puzhen under Bombardier license, operate without
overhead cables on 90% of the lines. The batteries are charged seamlessly
during passenger service via the pantograph, statically at tram stops, and
dynamically during acceleration.
The system combines high power capacity and exceptional
battery life with high reliability and has been designed to maximize
performance using the latest developments in nickel–manganese–cobalt lithiumion
cells. The advanced PRIMOVE thermal conditioning unit maintains the battery’s
ideal temperature and enables rapid charging and full braking energy recovery
while extending battery lifetime to up to ten years.
