    TEMA (=Traktions-Energie Messung und Abrechnung)  

Project type:
Implementation into fleet




Project aims:
Energy meters on trains

Application area:
3500 vehicle(s)


In 2000 DB Energie tested the installation of energy meters in several trains as well as data transmission and evaluation in the TEMA project. The meters measure both energy intake and recuperation energy. At DB AG, energy metering is seen as an essential prerequisite for determining the influencing factors for energy consumption and monitoring the success of energy saving measures.
Within the project different types of measuring devices tailored to individual vehicle series were installed and tested. The devices have a minimum accuracy of 1%. The system calculates and records 5 or 15 min consumption profiles. Remote reading via GSM is implemented.Energy meters have now been incorporated into the specifications of new stock. A roll-out into the DB fleet is currently realised. DB AG has introduced exact energy billing based on energy metering since 2003.
