Transportation| Rail & Tram | KERS for DMU Trains
Challenge: Improving Diesel Train Efficiency
Background
- Still no energy storage systems in many DEMU trains nowadays
- Drastic regulation changes target resulting noise and CO2 emissions
Key Challenges
- Catenary line is not available in all regions
- Service cost reduction (CAPEX and OPEX)
- Emission reduction
- Constant energy supply from diesel engine
- Sized diesel engine to cater for power peaks
Known Consequences
- Penalties related to high CO2 emissions
- High running and maintenance costs
- Heavy wear on brakes and transmission components
- Negative influence on railway company’s image

Transportation| Rail & Tram | DEMU Cranking Trains
Challenge: Improving Diesel-Electric Train Efficiency
Background
- Diesel engine fails to start in cold climate conditions
- Many batteries must be used to reach the power level to start the engine
- Lead-acid batteries suffer from sulfation and are not reliable
- Frequent checks and replacements to ensure the batteries won’t fail
Key Challenges
- Reliable diesel engine start under all weather conditions
- 100% reliability of the starter function
- Frequent fails due to the use of lead-acid batteries
