Skeleton Technologies ultracapacitor rail applications

Engine Cranking
for demu trains

Reliable engine start even in extreme weather conditions

Benefits of our solution

  • No battery-related start failures anymore
  • Safety & reliability even in extreme temperatures (-40°C to +65°C)
  • Ultracapacitors are considerably lighter than batteries

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
  • known consequences
  • Costly downtime due to the failures when starting the DEMU
  • Increased maintenance costs due to preventive battery replacement
