Idle-Stop Systems

Basics

• They are more commonly reffered to as "Start-Stop" or "Stop-Start" systems, however Idle-Stop Systems is used in papers etc
• Systems for Internal Combustion Engines , typically for Vehicles, where when idle for a certain amount of time (long enough that it isn't a small pause), the engine will turn off automatically
• Then when the "gas pedal" is pressed again, or new power is needed for ongoing electronic/mechanical devices once the "reserve" has been used up, it will automatically turn back on
• The Starter Motor is typically upgraded to make this process faster as well
• In situations such as start-stop traffic, or door to door delivery (mail trucks etc), this can significantly reduce fuel use, and decrease Emissions
• Much of the technology may be of use in backup / Microgrid generator systems as well
• This system usually consists of:
  • An Improved Starter Motor
    • And thus often electonics, such as more battery storage, higher power electronics, etc
  • A Batery Managment System Interlinked with the Car's Electronic Control Unit (Automotive) that can plan when to turn off the engine without being too "annoying"
    • Aso an overide button is included as well for this exact reason
• A Novel Method Utilizes (Often purely mechanical) FES to allow for lower cost/complexity (see the paper below)

Current Industry Leaders

Corvus Energy

• This is centered towards the marine sector
• Thus not a 1-to1 comparison, but their systems allow for this as well as Cold Ironing (Marine Engineering) and storage of energy to act as a Reserve Power system rather than another engine/genset thus reducing operating costs + space
