Our customers report significant savings after equipping our smart mobile electric power technology

Using a mobile energy management system can be a strategic way to trim budget or expand the current fleet. One of our current EMS customers has reported enough savings from fuel and maintenance costs to forecast an additional vehicle to their fleet.

EMS vehicles can be retrofit and new vehicles can be ordered equipped with Stealth Power mobile energy management idle reduction technology. Stealth Power systems are custom made and wired into the vehicles existing shore power supplying power to the vehicles inverter.

Austin-Travis County retrofit their EMS fleet with Stealth Power idle reduction technology making them one of the greenest fleets on the streets. Their results:

  • Austin EMS estimates their idle reduction system uses an average of 13.5 hours of electrical distribution per day. In a 30-day month, idle reduction technology provides approximately 405 hours of power, per vehicle.
  • The Austin EMS saves roughly 18.9 gallons of gasoline per day. Typically, a Ford Chassis vehicle without idle reduction technology burns about 1.5 gallons of gas while idle, at a cost of $4.00 per gallon. Austin EMS saves around $75.60 per day in fuel costs for one vehicle.
  • Each month Austin EMS eliminates an estimated 441 idling “ghost miles”(Miles / Wear and Tear reduced on Engine through Idle Reduction) on the engine per day for each vehicle.
  • Monthly, each vehicle eliminates an estimated 4,400 pounds of carbon dioxide.

Savings for each vehicle when monthly usage remains the same:

Stryker

idle reduction military vehiclesWithout mobile power idle reduction technology, a Stryker vehicle idles for up to 5.25 hours in order to maintain 3.75 hours of battery powered operational time, compared to the observed 1 hour of idling to maintain 8 hours of battery powered operational time (silent watch) when equipped with Stealth Power’s mobile electric idle reduction technology.

This equates to a 48% reduction of idling time in nine hours, which aside from the fatigue, noise, and engine wear, equates to 8.79 gallons of fuel (1.675 gal of fuel per hour @ 5KW load) saved for a single Stryker over an nine-hour mission.

HMMWV

vehicle idle reduction militaryWithout mobile power idle reduction technology, a HMMWV could idle for up to 6 hours to maintain 3 hours of battery powered operations compared to one hour of idling to maintain 8 hours of battery powered operational time.

This equates to a 56% reduction of idling time in nine hours equating to 8.8 gallons of fuel for a single HMMWV (1.468gal of fuel per hour @ 5KW load).

Fleets gas / money savings

“We estimated that fuel consumption from idling/recharging alone was reduced by 67 percent on average between all the wheeled vehicles equipped with mobile power idle reduction technology during the experiment compared to those without. Fuel thus conserved will extend range and/or mission length while minimizing or eliminating fuel resupply missions while on patrol.”

Key Results (Military testing)

  • In-rush current of the air conditioner was around 30A (varied by several amps).
  • MEMS was able to start up and run the air conditioner at the test conditions, regardless of whether the TQG was on.
  • 3kW TQG by itself was not able to start up the air conditioner (verified at “room temperature”).
  • The MEMS battery ran the air conditioner 45 minutes from full charge before requiring recharge (32% state of charge), providing about 1.5 to 1.6 kW-hr.
  • With the TQG providing power to the air conditioner, it had sufficient power to recharge the MEMS battery from 32% to 64% state of charge (SOC) over about 55 minutes.
  • With the TQG providing power without running the air conditioner, the MEMS battery was brought from 64% to 100% in about 25-30 minutes.
