start-stop technology fact sheet

Increasingly popular Start-Stop technology makes gas engines more efficient.

Start-Stop technology can be applied easily to standard gas-powered engines.

 

  • Shuts off engine during idle.
  • Restarts engine when the driver’s foot leaves the brake pedal or presses clutch.
  • Easier to implement and less expensive than hybrid and electric technologies.
  • Improves fuel efficiency 3 percent to 8 percent.
  • Reduces greenhouse gas emissions.

Start-Stop vehicles have reached significant production volume in Europe, which meets environmental regulations and saves consumers money. The technology produces even greater fuel savings when combined with other efficiency strategies.

THE BATTERY IS AT THE HEART OF THE START-STOP SYSTEM

JOHNSON CONTROLS IS THE LEADING SUPPLIER OF AGM START-STOP BATTERIES TO POWER START-STOP VEHICLES

Johnson Controls has sold more than 21 million AGM batteries since the technology launched in 2001, topping 5 million annually. We supply all major
European automakers and our AGM batteries also now power Ford’s 2013 Auto Start-Stop and the Chevy Malibu Start-Stop vehicles in the U.S.


Globally, the Start-Stop market for new vehicles could reach 42 million or 40 percent of the new car build by 2018. To support this growth, Johnson Controls invested 100 million Euros to expand its Zwickau, Germany AGM plant making it the largest production facility for AGM batteries in the world. The company also makes AGM batteries in St. Joseph, Missouri and Toledo, Ohio, USA.

AGM TECHNOLOGY IS IDEAL FOR START-STOP BATTERIES

Absorbent glass mat (AGM) technology is the key to today’s most advanced lead acid batteries.
1. Glass fleece separator, like a layer of thick wrap, holds the battery’s acid around the positive grid.
2. Tight-fitting components reduce vibration and
exert uniform, high pressure on the block of plates.
3. Spill-proof battery delivers extreme cycle life and high energy throughput.

WHAT CONSUMERS THINK

Consumers want fuel efficiency but don’t want it to compromise vehicle performance, according to research commissioned by Johnson Controls.


Other findings:
In Europe, the leading global market for Start-Stop vehicles, satisfaction is high.

  • 91 percent of Start-Stop vehicle owners will likely purchase such a vehicle again.
  • 78 percent purchased a Start-Stop vehicle for fuel savings. In the U.S., consumers are looking for fuel-saving technologies.
  • 97 percent say they’re ready for Start-Stop technology.
  • 51 percent would choose a Start-Stop vehicle for its fuel cost savings.
  • More than 30 percent would pay over $500 for a Start-Stop functionality.
