Electrified Vehicle Technology - Understanding the Advanced Powertrain Portfolio

Electric Vehicle

Start-Stop Vehicles 
Improve fuel efficiency and emissions
• Minimum change to vehicle systems
• Allows engine to be shut off instead of idling while vehicle is stopped
• 5-10 percent fuel economy improvement and emissions reduction
• All OEs launching platforms in Europe with transition to Asia and US markets 


Johnson Controls is the world leader in advanced lead acid batteries for Start-Stop applications. Advanced lead-acid battery required to start engine more frequently.

What is a Hybrid Electric Vehicle?
Hybrid electric vehicles (HEV) use two different sources of traction power in order to maximize the overall vehicle efficiency.

The most common combination in the market today is a gasoline engine paired with a high voltage battery.

Most HEVs today use Nickel-Metal Hydride batteries.

Battery and engine are primary energy sources for vehicle. Significant reduction of both fuel consumption and emissions
• Two primary types of battery systems
     • Mild: 120V systems provide stop/start and powertrain boost
     • Full: 300V systems supplement with limited electric drive
• Engine downsizing due to lower launch torque requirements

Battery becomes part of powertrain.

Plug-In Hybrid Electric Vehicles
High energy applications for extended electric driving
• Requires advanced lithium-ion battery with more energy and power
• Battery can be charged through standard outlet
• No consensus on optimal all-electric range or battery size 

Battery and small displacement engine are energy sources for vehicle.
