Johnson Controls Announces New Battery System for Start-Stop Vehicles

10343_johnson Johnson Controls Announces New Battery System for Start-Stop Vehicles In collaboration with Toshiba, Johnson Controls has developed a 12-volt lithium titanate battery system for advanced start-stop vehicles.

‘Johnson Controls is pursuing opportunities to develop evolutionary low-voltage energy storage systems that will help our customers meet increasing fuel regulations at a lower cost than a hybrid or electric vehicle,’ says Lisa Bahash, group vice president and general manager of original equipment at Johnson Controls Power Solutions.

The company says lithium titanate chemistry is effective at quickly recharging, works well in a wide range of temperatures and can be easily integrated into a vehicle's 12-volt electrical system. Toshiba is supplying its SCiB cell technology for the new battery system.

Johnson Controls explains that an advanced start-stop system automatically shuts off the engine when the vehicle is idle and restarts it when the driver's foot leaves the brake pedal. The company says the 12-volt lithium titanate battery will primarily accept and store regenerative braking energy during vehicle deceleration, enabling greater power and load management capabilities.

‘With an advanced start-stop system, drivers could save up to eight percent every time they fill up their gas tank, as the batteries enable the engine to shut off more frequently and for longer periods of time,’ adds Bahash.

The new 12-volt battery systems will be produced starting in 2018.
