The Johnson Controls Advanced Start-Stop system solution has two batteries. First, a 12-volt Absorbent Glass Mat (AGM) or Enhanced Flooded Battery (EFB), which will start the engine and supply power to accessories such as lights, navigation systems and radios. Second, a 12-volt Lithium-ion battery, which uses a proprietary Titanate chemistry, will primarily accept and store regenerative braking energy during vehicle deceleration, enabling greater power and load management capabilities.

In collaboration with Toshiba, the technology used in the 12-volt Lithium-ion battery 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.

In China, passenger vehicles need to achieve a fuel consumption target of 5 liters per 100 km in 2020, versus 6.9 liters per 100 km in 2015—a 27% improvement.

The Advanced Start-Stop battery, which made a global debut at the North American International Auto Show in January, will be produced starting as early as 2018. (Earlier post.)
