Johnson Controls is adding a lithium titanate battery to its line of automotive battery offerings. The new 12-volt technology, the product of a collaboration with Toshiba, is designed to power Advanced Start-Stop vehicles.
â€œJohnson 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,â€ said VP Lisa Bahash.
According to Johnson, the lithium titanate chemistry is effective at quickly recharging, works well in a wide range of temperatures and can be easily integrated into a vehicleâ€™s 12-volt electrical system.
What Johnson calls an Advanced Start-Stop system has two batteries: a 12-volt Absorbent Glass Mat or Enhanced Flooded Battery, which starts the engine and powers accessories; and a 12-volt lithium titanate battery, which stores regenerative braking energy.
â€œWith an Advanced Start-Stop system, drivers could save up to 8 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,â€ said Bahash. â€œThe technology allows for greater fuel savings without major changes to the existing powertrain and electrical systems.â€
The new 12-volt battery system will be produced starting in 2018
