Johnson Controls Power Solutions and Toshiba Infrastructure Systems and Solutions have partnered to deliver low-voltage lithium-ion options.

Johnson Controls will collaborate with Toshiba to develop and manufacture lithium-ion batteries at its Holland, Milwaukee plant and pair them with existing lead-acid battery technology as part of dual-battery systems.

Dual-battery vehicles are expected to be the fastest-growing form of electrification and by 2025 will account for around 20% of new vehicles built globally. Adoption rates will be even greater in locations with strict fuel economy standards.

Paired systems require minimal powertrain alterations, so automakers can deploy them across multiple vehicle lines with a lower investment than other electrified powertrains. Consumers also benefit, as paired systems achieve up to 8% greater fuel efficiency than a conventional system.

"Low-voltage dual-battery technology is the next step in the evolution of vehicle systems that helps to strike a balance between consumer demands, increasing regulations and automaker economics," said Johnson Controls Products, Power Solutions, group VP, Brian Cooke.

"Combining Johnson Controls' partnerships and battery system capabilities with Toshiba's lithium-ion cell expertise provides automakers with a competitive product."

The Holland, Milwaukee plant opened in 2010 and was first in the US to produce complete lithium-ion battery cells and systems.

The two companies plan to collaborate on future technology development and exploration of additional applications where Toshiba technology can be integrated.
