Johnson Controls to unveil micro hybrid lead-acid/Li-ion battery demonstration module at North American International Auto Show
10 January 2013
Johnson Controls, Inc. will introduce a 48V Micro Hybrid battery demonstration module as part of its full spectrum of advanced energy storage solutions for automobiles at the North American International Auto Show in Detroit.
Leveraging a dual voltage architecture, Johnson Controls’ Micro Hybrid battery system would involve a low voltage lead-acid battery and a 48 volt Lithium-ion battery that enable optimization of energy generation and consumption, thus saving fuel.
In prospective development programs with key automakers, the 48 volt battery could support higher power loads such as electric air-conditioning, active chassis technologies and the capture of direct regenerative power energy braking. The 12 volt battery would continue to provide power to the vehicle starter, interior and exterior lights, and entertainment systems such as radios and DVD players.
Johnson Controls sees opportunities for the development of evolutionary energy storage systems that offer even more fuel efficiency than Start-Stop at less cost than a hybrid or electric vehicle. Even as Start-Stop vehicles become part of the mainstream in Europe and start to take hold in the US, Micro Hybrid technology has the potential to deliver the next level of fuel efficiency along the spectrum of vehicle performance, reaching upwards of 15 to 20% in fuel economy.
We expect this technology to be adopted in Europe first, due to more stringent fuel economy and emissions standards, and then quickly move to US markets in the next few years with mass adoption by 2020.—Alex Molinaroli, president, Johnson Controls Power Solutions
