Ford and Samsung have announced a dual-battery system which could increase the fuel efficiency of high volume non-hybrid vehicles.

According to the automaker, the system uses a lithium-ion battery and a conventional 12-volt lead-acid battery. This pairing could enable non-hybrid vehicles to be equipped with a regenerative braking system, which works with an engine start/stop system, for added fuel efficiency.

As Ted Miller, Ford's senior manager of Energy Storage Strategy and Research, explains "We are currently expanding our Auto Start-Stop technology across 70 percent of our lineup, and this dual-battery system has the potential to bring even more levels of hybridization to our vehicles for greater energy savings across the board. Although still in research, this type of battery could provide a near-term solution for greater reduction of carbon dioxide.”

The companies are also exploring an ultra-lightweight lithium-ion battery that could eventually replace the 12-volt lead-acid battery altogether. Ford says the battery is approximately 12 pounds (5.4 kg) lighter than a conventional battery and this weight savings could enable vehicles to become more fuel efficient.
