Ford and Samsung are working together on a new ultra-lightweight lithium ion based battery system which would greatly enhance the capabilities of hybrid vehicles for a greener tomorrow. This could very well be the end of conventional lead acid batteries. Ford Motor Company and Samsung SDI, an associated part of the Samsung Group, is developing a dual-battery system that combines lithium-ion with lead acid batteries. This system will enable regenerative braking pumping more juice back in the batteries, thus, greater fuel savings.

“We are currently expanding our Auto Start-Stop technology across 70 percent of our line up, 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,” stated Ted Miller, Senior Manager, Energy Storage Strategy and Research, Ford Motor Company. He added, “Although still in research, this type of battery could provide a near-term solution for greater reduction of carbon dioxide.” The 10 year research has resulted in a dual-battery system for enabling regenerative braking for non-hybrid vehicles.

Ford’s current electrified lines uses lithium-ion batteries which are 25 percent to 30 percent smaller than previous hybrid batteries made of nickel-metal-hydride, and offer about 3 times the power per cell. This new ultra-lightweight battery concept would offer a weight reduction advantage of up to 40 percent. Combining the battery with other weight reduction solutions, such as the Ford Lightweight Concept vehicle, could lead to additional savings in size and weight of the overall vehicle, as well as increased efficiencies and performance.

Mike O’Sullivan, vice president, Automotive Battery Systems for Samsung SDI North America said, “Lithium-ion batteries are typically used in consumer electronics because they are lighter and more energy-dense than other types of batteries, which also make them ideal for the vehicle. Battery technology is advancing rapidly and lithium-ion could one day completely replace traditional 12-volt lead-acid batteries, providing better fuel efficiency for drivers.”

Current Ford Hybrid vehicles use regenerative braking to capture up to 95 percent of the energy generated due to vehicle braking for reuse. The system works with the Auto Start-Stop system, turning off the engine while stationary and powering the vehicle accessories and systems until the driver releases the brake pedal and the engine restarts. Ford has been spending extensively in battery research and development for nearly 100 years now. The further development of battery technology will leverage innovations in consumer electronics. It will result in reduction in size and weight of automotive batteries, also increasing their efficiencies and capability on hybrid and electric vehicles.
