Automobile brake technology hasn’t been this interesting since it was found that asbestos brakes caused cancer. Ford has been working with Samsung to develop technology that harnesses the energy produced by friction from vehicles’ brakes. In an article on IEEE Spectrum, Katherine Tweed writes:
Ford and Samsung SDI have partnered to bring hybrid drive technology to Ford’s line up of non-hybrid vehicles to increase fuel economy. The technology, a decade in the making, pairs a traditional lead-acid battery with a lithium-ion battery to allow for regenerative braking.
In hybrid vehicles, regenerative braking allows the battery to capture up to 95 percent of the energy that would normally be lost when a driver steps on the brakes. The technology is integrated into Ford’s Auto Start-Stop, which turns the engine off when the car is stopped to save more energy. Ford said it is currently implementing Start-Stop technology across 70 percent of its lineup.
“This dual-battery system has the potential to bring even more levels of hybridization to our vehicles for greater energy savings across the board,” Ted Miller, senior manager of Energy Storage Strategy and Research at Ford, said in a statement. “Although still in research, this type of battery could provide a near-term solution for greater reduction of carbon dioxide.”
After asbestos was no longer allowed in brakes and rotor disk brakes were widely adopted, there have been few innovations in braking technology. Drilling holes and slots into the brakes has been the extent of any recent developments. If energy-generating brakes were to be adopted across the auto industry, the energy saved would likely offset a significant amount of carbon dioxide emissions.
