Cold Weather No Problem for Ford Focus Electric Vehicle Liquid-Heated Battery System
Tuesday, March 8, 2011 at 6:53PM Source: Ford Motor Company Ford’s use of an advanced active liquid-cooling and heating system to regulate the temperature of its lithium-ion battery packs in Focus Electric will provide customers in cold and snowy climates an advantage. The liquid-heated battery operates under a range of ambient temperatures, providing additional power, longer battery range and a preconditioned battery after charging. “Batteries are similar to people as they both achieve maximum performance working under moderate, unchanged temperatures,” said Sherif Marakby, Ford director of Electrification Programs and Engineering. “Using a liquid-heated battery system allows Ford to keep the Focus Electric’s battery at a moderate temperature and improve performance whether you are charging or driving in a cold climate.”
