EVAOS, Inc (Electric Vehicle Add-on Systems) Information

EVAOS designs, manufactures, and sells add-on systems that upgrade conventional trucks into plug-in hybrid electric vehicles. The company was founded in 2012 by Don Matheson, former Director of Engineering Operations at Tesla Motors, and is headquartered in California's Silicon Valley. Because EVAOS equipped trucks keep their original gas or diesel engine and transmission, they have three different driving modes: all-electric mode for maximum fuel savings, hybrid mode for longer trips or extra towing power, and conventional mode for extended range. EVAOS systems can also power external electrical equipment in locations where the electrical grid is unavailable. The company's solution for Ford F-150, F-250, and F-350 pickup trucks entered production in mid-2014, with similar solutions for other vehicle makes and models to be offered later.
