PDi has developed a method called ReGen-X that allows electric vehicles to recharge their batteries through regenerative braking starting at speeds as low as 10 km/hr during acceleration, coasting, and regular driving. Testing of the technology in HERO Electric scooters showed a continuous recharge rate of 52%, effectively doubling the scooter's range. PDi has partnered with Liberty Electric Cars and HERO Electric to integrate ReGen-X into HERO scooter hub motors. The technology is being demonstrated for automakers like Jaguar, BMW, and others and has generated interest for various applications including electric vehicles, generators, motors, and more.
