Abstract
An electrified engine accessory drive (EEAD) system is provided that replaces the front engine accessory drive (FEAD) components (e.g., a/c compressor, air brake compressor; power steering pump, etc.) on vehicles, such as heavy duty trucks. Using such an EEAD system aims to reduce parasitic losses induced on a conventional engine by the front engine accessory drive (FEAD) while providing additional benefits, such as engine off vehicle and/or system operation. The EEAD systems may also be used in lieu of rear-end accessory drives and other accessory drives powering multiple accessories from a common driveshaft.
