Patent attributes
An electrical power system for a delivery vehicle. The power system is used in connection with a vehicle having an engine, and a liftgate powered by an electric motor. The power system includes a first battery, a second battery, and an alternator. The electrical power system also includes a super capacitor. The super capacitor has a first capacitor bank and a second capacitor bank, wherein each of the first and second capacitor banks comprises ultra-capacitor cells placed in series. The first and second capacitor banks reside in parallel. In addition, the first and second batteries reside in parallel with the second capacitor bank. Together, the batteries and the second capacitor bank supply power to the liftgate motor. Finally, the first capacitor bank is in electrical communication with the alternator and supplies power, with the alternator, to a relay start for the delivery vehicle to start the engine.
