Abstract
A hybrid power module is provided. The power module is associated with a truck having a lift gate. The power module includes a super capacitor comprising a bank of capacitors, with the super capacitor being in electrical communication with an alternator of the truck. The power module also includes a battery, a switch, a DC/DC boost converter, and electrical wiring. The electrical wiring connects the capacitor bank and first battery to the switch, and further connects the switch to a motor for the lift gate. The super capacitor and the first battery are positioned in parallel, with the super capacitor and the first battery residing proximate the lift gate. The super capacitor contains enough energy to power the electric motor for the lift gate through at least two operating cycles without the battery, protecting the lift gate if the battery goes weak.
