Abstract

A hybrid-electric powered vehicle includes a chassis defining a battery module compartment and a battery module insertable into the battery module compartment. The hybrid-electric powered vehicle includes provisions for recharging a battery module compartment of the hybrid-electric powered vehicle when the electric drive system is operated. The battery module may further be charged by external sources while the battery module is disposed within the chassis, removed from the chassis, and by internal sources when the hybrid-electric powered vehicle is decelerating. In a second embodiment, the hybrid-electric powered vehicle further includes an on-board battery compartment, and a control system that regulates the distribution of power from the electrical power sources to the electric motor. The control system may utilize either the battery module or the on-board battery compartment, or the control system may place the two electrical power sources in series or in parallel, as required to meet electrical power demands.
