NOVELTY - A hybrid vehicle (1) has an equipment circuit (11), including an equipment battery set (21), providing electricity to a body builder electric equipment (20). An equipment battery set sensing device (22) provides at least a state of charge of the equipment battery set. An equipment converter (23) interconnecting the equipment circuit to a driving circuit (7) transfers electricity from the driving to equipment circuits. A body builder interface and controller (25) manages the converter so as to provide electricity to the equipment circuit according to the state of the drive system (D).    USE - Hybrid vehicle. Uses include but are not limited to e.g. personal cars, commercial vehicles, trucks, refuse vehicles, emergency vehicles.    ADVANTAGE - Body builder equipment e.g. powered tailgates, tippable platforms, cranes, hoists, concrete mixers, garbage compactors, can be powered in controlled manner so as to fine tune use of available energy, reducing fuel consumption of vehicle. State of charge of driving battery set and equipment battery set can be set up, enabling either battery set to be available for accumulating electricity recovered during slowing down phase of vehicle movement. Implementation of electrical converter with off-board plug enables converter to suit to vehicles e.g. refuse vehicle, with short periods of use when compared to parking period. Implementation of body builder interface facilitates work of body builder while installing equipment on vehicle. Using lower cost constant flow hydraulic pump for body builder reduces total cost of body builder equipment system. Each equipment battery is optimized for deep cyclic uses and for total energy capacity or with low or medium internal resistance optimized for efficient low or medium duration high current output, while each driving battery is with low internal resistance optimized for efficient low duration high current output.
