A computerized system for use in connection with a hybrid energy off highway vehicle system of a off highway vehicle. The hybrid energy off highway vehicle system includes an off highway vehicle, a primary power source, and an off highway vehicle traction motor propelling the off highway vehicle in response to the primary electric power, and an energy capture system for storing and/or transferring electrical power. An energy management processor carried on the off highway vehicle controls transmission of electrical power among the primary electric power generator, the vehicle propulsion system, an electrical energy capture system, and each of the plurality of dynamic braking resistance grid circuits during motoring, operating and braking the travel of the off highway vehicle.
