PROBLEM TO BE SOLVED: To provide methods for determining when and how to discharge electrical energy that has been stored during regenerative braking of an off highway vehicle (OHV).SOLUTION: An energy management system 119 comprises an energy management module 116 that electrically connects an energy storage system 114 of an OHV 100 with a traction link 106 of the OHV, the traction link being electrically connected to a plurality of traction motors 110#1 to 110#n. The energy management module is configured to deliver electrical power from the energy storage system to the traction link in a haul route, according to a discharge rule that is selected by a comparison of predicted performance of a plurality of discharge rules to a baseline performance of the haul route. In the haul route electrical power is not delivered from the energy storage system to the traction link, in order to obtain fuel savings, speed excess, or a combination of fuel savings and speed excess relative to the baseline performance. |
