Abstract:
1. A braking regeneration energy shunt system for a turf maintenance vehicle comprising: a power bus; a traction motor coupled to the power bus, the traction motor developing a back electromotive force that can be directed into the power bus as regeneration energy; an energy storage device coupled to the power bus, the energy storage device selectively providing electric current to the power bus and selectively receiving electric current from the power bus; a resistor array having a plurality of resistors, the resistor array selectively dissipating regeneration energy into heat; a control module monitoring at least one of a voltage of the power bus and a state of charge of the energy storage device, the control module selectively directing regeneration energy created by the traction motor into the resistor array for dissipation as heat based on at least one of the voltage of the power bus and the state of charge of the energy storage device; wherein the control module ascertains the number of resistors needed to dissipate the regeneration energy directed to the resistor array and directs the regeneration energy simultaneously to the ascertained number of resistors.
