Abstract
An electrical energy system for a work machine includes a rechargeable electrical energy source to provide electrical energy to power the work machine, multiple energy management devices, and a system controller. The multiple energy management devices each include at least one electrical component. The energy management devices are modular, and the electrical component or components of each energy management device are independently activated for that energy management device. The system controller is configured to activate the at least one electrical component of all the energy management devices in response to a predetermined event, monitor all the energy management devices for faults, and deactivate a portion of the activated electrical components of the energy management devices according to demand on the electric energy system.
