An electric powertrain for a machine includes an electric power source. The powertrain further includes an implement pump for powering a work implement and an implement pump electric motor. An electric traction motor is operably coupled to a traction device. An electronic controller stores a plurality of rimpull torque curves. The electronic controller is configured to determine if the electric power source is in a power limited condition and upon determining that the electric power source is in a power limited condition act to derate a rimpull torque of the traction device from a first rimpull torque curve of the plurality of rimpull torque curves to a lower second rimpull torque curve of the plurality of rimpull torque curves, wherein the selection of the second rimpull torque curve is based on a power usage by the implement pump electric motor.

A controller may determine a battery consumption configuration of the machine based on information regarding the machine, and obtain fuel burn data indicating an amount of fuel burned by the machine. The controller may determine a simulated battery consumption of the machine based on the battery consumption configuration and the fuel burn data. The controller may determine a simulated battery charge level based on the simulated battery consumption. The controller may determine whether the simulated battery charge level satisfies a charge level threshold. The controller may derate an engine of the machine based on determining that the simulated battery charge level does not satisfy the charge level threshold.

A hydraulic system for a machine includes an implement pump, a valve, and an implement valve subsystem. The implement pump includes a load sensing control, and the valve controls the flow of hydraulic fluid to the implement pump. The implement valve subsystem includes one or more implement control subsystems to control movement of an implement. The valve is an electrohydraulic proportional relief valve and includes a solenoid configured to adjust the pressure of hydraulic fluid delivered to the implement pump proportionally to a current delivered through the solenoid.
