Abstract
A refuse vehicle including an electric motor powered by a battery, a hydraulic pump driven by the electric motor, a manifold including a plurality of electrically actuated solenoid valves receiving hydraulic power from the hydraulic pump, a hydraulic actuator powered by the hydraulic pump via the manifold, and one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: determine a load applied to the hydraulic actuator, operate the manifold to provide regenerative flow of hydraulic fluid to the hydraulic actuator when the load is less than a threshold load, and operate the manifold to provide non-regenerative flow of hydraulic fluid to the hydraulic actuator when the load is greater than or equal to the threshold load.
