Abstract

An intelligent work vehicle filtration system includes a hydraulic subsystem, a controller architecture, and an electric drive subsystem containing a battery pack. A hydraulic subsystem includes, in turn, a fine filter device having a first filter efficiency, a coarse filter device having a second filter efficiency less than the first filter efficiency, a hydraulic circuit in which the fine filter device and the coarse filter device are positioned, and a hydraulic pump controllable to circulate hydraulic fluid about the hydraulic circuit. During operation of the intelligent work vehicle filtration system, the controller architecture selectively places the intelligent work vehicle filtration system in an externally-powered filter mode in which hydraulic flow is directed through the fine filter device, while bypassing the coarse filter device, when the electric drive subsystem is electrically coupled to an external power supply utilized to charge the battery pack.
