Abstract:

The main objective of this thesis is to electrify the mobile hydraulic application through the Electro-hydraulic actuator implementation (EHA) integrated with two novels-designed electro-hydraulic units (EHU) which consist of fixed displacement pump and variable speed electric motor (PMSM) with higher compactness and it act as the prime mover in high power-level applications such as off-road mobile applications like construction, agriculture machines and mining machines. The valve manifold contains the needed electro-hydraulic parts to manage the cylinder actuation with the help of electro-hydraulic unit (EHU) control. The efficiency of the proposed system is analyzed under steady state and real drive cycle of industrial compact loader. To power those off-road vehicle, high voltage storage devices are required so we perform different evaluations and simulations for the sizing of battery system which power EHA system by enabling energy recuperation during assistive drive cycles and also review the charging technology which made it feasible.
