Abstract
Electrification is an increasing trend in developing the next generation of large-scale off-road vehicles. Benefits of electrification are high operating efficiency, low emissions, the possibility of using energy coming from renewable sources, and improved controllability. Despite the growth of these technologies there is no clear direction for how the system should be electrified. This research focuses on defining a standardized methodology to design different electro-hydraulic units that can function as a prime mover for a wide variety of applications. The electro-hydraulic units are designed using a genetic algorithm-based optimization that couples one model dedicated to the hydraulic machine and one model dedicated to the electric machine and determines the optimal parameters of the electro-hydraulic unit given a specific application. After having designed an external gear-type, internal gear-type, and an axial piston-type hydraulic machine, several prototypes are produced, and tested on a reference machine.
