Architecting Efficiency: Battery, Hybrid, and Electrohydraulic Systems

About this episode

The episode discusses the integration of electrified hydraulics in mechatronic solutions and the challenges associated with electrification.

Eric Lanke hosts Philippe Reynolds, director of Poclain Hydraulics' Electromobility program, in an NFPA Fluid Power Forum episode tied to the NFPA whitepaper "Energy Efficiency Gains from Electrified Hydraulics." Reynolds explains Poclain's shift from component supplier to system partner integrating hydraulics, electric drives, power electronics, sensors, and software into mechatronic solutions, including electric drive units like the eWheel for compact equipment. He outlines electrification challenges—system complexity, energy and thermal management, architecture selection (battery electric, hybrid electrohydraulic with energy recovery, and series hybrid for heavier machines), and the need for decentralized power-on-demand designs to boost efficiency. The discussion highlights duty-cycle-based sizing, liquid cooling to control operating conditions, lessons adapted from automotive and other industries, and the growing importance of functional safety, compliance, plug-and-play integration, and supplier–OEM partnerships.
