6/29/26 Duty Cycles, Machine Learning, and Energy Efficiency: Optimizing Electrified Hydraulics Host Eric Lanke interviews Barun Acharya, system engineering manager for electrification at Parker Hannifin, about energy efficiency gains from electrified hydraulics and insights tied to NFPA’s white paper and a CONEXPO technology conference. Acharya describes how emissions rules, noise limits, and ESG mandates are driving electrification, and outlines key challenges including unclear duty cycles (addressed via energy mapping), power-density mismatch between hydraulic and electric actuators, complex system integration (CAN, software, EMC, operator feel), and revealed hydraulic noise once diesel is removed. Guests Dr. Jake Swanson (Minnesota State University, Mankato), Dr. Brian Steward (Iowa State University), and longtime technical liaison Ernie Parker (recently retired from Hennepin Technical College) discuss how the competition’s resources and industry mentoring support student learning, how the challenge has scaled to multiple sites and improved rules over time, and common hurdles such as design, component sizing, ordering and time management, and limited hands-on shop skills.
