TECH FOCUS: TESTiNg AND DigiTAl TwiN EV motor production test stand installed at a Tier 1 supplier's facility. Overcoming EV drivetrain testing challenges By RANDAl BEATTiE, President at SAKOR Technologies, Inc. This article also appears in Truck and Off-Highway Engineering and was edited for Update. Transportation markets have seen a tremendous surge of interest in hybrid and electric vehicle technology. To gain the promised efficiency benefits and green profile of these vehicles, it is important to conduct driveline and component testing 20 May 2024 during design and manufacturing that is specially adapted to hybrids and EVs. Hybrid and electric drivetrains have several features that make testing them very different from the standard testing conducted on internal combustion (IC) only systems. Hybrid and electric systems use regenerative braking, which typically requires the addition of AC inverter technology and, often, more complex transmissions.
