Electric Aircraft Test Solutions
NH Research (NHR) provides power test equipment for electric aircraft components and systems including battery modules/packs, electric propulsion and power electronic systems. Our customers include commercial, military aircraft and private manufacturers and suppliers across hybrid and fully electric aircraft, e-VTOL, drones, and urban air mobility (UAM) platforms.
A major limitation for electric-powered planes is the weight and capacity of the battery. Electric planes require lighter weight batteries with higher energy density to make electric flight feasible. Higher voltages increase power transfer and reduce vehicle weight. These factors are driving development for higher performing and higher power electric aircraft systems including batteries, electric motors, power distribution units (PDUs), power converters/inverters and chargers.
Next Gen Battery Module/Pack Test Solutions
Electric aircraft requires lighter weight batteries with higher energy density to make electric flight feasible. NHR’s battery module and pack test systems are ideal for rigorous EV life/drive cycle and performance testing. The 9300/9200 Battery Test System provides scalable power, fast transients and multi-layered safety features built-in so you can safely push the boundaries of test.
Electric Propulsion Test Solutions
NHR’s electric propulsion test solutions provide a bi-directional approach with the speed and accuracy to emulate real world conditions. NHR’s 9300/9200 Bi-directional DC Source can be used to emulate a high voltage battery and the DC Bus. The 9300/9200 Bi-directional DC Source accepts back EMF and prevents safety hazards. NHR’s battery/motor emulation capability sinks & sources to maintain voltage regulation. The isolated input and output paths are designed to eliminate single points of failure.
Power Distribution Unit (PDU) Test Solutions
NHR provides safe and accurate solutions for testing power distribution units (PDU) which route multiple high power sources and loads throughout the electric aircraft. NHR’s DC loads are ideal for multi-channel load testing while NHR’s 9300/9200 bi-directional DC source can be used to emulate the PDU power source.
