Test systems are complex and sophisticated with many elements to be tested and coordinated. Most vehicles use 3-phase AC motors driven by inverter technology, so power analyzers need to measure 3-phase AC power with a large amount of harmonic content. Hybrid or electric driveline testing is conducted at several stages during the development of a vehicle, and each has an important role to play.Д®ngineering testing вЂ“ design engineers need precise measurementsДЄccurate measurements are critical so design engineers can extract efficiency from their designs, or they will lose the advantage of using hybrid/electric technology. The testing technology is energy efficient, reducing operations and maintenance costs, and contributing to the vehicleвЂ™s overall environmental performance. The technology is out there to ensure proper testing and realization of the energy efficiency benefits promised by hybrid and electric vehicles. Changing technology and increased complexity require a testing system very different, and more complex, than those used in IC-only systems. The test system needs to communicate with one or more of these units through high-speed in-vehicle networks to properly test components. These vehicles have several module control units (MCUвЂ™s), small onboard computers, controlling the functions of the engine, transmission, and charging system. Hybrid and electric systems use regenerative braking where braking generates power that is returned to and stored in the vehicleвЂ™s battery for later use, requiring AC inverter technology and transmissions. Hybrid and electric drivetrains have several features making testing them different from the standard testing conducted on internal combustion (IC) only systems. ItвЂ™s important to conduct driveline and component testing during design and manufacturing thatвЂ™s adapted to hybrid and EVs to gain the efficiency benefits and green profile of these vehicles. Automotive, military, aircraft, and space systems have seen a surge of interest in hybrid and electric vehicle (EVs).
