As electric vehicle (EV) technologies continue to evolve, improving powertrain efficiency and accurately quantifying power losses have become critical to developing high-performance and sustainable transportation systems. Yokogawa Test & Measurement addresses these challenges with a comprehensive portfolio of test and measurement solutions designed to provide engineers with precise analysis of electrical and mechanical performance throughout the EV powertrain—from the battery and inverter to the electric motor and drivetrain components.
At the core of Yokogawa's EV powertrain solutions is an integrated measurement platform that combines power analyzers, oscilloscopes, ScopeCorders, data acquisition (DAQ) systems, and analysis software to deliver synchronized measurements across multiple test points. The company emphasizes that accurate power measurement is essential for identifying, quantifying, and understanding energy losses within complex EV powertrain systems, enabling engineers to optimize overall system efficiency and performance.
The platform supports a broad range of EV powertrain testing and validation applications, including electric motor power measurements, inverter characterization, battery performance evaluation, high-voltage onboard charger testing, field-oriented control (FOC) analysis, resolver design and testing, rotor position analysis, and synchronized motion and analog signal measurements. By integrating electrical, mechanical, and control signal analysis within a single measurement environment, Yokogawa enables comprehensive validation of powertrain components throughout the development process.
A key focus of the company's technology is high-precision power measurement for efficiency optimization. Yokogawa's solutions help engineers evaluate power flow through the battery, inverter, and motor while analyzing parameters such as voltage, current, power, harmonics, pulse-width modulation (PWM), and energy losses. The company also provides dedicated tools and application guidance for advanced motor control techniques, including Maximum Torque Per Ampere (MTPA) optimization and Field-Oriented Control (FOC) measurements, supporting the development of high-efficiency electric drive systems.
Complementing its hardware portfolio, Yokogawa offers an extensive library of application notes, white papers, case studies, and software resources to assist engineers in developing, validating, and optimizing EV powertrain technologies. Together, these solutions enable accurate and repeatable measurements across the entire electric propulsion system, helping manufacturers improve efficiency, reduce power losses, and accelerate the development of next-generation electric vehicles.
