Electric Vehicle Powertrain Testing Solutions
Gain valuable insight into the performance of electric powertrain systems without second-guessing the quality of your power measurements. From the battery to the motor output and everything in between, Yokogawa's wide range of instruments enable engineers to confidently and comprehensively analyze electromechanical challenges of EV powertrain systems.
Understanding and Quantifying Power Loss in EV Powertrains
To develop and optimize efficient and sustainable transportation solutions, it’s critical that engineers and researchers accurately identify, quantify, and understand the losses from each component (e.g., battery, inverter, motor) as power flows through the complex network of an electric vehicle powertrain system.
Effective measurement and analysis of the various measurement test points along an EV powertrain requires specialized equipment such as power analyzers to ensure the highest quality data with the fewest potential trade-offs. Selecting the instrument best suited to a specific application ultimately comes down to the application's required level of accuracy, number of channels needed, and types of signals being acquired.
For automated inverter and motor testing, the WT1500 Precision Power Analyzer measures up to 2,000 V DC directly with ±0.038% power accuracy, up to four wattmeters, and a compact 2U design built for test racks.
Revolutionizing EV Powertrain Testing with Integrated Measurement Tools
Yokogawa’s suite of high-precision instruments, including the ScopeCorder, Power Analyzer, Oscilloscope, and Data Acquisition devices, work together seamlessly to deliver world-class electric vehicle powertrain testing results. Leveraging our advanced integrated software platform, our tools collectively ensure precise measurement, analysis, and optimization of every component within the EV powertrain system.
- ScopeCorder: Captures waveforms, flow, vibration, resolver signals, and CAN bus data, providing a detailed overview of dynamic and static signals in real time.
- Power Analyzer: Measures AC/DC voltage and current, power, encoder signals, torque, and efficiency to evaluate energy transfer and loss within the powertrain.
- Oscilloscope: Monitors CAN bus, SPI bus, I2C bus, isolated voltage, IGBT signals, and flow, essential for detailed analysis of electronic control units and other complex circuits.
- Data Acquisition Devices: Collect temperature, DC voltage, frequency, and input/output data to ensure comprehensive environmental and electrical condition monitoring.

Use built-in calculations to analyze motor rotor position of Brushless DC motors (BLDC) and Permanent Magnet Synchronous Machines (PMSM) and find the relative angle between the rotor and position sensors such as encoders or resolvers
Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.
How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible.
