  • Evaluating and designing the Electric Power Steering (EPS)
  • Multi-channel simultaneous measurement
  • Real-time calculation

Between 16 to 18% of the total charge of an electric car is consumed as electric drive system losses. Electric and hybrid car manufacturers therefore need to accurately evaluate motor and inverter control in order to achieve higher precision and greater efficiency. Additionally, the accurate analysis of inverter waveforms without interference from switching noise is a key part of evaluating the motor drive circuit.


From R&D to manufacturing and compliance testing, measurement of powertrain efficiency, harmonic content, battery charge/discharge process and ECU communication buses not only require progressively greater accuracies but also consistency in measurement over the specified ranges and conditions.

Range anxiety – the worry that that the battery will run out before a destination or charging point is reached – is among the major barriers for mainstream adoption of electric vehicles. As charging infrastructures still need to be improved, battery efficiency in charging and regenerative braking systems are important.




Using the OR trigger and Dual Capture, it is easy to trap and record failure conditions on electrical harnessses (wiring interconnects) over a long duration test.


With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been shift to high efficiency brushless direct current (BLDC) motors that offer better speed vs torque characteristics, dynamic response and lifespan.

The DL850 Scopecorder can take engineers to a new level of efficiency in the development of everything from green devices to complex advanced systems.


Government agencies that define the standardization of energy efficiency metrics continue to be a driving force behind the development of the next generation electric vehicle powertrains. These metrics require manufacturers to have high confidence in their measurements and motivate the optimization of efficiency.


The request for lower uncertainties in power measurements are increasing,especially in the transformer industries. Their role is to ensure that the electricity is distributed in an efficient and reliable way.

Automotive Manufacturing – Measuring for efficiency

Two key criteria for successful development and mainstream adoption of (hybrid) electric vehicles are - reliability and driving range. The lower the loss in electric systems, the longer their lifetime and the more efficient the drivetrain, the longer the driving range. But as powertrains, charging systems, infotainment and safety systems grow more sophisticated in the ear of the connected car, hybrid and electric vehicle development requires mechatronic analyses of unprecedented certainty and flexibility.

More than a test tool 

Typically, a portable scope or test tool is used by an engineer to diagnose faults on a production line in real-time, or to carry out tests in a workshop. But how can faults be detected and diagnosed when they are intermittent and the engineer needs to be somewhere else? On the other hand, a portable data logger can capture lots of data, including the faults over a period of time, but requires the data to be searched and analysed later to make sense of it.


The WTViewerE is a powerful software that supports remote analysis and control of multichannel measurements from the WT series of Yokogawa power analyzers. In addition to real-time control of remote measurements in multiple formats and customizable layouts, the latest version of the software allows any 4 Yokogawa power analyzers regardless of configuration to be synchronized for multi-unit measurements.  This allows for sophisticated computations for larger applications that may need more than one power analyzer.

    This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.

    In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.

    To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.
