Business alliance between measurement and calibration solutions vendor ETAS and electrical measuring instrument manufacturer HIOKI

ETAS K.K. (Headquarters: Nishi-ku, Yokohama, President & Representative Director, Takayuki Yokoyama, hereinafter, “ETAS”), which provides measurement and calibration solutions for ECU software and HIOKI E.E. Corporation (Headquarters: Ueda, Nagano, President & CEO, Kazutoshi Hosoya, hereinafter “HIOKI”), which engages in electrical measuring instrument development, production, sales, and services announce a business alliance. The purpose of this alliance is to fuse high-precision electrical measuring technology and measurement and calibration solutions, which are essential to improving the efficiency of electric powertrain development.

Market background

In the automotive industry, there is currently a demand for the massive technology innovation represented by CASE (Connected, Autonomous, Shared, and Electric).
Larger capacity for storage batteries represented by lithium-ion batteries, inverters with increased switching frequencies through the evolution from IGBTs to SiC, and new electrical measuring technologies based on the higher responsiveness of the motor system are needed, particularly in the electrification arena. There is also demand for the efficient development of ECU software for controlling these technologies.

Effect of the business alliance

The solutions provided by ETAS will be fused with high-precision electrical measuring technology provided by HIOKI for everything from advanced development of electric powertrains to actual vehicle experiments.
As one example, in electric powertrain development, motor operating conditions and output are determined by using ECU software to calibrate voltage and current while measuring electrical parameters such as voltage/current values and power loss. Synchronizing ECU software calibration using ETAS’s INCA with electric energy measurement using HIOKI’s Power Analyzer PW6001 will greatly contribute to more efficient electric powertrain development.
Furthermore, HIOKI has realized the SP7001 non-contact CAN/CAN FD sensor to apply electrical measuring technology. Combining this sensor with ETAS’s INCA will make it possible to measure information from vehicle-mounted networks without fabricating harnesses.

Solution features

Add-ons will enable HIOKI power analyzer measurement data to be recorded in INCA. Connecting ETAS’s INCA with HIOKI’s PW6001/PW3390 will enable seamless execution from actual PCU verification to calibration on test benches.

Solution advantages

Recording ECU control values and CAN communication via a single measurement data element can enhance analysis efficiency. Expressing power analyzer measurement data with INCA’s rich GUI will prevent worker analysis errors. Furthermore, since power analyzer settings can be changed from INCA, main unit operations can be reduced.
Additionally, power analyzer measurement data can be input to INCA directly via digital communication without errors, which will improve calibration accuracy. This also contributes to high-precision plant model generation since high-precision data can be obtained when plant models are generated from actual measurement data.
