Revolve NTNU and 4Test Instruments Partnership Creates Valuable Insights Text by 4Test Instuments Photos by Eskil A. Mogstad (Revolve NTNU)
The technology revolution of electrification of transportation and autonomous self-driving are amongst the most significant impacts to mankind, and it is all happening right now.
For EV testing, there are a lot of considerations and areas to get insight: 1) Testing battery capacity and performance at cell level and pack level. 2) Charging test. For commercial applications a CDS (Charge Discovery System) tester is also es4Test Instruments has transformed its business sential to ensure chargers can interoperate with starting in 2019 to focus on the primary technologmultiple brand EV. ical advancement areas in Norway and the world. 3) Power Semiconductor test, such as double Providing measurement solutions that give scienpulse testers and IV characterization. tists, engineers, and technicians the all-important 4) Inverter testing for efficiency and thermal dymeasurement Insight into how their electronic denamics signs operate during research, development, certification, and manufacturing.

The Revolve team wants to win and learn and 4Test Instruments has the leading measurement solutions that can provide the Revolve engineers the information and insight to characterize, troubleshoot and optimize vehicle powertrain and electronics. Specific examples are battery simulation and tests with a regenerative bidirectional Power supply/ eLoad from ITECH, market leading Keysight Oscilloscopes for measuring inverter/motor drives and troubleshooting with serial communications protocols such as I2C and CAN. Another example is Power Analyzers from Hioki that can measure the efficiency of a power train to get maximum motor torque from minimum energy usage.
