TECH FOCUS: TESTiNg AND DigiTAl TwiN Overcoming EV drivetrain testing challenges SAKOR's Dynolab can be adapted to automate all aspects of electric powertrain testing. current) were never designed to handle the types of precision required by hybrid or electric powertrains. Nor can they test the regenerative (motoring) modes of operation. Hybrid/EV test systems must provide all the functionality of traditional systems, with the added ability to test high-power regenerative electrical drives, high-voltage battery, and 22 May 2024 charging systems and communicate with any number of smart control modules. For many larger hybrid/electric drivetrains, there is a strong trend toward using higher voltage, higher efficiency drive systems. Going from the traditional 12/24-volt DC electric system to one using 240 volts AC will typically require one-eighth or less of the current to deliver the same power. Not only is this more efficient, but it also requires much smaller/ lighter wiring and smaller components to transfer the energy. Many current designs operate at 800 volts or more, making the vehicles even more efficient. UPDATE SAKOR Technologies
