High-voltage
testing

The internal high voltage testing facility allows to test and qualify a wide spectrum of e-traction components, such as motors, power inverters, cells and battery packs, up to 250 kW, 1kV. The testing facility includes a full set of Device Under Test (DUT) conditioning system, as well as high precision laboratory sensors for current, voltage, thermography, flow rate, along with others.
