FEV presents high-voltage electric discharge detection system
With PD-HVX (“Partial Discharge-High Voltage X”), the development service provider FEV has developed a solution for the early detection and prevention of partial discharge in high-voltage vehicle drives. FEV states that partial discharge can cause damage to the insulation in modern electric drives, which in the worst-case scenario can result in a total loss of the vehicle.
FEV’s PD-HVX utilises established measuring systems with specially developed sensors that are used in EDUs for qualitative measurement. This enables customers to identify partial discharge during the development process and take appropriate countermeasures
“PD has been known for a long time in the field of electrical systems engineering and high-voltage transmission networks, where corresponding tests are common practice,” said Dr. Michael Stapelbroek, Vice President Electric Powertrain at FEV. “In the automotive sector, however, the phenomenon is just gaining focus with the increasing spread of 800-volt batteries. Thanks to our many years of expertise in the development of EDUs, with PD-HVX we can now offer our customers a dedicated solution for PD.”
The solution is designed as part of a comprehensive service package for vehicle OEMs and suppliers, and is optimized for EDU operation, as well as filtering out drive-related interference signals, which “therefore enables significantly better measurement results for PD,” as FEV writes.
