University of Texas at Dallas researchers have developed a first-of-its-kind technology to detect and reduce “noise” from electromagnetic interference (EMI) in electric vehicles. Electric vehicles (EVs) contain a large number of electrical components packed into small areas. “If a device in an electric vehicle fails, the results could be catastrophic,” said Lixiong Du, an electrical engineering doctoral student who led the research. “In order to convert the energy from the battery to power the systems, you need hundreds of power circuits. That sensor is the first to be able to test aging inside a computer chip and in its casing.
