Abstract: Abstract IDENTIFICATION OF POLARITY MISMATCH IN HIGH-VOLTAGE CABLE CONNECTIONS OF ELECTRIC VEHICLES 5 10 15 20 The present disclosure describes techniques for checking polarity of electrical connections in an electric vehicle (102). A system (300) comprises a first HV component (108-1) and a second HV component (108-2) electrically interconnected by an HV cable (110). The system comprises a first polarity verification circuit (304-1) configured to establish a first electrical verification path including the HV cable and a second polarity verification circuit (304-2) configured to establish a second electrical verification path including the HV cable. A controller (302) is configured to apply a verification signal to each of the polarity verification circuits and monitor electrical responses from the polarity verification circuits. The controller is further configured to determine, based on the respective electrical responses, whether a polarity mismatch exists in an electrical connection provided by the HV cable and in response to determining that the polarity mismatch exists, inhibit HV energisation of the electric vehicle.
