Short-circuit testing for electric vehicles: qualification of fuses and EV components

Le prove di corto circuito per veicoli elettrici servono a verificare la capacità dei sistemi in corrente continua di resistere a stress energetici estremi senza generare rischi termici o meccanici.
Short-circuit testing for electric vehicles: qualification of fuses and EV components

The laboratory's high-power infrastructure employs a 7.5 MVA transformer that enables the generation of stable stresses and the delivery of test currents up to 16 kA at 1000 Vdc. INTEK technicians record energy transients using high-frequency synchronized digital measurement chains, verifying the breaking capacity and the dynamic behavior of materials subjected to stress. The tests are carried out in compliance with the special specifications of manufacturers, applying rigorous safety standards to objectively quantify the immediate thermal impact on conductive parts.

The availability of certified experimental data allows for unequivocally validating the reliability of automotive protection systems. Successfully passing the tests for the qualification of fuses and EV components enables designers to optimize the safety margins of materials, eliminating the risk of late-stage redesigns. The certified metrological approach drastically reduces technical qualification times and ensures the introduction of compliant and safe components to the global market.
