An experimental study on the failure behavior of high voltage cables (HVCs) under mechanical loading 2020-01-0199

Electrical vehicles have shown a promising future, but the crash safety of high voltage cables (HVCs) used in electrical vehicles has not been given enough attention. This paper presents an experimental study on the failure behaviors of HVCs under different mechanical loadings. Compression tests with three different shapes of indentation head and two loading velocities were conducted. Short circuit between the indentation head and the conductor inside HVCs was monitored. It was found that HVCs exhibited different failure tolerances and failure evolutions when indentation head was different. Indentation head with sharp edges could prematurely induce short circuit severely. Strain rate had a positive effect on the force response. But the influence of strain rate on the failure behavior of HVCs depended on the shape of indentation head.
