Abstract
The voltage of power circuits used in electric vehicles has increased to 500 V or more. This shift to higher voltages is done to reduce current, harness weight and improve motor-controller's efficiency. The fuses that protect these circuits must shut out DC arcs, yet their performance needs improving. This paper reports the development of a formidable fuse that coats a thin film of hydrogen strage Titanium on copper foil, and its features. This new fuse has shown great potential in protecting high voltage circuits of future electric vehicles, and other high voltage DC electric devices.
