With the development of new energy vehicles to higher voltage platform, such as 800V high voltage platform, higher requirements are put forward for the rated voltage and current level of fuse. High voltage fuse needs to have higher rated voltage, to ensure matching with the system, while keeping not less than line voltage, to avoid overvoltage failure.

[0003] In the automobile high voltage system, high voltage fuse can cut off the circuit at the early stage of failure, limit the fault in a small range, prevent the fault from further expanding, thereby improving the reliability and stability of the whole high voltage system, reducing the vehicle stop and maintenance cost caused by failure. When high voltage fuse is fused, maintenance personnel can easily find this obvious failure indication and quickly locate the fault circuit or component. Replace the fuse in this part, which helps to shorten the fault diagnosis time, facilitate after-sales maintenance and spare parts replacement, improve maintenance efficiency, and make the vehicle resume normal use faster.
