Abstract

A medium-size electric vehicle with a detachable high voltage isolation structure is provided. Due to the detachable high voltage isolation structure, the drawbacks of repairing the high voltage components of the medium-size electric vehicle will be overcome. All of the high voltage components are integrated into the detachable high voltage isolation structure. Consequently, the maintenance worker can repair the medium-size electric vehicle in a safe environment.

Claims
