Avoid squeeze zone
For areas that are likely to be crushed with other components, such as the fender area, car jacks, or other lifting tool support areas, high-voltage wiring harnesses should be avoided.
Due to the complex working conditions of the vehicle, in extreme cases, the body will be deformed due to collision and compression.
As the high-voltage wiring harness that carries the power source transmission function of new energy vehicles, when arranging, avoiding the influence of the deformation of the vehicle body should be taken into consideration, and the occurrence of damage and leakage of the high-voltage wiring harness caused by the deformation of the vehicle body should be avoided or reduced as much as possible.
The high-voltage wiring harness should try to avoid being arranged in areas where large deformation will occur after a vehicle collision, such as front and rear anti-collision beams, side wall sheet metal, and front cabin head.
When an electric vehicle collides, it is necessary to consider the displacement path of the high-voltage electrical connection during the energy-absorbing deformation of the vehicle body, so as to avoid the high-voltage wire harness being directly cut by the sheet metal or the metal fragments piercing the insulation layer and entering the wire core to cause high voltage due to vehicle collision. Short circuit, causing electric shock injury to drivers and passengers.
It is required that in a collision without collision detection, the equipotential function must remain active.
