Causes of high voltage insulation failure of Chery Airuizeyuan automobile

Hello, I would like to ask what is the cause of the high-voltage insulation failure of Chery Arrizeyuan automobile? The reason for the failure of high-voltage insulation of Chery Arrizeyuan automobile is that the insulation resistance of high-voltage part is too low. The insulation resistance of the high-voltage part of Chery Ariza source automobile is too low, and BMS detection and protection limit the running with electricity, so the high-voltage insulation failure of Chery Ariza source automobile is caused by the low insulation resistance of the high-voltage part.
