What are the causes of the whole vehicle insulation failure in the BAIC EU5 R500?
1 Answers
Here are the reasons for the whole vehicle insulation failure in the BAIC EU5 R500: 1. Battery electrolyte leakage: The electrolyte is dilute sulfuric acid, which can corrode the vehicle body and other equipment. After the single-cell liquid is completely leaked, the electrode plates are directly exposed to air, causing oxidation of the plates and shortening the battery's service life. 2. External liquid ingress: After the battery system is submerged, gas is generated due to the electrolysis of water reaction. The movement of high-pressure connected gas produces switching, causing arcing at the connection points. If fully submerged, the arcing may cause a battery fire. 3. Formation of conductive circuits: After the insulation layer is damaged, conductive circuits appear between battery modules and cells, causing short circuits and resulting in whole vehicle insulation failure.
