In order to improve the airtightness, safety, comfort and corrosion resistance of the passenger cabin on an electric vehicle, the paper analyzed and studied the problem of water intake in the passenger cabin of an electric vehicle in wading test. By recording all water intake points, find their water inlet path and causes, and classify them, including the bug problems of lack easy glue by reason of body structure design, the no hermetic problems of pipeline and wiring harness clip matching hole, and deficiency hermetic disposal problems after opening channels holes etc. Then, the concrete solutions are presented for every problems. For example, the filling area for coating, the fixing point of lines and pipelines shall replace the buckle holes with welding studs, improve the enclosure sealing structure under the gear changer, improve the structure of the steering column protector and the sealing rubber pad in the air conditioning pipe passing through the holes shall replace the sponge pad. The paddle test is performed again, water cannot enter passenger compartment. Result indicated that daubing all welding line glue, reducing hole and do well hermetic disposal after opening hole for body structure which have hermetic request, can prevent water in letting passenger compartment efficaciously.
