AI Technical Summary
Technical Problem
Existing vehicles with breathing films in battery packs face challenges in preventing water ingress when driving on flooded roads.
Method used
The vehicle design includes a battery pack housed in a battery case and an inverter housed in an inverter case, connected by a tube with a breathing membrane positioned higher than the battery case, allowing ventilation between the internal spaces and using connectors with through-holes to connect these spaces, thereby minimizing water contact with the breathing membrane.
Benefits of technology
This configuration effectively prevents water from contacting the breathing membrane during flooded road travel, maintaining vehicle integrity and functionality without narrowing the interior space.
