Can a New Energy Vehicle Start After Being Submerged in Water?

[MacTanner]

New energy vehicles may or may not start after being submerged in water. Methods for dealing with different levels of water submersion: When designing the three-electric system, new energy vehicles fully consider the importance of sealing functions, with a sealing level generally rated at IP67. In power battery testing, the battery is required to be fully charged and then completely submerged in a 3.5% sodium chloride solution for 2 hours, followed by an observation period of 1 hour to ensure no fire or explosion occurs. Therefore, theoretically, new energy vehicles can withstand being submerged in water. Methods for dealing with minor water submersion: If the submersion is not severe and there is no water in the engine compartment, drive to a repair shop as soon as possible to clean the chassis and perform ventilation treatment. However, during actual water submersion, the power battery is usually installed at the vehicle's chassis position, and the water often contains a large amount of sand and impurities. The road conditions underwater are also difficult to assess, making it easy for foreign objects to damage the vehicle's insulation and sealing layers. Thus, safety during actual water submersion is hard to guarantee.
