What is the waterproof rating of BYD?
2 Answers
BYD's pure electric version core components can meet the IP76 standard. Short-term wading is not a problem, but generally the wading depth should not exceed half of the vehicle's wheel hub, as there are other circuits inside the car. New energy electric vehicles with IP67 waterproof rating can drive normally in 40CM deep water. IP76 waterproof level: IP76 level (IP stands for Ingress Protection Rating) refers to the protection safety level. The first digit after IP indicates the solid protection level, and the second digit indicates the liquid protection level. This level of waterproofing should ensure no issues when submerged in one meter of water for half an hour. The one-meter water depth here does not refer to the road surface water depth, but the water depth covering the electronic devices, which is roughly equivalent to the situation where the car is completely submerged in water. The necessity of waterproofing: For electric vehicles, how to handle waterlogged sections during driving and whether the vehicle's performance and safety will be affected after encountering water have become focal points of concern. The main components of electric vehicles consist of three parts: motor, battery, and electronic control. There is concern that once high-voltage working parts such as the battery and motor of an electric vehicle are flooded, leakage and short-circuit issues may occur.
The waterproof ratings vary significantly among different BYD models, mainly depending on the battery pack protection level. The battery packs in flagship models like the Han EV have achieved an IP67 rating, meaning they can withstand immersion in one meter of water for half an hour with no issues, making them fully capable of handling heavy rainstorms. The Yuan PLUS uses an IP66-rated battery, which provides sufficient protection against high-pressure water jets. However, the top-tier performance belongs to newer models like the Seal, whose battery packs directly reach IP68 level, meaning even severe flooding is unlikely to penetrate their core battery areas. That said, the vehicle's overall protection level is generally IP67, with excellent sealing for all high-voltage components. Still, it's worth reminding that no matter how waterproof an electric vehicle is, avoid driving through deep water—manufacturer standards are based on static conditions.
