Core Viewpoint - The recent claims that electric vehicles (EVs) are unsafe to drive in rainy conditions due to electric shock risks have been debunked by experts, emphasizing that EVs are designed with adequate waterproofing and safety measures [1][11]. Group 1: Battery Design and Safety Standards - Electric vehicle batteries are generally designed with IP67 or higher waterproof ratings, ensuring they remain intact even when submerged for a limited time, thus eliminating leakage risks [2][8]. - According to national standards, all marketed EVs must pass rigorous water immersion tests, including driving in 100mm deep water at specified speeds for a minimum distance [4]. - The national standard for power batteries mandates that all batteries must meet mechanical vibration durability tests followed by water immersion tests [5]. Group 2: Safety Mechanisms and Expert Insights - Experts highlight that EVs are equipped with multiple safety mechanisms that automatically disconnect high-voltage power in case of detected anomalies, ensuring safety during normal operation [9]. - While driving in heavy rain or flooded areas poses general driving risks, it does not specifically relate to electric shock concerns, allowing for safe operation of EVs in such conditions [11]. - Charging an EV in rainy weather is not as dangerous as commonly perceived, as the charging process begins in a disconnected state, ensuring safety checks are in place before high-voltage current is activated [13]. Group 3: Precautions for Charging in Rainy Conditions - To ensure safety while charging during heavy rain, EV owners should take precautions such as selecting appropriate charging locations, avoiding waterlogged charging stations, and following proper operational guidelines [15].
