涉及电池、续航等关键问题 一系列新能源汽车测试结果如何？

Group 1 - High-temperature testing is a crucial aspect of research and quality control in the electric vehicle industry, with significant testing being conducted in Turpan, Xinjiang, where extreme temperatures can reach 50°C [1] - The China Automotive Technology Research Center has introduced new equipment for summer testing, including a self-developed air conditioning dummy that simulates in-vehicle comfort under high-temperature conditions [1] - The dummy is equipped with 50 sensors distributed across 16 body parts to collect environmental data such as temperature, humidity, and radiation, allowing for accurate evaluation of cabin thermal comfort [1] Group 2 - Concerns regarding battery overheating and range degradation under high-temperature conditions are paramount for freight drivers, prompting the use of intelligent temperature control systems in electric vehicle batteries [1] - Testing engineers reported that during a high-temperature performance test, the battery temperature remained within optimal performance range even after three hours of continuous driving and charging for ten minutes with air conditioning on [1] - Summer driving conditions, including direct sunlight and high-temperature road surfaces, can lead to tire rubber softening and gas expansion, increasing the risk of blowouts [2] Group 3 - Testing scenarios simulate tire blowouts during straight driving, lane changes, and turns to assess vehicle stability and safety design under sudden loss of balance [2] - Heavy rainfall poses additional safety challenges, with tests conducted to evaluate vehicle performance when driving through water depths of 40 to 50 centimeters, including checks on battery sealing and high-voltage system safety after forced power disconnection [2]
