1064小时防腐测试的冷却液，渗透了理想MEGA的电池

Core Viewpoint - The article discusses the recall of approximately 11,000 units of the Li Auto MEGA 2024 model due to a safety hazard related to the coolant, which may corrode critical components and potentially lead to battery thermal runaway and fire incidents [3][4]. Group 1: Recall Details - Li Auto announced a recall of about 11,000 MEGA 2024 models to replace the coolant, battery, and front motor controller due to insufficient corrosion resistance of the coolant [3][4]. - The recall was prompted by concerns that under specific conditions, the coolant could corrode the aluminum cooling plates of the battery and front motor controller, leading to short circuits and fire risks [3][4]. Group 2: Industry Concerns - Industry professionals raised questions about the quality control measures in place, especially given that the vehicles were less than two years old and such corrosion issues are uncommon [4][8]. - The article highlights the importance of quality control awareness among automakers, emphasizing that thorough safety inspections should be conducted at every stage of vehicle production to prevent costly post-sale remedies [4][8]. Group 3: Coolant Specifications - The article explains that electric vehicle coolant is a functional liquid composed of antifreeze and corrosion inhibitors, designed for thermal management of the battery system [6][7]. - The coolant used in electric vehicles is more complex than that in traditional vehicles, requiring higher standards due to its role in cooling multiple components [7][8]. Group 4: Testing and Standards - The article outlines the stringent testing requirements for electric vehicle coolants, including static and cyclic corrosion tests, which must meet specific quality metrics [8][10]. - Despite these rigorous standards, the article questions why the Li Auto MEGA's coolant failed to meet corrosion performance expectations, suggesting a need for further investigation into the testing and quality assurance processes [10][12]. Group 5: Market Dynamics - The article notes that the electric vehicle market is experiencing intensified competition, leading to compressed testing cycles and accelerated product launches, which may compromise safety and quality [12][13]. - Li Auto's rapid product development timeline, from trademark registration to market launch within a year, exemplifies the industry's trend of prioritizing speed over thorough testing [13].
