刚陷“起火门”，理想便紧急召回11411辆MEGA

Core Viewpoint - Li Auto has initiated a recall of 11,411 units of its MEGA 2024 electric vehicle due to insufficient corrosion resistance of the coolant, which may lead to battery and motor controller failures, posing safety risks [1][2]. Group 1: Recall Details - The recall affects vehicles produced between February 18, 2024, and December 27, 2024, and includes free replacement of coolant, battery, and motor controller for the affected units [1]. - The recall follows a recent incident where a Li MEGA vehicle caught fire while driving, raising public concerns about the safety of electric vehicle batteries [2][4]. Group 2: Incident Analysis - The fire incident involved a Li MEGA vehicle that experienced a loud explosion sound from the chassis, followed by smoke filling the cabin, leading to a successful escape by the occupants [4]. - This incident is part of a broader discussion on the safety of electric vehicle batteries, especially as the market for electric vehicles continues to grow [4]. Group 3: Technical Insights - The fire's cause remains undetermined, but potential factors include short circuits in battery components and failures in the battery management system (BMS) [5][9]. - The complexity of battery systems makes it challenging to pinpoint exact causes of incidents, as multiple factors can contribute to failures [7][10]. Group 4: Regulatory Changes - A new national standard for electric vehicle batteries, set to be implemented in July 2026, aims to enhance safety testing protocols, addressing gaps in current regulations [11][14]. - The new standard includes rigorous testing for thermal diffusion, impact resistance, and fast charging cycles, which were not adequately covered by previous regulations [11][16]. Group 5: Industry Trends - The industry is moving towards high energy density and ultra-fast charging technologies, which present new safety challenges that need to be addressed [15][16]. - Companies are encouraged to align their performance claims with actual safety data to avoid misleading consumers and ensure transparency in testing conditions [16].
