理想回应MEGA自燃，主动召回11411辆汽车

Core Viewpoint - Beijing Li Auto Co., Ltd. has proactively filed a recall plan with the State Administration for Market Regulation, recalling 11,411 units of the 2024 MEGA model due to safety concerns related to a fire incident that occurred on October 23 in Shanghai [1][4][6]. Group 1: Recall Details - The recall will affect all MEGA vehicles sold in 2024, with sales data indicating approximately 11,000 units sold [2]. - The recall is set to begin on November 7, 2025, covering vehicles produced between February 18, 2024, and December 27, 2024 [1]. Group 2: Incident Background - The recall is linked to a fire incident involving the 2024 MEGA, where the owner managed to escape without injury [4]. - Li Auto has been in contact with the vehicle owner and is cooperating with relevant authorities for an investigation, which is still ongoing and has not yet reached a technical conclusion [4]. Group 3: Safety Concerns - Internal investigations revealed that the coolant's anti-corrosion performance was inadequate, potentially leading to corrosion and leakage in the cooling system, which could cause warning lights to illuminate, power limitations, or even thermal runaway of the battery under extreme conditions [5]. - As a response, Li Auto will replace the coolant, battery, and front motor controller for the recalled vehicles at no cost [6]. Group 4: Battery Technology Insights - The 2024 MEGA is the first flagship electric vehicle from Li Auto, featuring the CATL Kirin 5C battery, which emphasizes fast charging as a key selling point [8]. - The battery technology landscape includes three main routes: high-nickel ternary batteries for high-end models, cost-effective nickel-based batteries, and lithium iron phosphate batteries for more affordable models [9][10]. - The choice of battery materials impacts safety and performance, with lithium iron phosphate batteries being more thermally stable but less effective in cold conditions, while ternary lithium batteries offer faster conductivity but at a higher cost and lower thermal stability [10]. Group 5: User Safety Measures - Li Auto has introduced emergency measures for users, including a cloud-based warning system that alerts users to potential coolant leaks and provides assistance through customer service [11]. - Users will receive notifications through the vehicle's system if any faults occur, advising them to pull over and await assistance [11].
