100万辆车电池包“零自燃”！背后究竟藏了什么技术？

Core Viewpoint - Huawei has rapidly become a leading supplier in the automotive industry, leveraging its advanced technology in both electrification and intelligent systems, particularly through its HarmonyOS and ADS solutions [2][4][5]. Group 1: Huawei's Battery Technology - Huawei's battery technology, particularly the Whale Battery platform, has achieved significant milestones, including the installation of over 1 million units and the production of 150 million battery cells since the launch of the first model in 2021 [8]. - The Whale Battery has maintained a record of zero safety incidents related to battery pack thermal runaway or cell quality issues, addressing a major concern in the electric vehicle industry [9][15]. - The Whale Battery employs innovative techniques such as the "Overhang" technology to suppress lithium dendrite growth, enhancing battery safety by increasing the negative electrode's capacity [25][26][30]. Group 2: Thermal Management and Safety Features - The Whale Battery platform incorporates advanced thermal insulation materials, creating a "safety house" around each cell to prevent thermal runaway from spreading [37][40]. - A unique design feature includes a downward-facing explosion valve to safely release high-temperature gases, minimizing risks to vehicle occupants [44][46]. - The platform also utilizes a large-area liquid cooling system to manage heat generated during charging and discharging, further enhancing safety [49]. Group 3: Structural Integrity and Protection - The Whale Battery package is designed with rigorous insulation and waterproofing measures, capable of withstanding extreme conditions, including heavy rain and high-pressure washing [56][57]. - Physical protection is reinforced with aluminum alloy plates and high-strength steel to resist external impacts, ensuring durability [60]. Group 4: Optimization and Efficiency - The Whale Battery package reduces complexity by consolidating wiring into a "wire harness high-voltage box," minimizing potential safety hazards from manual assembly errors [67]. - The Battery Management System (BMS) features cloud communication capabilities for real-time monitoring and alerts, enhancing battery health management [71][72]. Group 5: Commitment to Safety Standards - Huawei's approach to battery technology is rooted in a long-standing commitment to safety, informed by experiences in other technology sectors [78][81]. - The company has proactively engaged with regulatory bodies to ensure compliance with safety standards, achieving a level of safety that exceeds current national requirements [83][84].
