Core Viewpoint - The recent discussions surrounding the safety responsibilities of power batteries have become a focal point in the industry, particularly following a global recall initiated by an international automaker in early 2026, which has drawn attention to the battery supply chain [1] Group 1: Battery Safety and Responsibility - The recall event has prompted deeper reflections on the boundaries of responsibility within the supply chain, especially as battery failures and safety incidents have become more frequent amid the rapid growth of new energy vehicle ownership [1] - A lawsuit was filed against a battery supplier, XWANDA, by a domestic automaker claiming quality issues with the supplied battery cells, seeking over 2.3 billion yuan in damages [3] - XWANDA emphasized that the battery system issues cannot be solely attributed to the battery cells without comprehensive technical validation, highlighting the complexity of the battery pack as a system [3] Group 2: Market Position and Performance - XWANDA holds a significant position in the industry, with a reported domestic new energy passenger vehicle installation volume of 21.32 GWh and a market share of 3.93% for the period from January to November 2025, marking an increase of 0.57 percentage points year-on-year, ranking fifth [3] - Globally, XWANDA's battery installation volume is projected to reach 18.8 GWh in 2024, representing a year-on-year growth of 74.1%, with a market share of 2.1%, ranking tenth [3] Group 3: Systematic Analysis of Battery Failures - Analysts suggest that the analysis of battery failures should encompass three parts: full lifecycle data tracing, systematic verification of components, and cross-comparison of performance across different battery pack designs [4] - Responsibility for failures may stem from various factors, including manufacturing defects in battery cells, unreasonable BMS overcharge protection logic, insufficient coolant flow, or excessive vibration loads at installation points [4] Group 4: Collaborative Development Model - The industry is urged to shift from a simple "parts procurement" and "post-factum accountability" approach to a "pre-collaborative development" model to ensure the safety and reliability of batteries [6] - An example of this model is XWANDA's collaboration with a new energy vehicle company, where both parties formed a joint team from the early stages of vehicle definition to ensure compatibility and consistency between battery cell characteristics and system requirements [6] Group 5: Call for Industry Standards - The recent events surrounding XWANDA have highlighted the need for a "joint responsibility sharing agreement" within the industry, advocating for a shift from post-event accountability to proactive collaboration to prevent technical risks [8] - Industry organizations are encouraged to establish standard processes for attributing technical issues, ensuring a neutral stance until third-party testing and judicial conclusions are reached, while also enhancing data collection and sharing throughout the battery lifecycle [8]

Core Viewpoint - The recent discussions surrounding the safety responsibilities of power batteries have become a focal point in the industry, particularly following a global recall initiated by an international car manufacturer in early 2026, which has drawn attention to the battery supply chain [1]. Group 1: Battery Safety and Responsibility - The recall incident has prompted deeper reflections on the boundaries of supply chain responsibility, especially as battery failures and safety incidents have been on the rise amid the rapid growth of new energy vehicle ownership [1]. - A domestic car manufacturer filed a lawsuit against XINWANGDA, claiming quality issues with the supplied battery cells, seeking compensation exceeding 2.3 billion yuan. XINWANGDA responded that the third-party testing and judicial processes are not yet complete, emphasizing the need for a comprehensive technical validation rather than attributing battery system issues solely to the battery cell segment [4]. - XINWANGDA's market position is significant, with a domestic new energy passenger vehicle installation volume of 21.32 GWh and a market share of 3.93% in the first 11 months of 2025, reflecting a year-on-year increase of 0.57 percentage points, ranking fifth in the industry [4]. Group 2: Systematic Analysis of Battery Failures - A systematic approach to fault attribution is necessary, which includes full lifecycle data analysis from battery cell production to failure, systematic verification of BMS control strategies, and cross-comparison of performance across different battery pack designs [5]. - The responsibility for battery failures may lie in various components, including manufacturing defects in battery cells, unreasonable BMS overcharge protection logic, insufficient coolant flow leading to localized overheating, or excessive vibration loads at installation points [5]. Group 3: Collaborative Development Models - The collaboration model between vehicle manufacturers and battery suppliers must shift from simple "parts procurement" and "post-factum accountability" to a "pre-collaborative development" model to ensure the safety and reliability of batteries [8]. - An example of this is XINWANGDA's partnership with a new energy vehicle manufacturer, where both parties formed a joint team from the early stages of vehicle definition, ensuring that battery cell characteristics align perfectly with BMS control strategies and thermal management needs [9]. Group 4: Industry Call for Responsibility Sharing - The recent public relations incident involving XINWANGDA has highlighted the need for the industry to establish a "shared responsibility agreement" and to promote the "joint venture" model to shift accountability from post-event to preemptive measures through deep collaboration [11]. - The industry should develop standard processes for attributing technical issues, ensuring that all parties maintain a neutral technical stance until third-party testing reports and judicial conclusions are released, while also enhancing the collection and sharing of battery lifecycle data to provide a reliable data foundation for scientific attribution [11].
