Abstract

As electric vehicles (EVs) emerge as the backbone of modern transportation, the concurrent uptick in battery fire incidents presents a disconcerting challenge. To tackle this issue effectively, it is imperative to pierce beyond the superficial causes of lithium-ion battery (LIB) failures—such as equipment malfunctions or physical damage—and to excavate the underlying triggers. This nuanced approach is pivotal to refining EV quality, diminishing fire incidents, and bolstering consumer trust. While issues that are readily apparent to consumers, like spontaneous battery degradation, vehicular collisions, or submersion, may seem like the primary culprits, they merely scratch the surface of a more complex problem. The true mechanisms behind these fires involve internal and external short circuits, yet these explanations fall short in providing actionable guidance for manufacturers or end-users to enhance LIB safety. The heart of the issue is identifying the root causes that bridge failure triggers and resulting fires. A total of 20 root causes are identified, linking them to real-world scenarios like overcharging causing internal shorts or wire harness issues leading to external shorts. With this insight, stakeholders can more effectively investigate and understand EV LIB fire incidents, bolstering EV safety and reliability, and promoting consumer confidence.

追踪电动汽车火灾的根本原因
随着电动汽车(ev)成为现代交通的支柱,与此同时,电池火灾事件的增加提出了一个令人不安的挑战。为了有效地解决这一问题,必须突破锂离子电池(LIB)故障的表面原因,如设备故障或物理损坏,并挖掘潜在的触发因素。这种细致入微的方法对于提高电动汽车质量、减少火灾事故和增强消费者信任至关重要。虽然对消费者来说,电池自发退化、车辆碰撞或淹没等显而易见的问题似乎是主要的罪魁祸首,但它们只是触及了更复杂问题的表面。这些火灾背后的真正机制涉及内部和外部短路,但这些解释不足以为制造商或最终用户提供可操作的指导,以提高LIB的安全性。问题的核心是找出桥梁故障引发火灾的根本原因。总共确定了20个根本原因,将它们与现实世界的情况联系起来,例如过度充电导致内部短路或线束问题导致外部短路。有了这种洞察力,利益相关者可以更有效地调查和了解电动汽车起火事件,提高电动汽车的安全性和可靠性,并提高消费者的信心。

期刊介绍: Energy Technology provides a forum for researchers and engineers from all relevant disciplines concerned with the generation, conversion, storage, and distribution of energy. This new journal shall publish articles covering all technical aspects of energy process engineering from different perspectives, e.g., new concepts of energy generation and conversion; design, operation, control, and optimization of processes for energy generation (e.g., carbon capture) and conversion of energy carriers; improvement of existing processes; combination of single components to systems for energy generation; design of systems for energy storage; production processes of fuels, e.g., hydrogen, electricity, petroleum, biobased fuels; concepts and design of devices for energy distribution.
