车载电池（5）如何防起火？

Core Viewpoint - The article discusses the growing concerns regarding electric vehicle (EV) battery fires, despite their lower frequency compared to gasoline vehicles. It highlights the need for technological advancements and regulatory measures to enhance safety and promote EV adoption. Group 1: Causes and Risks of EV Battery Fires - The primary cause of battery fires is "short circuits," which occur when the positive and negative terminals are incorrectly connected, leading to high current and heat generation [3] - Damage to the battery pack from vehicle collisions or foreign objects entering the battery can also cause short circuits, potentially leading to severe losses [3] - A lawsuit has been filed by Mitsui O.S.K. Lines against Porsche, attributing a fire on an automobile transport ship to the EV batteries being transported [3] Group 2: Technological Innovations to Mitigate Fire Risks - The first category of measures involves developing batteries that are less prone to catching fire. 24M Technologies, backed by Itochu Corporation, has created batteries using special insulating materials to reduce short circuit risks [5] - The second category focuses on preventing quality defects that could lead to fires. Japanese companies are applying sensor technologies to detect foreign objects on electrodes, with Konica Minolta developing detection equipment for this purpose [7] - The third category includes improvements to vehicle bodies and battery casings. CATL has developed a vehicle body that ensures battery safety even during high-speed collisions [7] - Renault has patented a technology called "Fireman Access," which enhances the battery casing to allow firefighting water to penetrate the battery more easily in case of a fire [7] Group 3: Regulatory Developments - Various countries are beginning to establish regulations and improve legal frameworks regarding EV battery safety. China is actively revising safety standards for EV batteries [7] - Despite the lower fire frequency of EVs compared to gasoline vehicles, consumer concerns remain significant, necessitating both technological innovation and regulatory development for widespread adoption [7]
