Core Viewpoint - The article discusses the public solicitation of opinions on two automotive industry standards related to electric vehicle battery thermal characteristics and sodium-ion batteries, highlighting the importance of these standards for the development and safety of electric vehicles [3][5][7]. Group 1: Electric Vehicle Battery Thermal Characteristics - The draft standard for "Thermal Characteristics Testing Methods for Electric Vehicle Power Batteries" includes seven chapters covering scope, normative references, terminology, testing conditions, methods, data recording, and reporting [5]. - Thermal characteristics such as entropy heat coefficient, specific heat capacity, thermal conductivity, and heat generation power are critical for evaluating battery performance and safety, impacting energy conversion efficiency and operational lifespan [5][6]. - The standard aims to provide a systematic and scientific testing reference for vehicle manufacturers, battery companies, and testing institutions, ensuring accurate test results and reducing risks in thermal management design [6][10]. Group 2: Sodium-Ion Battery Standards - The draft standard for "Sodium-Ion Batteries for Electric Vehicles" consists of six chapters detailing scope, normative references, terminology, technical requirements, and testing methods [7]. - Sodium-ion batteries are emerging as a cost-effective alternative with good low-temperature performance and high safety, necessitating the establishment of specific standards due to the lack of existing regulations [7][8]. - The Ministry of Industry and Information Technology emphasizes the importance of developing standards for sodium-ion batteries to support their integration into the electric vehicle market and ensure quality and safety [8][10]. Group 3: Expected Social Benefits - The establishment of these standards will support industry management by providing a unified regulatory basis for the sodium-ion battery sector, ensuring its standardized development [8][9]. - Standardized testing methods will enhance product quality and safety, reducing the risk of safety incidents caused by battery thermal runaway [8][9]. - The standards will promote fair market competition by standardizing testing protocols, preventing market confusion due to inconsistent standards [9][10].
