Core Viewpoint - The article discusses the public solicitation of opinions on the draft industry standard for "Supercapacitors for Electric Road Vehicles," which aims to enhance the quality and safety of supercapacitors in the electric vehicle sector [1][2]. Summary by Sections Introduction - The National Automotive Standardization Technical Committee has released a draft for the industry standard on supercapacitors, inviting public feedback until July 3, 2025 [1]. Background - Supercapacitors serve as a new type of energy storage device, bridging traditional electrolytic capacitors and batteries, and are increasingly used in electric vehicles due to their high power and rapid charging characteristics [2]. Changes in Terminology and Definitions - The new standard replaces QC/T 741—2014 and introduces several new terms while removing outdated ones, such as "water-based supercapacitor" and "organic supercapacitor" [3]. Technical Requirements - The standard specifies requirements for the appearance, polarity marking, dimensions, quality, electrical performance, voltage retention, temperature characteristics, cycle life, and safety of supercapacitors and their systems [4]. Testing Methods - Detailed testing methods for supercapacitors and their systems are outlined, with significant changes in static capacitance testing, low-temperature performance testing, and safety testing methods [5]. Expected Social Benefits 1. Enhancing Industry Technology Level: The introduction of new classifications for supercapacitors is expected to guide companies in optimizing product design and improving material and process standards [6]. 2. Improving Electric Vehicle Safety: New safety requirements for supercapacitor systems align with existing battery safety standards, enhancing consumer protection [6]. 3. Promoting Energy Conservation and Emission Reduction: The revised standard aims to improve the efficiency of supercapacitors in electric vehicles, supporting China's dual carbon goals and enhancing the competitiveness of the domestic industry [7].
