部分电车重达3吨、堪比轻卡，经济日报：新能源汽车该减肥了

Core Viewpoint - The implementation of the new national standard for electric vehicle energy consumption marks a significant regulatory shift aimed at reducing the weight of electric vehicles and promoting technological upgrades among manufacturers [2][4]. Group 1: New Standards and Regulations - The new standard is the world's first mandatory energy consumption limit for electric vehicles, designed to curb the increasing weight of electric cars and enforce stricter technical upgrades [2]. - The standard has tightened energy consumption limits by approximately 11% compared to the previous recommended standard, accommodating diverse vehicle types while pushing for a shift from a "large battery for long range" model to a "high efficiency, low energy consumption" approach [4]. Group 2: Industry Trends and Challenges - Data from the China Association of Automobile Manufacturers indicates that by 2025, the production and sales of new energy vehicles in China are expected to reach 16.626 million and 16.49 million units, respectively, representing year-on-year growth of 29% and 28.2% [2]. - The trend of increasing vehicle weight is primarily driven by the practice of "blindly stacking batteries" to achieve longer ranges, which can lead to significant increases in vehicle weight and production costs [3]. - The push for electric vehicles to serve as "mobile ecological spaces" has led to the addition of comfort and technology features, further contributing to weight increases [3]. Group 3: Implications of Increased Vehicle Weight - Heavier vehicles require more energy to operate, often resulting in actual range falling short of theoretical values, and can negatively impact handling, braking safety, and overall driving experience [3]. - The new standard includes a transitional mechanism that allows existing models a two-year buffer period to comply with the new energy consumption limits, ensuring manufacturers have time to adapt [5]. Group 4: Future Directions - The new regulations are expected to drive companies to increase R&D investments in key areas such as lightweight design, electric drive system efficiency, and thermal management technology, as well as to explore cutting-edge technologies like solid-state batteries [5]. - The goal is to enhance energy efficiency and provide consumers with a more economical and reliable green travel experience, emphasizing the need for electric vehicles to "lose weight" [5].
