China's NEVs Are Going on a Diet

Published: Jun 10, 2026 11:15
Data shows that in 2024, the average curb weight of China's passenger cars reached 1,704 kg, nearly 400 kg heavier than in 2012. Additionally, around the year 2000, common household NEVs on the market mostly had a width of around 1.7 meters. In 2015, the width increased to 1.8 meters. This week, household vehicles that often weigh close to 2 tons are sparking discussions due to their growing size and weight. Automaker engineers state that for every 10 mm increase in the width of an NEV's auto body, approximately 0.8 kWh more electricity can be packed in. However, experts say that vehicles becoming "fatter" is not solely due to this reason. Experts explain: Some automakers use driving range as a selling point, claiming that their cars can travel 800 or 1,000 kilometers on a single charge. In fact, behind this is the need to install a large battery pack inside the vehicle, which may weigh 700 to 800 kg. On January 1 this year, a mandatory national standard for EVs was officially implemented. For any new car model failing to meet energy consumption standards, the MIIT will not grant registration; the vehicle cannot be produced, sold, or licensed, guiding automakers to curb the growing trend of "obesity" in EVs. In the future, NEVs may hopefully return to standard dimensions.

On June 24, Cangzhou Mingzhu Plastic Co., Ltd. announced that its lithium-ion battery separator production expansion project has been fully completed. This commissioning involves the remaining production lines of the "annual 200 million square meter wet-process lithium-ion battery separator project" and the "annual 500 million square meter dry-process lithium-ion battery separator project." According to the announcement, the second production line (with an annual design capacity of 100 million square meters) under the wet-process project, which is being handled by the subsidiary Wuhu Mingzhu Separator Technology Co., Ltd., has recently commenced production. Concurrently, the remaining three production lines (with a combined annual design capacity of 300 million square meters) under the dry-process project, being handled by the subsidiary Cangzhou Mingzhu Lithium Battery Separator Co., Ltd., have also been completed and put into operation.
