New Energy Vehicles Set for 8-Year Quality Assurance Period; Power Battery Undergoes “Pressure Test”
As of April 23, 2025, the new energy vehicle industry in China will implement an 8-year quality assurance period for power batteries, a move aimed at enhancing consumer confidence in electric vehicles. The requirement for a robust battery system has become increasingly important to support the growing demand for new energy vehicles.
In a report released by the China Petroleum and Chemical Industry Report in early April, it was revealed that the battery capacity of electric vehicles is facing significant challenges. According to the latest data from the China Automobile Industry Association, in the first quarter of this year, sales of new energy vehicles reached 3.182 million units, a 50.4% increase compared to the previous year. This growth indicates that new energy vehicles now account for 41.2% of total vehicle sales.
However, the industry has also faced ongoing issues related to battery degradation, which has impacted the operational efficiency of electric vehicles. Since 2015, the Ministry of Industry and Information Technology has set a standard requiring that new energy vehicles must maintain a battery capacity of at least 80% after 8 years or 120,000 kilometers of use. Currently, the quality assurance period has been fulfilled.
According to vehicle app data, the number of new energy vehicles is expected to reach 320,000 by the end of this year, 980,000 by 2028, and 720,000 by 2032. Over the next eight years, the total quantity of new energy vehicles in China is expected to surpass 2 million units.
To meet this quality assurance period, manufacturers must ensure that the battery systems are adequately monitored and maintained. However, the costs associated with high-performance batteries have increased significantly, making it challenging for some manufacturers to comply.
As of October 2024, the 18th Power Battery Symposium will present data indicating that among 59 pure electric vehicles, the energy density of power batteries will reach 50.96%, with the price per kilowatt-hour expected to be around 1604.92 yuan.
For example, a sedan with a 73.6-kilowatt battery will require 11.8 million yuan for battery replacement. Meanwhile, the average price of this vehicle is around 250,000 yuan, with battery costs constituting 40% of the total price.
To mitigate issues surrounding battery lifespan, some manufacturers are exploring strategies to enhance battery performance and longevity. However, high costs related to battery production remain a significant barrier for many consumers.
The ongoing promotion of new energy vehicles also includes a focus on the collaborative development of battery technology to improve quality and reliability. Manufacturers are encouraged to share information and resources to address these challenges effectively.
In summary, while the transition to new energy vehicles presents opportunities for growth, it also requires a concerted effort to ensure battery quality and performance are prioritized to satisfy consumer expectations and regulatory requirements.
