Usually the batteries of new energy vehicles (NEV) are under a warranty of eight years. From 2025 to 2032, battery warranties of nearly 20 million NEVs had or will run out, which leads users to issues including driving cars with unwarranted batteries, lifespan difference between the vehicle and the battery, and quite high battery replacement costs.
Retired power batteries should be tested and selected in order to meet the requirements of echelon utilization. Chen L proposed a new lithium-ion battery performance degradation model to predict its capacity decay, resistance increase and residual cycle life under various service modes [ 16 ].
Echelon utilization occasions of power batteries at different capacity stages. Normal use stage: the battery capacity is 80–100%; that is, the power battery meets the use requirements of electric vehicles, and is used in the vehicle as a normal energy battery; The first stage of echelon utilization: the battery capacity is 60–80%.
China is carrying out pilot recycling of new-energy vehicle power batteries, promoting enterprises such as automobile manufacturing, battery production and comprehensive utilization, to carry out echelon utilization tests in the fields of power reserve and energy storage, and to explore new business models.
China’s current standard for vehicle battery power is that the capacity attenuation should not exceed 20% of the rated capacity within 8 years or 120 thousand kilometers. Therefore, the service life of power batteries is relatively short, usually only 5–8 years, and their effective life can even be as short as 4–6 years.
In addition, with regards to battery R&D, NIO has significantly improved the calendar life and cycle life of batteries via research and development focusing on the intrinsic properties of anode and cathode materials as well as electrolyte.
