AI Customer ServiceFor example, LIBs for energy-based scenarios should be classified based on the capacity and remaining life. LIBs for power-based scenarios should be classified based on the internal resistance and remaining life. Therefore, the battery classification can be simplified into a two-dimensional classification problem.
We define EV battery utilization rates as the percentage of battery energy utilized for driving. By employing the strong linear relationship between consumed battery energy and driving distances in statistics (SI Appendix, Fig. S18), we transform the calculation of battery energy usage into that of the driving range usage.
For energy–power application scenarios, batteries should be classified based on the capacity, internal resistance, and remaining life. This is a three-dimensional classification problem, which can be easily solved with algorithms such as support vector machines.

Therefore, the battery classification can be simplified into a two-dimensional classification problem. For energy–power application scenarios, batteries should be classified based on the capacity, internal resistance, and remaining life.
The bus energy consumption is calculated based on the new battery size (effectively the new bus weight). The process is repeated until the battery size converges to a certain value, defined as less than 1 % change in battery size for any 2 consecutive iterations. 3. Case study 3.1. Data sources
