Research On the Forecasting of Sales Volume of New Energy Vehicles Based on SARIMA Model

In recent years, the new energy vehicle market has experienced rapid growth due to policy support and environmental enhancements; however, sales volume fluctuates due to various factors, making precise forecasting essential for production planning, supply chain management, and market strategy. This paper conducts a comprehensive forecasting analysis of new energy vehicle sales volume utilizing the SARIMA model, including the fluctuations in the worldwide new energy vehicle industry. The research gathers and preprocesses monthly sales volume data of new energy cars from January 2022 to April 2024 and develops a SARIMA prediction model by thoroughly considering the trend, seasonal, abrupt, and stochastic error components. The projections indicate that the sales volume of new energy cars will attain 478,000 units in May 2024, increase to 883,000 units in June, and see a minor decline to 588,000 units in July, while still being elevated. This particular numerical conclusion offers a scientific foundation for the future advancement of the new energy vehicle market and is highly significant in directing the optimal placement of charging facilities, assessing the adequacy of existing charging infrastructure, and recommending optimal locations for charging station installations.
