In recent years, the new energy vehicle market has been developing rapidly, in order to further increase the competitiveness of new energy vehicle market, effectively reduce the risk of users and the initial purchase cost, many car companies have launched the battery rental mode of vehicle purchase. Currently, the physical non-interchangeable passenger car occupies a large market share in the battery rental mode, so this paper focuses on the economics of the physical non-interchangeable passenger car in the battery rental mode. From the perspective of consumer cost of ownership, the total cost of ownership (TCO) method is utilized to compare the three options of purchasing a fuel vehicle, purchasing a new energy vehicle as a whole, and purchasing a new energy vehicle in the battery leasing mode, and to obtain the optimal rental pricing range that is a win-win situation for both consumers and battery operators. From the perspective of profitability of battery operators, we establish economic indicators of income and assets, and comprehensively evaluate the economic impacts of rental pricing, residual value of batteries, body scrap ratio, and the ratio of sales volume and model selection. Through the system dynamics model, combined with the perspective of consumers and battery operators, the economic indicators of the battery rental mode are deduced and simulated, and the sensitivity analysis is realized, which can provide a reference for the economic analysis of the battery rental mode.
