The paper analyzes the living space of the battery leasing company in the business model “vehicle and battery separated, battery leasing”, and its effected factors such as the battery price, the battery life cycle, the gasoline price, as well as battery type and vehicle type. The results have shown that leasing battery cannot get profit under the current battery price, life-cycle, gasoline price, and the financial subsidies. However, with the decrease of the battery price and the increase of battery cycle life and the gasoline price, the battery leasing company is possible to get the living space. Micro EVs give the battery leasing company an upper bound 10 percent higher than that of the compact EVs in the same situation. To make the living space of the battery leasing company just exist, the financial subsidies should be at least 5000 RMB/kw.h. The application of lead-acid battery will help the battery leasing company gain the living space. The lower bound corresponding to the lead-acid battery is only 23 percent of that corresponding to the li-ion battery.
