Abstract:Charging pile as a way of slow charge, can effectively protect the battery and prolong battery life. In this paper, we investigate electric vehicle charging pile. After analyzing the pros and cons of the three construction and operation modes, namely, government predominance mode, power enterprise predominance mode and automobile manufacturers predominance mode, combined with China's actual situation, this paper intends to introduce a new business mode of power enterprise and automobile manufacturers alliance to construct charging pile.This paper establishes a charging pile profit function model with the consideration of government subsidy, construction costs, operating costs, and presents the basic idea of charging pile construction, for electric vehicle charging piles in China's long-term development to provide ideas and theoretical basis.
