Research on competition and investment strategy of electric vehicle charging and replacement mode

Based on consumers' different value preferences for EV charging and swapping battery, a tripartite game model is constructed from the perspective of EV manufacturers and swapping battery station builders to reveal the optimal decision under the competition between charging mode and swapping battery mode.By comparing the profit level and the number of swapping battery stations before and after the joining of swapping battery station builders, this paper explores the influence of swapping battery station hypothesis outsourcing on swapping battery vehicle manufacturers.The study found that although the construction of outlay swapping battery station can not increase the profits of swapping battery vehicle manufacturers, it can reduce the profits of charging vehicle manufacturers.When outsourcing, it is necessary to fully consider the appropriate dividend ratio to ensure the profit level of the swapping battery vehicle manufacturer.
