Reservation charging authentication method and system for electric vehicle and charging station

The invention discloses a reservation charging authentication method and system for an electric vehicle and a charging station, and the method comprises the following steps: S1, determining a selection strategy of an electric vehicle end for a charging station end, and releasing a charging reservation application to the charging station end according to the selection strategy; and S2, determining an authentication strategy of the charging station end to the electric vehicle end, and providing a charging service for the electric vehicle end according to the authentication strategy. According to the method, the selection conditions of the electric vehicle terminal for the charging station terminal are mathematically quantified, and the multi-target selection function for weighing the selection conditions is combined and constructed to obtain the time cost, the economic cost and the safety cost for weighing the charging user so as to ensure that all the selection conditions of the electric vehicle terminal for t
