In a specific embodiment of the invention, when a power exchange preparation signal that a power exchange vehicle drives into a target power exchange platform for power exchange is received, a control device of a power exchange station determines that a power exchange vehicle needs to exchange power on the target power exchange platform, obtains the number of charging chambers spliced by the target power exchange platform at this time, and determines that a better power exchange strategy is selected as a target power exchange strategy from at least one power exchange strategy according to the difference in the number of the charging chambers, that is, an optimal power exchange strategy can be switched according to different power exchange scenes, and further, power exchange equipment in the charging chambers is controlled to exchange power for the power exchange vehicle according to the target power exchange strategy, which is beneficial to shortening of power exchange time and improvement of power exchange efficiency. Meanwhile, due to the diversification of the battery replacement strategy, the corresponding relation between the battery replacement platform and the battery replacement room can be diversified, namely, the number of the battery replacement platforms relative to the number of the battery replacement rooms can be reduced by the mode that the same battery replacement room serves a plurality of battery replacement platforms, the cost is reduced by improving the land utilization rate, and meanwhile, the battery replacement efficiency is improved by the mode that one battery replacement platform serves a plurality of battery replacement rooms.
