The vehicle battery replacement platform comprises at least two battery boxes and other support structures, and different battery boxes are connected together in a series or parallel mode. The voltage requirement of the vehicle battery replacement platform is met by the battery boxes which are connected in series and in parallel, for example, the voltage of a single battery box is 153V, the voltage requirement of the vehicle battery replacement platform is 480V-700V, and the voltage requirement of the battery boxes is met by the battery boxes in series and in parallel.
The candidate battery boxes are all battery boxes in operation in the vehicle battery replacement platform, the operation states of the candidate battery boxes are whether the battery boxes normally operate or not, and the target battery box is determined from the candidate battery boxes according to the operation states, and the target battery box can be a battery box in an appointed operation state in the candidate battery boxes, which is not limited in this embodiment.

Example two
Fig. 2 is a flowchart of a battery pack connection method according to a second embodiment of the present invention, and this technical solution is supplementary explained with respect to a process of determining an adjacent battery pack having a connection relationship with the target battery pack according to the battery pack connection manner.

and adjusting the connection relation between the target battery pack and the adjacent serial battery packs to be the connection relation between the adjacent serial battery packs. Specifically, the flow chart of the battery pack connection method is shown in fig. 2:
And determining the adjacent series battery packs having the series connection relation with the target battery pack according to the connection mode of the battery packs. And determining adjacent series-connected battery packs according to the positions of the target battery packs, for example, the target battery pack B is connected with the battery pack A and the battery pack C in series, and the target battery pack B is positioned between the battery pack A and the battery pack C, so that the battery pack A and the battery pack C are adjacent series-connected battery packs of the target battery pack B.
And 230, adjusting the connection relation between the target battery pack and the adjacent serial battery packs to be the connection relation between the adjacent serial battery packs, so as to determine the driving mode of the vehicle according to the adjusted connection relation.

And determining whether an adjacent parallel battery pack in parallel connection relation with the target battery pack exists according to the connection mode of the battery packs. And determining adjacent parallel battery packs according to the positions of the target battery packs, for example, if the target battery pack B is connected with the battery pack D in parallel, the battery pack D is the adjacent parallel battery pack of the target battery pack B. The conditions of the series-connected battery packs of the adjacent parallel-connected battery pack and the target battery pack are generally consistent, so that the adjustment manner of the connection relationship between the target battery pack and the adjacent series-connected battery pack can be applied to the adjustment of the connection relationship between the adjacent parallel-connected battery packs in series relationship with the adjacent parallel-connected battery packs.
For example, the connection relationship of the target battery pack B is adjusted by disconnecting the connection between the target battery pack B and the adjacent series battery pack, and connecting the adjacent series battery pack a and the adjacent series battery pack C in series, and the connection relationship of the adjacent parallel battery pack D is also adjusted by disconnecting the connection between the adjacent parallel battery pack D and the adjacent parallel series battery pack, and connecting the adjacent parallel series battery pack E and the adjacent parallel series battery pack F in series.

And if the current platform voltage is greater than or equal to the preset voltage, determining that the driving mode of the vehicle is a limp driving mode or a power reduction driving mode. And correspondingly adjusting the running mode of the battery replacement platform according to the determined running mode, for example, when the running mode is a limp running mode, limiting the discharge current so as to meet the limp running.
And determining a proper driving mode according to the voltage of the vehicle battery replacement platform after the connection relation is adjusted, so that the condition that the vehicle cannot drive due to voltage drop is avoided, and the driving efficiency of the vehicle is improved.
