Specifically, referring to fig. 1 and fig. 2, in the running process of the rail vehicle 200, the train control and management system 220 sends vehicle information of the vehicle to the swap management platform 100. The vehicle information at least includes current position information and current power information of the rail vehicle 200. The vehicle information is used for the power swapping management platform 100 to determine whether the rail vehicle 200 has a power swapping requirement. It should be noted that, in the embodiment of the present application, the communication between the train control and management system 220 and the power swapping management platform 100 is implemented by the vehicle-mounted controller 210, for example, the train control and management system 220 sends vehicle information of a vehicle to the vehicle-mounted controller 210, and the vehicle-mounted controller 210 sends the vehicle information to the power swapping management platform 100 in a wireless communication manner. The onboard controller 210 is not shown in fig. 2 to simplify the interaction flow diagram.
When receiving the vehicle information sent by the rail vehicle 200, the power swapping management platform 100 determines whether the rail vehicle 200 has a power swapping requirement according to the vehicle information of the rail vehicle 200.

It should be noted that the railway vehicle 200 may include a plurality of cars 201, and each car 201 is configured with a battery management system 230. It can be understood that the information interaction process between the battery management system 230 of each car 201 and the power swapping station 300 is the same. For convenience of description, in the embodiment of the present application, a detailed description is given of an information interaction process between the battery management system 230 of the car 201 and the power swapping station 300 by taking a car 201 as an example.
After receiving the power swapping indication signal, the battery management system 230 sends a power swapping application signal to the power swapping station 300.

Illustratively, when the swapping station 300 does not receive the handshake success signal within a preset time period after sending the handshake signal, it feeds back a handshake overtime or handshake failure signal to the staff. In this embodiment, after receiving the power swapping indication signal, the battery management system 230 periodically sends the power swapping application signal until receiving the agreement application signal. In the embodiment of the present application, the battery management system 230 further feeds back the consent application signal to the train control and management system 220.
After receiving the battery pack information fed back by the carriage 201, the battery swapping station 300 formulates a corresponding battery swapping scheme for the carriage 201, and starts to execute a battery swapping operation on the carriage 201. In this embodiment, the battery swapping station 300 is further configured to feed back, to the battery management system 230, information of a new battery pack to be replaced at this time and send information of a battery pack replacement progress of the car 201 in real time. In some embodiments, the battery management system 230 is further configured to forward the battery replacement schedule information of the current car 201 to the train control and management system 220.

In this embodiment, the battery management system 230 is further configured to forward the new battery pack information of the current car 201 to the train control and management system 220 when it is determined that the battery pack replacement of the current car 201 is completed. For example, the battery management system 230 determines whether the battery pack replacement of the vehicle 201 is completed by checking the connection state of a new battery pack of the vehicle.
The battery replacement station 300 responds to the battery pack replacement completion signal, checks whether the battery replacement device 320 corresponding to the carriage 201 returns to the home position, and sends a battery replacement end signal to the battery management system 230 of the carriage 201 when determining whether the battery replacement device 320 corresponding to the carriage 201 returns to the home position.
After receiving the power swapping end signal, the battery management system 230 forwards the power swapping end signal to the train control and management system 220, and controls the high-voltage electrification of the local carriage 201.

Referring to fig. 4, an embodiment of the present application provides another method for controlling automatic power switching of a rail vehicle, where the method is applied to a rail vehicle 200, and specifically, the method includes the following steps:
In this embodiment, the battery management system 230 of each car of the rail vehicle 200 performs battery swapping information interaction of the battery pack of the corresponding car with the target battery swapping station 300 through the corresponding first wireless signal conversion module 240 in a wireless communication manner.
Referring to fig. 5, fig. 5 is a flowchart illustrating steps of another method for controlling automatic power switching of a rail vehicle according to an embodiment of the present application. Compared with the embodiment shown in fig. 4, in this embodiment, step 703 specifically includes steps 7031 to 7033, and step 705 specifically includes steps 7051 to 7052. In this embodiment, the method further includes steps 7041-7043. As shown in fig. 5, the method for controlling automatic power switching of a rail vehicle provided in this embodiment specifically includes the following steps:
In this embodiment, the target location is a target battery swapping location planned for the rail vehicle 200 by the battery swapping management platform 100, that is, a location of a battery swapping area. For example, after the rail vehicle 200 is parked at the target power swapping location, the positions of the cars 201 of the rail vehicle 200 correspond to the positions of the power swapping devices 320 in the target power swapping station 300 one by one. It can be understood that after the traction of the whole vehicle is blocked, the rail vehicle 200 is parked in the power exchange area until the power exchange is finished and then the contact blocking is carried out.
In this embodiment, the swap indication signal is used to trigger the battery management system 230 of each car 201 to perform swap information interaction with the target swap station 300. After receiving the power swapping indication signal, the battery management systems 230 of the cars 201 respectively initiate a process of exchanging power information interaction with the target power swapping station 300.
In this embodiment of the application, the swap application signal is used to trigger the swap server 310 to configure the swap device 320 for each car 201 and return a handshake signal of the corresponding swap device 320. Specifically, after receiving the corresponding power swapping application signal sent by each battery management system 230, the power swapping server 310 forwards the power swapping request signal to the corresponding power swapping device 320, so as to trigger each power swapping device 320 to send a corresponding handshake signal.
To describe the handshaking procedure between the battery management system 230 and the corresponding battery swapping device 320 in more detail, the present embodiment further provides the following examples: the battery management system n of the carriage n corresponds to the battery swapping device n, the battery management system n sends the battery swapping application signal to the battery swapping server 310, and the battery swapping server 310 forwards the battery swapping application signal to the battery swapping device n. The battery swapping device n responds to the battery swapping application signal and sends a handshake signal to the battery swapping server 310, the battery swapping server 310 sends the handshake signal to the battery management system n, and the battery swapping device n receives the handshake success signal fed back by the battery management system n through the battery swapping server 310, so that the successful configuration between the carriage n and the battery swapping device n is realized.
In step 7042, the positive and negative contactors of the battery pack of the vehicle 201 are disconnected by the battery management system 230 of each vehicle 201. In some embodiments, before the positive and negative contactors of the battery pack of the vehicle 201 are disconnected, the battery management system 230 of each vehicle 201 further sends a discharge prohibition signal to the high-voltage and low-voltage loads in the corresponding vehicle 201 to perform a safety prompt. It can be understood that after the positive and negative contactors of the battery pack are disconnected, the driving motor and the high and low voltage loads in the carriage 201 are both disconnected, so that a short-circuit fault is avoided in the battery replacement process. In this embodiment, after the positive and negative contactors of the battery pack are disconnected, the battery management system 230 and the first wireless signal conversion module 240 of the car 201 are separately powered by a communication power supply (not shown), so as to ensure that the battery management system 230 of the car 201 and the battery swap server 310 can communicate normally in the battery swap process.
Specifically, the battery management system 230 of each car 201 sends the battery pack information of the corresponding car 201 to the target power swapping station 300, so that the target power swapping station 300 formulates a corresponding power swapping scheme for each car 201 according to the battery pack information of each car 201. Illustratively, the battery pack information includes at least one of current battery pack type information, swap-allowed voltage information, swap-allowed power information, SOC information (State of Charge), and voltage information of the battery pack unit of each car 201. In other embodiments, the battery pack information may also include other information.
Specifically, the battery management system 230 of each car 201 receives new battery pack information configured for the corresponding car 201 and battery pack replacement progress information fed back by the target power conversion station 300. Illustratively, the new battery pack information includes at least one of new battery pack type information, rated voltage information, rated power information, and SOC information of the present replacement. In other embodiments, the new battery pack information may also include other information.
