Abstract: A method and a system for controlling battery swapping of a vehicle and a vehicle are provided. The method includes: receiving, by a vehicle control unit (VCU), a battery swapping instruction, and transmitting the battery swapping instruction to a battery manager when the vehicle is in a high-voltage power-on state; transmitting, by the battery manager, an enable instruction to a direct current (DC) charger assembly in response to the received battery swapping instruction; and performing, by the DC charger assembly, a starting operation in response to the enable instruction, so as to provide a power supply voltage to a vehicle load after an electrical connection between a power battery pack and a high-voltage circuit of the vehicle is cut off during battery swapping of the vehicle.

Abstract: A method for controlling battery swapping of a vehicle is provided. The vehicle induces a vehicle control unit (VCU), a bidirectional DC-DC converter assembly, a vehicle load, a battery controller, a power battery pack, and a storage battery. The method includes: receiving, by the VCU, a battery swapping instruction when the vehicle is in the high-voltage power-on state; transmitting, by the VCU, a switching instruction to the bidirectional DC-DC converter assembly in response to the battery swapping instruction; and disabling, by the bidirectional DC-DC converter assembly, the buck mode in response to the switching instruction to cut off electrical connection between the power battery pack and a high-voltage circuit of the vehicle by a battery controller, and enabling the boost mode in response to the switching instruction to supply power to the vehicle load by the storage battery through the bidirectional DC-DC converter assembly.

Abstract: A method for controlling automatic battery swapping of a rail vehicle, includes: receiving vehicle information sent by the rail vehicle; determining whether the rail vehicle has a battery swapping need based on the vehicle information of the rail vehicle; in response to determining that the rail vehicle has the battery swapping need, determining a target battery swapping station according to the battery swapping need; and sending a battery swapping notification signal and a vehicle control signal to the rail vehicle, and sending a battery swapping request signal to the target battery swapping station, where the battery swapping notification signal includes position information of the target battery swapping station, the vehicle control signal controls the rail vehicle to travel to the target battery swapping station, and the battery swapping request signal includes identification information of the rail vehicle and requests the target battery swapping station to swap a battery pack for the rail vehicle.

Abstract: A railway vehicle charging control method includes the following steps: receiving vehicle information of the railway vehicle and a charging request transmitted by a signal system; establishing wireless communication connection with a vehicle control unit of the railway vehicle according to the vehicle information of the railway vehicle; determining a pantograph charger corresponding to the railway vehicle; controlling the pantograph charger corresponding to the railway vehicle to descend; and controlling, according to the charging request, to start charging the railway vehicle. The method is combined with the signal system of the railway vehicle, establishes communication connection with the corresponding railway vehicle according to the charging request and the vehicle information of the railway vehicle transmitted by the signal system, and controls the pantograph charger corresponding to the railway vehicle to descend, to charge the railway vehicle.
