摘要： 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.
