The invention relates to the technical field of battery swapping for electric vehicles. A control method of a smart battery swapping station includes: acquiring vehicle information of a vehicle requiring battery swapping, and retrieving a model type of a corresponding battery pack locking and unlocking hole and specific parameters from a database; when the vehicle arrives at a battery swapping operation platform, capturing an image of a vehicle chassis to determine an initial pose of the vehicle chassis; processing the initial pose to extract center coordinates of the locking and unlocking hole and a normal vector direction of the locking and unlocking hole; comparing the center coordinates of the locking and unlocking hole and the normal vector direction of the locking and unlocking hole with the retrieved model type of battery pack locking and unlocking hole and specific parameters in the database to determine if the information is consistent.

The present invention discloses a method and apparatus for photovoltaic DC direct-fed power generation based on controllable power supply. According to the present invention, the photovoltaic cells are directly connected to the DC microgrid, and the DC bus voltage is flexibly regulated by the controllable power supply in the DC microgrid to enable the photovoltaic cells to operate at the maximum power, thus eliminating the need for a DC interface converter when the photovoltaic cells are connected to the DC bus and reducing the cost and size of the distributed PV power generation system.
