The invention relates to the technical field of vehicle battery replacement, and discloses a battery charging and replacing station. The battery charging and replacing station comprises a battery replacing box body and a battery transfer device, a battery replacing chamber, a charging chamber and a power supply chamber which are communicated are formed in the battery replacing box body, the battery replacing chamber and the power supply chamber are located on the two sides of the charging cavity respectively, a power supply cabinet is arranged in the power supply cavity, and the power supply cabinet can supply power to a charging assembly in the charging cavity; the battery replacing chamber is used for entering and exiting of a vehicle with a to-be-replaced power battery, and the charging assembly is used for charging the power battery stored in the charging chamber; and the battery transfer device is configured to transfer between the battery replacing chamber and the charging chamber so as to transfer the power-shortage power battery on the vehicle into the charging chamber for charging, and the battery transfer device is further configured to transfer the fully-charged power battery in the charging chamber into the battery replacing chamber and install the battery replacing chamber on the vehicle. The battery charging and replacing station is small in occupied area, easy to put, capable of saving the working procedures of checking and debugging after putting, and convenient to operate.
