The battery box used in the battery unit is the same structure as the battery box used in the vehicle to be replaced battery 16, and the two battery boxes can be used interchangeably, and are electrically connected to the uninterruptible power supply of the station. The uninterruptible power supply outputs electrical energy for supplying power to the battery replacing robot. When the battery unit power is lower than 20 %, the power supply is cut off and the uninterruptible power supply is used to supply power, such that the battery box with deficient power is carried to the transfer vehicle, while the battery box with the fully charged battery is carried to the battery support, so as to restore the battery power supply.

Example 2:

Based on the same concept of invention, the present invention further provides a method for replacing batteries, including:

S1. The vehicle to be replaced battery 16 and the battery transferring vehicle 15 are parked at the vehicle replacing battery platform 3 and the battery replacing power platform 4 respectively;

S2. The battery replacing robot moves along the length of the battery replacing box 2, the position of the power-deficient battery on the vehicle to be replaced battery 16 is located by the position detection device of the battery replacing robot. The mechanical arm main body 12 on the battery replacing robot extends from the vehicle end opening on the battery replacing box 2 and picks the battery-deficient battery on the battery replacing box 2. After that, the mechanical arm main body 12 retracts from the vehicle end opening. The battery replacing robot moves along the length of the battery replacing box 2, the vacant position of the battery position on the battery transferring vehicle 15 is located. The mechanical arm main body 12 on the battery replacing robot extends from the battery end opening on the battery replacing box 2 and théd/504728 stores the power-deficient battery into the vacant position of the battery position on the battery transferring vehicle.

S3. The battery replacing robot moves along the length of the battery replacing box 2, the position of the fully charged battery on the battery transferring vehicle 15 is located by the position detection device of the battery replacing robot. The mechanical arm main body 12 on the battery replacing robot extends from the battery end opening on the battery replacing box 2 and picks the fully charged battery on the transfer vehicle. After that, the mechanical arm main body 12 retracts from the battery end opening and then stores the battery on the vehicle to be replaced battery.

S4. The steps S2 and S3 are performed repeatedly until the fully charged batteries on the battery transferring vehicle 15 are replaced. After that, the battery transferring vehicle 15 departs from the battery replacing station 1 to the charging station 14 for charging the power-deficient batteries on the battery transferring vehicle 15. At the same time, the battery transferring vehicle 15 with fully charged batteries at the charging station 14 is parked at the battery replacing power platform 4 of the battery replacing station 1, such that a cycle is formed.

The above described are merely the preferred examples of the present invention, not used for limiting the present invention. Any modifications, equivalent replacements, improvements and the like made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
