s101: and confirming that the authorization authentication of the vehicle needing to be replaced and connected is successful.
The mobile battery-replacing vehicle is in wireless connection with the battery-replacing vehicle, and can be connected in a wireless mode such as WIFI (wireless fidelity) as an example. After the distance between the vehicle needing to be switched and the mobile battery switching vehicle is smaller than the connectable distance, the vehicle needing to be switched and the mobile battery switching vehicle are automatically connected. After the mobile battery replacement vehicle is connected with the vehicle needing battery replacement, whether the vehicle needing battery replacement is an authorized vehicle capable of replacing battery is determined, and after the vehicle authentication is successful, the vehicle needing battery replacement can continue to perform subsequent battery replacement operation.
S102: and after confirming that the vehicle needing to be powered is the first trolley needing to be powered, acquiring the state information of the vehicle needing to be powered.
A plurality of vehicles needing to be replaced may exist in the same time period, namely the mobile replacing vehicle can be connected with the plurality of vehicles needing to be replaced at the same time. However, when the battery replacement is performed, only the vehicles needing to be replaced can be replaced one by one, and therefore, the mobile battery replacement vehicle acquires the state information of the first trolley after confirming that one vehicle needing to be replaced is the first trolley needing to be replaced among the plurality of vehicles needing to be replaced in the queue. Optionally, the state information includes at least one of a handbrake state, a car door state, a steering wheel angle, and a battery voltage state.
S103: and after the state information is determined to meet the set conditions, generating a battery unlocking instruction to unlock the battery rack of the vehicle needing to be replaced.
Illustratively, when the state information includes the hand brake state, the vehicle door state, the steering wheel angle and the battery voltage state at the same time, the set conditions are hand brake locking, vehicle door closing, steering wheel angle of zero and battery power-down. After the state information is determined to meet the set conditions, the mobile battery replacement vehicle generates a battery unlocking instruction and sends the battery unlocking instruction to the vehicle needing battery replacement so as to unlock the battery rack which is provided with the battery box with insufficient electric quantity and is arranged on the vehicle needing battery replacement, and therefore the battery box with insufficient electric quantity can be taken out in the following process. In addition, if it is determined that the state information does not satisfy the set condition, the mobile battery replacement vehicle may generate a state adjustment command to cause the battery replacement vehicle to readjust its own state. Exemplarily, the state adjustment instruction can be in a voice broadcast mode, and the mobile battery replacement vehicle broadcasts the 'state of the vehicle adjustment' in the voice broadcast mode so as to remind a driver (user) of the vehicle needing to be replaced that the vehicle door is not closed or the hand brake is not locked, and the like, so that the driver of the vehicle needing to be replaced can adjust the vehicle after receiving the broadcast information.
S104: and after the battery frame is successfully unlocked, transporting the battery box on the mobile battery transport vehicle to the vehicle needing replacing the battery box so as to replace the original battery box on the vehicle needing replacing the battery.
After the mobile battery replacement vehicle confirms that the battery rack is successfully unlocked, the battery disassembly module such as a mobile robot can be controlled to take out the battery box with insufficient power on the vehicle needing battery replacement and take out the battery box with sufficient power on the mobile battery transport vehicle to transport the battery box to the vehicle needing battery replacement for installation, and then the battery replacement process of the vehicle needing battery replacement is completed.

s111: and confirming that the authorization authentication of the vehicle needing to be replaced and connected is successful.
Specifically, basic information of the electric vehicle needing to be replaced and connected is obtained.
Illustratively, the basic information at least comprises an identification code and a battery code of the electric vehicle to be replaced. After the mobile power change vehicle is connected with the vehicle needing power change, the vehicle needing power change sends basic information generated by the vehicle needing power change to the mobile power change vehicle.
And sending the basic information to the cloud platform so that the cloud platform can carry out authorization and authentication on the electric vehicle needing to be replaced.
The cloud platform stores the identification codes of all vehicles which are allowed to be powered by the mobile power switching system into a storage library of the cloud platform in advance. After the cloud platform receives the basic information of the vehicle needing to be replaced, which is sent by the mobile replacing vehicle, the received identification code of the vehicle is compared with the identification code in the storage library, and whether the vehicle needing to be replaced is authorized and authenticated successfully is judged. And if the consistent identification codes are found in the repository, generating information with consistent authentication, and sending the information to the mobile power change car. And (the mobile battery replacement vehicle) if receiving the information of consistent authentication, confirming that the authorization authentication of the battery replacement vehicle is successful. And if the cloud platform does not find the consistent identification code in the storage library, generating information with inconsistent authentication and sending the information to the mobile power change car. And the mobile battery replacement vehicle receives the information of inconsistent authentication, determines that the vehicle authentication fails, and reports 'drive-away request' in a voice broadcasting mode to remind a corresponding user to drive the vehicle away from the mobile battery replacement system. Meanwhile, the cloud platform is also connected with mobile equipment of the user, such as a mobile phone, and if the cloud platform generates authentication inconsistent information, information of authentication failure is sent to a specific APP of the mobile phone of the user to remind the user.
