the control heavy truck 400 sends a fourth vehicle identification code of the heavy truck 400 to the power exchange station 100 through a wireless network;
when the third vehicle identification code and the fourth vehicle identification code are identical, the control power exchange station 100 transmits the third vehicle identification code or the fourth vehicle identification code to the cloud server 200, and the third vehicle identification code or the fourth vehicle identification code is used as the first vehicle identification code.
In this way, it can be determined that the heavy truck 400 entering the power exchange station 100 is the same vehicle as the heavy truck 400 transmitting the fourth vehicle identification code.
In particular, the phase may be a vehicle identification phase. After the heavy truck 400 enters the station, the station end EMS scans the tag 44 on the heavy truck 400 through the reading device 22, and obtains tag information in the tag 44 of the heavy truck 400, where the tag information includes a Vehicle Identification Number (VIN) of the heavy truck 400, and the vehicle identification number of the tag information is used as a third vehicle identification number. Meanwhile, the vehicle end controller 42 of the heavy truck 400 is connected to the station end EMS through the router 24, the vehicle end controller 42 actively reports the VIN of the vehicle to the station end EMS through the wireless network, the reported VIN is used as a fourth vehicle identification code, and the station end EMS compares the third vehicle identification code in the tag 44 with the fourth vehicle identification code reported by the vehicle controller. The vehicle end control system mainly comprises a vehicle end controller 42 and a tag 44.
When the third vehicle identification code is consistent with the fourth vehicle identification code, the station EMS uses the vehicle identification code to perform vehicle identification, and sends the third vehicle identification code or the fourth vehicle identification code to the cloud server 200, where the third vehicle identification code or the fourth vehicle identification code is used as the first vehicle identification code. When the third vehicle identification code and the fourth vehicle identification code do not coincide, the station EMS continues to search for other vehicles connected to the router 24 until the heavy card 400 that coincides with the third vehicle identification code in the tag 44 is found.
Alternatively, the reading device 22 may include an RFID (Radio Frequency Identification ) identifier. The tag 44 on the heavy card 400 is an RFID tag 44.
In certain embodiments, step 103 comprises:
in response to the user's access operation to the vehicle in-place portal, the control terminal device 300 sends an in-place signal and user information to the cloud server 200, where the user information includes a second vehicle identification code.
In this way, the in-place signal may be triggered by the user and sent to the cloud server 200.
Specifically, the vehicle in-place confirmation stage is that after a driver stops the vehicle, the vehicle in-place entrance can be accessed by using the power exchange APP to scan the two-dimensional code of the power exchange station 100 and clicking a vehicle in-place button of a graphical user interface. In response to the user accessing the vehicle in-place portal, the terminal device 300 may acquire the user information and generate an in-place signal, and send the user information and the in-place signal to the cloud server 200, where the user information includes a vehicle identification code bound to the user account, and the bound vehicle identification code is used as the second vehicle identification code.
After receiving the in-place signal sent by the terminal device 300, the cloud server 200 obtains user information (including the bound vehicle identification code, the user arrearage condition and other information), and the cloud server 200 compares the first vehicle identification code reported by the station end EMS with the bound second vehicle identification code. When the first vehicle identification code is consistent with the second vehicle identification code, the cloud server 200 issues an in-place signal to the station EMS. The vehicle information bound by the verification battery replacement APP is adopted in the embodiment, so that the function of vehicle battery replacement verification of the cloud server 200 is realized.
In some embodiments, the power conversion method includes:
when the first vehicle identification code and the second vehicle identification code are inconsistent, controlling the cloud server 200 to send vehicle incorrect information to the terminal device 300;
based on the incorrect information of the vehicle, the control terminal device 300 prompts the user to re-bind.
In this way, the user may be prompted to rebind the correct vehicle.
Specifically, when the first vehicle identification code and the second vehicle identification code are inconsistent, the cloud server 200 feeds back to the terminal device 300 that the binding vehicle is incorrect, and prompts the driver to re-bind. The prompting modes include, but are not limited to, modes of displaying patterns, characters, voice broadcasting, information pushing and the like on a graphical user interface of the power exchange APP.
In certain embodiments, step 107 comprises:
judging whether the power exchange station 100 meets the power exchange condition according to the in-place signal;
if the power change condition is met, the power change station 100 is controlled to send the met power change flag bit, the selected battery bank position number and the power battery code to the cloud server 200;

according to the power-on starting flag bit, the control terminal equipment 300 feeds back a power-on starting prompt;
in response to the access operation of the user to the power conversion starting inlet, the control terminal device 300 sends a power conversion starting flag bit to the cloud server 200;
the control cloud server 200 sends an open power change flag bit to the power change station 100;
and according to the start power change flag bit, the power change station 100 is controlled to execute power change operation on the heavy card 400.
Thus, the normal power exchanging operation can be ensured.
Specifically, the phase may include a vehicle start power-up verification phase and a vehicle start power-up phase.
