[0070] Specifically, the vehicle controller 4 detects the vehicle status in real time. For example, the vehicle status can be a moving state or a stationary state, and converts the vehicle status into a vehicle status signal and transmits it to the routing communication module 2. At the same time, the battery management system 5 detects the battery status of each battery cell in the battery pack in real time. For example, the battery cell status includes battery cell power information, battery cell temperature information, etc., which is not limited in the embodiment of the utility model, and obtains the battery cell number of each battery cell, and converts the battery cell number of each battery cell and the battery cell status corresponding to the battery cell number into a battery status signal, and transmits the battery status signal to the routing communication unit 2. The routing communication unit 2 transmits the received vehicle status signal and battery status signal to the control unit 1.

After receiving the battery swap control signal, the wireless communication unit 3 transmits the battery swap control signal to the control unit 1. The control unit 1 sends an unlocking signal to the locking mechanism of the vehicle battery according to the battery swap control signal to control the locking mechanism of the vehicle battery to open.

The control unit 1 receives the vehicle status signal and the battery status signal, and transmits the vehicle status signal and the battery status signal to the wireless communication unit 3. The wireless communication unit 3 receives the vehicle status signal and the battery status signal, and transmits the vehicle status signal and the battery status signal to the battery replacement station 6. The battery replacement station 6 judges the vehicle status signal and the battery status signal. The wireless communication unit 3 will receive the battery replacement control signal sent by the battery replacement station 6, and send the battery replacement control signal to the control unit 1.

[0084] Specifically, after the control unit 1 controls the locking mechanism of the vehicle battery to open, the staff replaces the abnormal battery cells in the battery pack. After the replacement is completed, the locking mechanism of the vehicle battery is automatically locked. At this time, the battery management system 5 will detect the information that the locking mechanism of the vehicle battery is automatically locked, and convert the information that the locking mechanism is automatically locked into a battery replacement completion signal and transmit it to the routing communication unit 2. After receiving the battery replacement completion signal sent by the battery management system 5, the routing communication unit 2 sends the battery replacement completion signal to the control unit 1. After receiving the battery replacement completion signal, the control unit 1 transmits the locking success signal to the battery replacement station 6 through the wireless communication unit 3, thereby realizing the battery replacement feedback to the battery replacement station 6.

[0090] Among them, the fault signal includes at least one of a battery swap lock pin locking fault signal, a battery swap connector connection fault signal, a battery swap connector overtemperature fault signal and a communication timeout fault signal.

[0091] Specifically, when the vehicle controller 4 detects abnormalities in the battery replacement lock pin, battery replacement connector, etc., it converts the abnormal information of the battery replacement lock pin, battery replacement connector, etc. into a fault signal, and transmits the fault signal to the control unit 1 through the routing communication unit 2. After receiving the fault signal, the control unit 1 sends an alarm signal to the alarm unit 7, and then controls the alarm unit 7 to perform alarm processing, reminding the staff that abnormalities in the battery replacement lock pin, battery replacement connector, etc.
