For example, the main components and functions of the vehicle battery swap method architecture may include:

The Vehicle Control Unit (VCU) is responsible for interpreting and analyzing the input signals. Analyze and determine whether the current conditions for entering the power swap are met and whether the conditions for exiting the power swap are met, sending corresponding display instructions to the instrument controller, sending instructions for shielding and storing fault codes to the controller, and sending high-voltage power-on or high-voltage power-off to the controller. instructions, etc.;

Figure 5 is a concrete representation of Figure 4, and is also the main part of the power exchange control of this method. The control process may include:

1. Vehicle preparation. Drive the electric vehicle into the designated station of the battery swapping station and keep it powered on at high voltage or low voltage. At this time, the battery replacement indicator light on the instrument is off.

2. Determination of power exchange entry conditions. Depress the brake pedal, press and hold the EPB unlock switch, and then press the key door ignition switch. When the vehicle does not have the following faults (faults affecting high-voltage power on or off, braking system faults, BMS faults, BCM faults, etc.), the battery replacement process is activated.

3. VCU controls the high voltage under the vehicle. Complete high-voltage power-off within the specified time (can be calibrated, usually a few seconds) and enter the next step. If the high-voltage power-off is not completed within the specified time, the battery replacement process will be exited and the fault code will be stored.

4. After the high-voltage power-off is completed, the controller sends a power swap enable signal. Shield the communication failure of the BMS controller and control the battery replacement indicator light to flash to remind the vehicle that it is ready and the battery replacement can start normally.

5. Replace the battery. The battery swapping station removes the battery from the electric vehicle and replaces it with another battery.

6. After the battery replacement is successfully completed, the battery replacement indicator light will turn to a steady state and remain on for a period of time (the time can be calibrated). At this point, it means that the battery replacement has been completed.

7. Perform the "one-button start" operation, that is, depress the brake pedal and press the key door ignition switch. The VCU stops sending the battery replacement enable signal, cancels the battery replacement process, releases the fault code shielding, and controls the high voltage on the entire vehicle. Change The power indicator light goes out and the battery replacement is completed.

Currently, with the popularization of electric vehicles in the online ride-hailing and taxi markets, battery swapping technology with the purpose of extending daily driving range has attracted increasing attention. At present, electric vehicle brands, high-voltage power battery brands and battery swap station suppliers are mixed, and relevant industry laws and regulations are under construction. This leaves a large design space for the compatibility and interactivity of electric vehicles and battery swap stations. For some power-swapping stations or electric vehicles that are not highly intelligent, their software and hardware facilities may not be complete. In addition, due to different brands, signal interaction between the two may not be possible.

The technical solution of the embodiment of this application introduces a vehicle power swapping method system and method, which is intended to improve the compatibility and versatility of battery swapping for electric vehicles. Considering that in order to control costs, some online ride-hailing services may not have a central entertainment host operating screen. In view of this, in this method, the battery replacement process can be triggered by simply operating a common mechanical device. Considering that some battery swap stations may still be in semi-automatic battery swap mode, that is, there is no signal interaction between the battery swap station and the electric vehicle. In view of this, in this method, the startup and exit of the battery swap process of the electric vehicle do not need to rely on signals from the battery swap station at all. Power exchange enable signal. This application can be applied to pure electric battery-swapping models.
