[0042] In this embodiment, as the number of battery swapping vehicles increases, the number of battery swapping stations also increases. For battery swapping stations with low battery swapping frequency, the power demand is small, and long-term connection to the municipal power grid and transformer will cause a large amount of power waste. This embodiment provides a method for controlling a battery swapping station, such as Figure 1 As shown, the control method of the battery swap station includes steps S10 to S40, and each step is described in detail as follows:

[0043] In step S10, based on the start of the battery swap station, the expected battery swap frequency of the battery swap station can be obtained. Among them, the expected battery swap frequency includes the expected number of battery swaps within the expected time of the battery swap component 11. By obtaining the expected battery swap frequency of the battery swap station, the subsequent battery swap demand of the battery swap station is judged to facilitate determination of whether the battery swap station needs to switch to a low-frequency working state. The expected battery swap frequency of the battery swap station can be obtained by obtaining the number of battery swaps at the battery swap station within a period of time or inputting the expected battery swap information in advance.

[0044] In step S20, based on the fact that the expected power exchange frequency of the power exchange component 11 is less than the set number of times, the power exchange station can switch to a low-frequency working state. Among them, the low-frequency working state may include the first energy supply unit 121 switching to a power-off state, and the second energy supply unit 122 supplying power to the control component 13. The first energy supply unit 121 may include a municipal power grid and a transformer. The power-off state may include turning off the transformer, and the municipal power grid is electrically disconnected from the transformer. The second energy supply unit 122 may include a battery box 1221 of the power exchange station. By turning off the transformer and disconnecting the electrical connection between the municipal power grid and the transformer, and using the battery box 1221 to power the control component 13, the energy waste of the power exchange station is reduced, thereby reducing the operating cost of the power exchange station.

[0045] In step S30, based on the battery swap station switching to a low-frequency operating state and the battery swap vehicle moving to the battery swap station, the second energy supply unit 122 can supply power to the battery swap component 11, and the battery swap component 11 can swap power for the battery swap vehicle.

[0046] In step S40, based on the completion of the battery swapping of the battery swapping vehicle, the battery swapping station can switch to the monitoring state. Among them, the monitoring state may include the battery swapping component 11 being electrically disconnected from the second energy supply unit 122. When the battery swapping of the battery swapping vehicle is completed, the battery swapping station needs to maintain the monitoring state, and ensure that the battery swapping station can achieve real-time control of the battery swapping station through the control component 13 to ensure that the battery swapping station can operate normally.

[0047] In this embodiment, step S20 includes step S211 to step S212, and each step is described in detail as follows:

[0048] In step S211, based on the fact that the battery swapping frequency estimated by the battery swapping station is less than the set number of times, the power status of the battery box 1221 can be obtained.

[0049] In step S212, based on the number of battery boxes 1221 in high power state being greater than or equal to the first set number, the battery swap station can switch to a low-frequency working state. Among them, the battery boxes 1221 in high power state may include battery boxes 1221 with a power greater than the first set power. When the number of battery boxes 1221 in high power state at the battery swap station is large, the battery swap station can reduce the waste of electric energy while meeting the battery swapping needs of battery swapping vehicles by switching to a low-frequency working state.

[0050] In this embodiment, step S20 may include step S221 to step S222, and each step is described in detail as follows:

[0051] In step S221, based on the number of battery boxes 1221 in a high-power state being less than the first set number, the battery swap station can switch to a high-frequency working state. The high-frequency working state may include turning on the transformer, and connecting the municipal power grid to the transformer. When the number of battery boxes 1221 in a high-power state is small, the battery boxes 1221 can be charged through the municipal power grid by switching to a high-frequency working state, ensuring that the battery boxes 1221 in the battery swap station can meet the battery swapping needs of the battery swapping vehicles.

[0052] In step S222, based on the battery swap station switching to a high-frequency working state and the number of high-power battery boxes 1221 being greater than or equal to the second set number, the battery swap station can be switched to a low-frequency working state. The second set number can be greater than the first set number. When the number of high-power battery boxes 1221 at the battery swap station is greater than or equal to the second set number, the high-power battery boxes 1221 can meet the battery swapping needs of the battery swapping vehicles. At this time, the battery swap station can be switched to a low-frequency working state to reduce the power loss of the battery swap station.

[0053] In this embodiment, step S20 may include step S231 to step S233, and each step is described in detail as follows:

[0054] In step S231, based on the estimated power exchange frequency of the power exchange component 11 being less than the set number, the working state of the green energy 1222 of the second energy supply unit 122 can be obtained. The second energy supply unit 122 also includes green energy 1222. Green energy 1222 can include solar energy, wind energy, and the like.

[0055] In step S232, based on the green energy 1222 being in the energy supply state, A and B are obtained, wherein A is the power supply of the green energy 1222, and B is the power consumption of the battery swap station.

[0056] In step S233, based on A≥B, the battery swap station switches to a low-frequency working state. The low-frequency working state includes the first energy supply unit 121 switching to a power-off state, the green energy 1222 supplies power to the battery swap component 11 and the control component 13, and the remaining power is used to charge the battery box 1221. When the green energy 1222 is in a power supply state and the power supply of the green energy 1222 is large, the green energy 1222 can be used to power the battery swap station, thereby reducing the power consumption of the battery box 1221. At the same time, the remaining power can be used to charge the battery box 1221 to achieve reasonable use of power.

[0057] In this embodiment, step S20 may further include step S234.

[0058] In step S234, based on A<B, the battery swap station can switch to a low-frequency working state. The low-frequency working state can include the first energy supply unit 121 switching to a power-off state, and the green energy 1222 and the battery box 1221 jointly power the control component 13. When the green energy 1222 has a small amount of power supply, the green energy 1222 and the battery box 1221 can jointly power the power supply to reduce the power demand of the battery box 1221, thereby reducing the power supply of the battery box 1221.

[0059] In this embodiment, step S30 may include step S31 to step S32, and each step is described in detail as follows:

[0060] In step S31, based on the switching of the battery swap station to the low-frequency working state, the working state of the green energy 1222 of the second energy supply unit 122 can be obtained. The second energy supply unit 122 can also include the green energy 1222.

[0061] In step S32, based on the green energy 1222 being in the energy supply state and the battery swapping vehicle moving to the battery swapping station, the green energy 1222 can be used together with the battery box 1221 to supply power to the battery swapping component 11, and the battery swapping component 11 can replace the battery for the battery swapping vehicle. When the battery swapping vehicle moves to the battery swapping station, the battery swapping component 11 starts to work. At this time, the battery swapping station has a large demand for battery swapping. When the green energy 1222 is in the energy supply state, the green energy 1222 and the battery box 1221 can be used together to supply power to reduce the power demand of the battery box 1221 at the battery swapping station, thereby reducing the power supply of the battery box 1221.

[0062] In this embodiment, the power of the battery box 1221 in the second energy supply unit 122 can be greater than the second set power. When the power of the battery box 1221 is low, continuing to use the battery box 1221 will cause damage to the battery box 1221 itself. Other battery boxes 1221 can be replaced to supply power to the battery swap station to prevent the battery box 1221 from being damaged by low power.

[0063] In this embodiment, step S20 may include step S241 to step S243, and each step is described in detail as follows:

[0064] Step S241, based on the fact that the battery swapping frequency of the battery swapping component 11 is expected to be greater than or equal to the set number of times, the battery swapping station can be switched to a high-frequency working state.

[0065] Step S242, based on the battery swap station switching to a high-frequency working state and the battery swap vehicle moving to the battery swap station, the first energy supply unit 121 can supply power to the battery swap component 11 and the control component 13, and the battery swap component 11 can replace the battery for the battery swap vehicle. When the expected battery swap frequency of the battery swap station is large, the battery swap station can switch to a high-frequency working state to ensure that the battery box 1221 of the battery swap station can be continuously charged to meet the battery swap demand of the battery swap vehicle.

[0066] Step S243, based on the battery swapping of the battery swapping vehicle being completed, the battery swapping station switches to a monitoring state, wherein the monitoring state includes the battery swapping component 11 being electrically disconnected from the first energy supply unit 121.

[0067] This embodiment discloses a battery swap station control system. The battery swap station control system can be applied to the battery swap station control method of any embodiment. The battery swap station control system may include:
