The embodiments described below with reference to the accompanying drawings are optional and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0041] In the related art, the integrated power supply device of the vehicle is compatible with single-phase AC charging and three-phase AC charging functions. However, when the vehicle has a DC charging and discharging requirement, if the voltage provided by the charging source does not match the voltage required for DC charging and discharging, an additional DC / DC module is required to adjust the output voltage to the voltage level required for DC charging and discharging.

[0042] The present application embodiment provides an integrated power system 100 (such as Figure 1 to Figure 15 As shown), the integrated power supply system 100 of the embodiment of the present application does not need to additionally set up a DC / DC module to adjust the output voltage, which saves circuit resources to a large extent and reduces costs.

[0043] See also Figure 1 as well as Figure 2, the integrated power system 100 provided in the embodiment of the present application may include a first bidirectional conversion circuit 10 and a second bidirectional conversion circuit 20. The first bidirectional conversion circuit 10 may include a first terminal 11 and a second terminal 12, and the first bidirectional conversion circuit 10 may convert the AC voltage connected to the first terminal 11 into a DC voltage output by the second terminal 12, or convert the DC voltage connected to the second terminal 12 into an AC voltage output by the first terminal 11. The second bidirectional conversion circuit 20 may include a third terminal 21 and a fourth terminal 22, and the second bidirectional conversion circuit 20 is configured to convert the AC voltage connected to the third terminal 21 into a DC voltage output by the fourth terminal 22, or convert the DC voltage connected to the fourth terminal 22 into an AC voltage output by the third terminal 21. If the integrated power system 100 operates in the first mode, the second terminal 12 is connected to the DC charge and discharge port 300, the first terminal 11 is connected to the third terminal 21, and the fourth terminal 22 is connected to the battery 400, so that the voltage connected to the DC charge and discharge port 300 is transformed to charge the battery 400, or the voltage of the battery 400 is transformed and output through the DC charge and discharge port 300. If the integrated power system 100 operates in the second mode, the first end 11 is connected to the AC charge and discharge port 200, the second end 12 is connected to the battery 400, the third end 21 is connected to the AC charge and discharge port 200, and the fourth end 22 is connected to the battery 400, so that the voltage connected to the AC charge and discharge port 200 is rectified to charge the battery 400, or the voltage of the battery 400 is inverted and output through the AC charge and discharge port 200.

[0044] The integrated power system 100 of the embodiment of the present application can operate in a first mode or a second mode. In the first mode, the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can be used in combination as a DC transformer circuit, so that the DC voltage of the DC charge and discharge port 300 matches the voltage required for DC charging and discharging. In the second mode, the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit can both be used as an inverter circuit or a rectifier circuit, so that the integrated power system 100 is compatible with the function of AC charging and discharging. The first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can be used as an inverter circuit and a rectifier circuit, and can also be used in combination as a DC transformer circuit. The integrated power system 100 does not need to set up an additional DC / DC module to adjust the output voltage, which saves circuit resources to a large extent and reduces costs.

[0045] The first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can be used as an inverter circuit and a rectifier circuit, and can also be used in combination as a DC transformer circuit. The integrated power supply system 100 does not require an additional DC / DC module to adjust the output voltage, which saves circuit resources to a large extent and reduces costs.

[0046] Specifically, the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 may each include a DC connection terminal and an AC connection terminal. The first terminal 11 may be used as the AC connection terminal of the first bidirectional conversion circuit 10, and the second terminal 12 may be used as the DC connection terminal of the first bidirectional conversion circuit 10. The third terminal 21 may be used as the AC connection terminal of the second bidirectional conversion circuit 20, and the fourth terminal 22 may be used as the DC connection terminal of the second bidirectional conversion circuit 20.

[0047] by Figure 3 For example, the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can adopt a two-stage circuit topology in which the front stage circuit is a power factor correction circuit and the rear stage circuit is a DC-DC circuit. The power factor correction circuit can be coupled to the DC-DC circuit through a transformer M1.

[0048] In some embodiments, the power factor correction circuit may include transistors T1 to T10, an inductor La, an inductor Lb, an inductor Lr, a capacitor C1, a capacitor C2, and a capacitor Cr. The capacitor C2 may be connected in parallel with the capacitor C1. The transistor T1 and the transistor T2 may be connected in series at both ends of the capacitor C1. The transistor T3 and the transistor T4 may be connected in series at both ends of the capacitor C1. The transistor T5 and the transistor T6 may be connected in series at both ends of the capacitor C1. The transistor T7 and the transistor T8 may be connected in series at both ends of the capacitor C1. The transistor T9 and the transistor T10 may be connected in series at both ends of the capacitor C1. One end of the inductor La may be connected to one end of the capacitor C1, and the other end of the inductor La may be connected between the transistor T1 and the transistor T2. One end of the inductor Lb may be connected to one end of the capacitor C1, and the other end of the inductor Lb may be connected between the transistor T3 and the transistor T4. The other end of the capacitor C1 can be connected between the transistor T5 and the transistor T6. One end of the inductor Lr can be connected to the same-name end of the primary side of the transformer M1, and the other end of the inductor Lr can be connected between the inductor L7 and the inductor L8. One end of the capacitor Cr can be connected to the opposite-name end of the primary side of the transformer M1, and the other end of the capacitor Cr can be connected between the inductor L9 and the inductor La0. The two ends of the capacitor C1 can be set as the second end 12 of the first bidirectional conversion circuit 10, and can also be set as the fourth end 22 of the second bidirectional conversion circuit 20.

[0049] The DC-DC circuit may include transistors T11 to T14 and a capacitor C3. The transistor T11 and the transistor T12 may be connected in series at both ends of the capacitor C3. The transistor T13 and the transistor T14 may be connected in series at both ends of the capacitor C3. The primary end of the secondary side of the transformer M1 may be connected between the transistor T11 and the transistor T12, and the secondary side of the transformer M1 may be connected between the transistor T13 and the transistor T14.

[0050] The integrated power system 100 may further include a controller, which is configured to obtain charging and discharging information of the integrated power system 100, and control the corresponding switching devices to close or open according to the charging and discharging information, so as to control the connection relationship between the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 and the AC charging port, the DC charging port and the battery 400, so that the integrated power system 100 operates in the corresponding working mode.

[0051] by Figure 4 For example, the charging and discharging information of the integrated power system 100 may include DC gun state identification information, AC gun state identification information and in-vehicle AC power demand identification information. The controller may control the integrated power system 100 to operate in a corresponding operating mode according to whether the DC gun is connected, whether the AC gun is connected, and whether there is an in-vehicle charging demand.

[0052] Furthermore, the integrated power supply system 100 can also initiate emergency rescue for a specific power-consuming device, which can be a vehicle or other power-consuming device.

[0053] When a specific power-consuming device has an emergency rescue requirement, the integrated power supply system 100 can preferentially start the emergency rescue mode and convert the voltage of the battery 400 into a power supply voltage that matches the device to be rescued and provide it to the device to be rescued.

[0054] by Figure 5 For example, when a specific electrical equipment has an emergency rescue requirement, the integrated power system 100 can prioritize the emergency rescue mode. If the equipment to be rescued supports DC charging, the integrated power system 100 can operate in the first mode. If the rescue equipment does not support DC charging, the integrated power system 100 can operate in the second mode.

[0055] In the case where there is no emergency rescue demand for a specific power-consuming equipment, the integrated power supply system 100 can control the integrated power supply system 100 to work in the corresponding working mode according to whether the DC gun is connected, whether the AC gun is connected, and whether there is a need for in-vehicle charging. If a three-phase AC gun is connected, the integrated power supply system 100 can work in the second mode. If a single-phase AC gun is connected, the integrated power supply system 100 can work in the third mode. If there is a need for in-vehicle charging, the integrated power supply system 100 can work in the fourth mode. If a DC gun is connected, the integrated power supply system 100 can work in the fifth mode.

[0056] It should be noted that the integrated power supply system 100 can work in one working mode or in multiple working modes at the same time. For example, when the DC charging port is connected to a DC gun and the AC charging port is connected to a three-phase AC gun, the integrated power supply system 100 can work in the second mode and the fifth mode at the same time. When the DC charging port is connected to a DC gun, the AC charging port is connected to a three-phase AC gun, and there is a demand for power in the car, the integrated power supply system 100 can also work in the second mode, the fourth mode and the fifth mode at the same time.

[0057] The integrated power system 100 may not execute any working mode, and the integrated power system 100 is in an initialization state. The integrated power system 100 may further include a third bidirectional conversion circuit 30. The third bidirectional conversion circuit 30 includes a fifth terminal 31 and a sixth terminal 32. The third bidirectional conversion circuit 30 may convert an AC voltage connected to the fifth terminal 31 into a DC voltage outputted from the sixth terminal 32, or convert a DC voltage connected to the sixth terminal into an AC voltage outputted from the fifth terminal 31.

[0058] by Figure 3 For example, the circuit structure of the third bidirectional conversion circuit 30 may refer to the circuit structures of the first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20, which will not be described in detail herein.

[0059] The integrated power supply system 100 may further include a charging socket 40 and switch elements S1 to S7. The AC charging and discharging port 200 may include a terminal L1, a terminal L2, and a terminal L3. The switch element S1 may be connected between the terminal L3 and the first terminal 11. One end of the switch element S2 is connected to the second terminal 12, and the other end of the switch element S2 may be selectively connected to the DC charging and discharging port 300 and the battery 400. The switch element S3 may be connected to the terminal L2 and the switch element S4, one end of the switch element S4 is connected to the third terminal 21, and the other end of the switch element S4 may be selectively connected to the first terminal 11 or the switch element S3. The switch element S5 is connected between the terminal L1 and the fifth terminal 31. The switch element S6 is connected between the fifth terminal 31 and the charging socket 40. The switch element S7 is connected between the battery 400 and the DC charging and discharging port 300.

[0060] Reference Figure 2 When the integrated power system 100 is in the initialization state, the switch element S2 selects to connect the second terminal 12 and the battery 400, and the switch element S4 selects to connect the switch element S3 and the third terminal 21. The switch element S1, the switch element S3, the switch element S5, the switch element S6 and the switch element S7 are all disconnected.

[0061] Reference Figure 6 When the integrated power system 100 operates in the first mode, the battery 400 can be connected to the DC charging and discharging port 300 through the second bidirectional conversion circuit 20, the first bidirectional conversion circuit 10, and the first bidirectional conversion circuit 10. The second bidirectional conversion circuit 20 can convert the DC voltage provided by the battery 400 into a corresponding AC voltage and provide it to the first bidirectional conversion circuit 10, and the first bidirectional conversion circuit 10 then converts the AC voltage provided by the second bidirectional conversion circuit 20 into a corresponding DC voltage and provides it to the DC charging and discharging port 300.

[0062] Of course, the first bidirectional conversion circuit 10 can also convert the DC voltage provided by the DC charging and discharging port 300 into a corresponding AC voltage and provide it to the second bidirectional conversion circuit 20, and the second bidirectional conversion circuit 20 then converts the AC voltage provided by the first bidirectional conversion circuit 10 into a corresponding DC voltage and provides it to the battery 400 for charging. The first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can be used in combination to realize the function of a DC transformer circuit.

[0063] When a specific power-consuming device has an emergency rescue requirement, the integrated power system 100 can preferentially start the emergency rescue mode. If the device to be rescued supports DC charging, the integrated power system 100 can work in the first mode. The first bidirectional conversion circuit 10 and the second bidirectional conversion circuit 20 can transform the voltage according to the requirements of the device to be rescued, so that the output voltage of the DC charging and discharging port 300 matches the device to be rescued.

[0064] Reference Figure 7 In some embodiments, the integrated power system 100 may include a first switch 51, a second switch 52, a third switch 53, and a fourth switch 54. The first switch 51 is connected between the first terminal 11 and the AC charge and discharge port 200. The second switch 52 is configured to selectively connect the second terminal 12 with the battery 400, or connect the second terminal 12 with the DC charge and discharge port 300. The third switch 53 is connected between the AC charge and discharge port 200 and the fourth switch 54, and the fourth switch 54 is configured to selectively connect the third terminal 21 with the first terminal 11, or connect the third terminal 21 with the third switch 53. If the integrated power system 100 operates in the first mode, the first switch 51 and the third switch 53 are both disconnected, the second switch 52 is configured to connect the second terminal 12 with the DC charge and discharge port 300, and the fourth switch 54 is configured to connect the third terminal 21 with the first terminal 11.

[0065] Specifically, the first switch 51 can be set as a switch element S1 , the second switch 52 can be set as a switch element S2 , the third switch 53 can be set as a switch element S3 , and the fourth switch 54 can be set as a switch element S4 .

[0066] When the integrated power system 100 operates in the first mode, the switch element S4 selects to connect the first terminal 11 and the third terminal 21 , and the switch element S2 selects to connect the second terminal 12 and the DC charging and discharging port 300 .

[0067] Reference Figure 8 When the integrated power system 100 operates in the second mode, the battery 400 can be connected to the AC charge and discharge port 200 through the first bidirectional conversion circuit 10, the second bidirectional conversion circuit 20 or the third bidirectional conversion circuit 30. The first bidirectional conversion circuit 10, the second bidirectional conversion circuit 20 and the third bidirectional conversion circuit 30 can all invert the DC voltage provided by the battery 400, and provide the inverted AC voltage to the AC charge and discharge port 200, so that the AC charge and discharge port 200 can output a three-phase AC voltage.

[0068] In the case of emergency rescue needs for specific power-consuming equipment, the integrated power system 100 can preferentially start the emergency rescue mode. If the equipment to be rescued supports AC charging, the integrated power system 100 can work in the second mode, and the AC charging and discharging port 200 can provide the corresponding three-phase AC voltage. The first bidirectional conversion circuit 10, the second bidirectional conversion circuit 20, and the third bidirectional conversion circuit 30 can all be started according to the needs of the equipment to be rescued, so that the output voltage of the AC charging and discharging port 200 matches the equipment to be rescued.

[0069] When the AC charging and discharging port 200 is connected to a three-phase AC gun, the integrated power supply system 100 can also work in the second mode. The three-phase AC gun can provide AC voltage through the AC charging and discharging port 200, and the first bidirectional conversion circuit 10, the second bidirectional conversion circuit 20 and the third bidirectional conversion circuit 30 can all rectify the AC voltage and provide the rectified DC voltage to the battery 400 for charging. Of course, the first bidirectional conversion circuit 10, the second bidirectional conversion circuit 20 and the third bidirectional conversion circuit 30 can also invert the DC voltage provided by the battery 400 and provide the inverted three-phase AC voltage to the AC charging and discharging port 200.
