It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0026] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all the embodiments.

[0027] Figure 1 It is a schematic structural diagram of a power supply system provided by an embodiment of the present disclosure, Figure 2 It is a schematic connection diagram of a power supply component and a voltage output circuit in the power supply system provided by an embodiment of the present disclosure. Referring to Figure 1 and Figure 2 , this embodiment provides a power supply system, including:

[0028] A power supply component 10, the power supply component 10 includes a plurality of power storage modules 11, the positive electrode of the power storage module 11 is connected with a detection device 12 and a first switch K1, and the detection device 12 is used for detecting the operation parameters of the power storage module 11 connected thereto;

[0029] A voltage output circuit 20, the voltage output circuit 20 includes a plurality of input ends 21 and at least two output ends 22, and different output ends 22 are used for outputting different voltages;

[0030] A connection guiding device 30;

[0031] A control unit 40, the control unit 40 is electrically connected to each detection device 12 and each first switch K1, the control unit 40 is used for controlling the switch state of the first switch K1 electrically connected thereto according to the signal of the detection device 12, the control unit 40 is also electrically connected to the connection guiding device 30, and the control unit 40 is also used for controlling the connection guiding device 30 to be connected with the input end 21 and controlling the connection between the input end 21 and the power storage module 11 through the connection guiding device 30.

[0032] Specifically, the power supply system provided by the embodiments of the present disclosure includes a power supply component 10 and a voltage output circuit 20. The power supply component 10 includes a plurality of energy storage modules 11. The voltage output circuit 20 includes a plurality of input terminals 21 and at least two output terminals 22. The input terminals 21 are used for electrically connecting with the energy storage modules 11. After the energy storage modules 11 are electrically connected to the input terminals 21, different output terminals 22 in the voltage output circuit 20 can output different voltages, so as to realize power supply to electrical devices with different rated voltages.

[0033] A detection device 12 and a first switch K1 are connected to the positive electrode of the energy storage module 11. The detection device 12 is used for detecting the operating parameters of the energy storage module 11 connected thereto. The control unit 40 is electrically connected to each detection device 12 and each first switch K1. The control unit 40 is used for controlling the switch state of the first switch K1 electrically connected thereto according to the signal of the detection device 12. That is, the detection device 12 can detect the operating parameters of the energy storage module 11 connected thereto. The control unit 40 determines whether the energy storage module 11 meets the power consumption requirements according to the operating parameters of the energy storage module 11 detected by the detection device 12. When the energy storage module 11 meets the power consumption requirements, the control unit 40 controls the first switch K1 electrically connected to the energy storage module 11 to be in a closed state. When the energy storage module 11 does not meet the power consumption requirements, the control unit 40 controls the first switch K1 electrically connected to the energy storage module 11 to be in an open state.

[0034] The control unit 40 is also electrically connected to the connection guiding device 30. The control unit 40 is also used for controlling the connection guiding device 30 to be connected to the input terminal 21 and controlling the input terminal 21 to be connected to the energy storage module 11 through the connection guiding device 30. That is, the control unit 40 controls the guiding device 30 to be connected to an input terminal 21, and then the connection guiding device 30 electrically connects the input terminal 21 to the energy storage module 11 that meets the power consumption requirements. Then, the guiding device 30 is disconnected from the input terminal 21 and connected to another input terminal 21. The above steps are repeated until all the input terminals 21 are electrically connected to the energy storage modules 11 that meet the power consumption requirements, so as to realize connecting the energy storage modules 11 that meet the power consumption requirements to each input terminal 21 in the voltage output circuit 20, thereby effectively improving the power supply stability of the power supply system.

[0035] Optionally, the control unit 40 is further configured to memorize the connection status between the voltage output circuit 20 and each energy storage module 11. After power-off, the connection between the voltage output circuit 20 and each energy storage module 11 is not disconnected. After power-on again, when each detection device 12 detects that the energy storage module 11 electrically connected to the voltage output circuit 20 meets the power consumption requirements, the guiding device 30 does not work. When each detection device 12 detects that the energy storage module 11 electrically connected to the voltage output circuit 20 does not meet the power consumption requirements, the guiding device 30 disconnects the energy storage module 11 that does not meet the power consumption requirements from the input terminal 21, and electrically connects the input terminal 21 to the energy storage module 11 that meets the power consumption requirements.

[0036] Optionally, the energy storage module 11 may be at least one of a lead-acid battery, a nickel-metal hydride battery, a lithium iron phosphate battery, a lithium cobalt oxide battery, a lithium titanate battery, a supercapacitor power battery, and a lithium-ion capacitor. Of course, in other embodiments of the present disclosure, the energy storage module 11 may also adopt other energy modules, which are not elaborated herein one by one.

[0037] It should be noted that the specific structure of the first switch K1 is not limited in the embodiments of the present disclosure, as long as the first switch K1 can control the connection state of the positive electrode of the energy storage module 11 electrically connected thereto through its switch state. For example, the first switch K1 may be an electronic switch, such as a triode or an MOS transistor, etc. For details, reference may be made to the related art, and the present disclosure will not introduce it in detail.

[0038] Continue to refer to Figure 1 and Figure 2 , in some alternative embodiments, the connection guiding device 30 includes a front sniffing probe and a suction stepping motor.

[0039] Specifically, the front sniffing probe and the suction stepping motor are connected to an input terminal 21. Then, when the front sniffing probe detects that the positive electrode of a certain energy storage module 11 has a voltage, the front sniffing probe sends a signal, indicating that the first switch K1 electrically connected to the positive electrode of the energy storage module 11 is in a closed state, that is, the energy storage module 11 is an energy storage module 11 that meets the power consumption requirements. The suction stepping motor electrically connects the input terminal 21 to the energy storage module 11 that meets the power consumption requirements. Then, the front sniffing probe and the suction stepping motor are disconnected from the input terminal 21 and connected to another input terminal 21, and the above steps are repeated until all input terminals 21 are electrically connected to the energy storage module 11 that meets the power consumption requirements, so as to connect the energy storage module 11 that meets the power consumption requirements to each input terminal 21 in the voltage output circuit 20, thereby effectively improving the power supply stability of the power supply system.

[0040] It should be noted that in the exemplary embodiment of the present disclosure, the connection guiding device 30 is shown to include a front sniffing probe and a suction stepping motor. In other embodiments of the present disclosure, the connection guiding device 30 may also be other devices capable of electrically connecting the input end 21 to the power storage module 11 that meets the power consumption requirements, which will not be elaborated herein one by one.

[0041] Continuing to refer to Figure 1 and Figure 2 , in some alternative embodiments, the input end 21 includes a positive input end 211 and a negative input end 212. The positive input end 211 is connected to a second switch K2, and the negative input end 212 is connected to a third switch K3. The second switch K2 is used to be electrically connected to the positive electrode of the power storage module 11, and the third switch K3 is used to be electrically connected to the negative electrode of the power storage module 11.

[0042] Specifically, the front sniffing probe and the suction stepping motor are first connected to the front section of the second switch K2 connected to an input end 21. Then, when the front sniffing probe detects that the positive electrode of a certain power storage module 11 has a voltage, the front sniffing probe sends a signal indicating that the first switch K1 electrically connected to the positive electrode of this power storage module 11 is in the closed state, that is, this power storage module 11 is the power storage module 11 that meets the power consumption requirements. The suction stepping motor inserts and connects the front section of this second switch K2 to the positive electrode of the power storage module 11 that meets the power consumption requirements. Then, the front sniffing probe and the suction stepping motor are disconnected from the front section of the second switch K2 connected to this input end 21. The suction stepping motor is connected to the front section of the third switch K3 connected to this input end 21, and the suction stepping motor inserts and connects the front section of this third switch K3 to the negative electrode of the closest power storage module 11, thereby realizing the connection between this power storage module 11 and this input end 21. The suction stepping motor is disconnected from the front section of the third switch K3 connected to this input end 21. The front sniffing probe and the suction stepping motor are connected to the front section of the second switch K2 connected to another input end 21, and the above steps are repeated until all input ends 21 are electrically connected to the power storage module 11 that meets the power consumption requirements, thereby realizing the connection of the power storage module 11 that meets the power consumption requirements to each input end 21 in the voltage output circuit 20, thereby effectively improving the power supply stability of the power supply system.

[0043] It should be noted that the present disclosure embodiment does not limit the specific structure of the second switch K2, as long as the second switch K2 can control its connection state with the positive electrode of the power storage module 11 through its switch state. Similarly, the present disclosure embodiment does not limit the specific structure of the third switch K3, as long as the third switch K3 can control its connection state with the negative electrode of the power storage module 11 through its switch state. For example, the second switch K2 and the third switch K3 can adopt electronic switches, such as triodes or MOS tubes, etc. For details, reference can be made to the related art, and the present disclosure will not introduce it in detail.

[0044] Continue to refer to Figure 1 and Figure 2 In some alternative embodiments, the output terminal 22 includes a first output terminal 221 and a second output terminal 222. The voltage output from the first output terminal 221 is greater than the voltage output from the second output terminal 222. The first output terminal 221 can be used to supply power to an electrical device with a relatively large rated voltage, and the second output terminal 222 can be used to supply power to an electrical device with a relatively small rated voltage. Exemplarily, the voltage output from the first output terminal 221 is 48V, so that the first output terminal 221 can be used to supply power to an electrical device with a rated voltage of 48V. The voltage output from the second output terminal 222 is 12V, so that the second output terminal 222 can be used to supply power to an electrical device with a rated voltage of 12V.

[0045] It should be noted that in this exemplary embodiment, the output terminal 22 includes the first output terminal 221 and the second output terminal 222. In other embodiments of the present disclosure, the output terminal 22 may further include other output terminals, and the voltage output from these output terminals is different from the voltages output from the first output terminal 221 and the second output terminal 222. Details are not elaborated herein one by one.

[0046] Figure 3 is another connection schematic diagram of the power supply component and the voltage output circuit in the power supply system provided by the embodiment of the present disclosure. Refer to Figure 1 and Figure 3 In some alternative embodiments, the voltage output circuit 20 includes a first circuit branch 23. The first circuit branch 23 includes a plurality of input terminals 21 connected in series. Both ends of the first circuit branch 23 are electrically connected to the first output terminal 221;

[0047] One of the input terminals 21 in the first circuit branch 23 is electrically connected to the second output terminal 222.

[0048] Specifically, the voltage output circuit 20 includes a first circuit branch 23. The first circuit branch 23 includes a plurality of input terminals 21 connected in series. Both ends of the first circuit branch 23 are electrically connected to the first output terminal 221. That is, in the first circuit branch 23, the positive input terminal 211 of the input terminal 21 at the head end among the series-connected plurality of input terminals 21 is electrically connected to the positive output terminal of the first output terminal 221, and the negative input terminal 212 of the input terminal 21 at the tail end among the series-connected plurality of input terminals 21 is electrically connected to the negative output terminal of the first output terminal 221. Thus, after each input terminal 21 in the first circuit branch 23 is connected to each energy storage module 11, the energy storage modules 11 electrically connected to each input terminal 21 in the first circuit branch 23 are connected in series, so that the first output terminal 221 can output a relatively large voltage. One of the input terminals 21 in the first circuit branch 23 is electrically connected to the second output terminal 222, so that the second output terminal 222 can output a relatively small voltage.

[0049] It should be noted that Figure 3Exemplarily shown in [the figure], the first circuit branch 23 includes 4 input terminals 21 connected in series. In other embodiments of the present disclosure, the first circuit branch 23 may also include other numbers of input terminals 21 connected in series, which will not be elaborated one by one herein.

[0050] It should be noted that Figure 3 Exemplarily shown in [the figure], the second output terminal 222 is electrically connected to the input terminal 21 at the end among the multiple input terminals 21 connected in series in the first circuit branch 23. In other embodiments of the present disclosure, the second output terminal 222 may also be electrically connected to other input terminals 21 among the multiple input terminals 21 connected in series in the first circuit branch 23, and the present disclosure does not make specific limitations thereto.

[0051] Figure 4 It is another connection schematic diagram of the power supply component and the voltage output circuit in the power supply system provided by the embodiments of the present disclosure. Referring to Figure 1 and Figure 4 , in some alternative embodiments, the voltage output circuit 20 further includes a second circuit branch 24. The second circuit branch 24 includes one input terminal 21, and both ends of the second circuit branch 24 are electrically connected to the second output terminal 222;

[0052] A fourth switch K4 is provided between the positive input terminal 211 of the input terminal 21 in the second circuit branch 24 and the positive input terminal 211 of the input terminal 21 in the first circuit branch 23;

[0053] The negative input terminal 212 of the input terminal 21 in the second circuit branch 24 is electrically connected to the negative input terminal 212 of the input terminal 21 in the first circuit branch 23;

[0054] The control unit 40 is electrically connected to the fourth switch K4.

[0055] Specifically, the voltage output circuit 20 further includes a second circuit branch 24. The second circuit branch 24 includes one input terminal 21, that is, the input terminal 21 of the second circuit branch 24 can be electrically connected to a power storage module 11. Both ends of the second circuit branch 24 are electrically connected to the second output terminal 222. Thus, when after each input terminal 21 in the first circuit branch 23 is electrically connected to the power storage module 11 that meets the power consumption requirements and there is still a power storage module 11 that meets the power consumption requirements, the input terminal 21 of the second circuit branch 24 can be electrically connected to the power storage module 11 that meets the power consumption requirements. After the input terminal 21 in the second circuit branch 24 is electrically connected to the power storage module 11, the second output terminal 222 can output a smaller voltage.

[0056] Meanwhile, a fourth switch K4 is provided between the positive input terminal 211 of the input terminal 21 in the second circuit branch 24 and the positive input terminal 211 of the input terminal 21 in the first circuit branch 23. The negative input terminal 212 of the input terminal 21 in the second circuit branch 24 is electrically connected to the negative input terminal 212 of the input terminal 21 in the first circuit branch 23. The control unit 40 is electrically connected to the fourth switch K4. Thus, when the instantaneous current output at the first output terminal 221 and the second output terminal 222 is insufficient, the control unit 40 can control the fourth switch K4 to close, and the two power storage modules 11 electrically connected to the second output terminal 222 are formed in parallel, and the current flows bidirectionally and supplements each other as needed. After the supplement is completed, the control unit 40 controls the fourth switch K4 to disconnect, which can improve the stability of the current output at the first output terminal 221 and the second output terminal 222, and further improve the power supply stability of the power supply system.

[0057] It should be noted that the specific structure of the fourth switch K4 in the embodiments of the present disclosure is not limited, as long as the connection state between the second output terminal 222 and the positive input terminal 211 of the input terminal 21 in the first circuit branch 23 electrically connected thereto can be controlled by the switch state of the fourth switch K4. For example, the fourth switch K4 can adopt an electronic switch, such as a triode or a MOS transistor, etc. For details, reference can be made to the related art, and the present disclosure will not introduce it in detail.

[0058] Figure 5 is another connection schematic diagram of the power supply component and the voltage output circuit in the power supply system provided by the embodiments of the present disclosure. Refer to Figure 1 and Figure 5 , in some alternative embodiments, the voltage output circuit 20 further includes at least one third circuit branch 25. The third circuit branch 25 includes an input terminal 21. The positive input terminal 211 of the input terminal 21 in the third circuit branch 25 is electrically connected to the positive input terminal 211 of the input terminal 21 in the second circuit branch 24, and a fifth switch K5 is provided therebetween. The negative input terminal 212 of the input terminal 21 in the third circuit branch 25 is electrically connected to the negative input terminal 212 of the input terminal 21 in the second circuit branch 24;

[0059] The control unit 40 is electrically connected to the fifth switch K5.

[0060] Specifically, the voltage output circuit 20 further includes a third circuit branch 25. The third circuit branch 25 includes an input terminal 21. That is, the input terminal 21 of the third circuit branch 25 can be electrically connected to a power storage module 11. Thus, when the input terminals 21 in the first circuit branch 23 are electrically connected to the power storage modules 11 that meet the power consumption requirements, and the input terminals 21 in the second circuit branch 24 are electrically connected to the power storage modules 11 that meet the power consumption requirements, and there are still power storage modules 11 that meet the power consumption requirements, the input terminal 21 of the third circuit branch 25 can be electrically connected to the power storage module 11 that meets the power consumption requirements. The positive input terminal 211 of the input terminal 21 in the third circuit branch 25 is electrically connected to the positive input terminal 211 of the input terminal 21 in the second circuit branch 24, and a fifth switch K5 is provided therebetween. The negative input terminal 212 of the input terminal 21 in the third circuit branch 25 is electrically connected to the negative input terminal 212 of the input terminal 21 in the second circuit branch 24. The control unit 40 is electrically connected to the fifth switch K5. Thus, when the instantaneous current output from the second output terminal 222 is insufficient, the control unit 40 can control the fifth switch K5 to close, forming a parallel connection with the power storage modules 11 electrically connected to the second output terminal 222, and the current can be supplemented to the power storage modules 11 electrically connected to the input terminal 21 in the second circuit branch 24. After the supplementation is completed, the control unit 40 controls the fifth switch K5 to open, which can improve the stability of the current output from the second output terminal 222 and further improve the power supply stability of the power supply system.

[0061] It should be noted that the specific structure of the fifth switch K5 is not limited in the embodiments of the present disclosure. As long as the connection state between the positive input terminal 211 of the input terminal 21 in the third circuit branch 25 and the positive input terminal 211 of the input terminal 21 in the second circuit branch 24 can be controlled by the switch state of the fifth switch K5. For example, the fifth switch K5 can be an electronic switch, such as a triode or a MOS transistor, etc. For details, reference can be made to the related technologies, and the present disclosure will not elaborate on this.

[0062] It should be noted that Figure 5 exemplarily shows that the voltage output circuit 20 includes a third circuit branch 25. In other embodiments of the present disclosure, the voltage output circuit 20 may further include two or more third circuit branches 25. Correspondingly, the input terminals 21 of each third circuit branch 25 can be electrically connected to the power storage modules 11 that meet the power consumption requirements. The specific connection method can refer to Figure 5 the connection method of the third circuit branch 25 in

[0063] Continuing to refer to Figure 1 and Figure 2, in some alternative embodiments, the detection device 12 includes a voltage detection device for detecting the operating voltage of the power storage module 11 connected thereto. Thus, it is possible to determine whether the power storage module 11 meets the power consumption standard based on the operating voltage of the power storage module 11.

[0064] It should be noted that the exemplary embodiment of the present disclosure shows that the detection device 12 includes a voltage detection device. In other embodiments of the present disclosure, the detection device 12 may further include other detection devices, which will not be elaborated herein.

[0065] Continue to refer to Figure 1 and Figure 2 , in some alternative embodiments, the capacities of the power storage modules 11 are the same. Thus, as long as each power storage module 11 meets the power consumption requirements, it can be connected to any one of the input terminals 21 of the voltage output circuit 20, effectively simplifying the setup difficulty of the power supply system and reducing the production cost.

[0066] Exemplarily, the capacity of each power storage module 11 may be 12V. The capacities of the power storage modules 11 are relatively small, which can make full use of the idle small corner spaces of the vehicle and occupy as little storage space as possible.
