[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] Figure 1 A schematic diagram of a storage power supply provided by an embodiment of the present invention, referring to Figure 1, the energy storage power supply 10 includes a control module 11 and at least one connection module 12; the connection module 12 is used to connect the control module 11 of another energy storage power supply 10;

[0031] The control module 11 includes at least one first detection terminal A1, the first terminal B1 of the connection module 12 is electrically connected to the first detection terminal A1, and the second terminal B2 of the connection module 12 is used to connect to the control module 11 of another energy storage power supply 10; the control module 11 is used to determine whether the energy storage power supply 10 to which it belongs is self-starting or follow-starting according to the level of at least one first detection terminal A1 of itself within a preset time after being awakened; and when it is determined that the energy storage power supply 10 to which it belongs is self-starting, send a start signal to the other connected energy storage power supply 10 so that the other connected energy storage power supply 10 is awakened and started.

[0032] Exemplarily, each energy storage power source 10 may further include a starting switch, which is electrically connected to the energy storage power source 10. When the starting switch of an energy storage power source 10 is closed, the energy storage power source 10 is self-starting.

[0033] This embodiment exemplarily shows that two energy storage power supplies are included. For example, in this embodiment and the following embodiments, the energy storage power supply may be a first energy storage power supply 101, and the other energy storage power supply may be a second energy storage power supply 102 ( Figure 1 Only the control module of the second energy storage power supply 102 is shown, and the connection module included therein is not shown), and the first energy storage power supply 101 is exemplarily shown to include a connection module 12.

[0034] Exemplarily, the first energy storage power supply 101 determines the self-starting situation according to the level of its first detection terminal A1. When the first energy storage power supply 101 determines that the level of its first detection terminal A1 is high within the preset time after being awakened, it determines that it is self-starting, and after determining that it is self-starting, it sends a start signal to the connected second energy storage power supply 102 to wake up and start the second energy storage power supply 102; when the first energy storage power supply 101 determines that the level of its first detection terminal A1 is low within the preset time after being awakened, it determines that it is follow-starting, that is, the first energy storage power supply 101 is awakened and started by the second energy storage power supply 102.

[0035] In this embodiment, the energy storage power supply includes a control module and at least one connection module; the connection module is used to connect to the control module of another energy storage power supply; wherein the control module includes at least one first detection terminal, the first end of the connection module is electrically connected to a first detection terminal, and the second end of the connection module is used to connect to the control module of another energy storage power supply; the control module is used to determine whether the energy storage power supply is self-starting or follow-up starting according to the level of at least one first detection terminal of itself within a preset time after being awakened; and when the energy storage power supply is judged to be self-starting, a start signal is sent to the connected energy storage power supply so that the connected energy storage power supply is awakened and started. After the energy storage power supplies are connected, when one of the energy storage power supplies is self-started, the control module of the self-starting energy storage power supply can send a start signal to awaken and start the other connected energy storage power supply, thereby eliminating the need to self-start each energy storage power supply. When multiple energy storage power supplies are connected, the time to start all energy storage power supplies can be shortened, and labor can be saved.

[0036] Continue to refer Figure 1 Optionally, the connection module 12 is used to output a high level or a low level to the first detection end of the energy storage power supply 10 to which it belongs according to the startup state of the energy storage power supply 10 to which it belongs.

[0037] Exemplarily, when the starting switch connected to the first energy storage power supply 101 is closed to self-start the first energy storage power supply 101, the second energy storage power supply 102 is not awakened and started. At this time, the connection module 12 outputs a high level to the first detection terminal A1 of the first energy storage power supply 101, and the first energy storage power supply 101 determines that it is self-starting according to the high level of its own first detection terminal A1.

[0038] When the first energy storage power supply 101 determines that it is self-starting, the first energy storage power supply 101 can send a start signal to the second energy storage power supply 102 to wake up and start the second energy storage power supply 102. After the second energy storage power supply 102 is awakened and started, the connection module 12 connected to the first energy storage power supply 101 outputs a low level to the first detection terminal A1 of the first energy storage power supply 101. After the first energy storage power supply 101 determines that it is self-starting, it receives that the level of its own first detection terminal A1 becomes a low level, and determines that it is awakened and connected successfully to the second energy storage power supply 102. It is worth noting that within the preset time after the first energy storage power supply 101 is awakened, that is, when the second energy storage power supply 102 has not been awakened, the level of the first detection terminal A1 is high, and after the first energy storage power supply 101 determines that it is self-starting and wakes up the second energy storage power supply 102, the second energy storage power supply 102 outputs a low level to the first detection terminal A1 of the first energy storage power supply 101 through the connection module 12, and the first energy storage power supply 101 determines that the second energy storage power supply is awakened and started and the connection is successful through the low level of the first detection terminal A1.

[0039] Figure 2A schematic diagram of another energy storage power supply provided by an embodiment of the present invention, referring to Figure 2 Optionally, the connection module 12 includes a first photoelectric sensor 121, the first photoelectric sensor 121 includes a first end E1, a second end E2, a third end E3 and a fourth end E4, the first end of the first photoelectric sensor 121 serves as the first end B1 of the connection module 12, the second end of the first photoelectric sensor 121 serves as the second end B2 of the connection module 12, the third end E3 of the first photoelectric sensor 121 is electrically connected to the first ground point GND1, and the fourth end E4 is electrically connected to the second ground point GND2;

[0040] The first photoelectric sensor 121 is used to generate a light signal when its second end E2 receives a start signal from another energy storage power supply 10, and output an electrical feedback signal to the first detection end A1 of the energy storage power supply 10 to which it belongs through its first end E1 based on the light signal, wherein the electrical feedback signal is opposite to the signal level of the judgment that the energy storage power supply 10 is self-starting, and the control module 11 is used to determine that the energy storage power supply 10 to which it belongs is connected with another energy storage power supply 10 according to the electrical feedback signal received by the first detection end A1 of the energy storage power supply 10 to which it belongs.

[0041] A photosensitive semiconductor tube is connected between the first end E1 and the third end E3 of the first photoelectric sensor 121, and a light-emitting diode is connected between the second end E3 and the fourth end E4 of the first photoelectric sensor 121. When the second end E2 of the first photoelectric sensor 121 is at a high level, the light-emitting diode emits light, and the photosensitive semiconductor tube generates a photocurrent after receiving the light, which is output from the first end E1, thereby realizing the "electric-light-electric" conversion.

[0042] When the second end E2 of the first photoelectric sensor 121 receives the start signal of the control module 11 of the second energy storage power supply 102, the start signal is at a high level, and the light-emitting diode of the first photoelectric sensor 121 emits light, that is, sends out a light signal, and the photosensitive semiconductor tube is turned on after receiving the light signal, thereby pulling the level of the first end E1 to a low potential, that is, the first end E1 of the first photoelectric sensor 121 itself outputs a low level (electrical feedback signal) to the first energy storage power supply 101, and the first detection end A1 of the control module 11 of the first energy storage power supply 101 determines that it is connected to the started second energy storage power supply 102 according to the received low level.

[0043] Figure 3 A schematic diagram of another energy storage power supply provided by an embodiment of the present invention, referring to Figure 3Optionally, the control module 11 includes a control unit 111 and at least one starting unit 112, the starting unit 112 corresponds to the connection module 12 one by one, the control unit 111 includes a first detection terminal A1, the control unit 111 also includes a first output terminal U1, the first output terminal U1 and the first detection terminal A1 appear in pairs; the starting unit 112 includes a first terminal F1 and a second terminal F2, the first terminal F1 of the starting unit 112 is electrically connected to the first output terminal U1, and the second terminal F2 of the starting unit 112 is used to connect to the control module 11 of another energy storage power supply 10;

[0044] The control unit 111 is used to output a first startup control signal to the first terminal F1 of the startup unit 112 through its own first output terminal U1 when it is determined that the energy storage power supply 10 to which it belongs is self-starting. The startup unit 112 is used to output a second startup control signal through its own second terminal F2 according to the first startup control signal of its own first terminal F1, so that another connected energy storage power supply 10 is awakened and started.

[0045] Optionally, the control unit 111 may be a DSP chip. Specifically, the second terminal F2 of the start-up unit 112 is electrically connected to the first detection terminal A1 of the control unit of the second energy storage power supply 102, and the second terminal B2 of the connection module 12 is electrically connected to the first output terminal U1 of the control unit of the second energy storage power supply 102. In this embodiment, the control module of the second energy storage power supply 102 is only exemplarily drawn to include the control unit 111, and the start-up unit is not shown. Exemplarily, after the first energy storage power supply 101 determines that it is self-starting, it outputs a first start-up control signal to the first terminal F1 of the start-up unit 112, and the start-up unit 112 generates a second start-up control signal according to the first start-up control signal of the first terminal F1, and outputs the second start-up control signal to the first detection terminal A1 of the second energy storage power supply 102 to wake up and start the second energy storage power supply 102.

[0046] Continue to refer Figure 3 Optionally, the starting unit 112 includes a second photoelectric sensor 1121, the second photoelectric sensor 1121 includes a fifth end E5, a sixth end E6, a seventh end E7 and an eighth end E8, the fifth end E5 of the second photoelectric sensor 1121 serves as the first end F1 of the starting unit 112, the sixth end E6 of the second photoelectric sensor 1121 serves as the second end F2 of the starting unit 112, the seventh end E7 of the second photoelectric sensor 1121 is electrically connected to the third ground point GND3, and the eighth end E8 is electrically connected to the fourth ground point GND4;

[0047] The second photoelectric sensor 1121 is used to generate a light signal when its fifth end E5 receives a first start-up control signal, and output a second start-up control signal to the first detection end A1 of another connected energy storage power supply 10 through its sixth end E6 based on the light signal to wake up and start the other connected energy storage power supply 10.

[0048] A photosensitive semiconductor tube is connected between the sixth terminal E6 and the eighth terminal E8 of the second photoelectric sensor 1121, and a light emitting diode is connected between the fifth terminal E5 and the seventh terminal E7 of the second photoelectric sensor 1121. The first start control signal is high level, and the second start control signal is low level.

[0049] After the first energy storage power supply 101 determines that it has started, it outputs a first start-up control signal to the fifth terminal E5 of the start-up unit 1121 via the first output terminal U1, and the light emitting diode of the start-up unit 1121 is turned on to emit light, generating a light signal. After receiving the light signal, the photosensitive semiconductor tube of the start-up unit 1121 is turned on, and the potential of the sixth terminal E6 is pulled down, and then the second start-up control signal is output to the first detection terminal A1 of the second energy storage power supply 102 via the sixth terminal E6, so as to wake up and start the second energy storage power supply 102.

[0050] Continue to refer Figure 3 Optionally, the control unit 111 is used to determine whether the energy storage power supply 10 to which it belongs is a follow-up start, the previous-level energy storage power supply 10 is a self-starting energy storage power supply 10 or the previous-level follow-start energy storage power supply 10 according to the level of the first detection terminal A1 electrically connected to the previous-level energy storage power supply 10.

[0051] Exemplarily, the second energy storage power supply 102 determines that it is a follow-up start-up according to the level of its first detection terminal A1 being low, that is, the second energy storage power supply 102 is awakened and started by the first energy storage power supply 101. When the first energy storage power supply 101 is self-starting, the second energy storage power supply 102 is awakened and started by the self-starting first energy storage power supply 101; in other embodiments, when the first energy storage power supply 101 is a follow-up start-up, the second energy storage power supply 102 is awakened and started by the follow-starting first energy storage power supply 101.

[0052] Continue to refer Figure 3 Optionally, the control unit 111 is also used to send a start signal to the corresponding upper-level energy storage power supply 10 through its first output terminal U1 when it determines that the energy storage power supply 10 to which it belongs is to follow the start.

[0053] Exemplarily, after the control unit 111 of the second energy storage power supply 102 determines that it is a follow-up start-up through the low level of its own first detection terminal A1, it sends a start signal, that is, a high level, to the first energy storage power supply 101 through its own first output terminal U1. Then, after the second terminal E2 of the first photoelectric sensor 121 receives the start signal, it generates a light signal and converts it into an electrical feedback signal, that is, a low level, which is output to the first detection terminal A1 of the first energy storage power supply 101 through its own first terminal E1. After receiving the low level, the first detection terminal A1 determines that the second energy storage power supply 102 is awakened and started successfully, and is successfully connected to the second energy storage power supply 102.

[0054] Optionally, each energy storage power supply 10 may also include a communication module, and any two energy storage power supplies 10 may exchange information through their respective communication modules. When the first energy storage power supply 101 determines that it is self-starting, it may set itself as the host, and when it determines that the second energy storage power supply 102 is awakened and started successfully, and when it determines that the second energy storage power supply 102 is successfully connected to itself, it may exchange information with the second energy storage power supply 102 through the communication module, and set the second energy storage power supply as slave No. 2. When the host is successfully connected to multiple slaves and outputs to the power supply device together, the voltage values ​​of the multiple energy storage power supplies 10 should be kept consistent as much as possible. Therefore, the host can transmit its own voltage value information to each slave through the communication module. After each slave receives the voltage value information of the host, it can adjust its own voltage value to keep consistent with the voltage value of the host.

[0055] Figure 4 A schematic diagram of another energy storage power supply provided by an embodiment of the present invention, referring to Figure 4 Optionally, the control unit 111 includes two first detection terminals A1 and two first output terminals U1. The control unit 111 is also used to determine that when the energy storage power supply 10 to which it belongs is a follow-up start, it sends a start signal to the corresponding next-level follow-up start energy storage power supply through its own first output terminal U1, so that the next-level follow-up start energy storage power supply connected is awakened and started.

[0056] In this embodiment, the control unit 111 of the second energy storage power supply 102 includes two first detection terminals A1 and two first output terminals U1, wherein one set of the first detection terminals A1 and the first output terminals U1 are used to be connected to the first energy storage power supply 101, and the other set of the first detection terminals A1 and the first output terminals U1 are used to be electrically connected to the third energy storage power supply 103. It is worth noting that each grounding point in different energy storage power supplies is different.

[0057] After the second energy storage power supply 102 is awakened and started by the first energy storage power supply 101, the second energy storage power supply 102 outputs a high level signal to the start-up unit 112 of the second energy storage power supply 102 through its own first output terminal U1, and the second terminal F2 of the start-up unit 112 outputs a low level to the first detection terminal of the third energy storage power supply to awaken and start the third energy storage power supply 103. After the third energy storage power supply 103 determines that it is awakened and started according to the low level of its own first detection terminal A1, it outputs a high level to the second terminal B2 of the connection module 12 of the second energy storage power supply 102 through its own first output terminal U1, and the connection module 12 outputs a low level to the first detection terminal A1 of the second energy storage power supply 102, so that the second energy storage power supply 102 determines that it has been awakened and started and successfully connected to the third energy storage power supply 103. The second energy storage power supply 102 is also used to transmit information that the second energy storage power supply (slave No. 2) has successfully awakened and started and successfully connected to the third energy storage power supply 103 to the first energy storage power supply 101 (host) through its own communication module. The first energy storage power supply 101 sets the third energy storage power supply 103 as slave No. 3 through the communication module. When the third energy storage power supply 103 is also connected to the fourth energy storage power supply, the process of waking up and setting the fourth energy storage power supply 103 as a slave is similar to the above process, and so on.

[0058] Exemplarily, when all N energy storage power supplies are awakened and started successfully, N is a positive integer, and the host determines to enter the mode of parallel operation of N energy storage power supplies. As the working process proceeds, when the Mth energy storage power supply no longer outputs a low level to the first detection terminal of the M-1th energy storage power supply through the connection module of the M-1th energy storage power supply, the M-1th energy storage power supply determines that the Mth energy storage power supply has power-off protection, and transmits this information to the host through the communication module, and the host further determines to enter the mode of parallel operation of N-1 energy storage power supplies. Wherein, M is a positive integer and is less than or equal to N.

[0059] An embodiment of the present invention further provides a control system, which includes at least two energy storage power supplies in the above embodiments.

The control module 11 is used to control the inverter module 02 to start inversion to convert the direct current of the battery module 01 into alternating current. The first end of the detection module 04 is electrically connected to the switch module 03, the second end of the detection module 04 is electrically connected to the third end of the control module 11, and the fourth end of the control module 11 is also electrically connected to the switch module 03.
