[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort fall within the scope of protection of the present application.

[0038] It should be noted that the terms used in the embodiments of the present application are merely for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means and includes any or all possible combinations of one or more associated listed items.

[0039] Referring to Figure 1 , Figure 1 The energy storage power supply 10 provided by the embodiments of the present application has a multifunctional interface, and comprises at least one group of main batteries 11, a main control board 12, a charging input interface 13, a discharging output interface 14 and a multifunctional interface 15, which are electrically connected.

[0040] The charging input interface 13 is an interface for connecting an external power supply.

[0041] The discharging output interface 14 is an interface for outputting power, and the number of the discharging output interface 14 can be one or more.

[0042] The multifunctional interface 15 is an interface allowing connection of at least two functional devices, and the two functional devices include a vehicle starting controller and a secondary battery, and can further include other functional devices having a power supply function or driven by a battery. It should be noted that "allowing connection of at least two functional devices" means that in different use scenarios, the vehicle starting controller or the secondary battery or other functional devices are connected each time, rather than two or more functional devices being connected at the same time.

[0043] The multifunctional interface 15 can be composed of two or more independent ports (for example, one independent port for the positive electrode and one independent port for the negative electrode), or can be an integrally formed port. The multifunctional interface 15 has at least a positive electrode port and a negative electrode port, and the positive electrode port and the negative electrode port of the multifunctional interface 15 are respectively used for connecting the positive electrode port and the negative electrode port of the functional device. In the embodiments of the present application, the multifunctional interface 15 can automatically identify the type of the connected functional device, so that the main control board 12 can set the corresponding function.

[0044] In some embodiments, the positive and negative terminals of the multifunctional interface 15 are shaped differently, i.e. the external functional device insertion is only positive terminal insertion into the positive terminal and negative terminal insertion into the negative terminal, and if the insertion is reversed, it cannot be inserted, preventing the positive and negative terminals from being reversed.

[0045] The "main battery" and "auxiliary battery" referred to herein are mainly used to distinguish the ownership of the battery, i.e. the main battery belongs to the energy storage power supply 10, and the auxiliary battery belongs to the external functional device.

[0046] In some embodiments, at least one group of main batteries 11 can be a lithium battery pack.

[0047] In some embodiments, the auxiliary battery can also be a lithium battery or a lithium battery pack.

[0048] In some embodiments, the number of main batteries is multiple groups, and the multiple groups of main batteries are connected in parallel and / or series.

[0049] The main control board 12 provides control and signal processing functions, is responsible for data sampling, charging and control of all output ports, and can be used to identify the currently connected functional device, and then determine the current working mode of the energy storage power supply.

[0050] The main control board 12 can control the charging of the energy storage power supply 10, the DC or AC output of the energy storage power supply 10, can identify the function of the device connected to the multifunctional interface 15, and set the interface as the corresponding function.

[0051] The main control board 12 can interact with the on-off control 16, which is used to control the connection or disconnection of the path between the main battery and the multifunctional interface.

[0052] The main control board 12 can also identify whether the charging input interface 13 is connected to an external power supply, i.e. whether it is in a charging state.

[0053] In some embodiments, the main control board 12 can be on the same board as the battery protection board, i.e. the two are integrated on the same functional board.

[0054] In some embodiments, the main control board 12 can be separate from the battery protection board and independently arranged.

[0055] The connection relationship, position, etc. of the above-mentioned components in the figure are only used to explain the scheme of the present application and are not limited, and the energy storage power supply 10 can also include more other components.

[0056] As mentioned above, when the multifunctional interface 15 of the energy storage power supply 10 is connected to different functional devices, it can be automatically set to different charging and discharging modes, which will be explained in detail below.

[0057] Referring to Figure 2 , Figure 2The working scenario of the multifunctional interface 15 of the energy storage power supply 10 connected to the automobile starting controller 21 is shown. The automobile starting controller 21 can be automatically recognized by the multifunctional interface as a starting function output port.

[0058] Specifically, when the multifunctional interface is currently connected to the vehicle starting controller, the main control board determines that the current working mode of the energy storage power supply is the vehicle starting mode, the on-off control 16 controls the passage to be in the connected state, and then the main battery is discharged to output power to the vehicle starting controller through the multifunctional interface.

[0059] Referring to Figure 3 and Figure 4 , Figure 3 and Figure 4 , two working scenarios of the multifunctional interface 15 of the energy storage power supply 10 connected to the auxiliary battery 22 are shown. When the multifunctional interface of the energy storage power supply is connected to the auxiliary battery, the auxiliary battery can be automatically recognized, and then the auxiliary battery can be charged when the energy storage power supply is charging, and the auxiliary battery can provide discharge power when discharging.

[0060] Specifically, when the multifunctional interface is currently connected to the vehicle starting controller, the main control board determines that the current working mode of the energy storage power supply is the vehicle starting mode, the on-off control 16 controls the passage to be in the connected state, and then the main battery is discharged to output power to the vehicle starting controller through the multifunctional interface.

[0061] As shown in Figure 3 , when the multifunctional interface 15 is currently connected to the auxiliary battery 22, and the state of the charging input interface 13 is not connected to an external power supply, the main control board 12 determines that the current working mode of the energy storage power supply is the auxiliary battery discharging mode, and controls the auxiliary battery to discharge externally through the multifunctional interface and the discharge output interface. Specifically, the control circuit is switched, the on-off control 16 controls the passage to be in the disconnected state, and the auxiliary battery discharges externally through the multifunctional interface 15 and the discharge output interface 14.

[0062] As shown in Figure 4 , when the multifunctional interface 15 is currently connected to the auxiliary battery 22, and the state of the charging input interface 13 is connected to an external power supply, the main control board determines that the current working mode of the energy storage power supply is the auxiliary battery charging mode, and controls the external power supply to charge the auxiliary battery through the charging input interface 13 and the multifunctional interface 15. Specifically, the control circuit is switched, the on-off control 16 controls the passage to be in the disconnected state, and the external power supply charges the auxiliary battery through the charging input interface and the multifunctional interface.

[0063] Referring to Figure 5 , Figure 5As shown in some possible embodiments, when the multifunctional interface 15 is currently connected to the secondary battery 22, and the state of the charging input interface 13 is connected to the external power supply, the main control board determines that the current working mode of the energy storage power supply is the main and secondary battery charging mode. For example, preferably, the external power supply is first controlled to charge the main battery through the charging input interface 13, and after the main battery is fully charged, the line switching is controlled to enable the external power supply to charge the secondary battery through the charging input interface 13 and the multifunctional interface 15.

[0064] Referring to Figure 6 and Figure 7 , Figure 6 and Figure 7 respectively show two working scenarios of the energy storage power supply 10 when the multifunctional interface 15 is not connected to the functional device, and the main control board determines the current working mode of the energy storage power supply as the main battery charging mode or the main battery discharging mode in combination with the state of the charging input interface.

[0065] As shown in Figure 6 , when the multifunctional interface is not currently connected to the functional device, and the state of the charging input interface is connected to the external power supply, the main control board determines that the current working mode of the energy storage power supply is the main battery charging mode, and controls the external power supply to charge the main battery through the charging input interface.

[0066] As shown in Figure 7 , when the multifunctional interface is not currently connected to the functional device, and the state of the charging input interface is not connected to the external power supply, but the discharging output interface 14 is connected to an external device (not shown in the figure), the main control board determines that the current working mode of the energy storage power supply is the main battery discharging mode, and controls the main battery to discharge externally through the discharging output interface 14.

[0067] The identification of the multifunctional interface to the functional device mentioned in the foregoing embodiments of the present application can be physical identification or electrical signal identification.

[0068] In some embodiments, when physical identification is adopted, the multifunctional interface further includes at least two physical switches, each of which corresponds to a functional device. When the multifunctional interface is connected to the current functional device, the physical switch corresponding to the current functional device is triggered, and the main control board identifies the current connected functional device according to the triggered physical switch.

[0069] For example, more than 2 physical switches are added to the multifunctional interface: physical switch 1 and physical switch 2. When the vehicle starting controller is plugged in, only physical switch 1 is turned on, and after being recognized by the main control board, the energy storage power supply is determined as the vehicle starting source, and the vehicle starting controller is outputted with electric energy; when the secondary battery is plugged in, only physical switch 2 is turned on, and after being recognized by the main control board, the multifunctional interface of the energy storage power supply is determined as the secondary battery interface, and then the current secondary battery discharge mode or secondary battery charging mode can be determined in combination with the charging input interface.

[0070] In some embodiments, when the electrical signal mode is used for recognition, the multifunctional interface further comprises a communication component; when the multifunctional interface is connected with the current functional device, the main control board is connected with the functional device through the communication component for recognition of the current connected functional device.

[0071] In some embodiments, the communication connection mode can be a wired connection communication mode.

[0072] In some embodiments, the communication connection mode can be a wireless connection communication mode, such as RF, Bluetooth, and other short-distance wireless communication modes.

[0073] For example, at least one port different from the positive and negative poles can be added to the multifunctional interface for communication between the energy storage power supply and the external functional device, or wireless communication can be used, so as to recognize the type of functional device and take this interface as the corresponding functional port. For example, when the vehicle starting controller is plugged in, the interface is taken as the vehicle starting source after communication with the communication component of the vehicle starting controller; when the secondary battery is plugged in, the interface is taken as the interface of the secondary battery after communication with the communication component of the secondary battery.

[0074] Referring to Figure 8 , Figure 8 Some embodiments of the energy storage power supply 10 are shown, which contain more components and functions. The main difference from Figure 1 includes:

[0075] In some embodiments, the energy storage power supply 10 further comprises a power management system BMS 17, an inverter 18, and an AC output interface 19. The alternating current AC can be generated through the inverter, which can be AC 110V or AC 220V. The inverter is used to convert the electric energy of the main battery into alternating current, and the AC output interface is used to output the alternating current to the external alternating current equipment. The BMS 17 is used to realize the management of the power supply.

[0076] In some embodiments, the energy storage power supply 10 further comprises a key 146 for the user to select and control the functions. Optionally, it further comprises an illumination module (not shown in the figure) and a display module (not shown in the figure).

[0077] In some embodiments, the discharge output interface is further implemented as one or more of the lighting module interface 141, the display module interface 142, the DC output interface 144, the USB output interface 145, and the cigar lighter output interface 143, so as to realize different power consumption functions of the energy storage power supply 10.

[0078] Figure 8 The specific working principle of the embodiments can also refer to the relevant description of the foregoing Figures 1-7 , which will not be repeated here.

[0079] In summary, in the embodiments of the present application, the energy storage power supply only needs to add one multifunctional interface to have multiple practical functions. When different external devices are connected to this interface, it can be automatically identified and set to the corresponding function, such as connecting the automobile starting controller to be used for automobile emergency starting, connecting the auxiliary battery to charge the auxiliary battery or use the auxiliary battery as the power supply of the energy storage product. Thus, the integration of multiple functions is realized, the product components are more simple, and the product design difficulty is greatly reduced. In addition, it is beneficial to reduce the product cost and greatly improve the performance-price ratio of the energy storage product. Moreover, it brings great convenience to the user and improves the user experience.
