[0059] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0060] The power connection components of an energy storage device 100 according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0061] like Figures 1-6 As shown, the power connection components of the energy storage device 100 according to an embodiment of the present invention include an electrical connector 30, an electrical coupling component 40, and a plurality of switches.

[0062] Electrical connector 30 and electrical mating component 40 are located at both ends of energy storage device 100 in the first direction. Electrical connector 30 includes a positive terminal 301 and a negative terminal 302. Electrical mating component 40 includes a positive terminal 401 and a negative terminal 402. At least a portion of the positive terminal 301 and the positive terminal of battery body 50 of energy storage device 100, the positive terminal 401 and the positive terminal of battery body 50 of energy storage device 100, the negative terminal 302 and the negative terminal of battery body 50 of energy storage device 100, and the negative terminal 402 and the negative terminal of battery body 50 of energy storage device 100 are connected by a switch.

[0063] Electrical connectors 30 and electrical mating parts 40 of adjacent energy storage devices 100 in the first direction are electrically connected to electrically connect multiple battery bodies 50 together, thereby enabling multiple energy storage devices 100 to jointly output power.

[0064] Specifically, by controlling the opening and closing of different switches, the electrical connection state of adjacent energy storage devices 100 can be changed. In particular, by controlling the opening and closing of different switches, the series and parallel connection relationship of adjacent battery bodies 50 can be changed, thereby changing the total voltage and total current of multiple energy storage devices 100.

[0065] In the prior art, multiple battery cells are electrically connected by wires. When it is necessary to change the relationship between the battery cells, the connection between the wires and the battery cells needs to be changed. This makes it difficult and prone to errors when changing the series or parallel connection of adjacent battery cells. In addition, it is inefficient and costly.

[0066] Furthermore, by making the structures of the multiple energy storage devices 100 identical, it is not necessary to sort the energy storage devices 100 when assembling them together along the first direction, which makes it easier to reduce the assembly difficulty.

[0067] It should be explained here that the positive terminal 301 and the positive terminal of the battery body 50, the positive terminal 401 and the positive terminal of the battery body 50, the negative terminal 302 and the negative terminal of the battery body 50, and the negative terminal 402 and the negative terminal of the battery body 50 can all be connected by a switch, or one or two of them can be connected by a switch, and the rest can be directly connected.

[0068] According to the embodiment of the present invention, the power connection component of the energy storage device 100 can change the series and parallel connection relationship of adjacent battery bodies 50 by controlling the opening and closing of different switches, thereby changing the total voltage and total current of multiple energy storage devices 100. This method of changing the series and parallel connection relationship of adjacent battery bodies 50 is simpler, less prone to errors, and facilitates improved efficiency and reduced costs.

[0069] The power connection components of an energy storage device 100 according to a specific embodiment of the present invention are described below with reference to the accompanying drawings.

[0070] In some specific embodiments of the present invention, such as Figures 1-6 As shown, the power connection components of the energy storage device 100 according to an embodiment of the present invention include an electrical connector 30, an electrical coupling component 40, and a plurality of switches.

[0071] In some embodiments of the present invention, one of the electrical connector 30 and the electrical mating member 40 is a male plug and the other is a female plug, so as to facilitate the electrical connection between the multiple energy storage devices 100 when assembling the multiple energy storage devices 100 together along the first direction, so that the multiple energy storage devices 100 can output current to the outside together.

[0072] In some alternative embodiments of the present invention, the switch is integrated into the electrical connector 30 and / or the electrical mating component 40, which facilitates the reduction of the number of parts and makes it convenient for the switch to be connected to the positive terminal 301, the positive mating terminal 401, the negative terminal 302, and the negative mating terminal 402.

[0073] For example, a switch electrically connected to the positive terminal 301 and the negative terminal 302 is integrated into an electrical connector 30, and a switch electrically connected to the positive terminal 401 and the negative terminal 402 is integrated into an electrical connector 40.

[0074] In some alternative embodiments of the present invention, such as Figure 4As shown, the power connection assembly includes a circuit board 55, and a switch is integrated into the circuit board 55. The circuit board 55 is used to connect to the positive and negative terminals of the battery body 50. The circuit board 55 enables at least a portion of the following connections to the battery body 50: positive terminal 301 and positive terminal 50, positive terminal mating terminal 401 and positive terminal 50, negative terminal 302 and negative terminal 50, and negative terminal mating terminal 402 and negative terminal 50, to be connected via a switch.

[0075] This enables the electrical connection of adjacent energy storage devices 100 to the electrical connection of the electrical connectors 30 and the electrical connection of the electrical connectors 40, so as to connect multiple battery bodies 50 together, thereby enabling multiple energy storage devices 100 to output power together. The circuit board 55 communicates with the control components of the energy storage device 100 to control the opening and closing of the switch, thereby changing the series and parallel connection relationship of adjacent battery bodies 50, and thus changing the total voltage and total current of multiple energy storage devices 100.

[0076] In some embodiments of the present invention, such as Figure 3 As shown, the circuit board 55 is located inside the energy storage device 100 to facilitate the protection of the circuit board 55, and at the same time, to facilitate the reduction of the distance between the circuit board 55 and the battery body 50, thereby facilitating the reduction of wire length and improving the stability of the electrical connection between the circuit board 55 and the battery body 50.

[0077] In some alternative embodiments of the present invention, such as Figure 4 As shown, the circuit board 55 is provided with a first terminal 551 and a second terminal 552. The first terminal 551 and the second terminal 552 are respectively used to electrically connect to the positive and negative terminals of the battery body 50, so as to realize the connection between the circuit board 55 and the battery body 50. Then, the circuit board 55 connects the positive terminal 301 and the positive terminal of the battery body 50, the positive terminal 401 and the positive terminal of the battery body 50, the negative terminal 302 and the negative terminal of the battery body 50, and the negative terminal 402 and the negative terminal of the battery body 50 through a switch.

[0078] In some embodiments of the present invention, the power connection assembly further includes a switch panel located inside and / or outside the energy storage device 100, with the switch integrated into the switch panel.

[0079] The series connection of adjacent battery bodies 50 can be controlled by manually opening and closing the switch, or the switch can be opened and closed automatically by an electrical signal.

[0080] In some embodiments of the present invention, such as Figure 5 , Figure 6As shown, the electrical connector 30 also includes a first grounding terminal 303, and the electrical mating component 40 also includes a second power connection terminal 403. The first grounding terminal 303 and the second power connection terminal 403 of adjacent electrical connectors 30 and electrical mating components 40 are electrically connected to ground the energy storage device 100, thereby improving the safety of the energy storage device 100.

[0081] In some embodiments of the present invention, such as Figure 5 , Figure 6 As shown, the electrical connector 30 includes multiple electrical terminals, which are either positive connection terminals 301 or negative connection terminals 302 depending on whether the electrical terminals are electrically connected to the positive or negative terminal of the battery body 50. The electrical mating component 40 includes multiple electrical terminals, which are either positive mating terminals 401 or negative mating terminals 402 depending on whether the electrical terminals are electrically connected to the positive or negative terminal of the battery body 50.

[0082] The arrangement of the positive terminal 301 and the negative terminal 302 on the electrical connector 30, and the arrangement of the positive terminal 401 and the negative terminal 402 on the electrical connector 40 can be designed according to actual needs, and no further restrictions are imposed here.

[0083] The energy storage module 1000 according to an embodiment of the present invention is described below. The energy storage module 1000 according to an embodiment of the present invention includes a plurality of energy storage devices 100, the plurality of energy storage devices 100 being arranged along a first direction, and each energy storage device 100 including a power connection component of the energy storage device 100 according to the above embodiment of the present invention.

[0084] In some embodiments of the present invention, the energy storage device 100 includes a housing 10, electrical connectors 30 and electrical mating parts 40 located on opposite sidewalls of the housing 10 in a first direction. When multiple energy storage devices 100 are arranged along the first direction, the electrical connectors 30 and electrical mating parts 40 of adjacent energy storage devices 100 are electrically connected to electrically connect multiple battery bodies 50 together, thereby enabling multiple energy storage devices 100 to jointly output power.

[0085] According to an embodiment of the present invention, the energy storage module 1000 can change the series and parallel connection relationship of adjacent battery bodies 50 by controlling the opening and closing of different switches through the power connection component of the energy storage device 100 according to the above embodiment of the present invention, thereby changing the total voltage and total current of multiple energy storage devices 100. This method of changing the series and parallel connection relationship of adjacent battery bodies 50 is simpler, less prone to errors, and facilitates improved efficiency and reduced costs.

[0086] In some embodiments of the present invention, at least one of the positive electrode connection terminal 301 and the negative electrode connection terminal 302 is multiple, and at least one of the positive electrode mating terminal 401 and the negative electrode mating terminal 402 is multiple, so as to form multiple circuits. In this way, when controlling the opening and closing of different switches, some circuits can be turned on and some circuits can be turned off, thereby changing the series and parallel relationship between two adjacent battery bodies 50.

[0087] In some optional embodiments of the present invention, the number of positive electrode connection terminals 301 is the same as the number of negative electrode connection terminals 402, and the number of negative electrode connection terminals 302 is the same as the number of positive electrode connection terminals 401, so that multiple different circuits can be formed. In this way, when controlling the opening and closing of different switches, some circuits can be turned on and some circuits can be turned off, thereby changing the series and parallel relationship between two adjacent battery bodies 50.

[0088] In addition, the number of connection terminals on the electrical connector 30 is the same as the number of mating terminals on the electrical mating component 40, so that the connection terminals of the electrical connector 30 and the mating terminals of the electrical mating component 40 are electrically connected one by one between two adjacent energy storage devices 100, thereby electrically connecting multiple battery bodies 50. This facilitates the improvement of terminal utilization and reduces waste.

[0089] In some specific embodiments of the present invention, such as Figure 7 , Figure 8 As shown, the electrical connector 30 includes a first positive terminal 31, a second positive terminal 32, and a third negative terminal 33. The electrical mating component 40 includes a first negative terminal 41, a second positive terminal 42, and a third negative terminal 43. The first positive terminal 31, the second positive terminal 32, and the third negative terminal 33 of two adjacent energy storage devices 100 are electrically connected to the first negative terminal 41, the second positive terminal 42, and the third negative terminal 43 in a one-to-one correspondence.

[0090] Specifically, the first positive terminal 31 of two adjacent energy storage devices 100 is electrically connected to the first negative terminal 41, the second positive terminal 32 is electrically connected to the second positive terminal 42, and the third negative terminal 33 is electrically connected to the third negative terminal 43.

[0091] In this configuration, the first positive terminal 31 within the same energy storage device 100 is connected to the positive terminal of the battery body 50 via a first switch S1, the first negative terminal 41 is electrically connected to the negative terminal of the battery body 50 via a second switch S2, the second positive terminal 32 within the same energy storage device 100 is electrically connected to the second positive terminal 42, and the second positive terminal 32 and the second positive terminal 42 are electrically connected to the positive terminal of the battery body 50 via a third switch S3, the third negative terminal 33 within the same energy storage device 100 is electrically connected to the third negative terminal 43, and the third negative terminal 33 and the third negative terminal 43 are electrically connected to the negative terminal of the battery body 50 via a fourth switch S4.

[0092] By controlling the first switch S1, the second switch S2, the third switch S3, and the fourth switch S4 to close or open, multiple battery bodies 50 can be connected in series; or multiple battery bodies 50 can be connected in parallel; or multiple battery bodies 50 can be connected in series first and then in parallel.

[0093] In some embodiments, such as Figure 9 As shown, by controlling the first switch S1 and the second switch S2 of each energy storage device 100 to be closed and the other switches to be open, the positive and negative terminals of two adjacent battery bodies 50 are electrically connected through the first positive terminal connection terminal 31 and the first negative terminal mating terminal 41, thereby realizing the series connection of multiple battery bodies 50.

[0094] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0095] The first switch S1 and the second switch S2 of each energy storage device 100 are closed, and the remaining switches are opened, so that the battery bodies 50 of multiple energy storage devices 100 are connected in series.

[0096] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last, respectively. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall series connection.

[0097] In some embodiments, such as Figure 10 As shown, by controlling the third switch S3 and the fourth switch S4 of each energy storage device 100 to be closed and the other switches to be open, the positive terminals of two adjacent battery bodies 50 are electrically connected through the second positive terminal connection 32 and the second positive terminal mating terminal 42, and the negative terminals of two adjacent battery bodies 50 are electrically connected through the third negative terminal connection 33 and the third negative terminal mating terminal 43, thereby realizing the parallel connection of multiple battery bodies 50.

[0098] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0099] The third switch S3 and the fourth switch S4 of each energy storage device 100 are closed, and the remaining switches are opened, so that the battery bodies 50 of multiple energy storage devices 100 are connected in parallel.

[0100] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall parallel connection.

[0101] In some embodiments, by controlling the switching on and off methods of different energy storage devices 100 to be different, multiple battery bodies 50 can be connected in series first and then in parallel.

[0102] In some examples, such as Figure 11 As shown, the energy storage module 1000 includes four energy storage devices 100, which are arranged along a first direction.

[0103] By controlling the switch, the first battery body 50 and the second battery body 50 can be connected in series, the third battery body 50 and the fourth battery body 50 can be connected in series, and then the first battery body 50 and the second battery body 50, the third battery body 50 and the fourth battery body 50 can be connected in parallel.

[0104] Specifically, the first energy storage device 100 and its second and third switches S2 and S3 are closed, while the remaining switches are open; the second and fourth energy storage devices 100 and their first and fourth switches S1 and S4 are closed, while the remaining switches are open.

[0105] The negative terminal of the first battery body 50 and the positive terminal of the second battery body 50 are electrically connected through the first negative terminal mating terminal 41 and the first positive terminal connecting terminal 31, thereby realizing the series connection of the first battery body 50 and the second battery body 50; the negative terminal of the third battery body 50 and the positive terminal of the fourth battery body 50 are electrically connected through the first negative terminal mating terminal 41 and the first positive terminal connecting terminal 31, thereby realizing the series connection of the third battery body 50 and the fourth battery body 50.

[0106] Meanwhile, the positive terminals of the first battery body 50 and the third battery body 50 are electrically connected through adjacent second positive terminal 32 and second positive terminal 42, and the negative terminals of the first battery body 50 and the fourth battery body 50 are electrically connected through adjacent third negative terminal 33 and third negative terminal 43, so as to realize the parallel connection of the first battery body 50 and the second battery body 50, and the third battery body 50 and the fourth battery body 50.

[0107] In some embodiments, the energy storage module 1000 includes a battery system control unit, which has position information of multiple battery bodies 50, and then controls which switches in the energy storage device 100 are turned off and which switches are turned on, so as to flexibly realize the series and parallel relationship of multiple battery bodies 50.

[0108] In some embodiments, such as Figure 7 As shown, the energy storage module 1000 also includes an output component 70, which includes a positive output terminal 71 and a negative output terminal 72. The output component 70 is plugged into and cooperates with the electrical connector 30 at one end of the energy storage module 1000 in the first direction. The positive output terminal 71 is electrically connected to the positive connection terminal 301, and the negative output terminal 72 is electrically connected to the negative connection terminal 302.

[0109] Since the third negative terminal 33 and the third negative terminal 43 of the same energy storage device 100 are electrically connected, and the third negative terminal 43 and the third positive terminal 301 of two adjacent energy storage devices 100 are electrically connected, the negative terminal 72 is electrically connected to the negative terminal of all battery bodies 50 through the fourth switch S4 to form a circuit, and then the output device 70 outputs current to the outside.

[0110] In some examples, the energy storage module 1000 also includes a base 81, on one side of the base 81 in a first direction, a conductive connector 811, a fourth energy storage device 100 located above the base 81, and an electrical connector 40 of the fourth energy storage device 100 cooperating with the conductive connector 811 to connect the first negative terminal 41 and the third negative terminal 43 of the electrical connector 40 of the fourth energy storage device 100. Then, when the second switch S2 of the fourth energy storage device 100 is closed, the conductive connector 811 connects the negative output terminal 72 and the negative terminal of the fourth battery body 50 to form a circuit.

[0111] In some embodiments, the energy storage module 1000 may also include three energy storage devices 100, five energy storage devices 100, six or more energy storage devices 100, and its switching logic is the same as the logic described above, which will not be described in detail here.

[0112] Furthermore, in this embodiment, the first battery unit 50, the second battery unit 50, and the third battery unit 50 can be connected in series and then connected in parallel with the fourth battery unit 50; or the second battery unit 50, the third battery unit 50, and the fourth battery unit 50 can be connected in series and then connected in parallel with the first battery unit 50. The switching control logic is the same as described above and will not be described in detail here.

[0113] In some specific embodiments of the present invention, such as Figure 12 , Figure 13 As shown, the electrical connector 30 also includes a fourth positive terminal 34 and a fifth negative terminal 35, and the electrical mating component 40 also includes a fourth positive mating terminal 44 and a fifth negative mating terminal 45. The fourth positive terminal 34 and the fifth negative terminal 35 of two adjacent energy storage devices 100 are electrically connected to the fourth positive terminal 44 and the fifth negative terminal 45 in a one-to-one correspondence.

[0114] Specifically, the first positive terminal 31 of two adjacent energy storage devices 100 is electrically connected to the first negative terminal 41, the second positive terminal 32 is electrically connected to the second positive terminal 42, the third negative terminal 33 is electrically connected to the third negative terminal 43, the fourth positive terminal 34 is electrically connected to the fourth positive terminal 44, and the fifth negative terminal 35 is electrically connected to the fifth negative terminal 45.

[0115] Specifically, the fourth positive terminal 34 of the energy storage device 100 is electrically connected to the positive terminal of the battery body 50 via the fifth switch S5, the fourth positive terminal 44 is electrically connected to the positive terminal of the battery body 50 via the sixth switch S6, the fifth negative terminal 35 is electrically connected to the negative terminal of the battery body 50 via the seventh switch S7, and the fifth negative terminal 45 is electrically connected to the negative terminal of the battery body 50 via the eighth switch S8.

[0116] By controlling the closing or opening of the first switch S1, the second switch S2, the third switch S3, the fourth switch S4, the fifth switch S5, the sixth switch S6, the seventh switch S7, and the eighth switch S8, multiple battery bodies 50 can be connected in series; or multiple battery bodies 50 can be connected in parallel; or multiple battery bodies 50 can be connected in parallel first and then in series.

[0117] In some embodiments, such as Figure 14 As shown, by controlling the first switch S1 and the second switch S2 of each energy storage device 100 to be closed and the other switches to be open, the positive and negative terminals of two adjacent battery bodies 50 are electrically connected through the first positive terminal connection terminal 31 and the first negative terminal mating terminal 41, thereby realizing the series connection of multiple battery bodies 50.

[0118] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0119] The first switch S1 and the second switch S2 of each energy storage device 100 are closed, and the remaining switches are opened, so that the battery bodies 50 of multiple energy storage devices 100 are connected in series.

[0120] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last, respectively. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall series connection.

[0121] In some embodiments, such as Figure 15 As shown, by controlling the third switch S3 and the fourth switch S4 of each energy storage device 100 to be closed and the other switches to be open, the positive terminals of two adjacent battery bodies 50 are electrically connected through the second positive terminal connection 32 and the second positive terminal mating terminal 42, and the negative terminals of two adjacent battery bodies 50 are electrically connected through the third negative terminal connection 33 and the third negative terminal mating terminal 43, thereby realizing the parallel connection of multiple battery bodies 50.

[0122] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0123] The third switch S3 and the fourth switch S4 of each energy storage device 100 are closed, and the remaining switches are opened, so that the battery bodies 50 of multiple energy storage devices 100 are connected in parallel.

[0124] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall parallel connection.

[0125] In addition, the fifth switch S5 and the sixth switch S6 can be closed simultaneously to replace the closing of the third switch S3; the seventh switch S7 and the eighth switch S8 can be closed simultaneously to replace the closing of the fourth switch S4. That is, the fifth switch S5, the sixth switch S6, the seventh switch S7 and the eighth switch S8 of each energy storage device 100 are closed, and the other switches are open, so that the positive terminals of two adjacent battery bodies 50 are electrically connected through the fourth positive terminal 34 and the fourth positive terminal 44, and the negative terminals of two adjacent battery bodies 50 are electrically connected through the fifth negative terminal 35 and the fifth negative terminal 45, so that multiple battery bodies 50 can be connected in parallel.

[0126] In some embodiments, such as Figure 16 As shown, the energy storage module 1000 includes four energy storage devices 100, which are arranged along a first direction.

[0127] By controlling the switch, the first battery body 50 and the second battery body 50 can be connected in series, the third battery body 50 and the fourth battery body 50 can be connected in series, and then the first battery body 50 and the second battery body 50, the third battery body 50 and the fourth battery body 50 can be connected in parallel, so that multiple battery bodies 50 are first connected in series and then in parallel.

[0128] Specifically, the second switch S2 and the third switch S3 of the first energy storage device 100 and the third energy storage device 100 are closed, and the remaining switches are open; the first switch S1 and the fourth switch S4 of the second energy storage device 100 and the fourth energy storage device 100 are closed, and the remaining switches are open.

[0129] The negative terminal of the first battery body 50 and the positive terminal of the second battery body 50 are electrically connected through the first negative terminal mating terminal 41 and the first positive terminal connecting terminal 31, thereby realizing the series connection of the first battery body 50 and the second battery body 50; the negative terminal of the third battery body 50 and the positive terminal of the fourth battery body 50 are electrically connected through the first negative terminal mating terminal 41 and the first positive terminal connecting terminal 31, thereby realizing the series connection of the third battery body 50 and the fourth battery body 50.

[0130] Meanwhile, the positive terminals of the first battery body 50 and the third battery body 50 are electrically connected through adjacent second positive terminal 32 and second positive terminal 42, and the negative terminals of the first battery body 50 and the fourth battery body 50 are electrically connected through adjacent third negative terminal 33 and third negative terminal 43, so as to realize the parallel connection of the first battery body 50 and the second battery body 50, and the third battery body 50 and the fourth battery body 50.

[0131] Furthermore, the closing of the third switch S3 of the first energy storage device 100 can be replaced by the first switch S1 or the fifth switch S5, or one, two, or all of the first switch S1, the third switch S3, and the fifth switch S5 can be closed simultaneously.

[0132] Following the same logic, other switches in other energy storage devices 100 can also be closed without affecting the relationship between multiple battery bodies 50, which will not be repeated here.

[0133] In some embodiments, such as Figure 17As shown, the first battery body 50, the second battery body 50 and the third battery body 50 can be connected in series, and then connected in parallel with the fourth battery body 50.

[0134] Specifically, the third switch S3 and the second switch S2 of the first energy storage device 100 are closed, and the remaining switches are open; the first switch S1 and the second switch S2 of the second energy storage device 100 are closed, and the remaining switches are open; the first switch S1 and the fourth switch S4 of the third energy storage device 100 are closed, and the remaining switches are open; the third switch S3 and the fourth switch S4 of the fourth energy storage device 100 are closed, and the remaining switches are open.

[0135] Obviously, the closing of the third switch S3 of the first battery body 50 can be replaced by the first switch S1 and the fifth switch S5, or one, two, or all of the first switch S1, the third switch S3, and the fifth switch S5 can be closed simultaneously.

[0136] Following the same logic, other switches in other energy storage devices 100 can also be closed without affecting the relationship between multiple battery bodies 50, which will not be repeated here.

[0137] Extending the above two methods of first connecting multiple batteries in series and then connecting them in parallel, any combination state of series-then-parallel connection between any number of battery bodies 50 can be achieved. For example, the second, third, and fourth battery bodies 50 can be connected in series and then connected in parallel with the first battery body 50, etc., which will not be elaborated on here.

[0138] In some embodiments, such as Figure 18 As shown, the energy storage module 1000 includes four energy storage devices 100, which are arranged along a first direction.

[0139] By controlling the switch, the first battery body 50 and the second battery body 50 can be connected in parallel, the third battery body 50 and the fourth battery body 50 can be connected in parallel, and then the first battery body 50 and the second battery body 50, the third battery body 50 and the fourth battery body 50 can be connected in series, that is, multiple battery bodies 50 are first connected in parallel and then in series.

[0140] Specifically, the first switch S1, the sixth switch S6, and the eighth switch S8 of the first energy storage device 100 and the third energy storage device 100 are closed, while the remaining switches are open. The fifth switch S5, the seventh switch S7, and the second switch S2 of the second energy storage device 100 and the fourth energy storage device 100 are closed, while the remaining switches are open.

[0141] In this way, the positive terminals of the first battery body 50 and the second battery body 50 are electrically connected through the fourth positive terminal 44 and the fourth positive terminal 34, and the negative terminals of the first battery body 50 and the second battery body 50 are electrically connected through the fifth negative terminal 45 and the fifth negative terminal 35, so that the first battery body 50 and the second battery body 50 are connected in parallel.

[0142] The positive terminals of the third battery body 50 and the fourth battery body 50 are electrically connected through the fourth positive terminal 44 and the fourth positive terminal 34, and the negative terminals of the third battery body 50 and the fourth battery body 50 are electrically connected through the fifth negative terminal 45 and the fifth negative terminal 35, so that the third battery body 50 and the fourth battery body 50 are connected in parallel.

[0143] The negative terminals of the second and third battery bodies 50 are electrically connected through the first negative terminal 41 and the first positive terminal 31, so as to connect the second and third battery bodies 50 in series, then connect the first and second battery bodies 50 in parallel, connect the third and fourth battery bodies 50 in parallel, and then connect the first and second battery bodies 50, and the third and fourth battery bodies 50 in series.

[0144] Obviously, for the first energy storage device 100, closing the first switch S1, the sixth switch S6 and the eighth switch S8 or closing the first switch S1, the fifth switch S5, the sixth switch S6 and the eighth switch S8 achieves the same effect. For other switches in other energy storage devices 100, closing them does not affect the relationship between the multiple battery bodies 50, which will not be repeated here.

[0145] In some embodiments, such as Figure 19 As shown, the first battery body 50, the second battery body 50 and the third battery body 50 can be connected in parallel, and then connected in series with the fourth battery body 50.

[0146] Specifically, the first switch S1, the sixth switch S6, and the eighth switch S8 of the first energy storage device 100 are closed, and the other switches are open; the fifth switch S5, the sixth switch S6, the seventh switch S7, and the eighth switch S8 of the second energy storage device 100 are closed, and the other switches are open; the fifth switch S5, the seventh switch S7, and the second switch S2 of the third energy storage device 100 are closed, and the other switches are open; the first switch S1 and the second switch S2 of the fourth energy storage device 100 are closed, and the other switches are open.

[0147] Obviously, the closing of the first switch S1 of the first battery body 50 can be replaced by the third switch S3 or the fifth switch S5, or one, two, or all of the first switch S1, the third switch S3, and the fifth switch S5 can be closed simultaneously.

[0148] Following the same logic, other switches in other energy storage devices 100 can also be closed without affecting the relationship between multiple battery bodies 50, which will not be repeated here.

[0149] Extending the above two methods of first connecting multiple batteries in parallel and then connecting them in series, any combination state of parallel-then-series can be achieved between any number of battery packs. For example, the second battery pack 50, the third battery pack 50 and the fourth battery pack 50 can be connected in parallel and then connected in series with the first battery pack 50, etc., which will not be elaborated on here.

[0150] In some embodiments, the energy storage module 1000 includes a battery system control unit, which has position information of multiple battery bodies 50, and then controls which switches in the energy storage device 100 are turned off and which switches are turned on, so as to flexibly realize the series and parallel relationship of multiple battery bodies 50.

[0151] In some embodiments, the energy storage module 1000 further includes an output component 70, which includes a positive output terminal 71 and a negative output terminal 72. The output component 70 is plugged into and cooperates with the electrical connector 30 at one end of the energy storage module 1000 in a first direction. The positive output terminal 71 is electrically connected to the positive connection terminal 301, and the negative output terminal 72 is electrically connected to the negative connection terminal 302.

[0152] Since the third negative terminal 33 and the third negative terminal 43 of the same energy storage device 100 are electrically connected, and the third negative terminal 43 and the third positive terminal 301 of two adjacent energy storage devices 100 are electrically connected, the negative terminal 72 is electrically connected to the negative terminal of all battery bodies 50 through the fourth switch S4 to form a circuit, and then the output device 70 outputs current to the outside.

[0153] In some examples, the energy storage module 1000 also includes a base 81, on one side of the base 81 in a first direction, a conductive connector 811, a fourth energy storage device 100 located above the base 81, and an electrical connector 40 of the fourth energy storage device 100 cooperating with the conductive connector 811 to connect the first negative terminal 41 and the third negative terminal 43 of the electrical connector 40 of the fourth energy storage device 100. Then, when the second switch S2 of the fourth energy storage device 100 is closed, the conductive connector 811 connects the negative output terminal 72 and the negative terminal of the fourth battery body 50 to form a circuit.

[0154] In some embodiments of the present invention, such as Figure 20 , Figure 21 As shown, the electrical connector 30 includes a first positive terminal 31, a fourth positive terminal 34, and a fifth negative terminal 35. The electrical mating component 40 includes a first negative terminal 41, a fourth positive terminal 44, and a fifth negative terminal 45. The first positive terminal 31, the fourth positive terminal 34, and the fifth negative terminal 35 of two adjacent energy storage devices 100 are electrically connected to the first negative terminal 41, the fourth positive terminal 44, and the fifth negative terminal 45 in a one-to-one correspondence.

[0155] Specifically, the first positive terminal 31 of two adjacent energy storage devices 100 is electrically connected to the first negative terminal 41, the fourth positive terminal 34 is electrically connected to the fourth positive terminal 44, and the fifth negative terminal 35 is electrically connected to the fifth negative terminal 45.

[0159] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0160] The first switch S1 and the second switch S2 of each energy storage device 100 are closed, and the remaining switches are opened, so that the battery bodies 50 of multiple energy storage devices 100 are connected in series.

[0161] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last, respectively. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall series connection.

[0162] In some embodiments, such as Figure 23 As shown, by controlling the fifth switch S5, the sixth switch S6, the seventh switch S7 and the eighth switch S8 of each energy storage device 100 to be closed and the remaining switches to be open, the positive terminals of two adjacent battery bodies 50 are electrically connected through the fourth positive terminal connection terminal 34 and the fourth positive terminal mating terminal 44, and the negative terminals of two adjacent battery bodies 50 are electrically connected through the fifth negative terminal connection terminal 35 and the fifth negative terminal mating terminal 45.

[0163] Specifically, for multiple energy storage devices 100, the multiple energy storage devices 100 are arranged along a first direction, for example, three, four, five, six or more energy storage devices 100.

[0164] The fifth switch S5, the sixth switch S6, the seventh switch S7 and the eighth switch S8 are closed, and the remaining switches are opened, so that the battery bodies 50 of the multiple energy storage devices 100 are connected in parallel.

[0165] In the first direction, the energy storage devices 100 at both ends of the first direction are referred to as the first and the last, respectively. Even if the other switches of the first energy storage device 100 and the last energy storage device 100 are closed, it will not affect the overall parallel connection.

[0166] In some embodiments, such as Figure 24 As shown, by controlling the switch, the first battery body 50 and the second battery body 50 can be connected in parallel, the third battery body 50 and the fourth battery body 50 can be connected in parallel, and then the first battery body 50 and the second battery body 50, the third battery body 50 and the fourth battery body 50 can be connected in series.

[0167] Specifically, the first switch S1, the sixth switch S6, and the eighth switch S8 of the first energy storage device 100 and the third energy storage device 100 are closed, while the remaining switches are open. The fifth switch S5, the seventh switch S7, and the second switch S2 of the second energy storage device 100 and the fourth energy storage device 100 are closed, while the remaining switches are open.

[0168] In this way, the positive terminals of the first battery body 50 and the second battery body 50 are electrically connected through the fourth positive terminal 44 and the fourth positive terminal 34, and the negative terminals of the first battery body 50 and the second battery body 50 are electrically connected through the fifth negative terminal 45 and the fifth negative terminal 35, so that the first battery body 50 and the second battery body 50 are connected in parallel.

[0169] The positive terminals of the third battery body 50 and the fourth battery body 50 are electrically connected through the fourth positive terminal 44 and the fourth positive terminal 34, and the negative terminals of the third battery body 50 and the fourth battery body 50 are electrically connected through the fifth negative terminal 45 and the fifth negative terminal 35, so that the third battery body 50 and the fourth battery body 50 are connected in parallel.

[0170] The negative terminals of the second and third battery bodies 50 are electrically connected through the first negative terminal 41 and the first positive terminal 31, so as to connect the second and third battery bodies 50 in series, then connect the first and second battery bodies 50 in parallel, connect the third and fourth battery bodies 50 in parallel, and then connect the first and second battery bodies 50, and the third and fourth battery bodies 50 in series.

[0171] In some embodiments, the energy storage module 1000 includes a battery system control unit, which has position information of multiple battery bodies 50, and then controls which switches in the energy storage device 100 are turned on and which switches are turned off, so as to flexibly realize the series and parallel relationship of the multiple battery bodies 50.

[0172] In some embodiments, such as Figure 20 As shown, the energy storage module 1000 also includes an output component 70, which includes a positive output terminal 71 and a negative output terminal 72. The output component 70 is plugged into and cooperates with the electrical connector 30 at one end of the energy storage module 1000 in the first direction. The positive output terminal 71 is electrically connected to the positive connection terminal 301, and the negative output terminal 72 is electrically connected to the negative connection terminal 302.

[0173] The electrical connector 30 also includes a functional connection end 38, and the electrical mating part 40 includes a functional mating end 48. The functional connection end 38 and the functional mating end 48 of the same energy storage device 100 are electrically connected, and the functional connection end 38 and the functional mating end 48 of two adjacent energy storage devices 100 are electrically connected.

[0174] The energy storage module 1000 also includes a base 81. The base 81 has a conductive connector 811 on one side in the first direction. The fourth energy storage device 100 is located above the base 81, and the electrical connector 40 of the fourth energy storage device 100 cooperates with the conductive connector 811 to connect the first negative terminal 41 and the functional terminal 48 of the electrical connector 40 of the fourth energy storage device 100, and to connect the fifth negative terminal 45 and the functional terminal 48 of the electrical connector 40 of the fourth energy storage device 100. When the second switch S2 or the eighth switch S8 of the fourth energy storage device 100 is closed, the conductive connector 811 connects the negative output terminal 72 and the negative terminal of the fourth battery body 50 to form a circuit.

[0175] In some embodiments of the present invention, such as Figure 7 , Figure 8 As shown, the energy storage module 1000 also includes an output component 70, which includes a positive output terminal 71 and a negative output terminal 72. The output component 70 is plugged into and cooperates with the electrical connector 30 located at one end of the energy storage module 1000 in the first direction.

The functional mating terminal 48 of the electrical mating component 40 at the other end of the first direction of the energy storage module 1000 is electrically connected to the positive mating terminal 401 and / or the negative mating terminal 402. In this way, when the positive mating terminal 401 and / or the negative mating terminal 402 of the energy storage module 1000 at the end in the first direction are electrically connected to the battery body 50, the current can reach the output component 70 through the functional mating terminal 48 and the functional connection terminal 38, and then output the current outward through the output component 70.

[0178] Whether the positive terminal 401 and / or negative terminal 402 of the energy storage module 1000 at the first direction end are electrically connected to the battery body 50 depends on the opening and closing of the switch, and no further restrictions are imposed here.

[0179] In some embodiments, the functional connection terminal 38 of the electrical connector 30 located at one end of the energy storage module 1000 in the first direction is electrically connected to the negative output terminal 72, and the negative engagement terminal 402 of the electrical engagement component 40 located at the other end of the energy storage module 1000 in the first direction is electrically connected to the functional engagement terminal 48. When the battery body 50 located at the other end of the energy storage module 1000 in the first direction is connected in series with the previous battery body 50, the electrical connection of the negative engagement terminal 402, the functional engagement terminal 48, and the functional connection terminal 38 forms a circuit, and then outputs current to the outside through the output component 70.

[0180] The functional connection terminal 38 is integrated on the electrical connector 30, and the functional mating terminal 48 is integrated on the electrical mating terminal 40, which makes it easier to reduce the number of wiring connections. In this way, after multiple energy storage devices 100 are assembled along the first direction, the negative output terminal 72 can be connected to the negative mating terminal 402 of the electrical mating terminal 40 at the other end of the first direction of the energy storage module 1000, which makes it easier to reduce the difficulty of operation.

[0181] In some embodiments, the energy storage module 1000 further includes a base 81, on one side of the base 81 in a first direction, a conductive connector 811 is provided, and a plurality of energy storage devices 100 are located above the base 81 in the first direction. The electrical coupling member 40 at the other end of the energy storage module 1000 in the first direction cooperates with the conductive connector 811 to connect the negative terminal 402 and the functional terminal 48 of the electrical coupling member 40 using the conductive connector 811, so that the negative terminal of the battery body 50 located at the other end of the energy storage module 1000 in the first direction is electrically connected to the functional terminal 48 through the conductive connector 811, and then electrically connected to the negative terminal 72.

[0182] In some optional embodiments of the present invention, one of the electrical connector 30 and the electrical mating member 40 is a male plug and the other is a female plug, so as to facilitate the electrical connection between the multiple energy storage devices 100 when assembling the multiple energy storage devices 100 together along the first direction, so that the multiple energy storage devices 100 can output current to the outside together.

[0183] In some embodiments, one of the output component 70 and the electrical connector 30 is a male plug and the other is a female plug, so as to facilitate the electrical mating of the output component 70 and the electrical connector 30, so that the positive output terminal 71 is electrically connected to the positive connection terminal 301 and the negative output terminal 72 is electrically connected to the negative connection terminal 302.

[0184] Other configurations and operations of the energy storage module 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0186] According to the embodiments of the present invention, by utilizing the energy storage module 1000 of the present invention, the series and parallel relationships of adjacent battery bodies 50 can be changed by controlling the opening and closing of different switches, thereby changing the total voltage and total current of multiple energy storage devices 100. This method of changing the series and parallel relationships of adjacent battery bodies 50 is simpler, less prone to errors, and facilitates improved efficiency and reduced costs.
