Figure 3 As shown in , each battery pack 100 is provided with an electrical connector 10, and through the electrical connector 10, the adjacent two battery packs 100 can be connected in series after being stacked.

[0064] Here it should be pointed out that although Figures 1-2 the number of battery packs 100 in the energy storage system 1000 shown in is three, this does not mean that the number of battery packs 100 can only be three, but the number can be selected according to needs, but at least two. For example, the number of battery packs 100 is three, four or more than four.

[0065] In order to facilitate understanding of how the adjacent two battery packs 100 are connected in series through the electrical connector 10, it is necessary to first understand the structure of the electrical connector 10 in each battery pack 100. First, the structure of the electrical connector 10 in each battery pack 100 is described as follows:

When the conductive switch group 24 is in the first position, the first conductive member 22 and the second conductive member 23 are conductively connected through the conductive switch group 24, that is Figure 5 as shown in FIG. 2, and when the conductive switch group 24 is moved to the second position under the action of an external force, as shown in Figure 6 and Figure 7 , the conductive switch group 24 is separated from the first conductive member 22 and the second conductive member 23 and is in a disconnected state, and the first conductive member 22 and the second conductive member 23 cannot be conductively connected through the conductive switch group 24.

When the female socket module 2 of one battery pack 100 is separated from the male plug module 4 of another battery pack 100 along the first direction X, as shown, Figure 5 the conductive switch group 24 will return to the original position, so that the first conductive piece 22 and the second conductive piece 23 in the battery pack 100 are in conductive communication through the conductive switch group 24.

Each first elastic element 243 has its two ends connected to the conductive switch element 241 and the second mounting portion 213, respectively. The first conductive element 22 and the second conductive element 23 are both mounted on the limiting bracket 212 and electrically connected to the conductive switch element 241. The push rod 242 is movably disposed on the limiting bracket 212, with one end abutting against the conductive switch element 241 and the other end penetrating through the limiting bracket 212. In this embodiment, there are three elastic elements, all of which are sleeved on the conductive switch element 241. The conductive switch element 241 is located within the first space 2d and extends along the first opening 2f to the third opening 2h in the second direction Y. The push rod 242 passes through the second opening 2g and the second insertion hole 2b.

[0085] When the female socket module 2 and the male plug module 4 are inserted into each other along the first direction X, the first switch support column 44 drives the push rod 242 to move, thereby pushing the conductive switch element 241 to move, so that the first conductive element 22 and the second conductive element 23 are electrically separated. That is, the conductive switch element 241 leaves the initial conductive connection position, so that the first conductive element 22 and the second conductive element 23 are in the disconnected state.

[0086] In some embodiments, such as Figure 9As shown, the conductive switch piece 241 includes a conductive plate 2411 and at least one guide column 2412 disposed on the conductive plate 2411. Each first elastic piece 243 is sleeved on a guide column 2412. One end of each first elastic piece 243 is connected to the conductive plate 2411 and the other end is connected to the second mounting portion 213. The conductive plate 2411 abuts against the first conductive piece 22 and the second conductive piece 23, respectively. When the push rod 242 pushes the conductive plate 2411 to move and press the first elastic piece 243, the conductive plate 2411 moves away from the first conductive piece 22 and the second conductive piece 23, so that the first conductive piece 22 and the second conductive piece 23 are disconnected. That is, the push rod 242 compresses the first elastic piece 243 to obtain a moving space under the action of an external force, so that the conductive plate 2411 moves away from the conductive communication position, so that the first conductive piece 22 and the second conductive piece 23 are in a disconnected state. In this embodiment, the number of guide columns 2412 is three, and each guide column 2412 is inserted into an avoiding opening 2k. Under the limiting of the avoiding opening 2k, the directional movement of the guide column 2412 is constrained to guide the movement of the conductive plate 2411 between the conductive communication position and the disconnected position.

[0087] In some embodiments, as Figure 5 With Figure 9 As shown, the male plug module 4 is provided with a second switch support column 45. The female socket module 2 further includes a micro switch 25 and a sliding assembly 26. The micro switch 25 is disposed on the female seat body 21 and is used to be electrically connected with the main control board in the battery pack 100. The sliding assembly 26 is disposed on the female seat body 21. In this embodiment, the micro switch 25 is installed in the mounting groove 2i.

[0088] When the female socket module 2 and the male plug module 4 are plugged in along the first direction X, the second switch support column 45 is used to touch the sliding assembly 26 to drive the sliding assembly 26 to move, so that the sliding assembly 26 touches the micro switch 25 to open after moving a preset distance, so that the main control board 60 closes the current output. When the female socket module 2 and the male plug module 4 are separated along the first direction X, the second switch support column 45 moves away from the sliding assembly 26, and the sliding assembly 26 releases the micro switch 25, so that the main control board closes the current output.

[0089] In some embodiments, as Figure 5 With Figure 9As shown, the sliding assembly 26 comprises a sliding rod 261, a pressing member 262 and a second elastic member 263, the sliding rod 261 is arranged on the female socket body 21 and moves with the conductive switch assembly 24, the pressing member 262 is fixedly arranged on the sliding rod 261, and the second elastic member 263 is sleeved on the sliding rod 261 and arranged at one end of the mounting groove 2i. In this embodiment, the sliding rod 261 is arranged in the sliding hole 2j, when the female socket module 2 and the male plug module 4 are plugged in the first direction X, the second switch supporting column 45 abuts against the sliding rod 261 to drive the pressing member 262 to move a preset distance, and the second elastic member 263 is compressed by the sliding rod 261 to obtain a moving space, and the pressing member 262 touches the micro switch 25 to be turned on.

[0090] In some embodiments, the sliding rod 261 and the pressing member 262 are integrally formed, and the pressing member 262 is located on one side of the sliding rod 261, so that the pressing member 262 can move synchronously when the sliding rod 261 moves, thereby realizing the pressing of the micro switch 25.

[0091] In some embodiments, as Figure 8 With Figure 10 As shown, the micro switch 25 comprises a switch body 251, a first pin 252, a second pin 253 and a key module 254 movably connected to the switch body 251, the switch body 251 is fixed in the mounting groove 2i of the second mounting portion 213 of the female socket body 21, the first pin 252 and the second pin 253 are arranged on the switch body 251, and the first pin 252 and the second pin 253 are used for electrically connecting the main control board 60 of the battery pack 100. The key module 254 can move relative to the switch body 251 to turn on or turn off the first pin 252 and the second pin 252.

[0092] It is worth noting that, before the female socket module 2 on one battery pack 100 is used to be plugged in the first direction X with the male plug module 4 on another battery pack 100, since the first pin 252 and the second pin 253 are electrically connected to the main control board of the battery pack 100, the female socket module 2 is electrified. When the sliding rod 261 moves a preset distance in the first direction X, the pressing member 262 is driven to move to press the key module 254, and the key module 254 can turn on the first pin 252 and the second pin 252; when the first pin 252 and the second pin 252 are turned on, the first conductive part 22 and the second conductive part 23 have not been respectively connected to the first conductive joint 42 and the second conductive joint 43 to realize the plug-in contact connection, that is, at this time, the female socket module 2 and the male plug module 4 realize successful plug-in, at this time, the main control board of the battery pack 100 receives the plug-in signal, which means that the female socket module 2 and the male plug module 4 are about to be plugged in, and then the main control board turns off the current output, so that the female socket module 2 is not electrified, thereby avoiding the phenomenon of striking fire caused by the instantaneous voltage / current impact of the female socket module 2 and the male plug module 4 when the battery packs are stacked.

[0093] In some embodiments, as shown in Figure 10 The key module 254 includes a metal sheet (not shown) and a key plate 2541, the metal sheet is movably arranged on the switch body 251 and fixedly connected with the key plate 2541, and the key plate 2541 is arranged at one end of the female socket module 2 for docking the male plug module 4 and movably connected with the switch body 251. When the female socket module 2 is inserted into the male plug module 4, the male plug module 4 presses the key plate 2541 to move, and the key plate 2541 is used to drive the metal sheet to contact the first pin 252 and the second pin 253, so that the first pin 252 and the second pin 253 are conducted.

[0094] In some embodiments, as shown in Figure 10 The key plate 2541 is elastically connected to the switch body 251, and when the male plug module 4 is inserted into the female socket module 2 and touches the key plate 2541, the key plate 2541 elastically deforms to generate an elastic force. When the male plug module 4 is pulled out of the female socket module 2, the key plate 2541 gradually recovers to the off position under the action of the elastic force.

[0095] In some embodiments, as shown in Figure 5 The female socket module 2 further includes a first communication interface 27 arranged on the female seat body 21 and used for electrical connection with the main control board in the battery pack 100, and the male plug module 4 further includes a second communication interface 46 arranged on the male seat body 41 and used for electrical connection with the main control board in the battery pack 100. When the female socket module 2 and the male plug module 4 are inserted in the first direction X, the first communication interface 27 of one battery pack 100 and the second communication interface 46 of another battery pack 100 are inserted. In this way, communication connection can be established between the two adjacent battery packs 100 after stacking, so as to facilitate the management of charging and discharging between the stacked multiple battery packs 100.

[0096] In order to facilitate understanding of the process of inserting the female socket module 2 and the male plug module 4, please refer to Figures 11a-11d As shown in Figure 11a The schematic diagram of the female socket module 2 and the male plug module 4 before being inserted is shown in the figure, at this time, the first conductive part 22 and the first conductive connector 42 have a spacing, the second conductive part 23 and the second conductive connector 43 also have a spacing, the micro switch 25 has not been pressed, and the first communication interface 27 and the second communication interface 46 have a spacing.

[0097] As shown in Figure 11b Figure 11b ​The diagram shows the female socket module 2 and the male plug module 4 approaching each other but not yet interlocked. At this time, the female socket module 2 is pressed down as a whole, and the second switch support column 45 begins to press against the slide bar 261. At this time, the pressing member 262 begins to push the micro switch 25. After the slide bar 261 has moved the preset distance, the micro switch 25 is closed by force. That is, at this time, the first pin 252 of the micro switch 25 is connected, and the micro switch 25 releases the interlocking signal to the main control board of the battery pack 100, indicating that there is a stacking interlocking between the battery packs 100. The interlocking signal is transmitted to the main control board, and the main control board cuts off the current output. At this time, the female socket module 2 is not powered to prevent arcing problems during subsequent interlocking.

[0098] like Figure 11c As shown, Figure 11c The diagram shows a simplified illustration of the female socket module 2 and the male plug module 4 starting to be inserted. At this time, the first switch support column 44 begins to contact the push rod 242, and the conductive switch component 241 begins to operate. The first conductive component 22 and the first conductive connector 42, and the second conductive component 23 and the second conductive connector 43 are about to make contact.

[0099] like Figure 11d As shown, Figure 11d The diagram shows a simplified illustration of the female socket module 2 and the male plug module 4 fully interlocked. The first switch support column 44 moves a set distance against the push rod 242 to open the conductive switch 241. At this time, the first conductive element 22 and the second conductive element 23 are disconnected and in an open state. The first conductive element 22 is conductively connected to the first conductive connector 42, and the second conductive element 23 is conductively connected to the second conductive connector 43.

[0100] The electric connector 10 with the above structure is used, the female socket module 2 and the male plug module 4 of the electric connector 10 are respectively located at two ends of the battery pack 100 along the first direction X, so that when a plurality of battery packs 100 are stacked along the first direction X, the female socket module 2 and the male plug module 4 can be docked with each other without using a cable, which is beneficial to simplify the connection mode and improve the connection efficiency. When the female socket module 2 and the male plug module 4 are docked, the first switch support column 44 pushes against the push rod 242 to move, so that the conductive switch piece 241 moves a preset distance under the action of the push rod 242, so that the first conductive piece 22 and the second conductive piece 23 are switched from the conductive communication state to the disconnected state, and the first conductive connector 42 is in conductive connection with the first conductive piece 22, and the second conductive connector 43 is in conductive connection with the second conductive piece 23, so as to realize series connection between adjacent two battery packs 100. At the same time, the second switch support column 45 pushes the sliding rod 261 against the second elastic piece 263, so that the sliding rod 261 can drive the pressing piece 262 to move a preset distance, so that the pressing piece 262 actuates the micro switch 25 to open to control the main control board to close the current output, so as to avoid the problem of sparking when plugging.

[0101] In some embodiments, as shown in Figures 12-14 In addition to the electric connector 10 in the above embodiments, the battery pack 100 also includes a shell 20, a battery module 30, a third conductive piece 40 and a fourth conductive piece 50, and the battery module 30, the third conductive piece 40 and the fourth conductive piece 50 are all located in the shell 20.

[0102] As shown in Figure 14 The third conductive piece 40 is arranged in the shell 20, and the first conductive piece 22 is connected with the first electrode of the battery module 30 through the third conductive piece 40. The fourth conductive piece 50 is arranged in the shell 20, and the second conductive piece 23 is connected through the fourth conductive piece 50 and the second conductive connector 43.

[0103] As shown in Figure 14 The shell 20 is provided with a first mounting opening 20a and a second mounting opening 20b distributed along the first direction X, the female socket module 2 of the electric connector 10 is arranged in the first mounting opening 20a, the male plug module 4 of the electric connector 10 is arranged in the second mounting opening 20b, at least part of the first conductive piece 22 and the second conductive piece 23 are exposed outside the shell 20 through the first mounting opening 20a, and at least part of the first conductive connector 42, the second conductive connector 43 and the first switch support column 44 are exposed outside the shell 20 through the second mounting opening 20b. In this way, when a plurality of batteries are stacked for use, the male plug module 4 of one battery pack 100 is plugged with the female socket module 2 through the first mounting opening 20a of another battery pack 100.

[0104] In some embodiments, as shown in Figure 14As shown, the shell 20 comprises an upper cover 201, a lower cover 202, a front cover 203, a rear cover 204, a left cover 205 and a right cover 206 connected together, the upper cover 201 and the lower cover 202 are arranged oppositely along the first direction X, the left cover 205 and the right cover 206 are arranged oppositely along the second direction Y, and the front cover 203 and the rear cover 204 are arranged oppositely along the third direction, so as to form a space for accommodating the battery module 30. The upper cover 201 is provided with a first mounting hole 20a, and the lower cover 202 is provided with a second mounting hole 20b.

[0105] It can be understood that the connection mode between the upper cover 201, the lower cover 202, the front cover 203, the rear cover 204, the left cover 205 and the right cover 206 can be through clamping, gluing, bolt connection and the like, as long as the mutual connection and fixation can be realized.

[0106] In some embodiments, as shown in Figures 13-14 The shell 20 further comprises two detachable handles 207 connected to the upper cover 201, and the two handles 207 are respectively arranged at the two side ends of the upper cover 201. In this embodiment, in order to facilitate the carrying of the battery pack 100 and avoid the installation position of the handle 207 interfering with the male plug module 4, the two handles 207 are arranged at the two side ends of the upper cover 201 along the third direction.

[0107] In some embodiments, as shown in Figures 14-15 The battery module 30 comprises a battery pack 301, two fixing plates 302 and a supporting plate 303. The battery pack 301 comprises a plurality of stacked batteries connected in series with each other. The two fixing plates 302 are respectively arranged at the two sides of the battery pack 301. The supporting plate 303 is arranged at one side of the battery and connected with the two fixing plates 302 respectively. In this way, under the action of the two fixing plates 302 and the supporting plate 303, the battery pack 301 can be fixed and strengthened, the scattered situation of the binding belts 304 for fixing the plurality of batteries of the battery pack 301 can be avoided when the binding belts 304 are disconnected, and the assembly personnel can also move the whole battery pack 301 conveniently.

[0108] The battery module 30 of the battery pack 100 can be a single battery cell or a plurality of series or parallel battery cells. The positive electrode of the battery pack 100 is the positive electrode of the battery module 30, and the negative electrode of the battery pack 100 is the negative electrode of the battery module 30.

[0109] In some embodiments, as shown in Figure 16As shown, the battery module 30 further comprises a busbar 305 and a plurality of collecting pieces 306, the busbar 305 is arranged at the side where the tabs of the plurality of batteries are located, and each collecting piece 306 is connected with the electrode of one battery, so that the collecting piece 306 transmits the collected information (such as the voltage of the battery) to the busbar 305.

[0110] In some embodiments, as Figure 16 As shown, the battery pack 100 further comprises a master control board 60, which is arranged at the end of the battery module 30 close to the male plug module 4, and the second electrode of the battery module 30 and the second conductive connector 43 are both connected to the master control board 60. In this embodiment, the master control board 60 is arranged on the support plate 303, and the master control board 60 is electrically connected to the busbar 305, so that the master control board 60 controls the plurality of batteries of the battery module 301 through the busbar 305. At the same time, the micro switch 25 is connected to the master control board 60 through the wire harness, so that when the micro switch 25 is in the open or closed state, the master control board 60 controls whether the internal circuit is cut off.

[0111] It should be noted that, as mentioned above, when the two battery packs 100 are inserted and stacked, during the insertion process, when the second switch support column 45 pushes the sliding rod 261 to press the second elastic member 263, the sliding rod 261 can drive the pressing member 262 to move a predetermined distance, so that the pressing member 262 triggers the micro switch 25 to open, and the micro switch 25 sends an insertion signal to the master control board 60, and the master control board 60 temporarily closes the current output, that is, the current path between the male plug module 4 and the female socket module 2 of the two battery packs 100 being inserted is closed, so as to avoid the occurrence of electric arc during the insertion process.

[0112] Next, taking the number of battery packs 100 of the energy storage system 1000 as three as an example, how the plurality of battery packs 100 are connected in series will be described, as Figure 3 and Figure 17 For convenience of distinction, the three battery packs 100 are respectively named as the first battery pack 100a, the second battery pack 100b and the third battery pack 100c, and the first electrode of the battery pack 100 is defined as the positive electrode M of the battery pack 100, and the second electrode of the battery pack 100 is defined as the negative electrode N of the battery pack 100.

[0113] Among them, the female socket module 2 of the first battery pack 100a located at the bottom is not affected by the male plug module 4 of another battery pack 100, at this time, the conductive switch group 24 of the female socket module 2 of the first battery pack 100a is in the initial position, that is, the conductive switch piece 241 of the female socket module 2 of the first battery pack 100a is always in conductive communication with the first conductive piece 22 and the second conductive piece 23 of the first battery pack 100a.

[0114] When the female socket module 2 of the second battery pack 100b is connected with the male plug module 4 of the first battery pack 100a, the conductive switch piece 241 of the second battery pack 100b is pushed by the first switch support column 44 of the male plug module 4 of the first battery pack 100a to move the push rod 242, so that the conductive switch piece 241 of the second battery pack 100b moves to the disconnected position, so that the first conductive piece 22 and the second conductive piece 23 of the second battery pack 100b will be disconnected.

[0115] Through the action of the three electric connectors 10 on the three battery packs 100, the three battery packs 100 are connected in series, and the total negative electrode of the energy storage system 1000 formed after stacking is the negative electrode N of the uppermost third battery pack 100c, that is, the total negative electrode of the energy storage system 1000 is at the uppermost position. Moreover, the conductive switch piece 241 of the female socket module 2 on the lowermost first battery pack 100a after stacking is not lifted by the structure of the male plug module 4; if there is no designed fourth conductive piece 50, the total positive electrode of the energy storage system 1000 formed after stacking is at the lowermost first battery pack 100a, that is, when there is no fourth conductive piece 50, the total positive electrode of the energy storage system 1000 is the first conductive piece 22 or the second conductive piece 23 of the electric connector 10 of the first battery pack 100a, that is, the total positive electrode of the energy storage system 1000 is at the lowermost position, which inevitably leads to the inconvenience of subsequent wiring, that is, when the energy storage system 1000 needs to be connected with other electrical equipment, the user needs to wire at the total positive electrode at the lowermost position.

[0116] As shown in Figure 3 In the embodiment of the present application, the second conductive piece 23 electrically connects the fourth conductive piece 50 and the second conductive joint 43, so that when the plurality of battery packs 100 are stacked, the total positive electrode of the energy storage system 1000 is transferred to the uppermost position through the switching action of the plurality of fourth conductive pieces 50, so that the total positive electrode of the energy storage system 1000 after stacking is the positive electrode M of the uppermost third battery pack 100c, and the total negative electrode of the energy storage system 1000 after stacking is the negative electrode N of the uppermost third battery pack 100c, so as to facilitate subsequent wiring of the user. When the user uses the energy storage system 1000 to connect with other electrical equipment, only the uppermost wiring is needed.

[0117] In some embodiments, as shown in Figure 17As shown, the energy storage system 1000 further comprises an energy storage host 200 located on top of the at least two battery packs 100 distributed along the first direction X. Among them, the energy storage host 200 is provided with a circuit board 210, the circuit board 210 is connected through the third conductive part 40 of the battery pack 100 located at the top position and the first electrode of the battery pack 100 at the top, and the circuit board 210 is also connected with the second electrode of the battery pack 100 at the top, so that the battery pack 100 arranged in a stack can be controlled by the circuit board 210 of the energy storage host 200. Among them, the energy storage host 200 can be a battery pack 100 or other control equipment.

[0118] The energy storage system 1000 adopted by the embodiment of the present application can directly realize the series connection between the adjacent two battery packs 100 by plugging the female socket module 2 of one of the two adjacent battery packs 100 and the male plug module 4 of the other battery pack 100, which is convenient for the user to operate without the need of cables, and when it is needed to disconnect the series connection of multiple battery packs 100, only the female socket module 2 and the male plug module 4 of the adjacent battery packs 100 need to be separated, which is relatively convenient and fast to operate.

[0119] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
