[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0024] like Figures 1 to 7 In the embodiment of the energy storage battery box of this utility model shown, the energy storage battery box includes a box body 1, a plurality of partition plates 2 are provided inside the box body 1, and energy storage compartments 3 are formed between adjacent partition plates 2. An opening (not marked in the figure) is provided on the front end of the energy storage compartment 3 of the box body 1, and a control compartment 4 is provided at the rear end of the energy storage compartment 3. A functional hole 5 is provided on the box body 1 at the other end of the control compartment 4. A battery module 6 is provided inside the energy storage compartment 3 and can be pulled out and removed from the opening. A connecting busbar 7 is fixedly connected between the energy storage compartment 3 and the control compartment 4. An elastic connector 8 is provided on the battery module 6 to abut against the connecting busbar 7. The elastic connector 8 is electrically connected to the battery module 6 and the connecting busbar 7.

[0025] Specifically, multiple battery modules 6 are installed into the energy storage compartment 3 through the opening of the housing 1. The elastic connectors 8 on the battery modules 6 abut against the connecting busbar 7, so that the battery and the connecting busbar 7 are connected for charging and discharging, and the multiple battery modules 6 are connected in parallel. The battery management system and charging and discharging control system equipment (existing technology, not within the scope of this application, will not be described here) are installed in the control compartment 4. The partition plate 2 can be a cooling plate for the temperature management of the battery modules 6 (existing technology, not within the scope of this application, will not be described here). When troubleshooting, the battery modules 6 connected in parallel through the connecting busbar 7 can be removed individually without removing the battery box, and the energy storage battery box will not stop working. The elastic connectors 8 ensure the stability of the battery modules 6 and the connecting busbar 7 during operation.

[0026] In one embodiment of this application, preferably, the battery module 6 includes a pull-out box 61 for encapsulating the battery. The pull-out box 61 has snap-fit ​​components 62 fixed to the housing 1 on both sides of one open end. A handle 63 is fixedly connected to the end face of the pull-out box 61 at one open end. An elastic connector 8 is fixedly connected to the other end of the pull-out box 61 to snap the battery module 6 onto the housing 1 after it is installed, so as to prevent it from falling off automatically and loosening.

[0027] In one embodiment of this application, preferably, the elastic connector 8 includes an elastic arc-shaped connecting piece 81. A groove 64, matching the width of the arc-shaped connecting piece 81, is provided on the outer side of the pull-out box 61. The upper end of the arc-shaped connecting piece 81 is fixedly connected to the groove 64 via a conductive connecting post 82. The lower end of the arc-shaped connecting piece 81 abuts against the groove 64 and slides within the groove 64. The arc apex of the arc-shaped connecting piece 81 abuts against the connecting busbar 7. The material and cross-sectional size of the arc-shaped connecting piece 81 are selected according to the magnitude of the charging and discharging current. The arc-shaped connecting piece 81 is connected to the charging and discharging terminals of the battery via the conductive connecting post 82, thus connecting the charging and discharging terminals of the battery to the connecting busbar 7. When the battery module 6 is installed in the energy storage chamber 3, the arc-shaped connecting piece 81 is connected to the connecting busbar 7. When the battery module 6 is removed, it is disconnected from the connecting busbar 7. When abutting against the connecting busbar 7, the lower end of the arc-shaped connecting piece 81 slides freely to generate elasticity, causing the arc apex to press firmly against the connecting busbar 7.

[0028] In one embodiment of this application, preferably, the snap-fit ​​assembly 62 includes a lock body 621 and a lock cylinder 622. The lock cylinder 622 elastically extends and retracts within the lock body 621. The lock body 621 is fixedly connected to the pull-out box 61. One end of the lock cylinder 621 is fixedly connected to a latch 623. The housing 1 has a lock hole 9 for the latch 623 to extend into, for fixing the battery module 6 sent into the energy storage compartment 3.

[0029] In one embodiment of this application, preferably, the other end of the lock cylinder 622 is fixedly connected to a spring 624, and the other end of the spring 624 is fixedly connected to the lock body 621, so as to make the lock cylinder 622 slide elastically within the lock body 621, and the lock cylinder 622 pushes the bolt 623 to extend into or out of the lock hole 9 under the action of the spring 624.

[0030] In one embodiment of this application, preferably, the handle 63 is provided with a telescopic groove (not shown in the figure), and an unlocking button 631 is elastically slidable in the telescopic groove 631. A wedge block 632 is fixedly connected to the unlocking button 631. The lock cylinder 622 is provided with a wedge groove 625 that matches the wedge block 632. The wedge block 632 moves upward to push the lock cylinder 622 to compress the spring 624 and drive the bolt 623 out of the lock hole 9. When the unlocking button 631 is pushed upward, the unlocking button 631 drives the wedge block 632 to compress the wedge groove 625, causing the lock cylinder 622 to compress the spring 624 and drive the bolt 623 to retract into the lock body 621, thereby releasing the engagement between the locking assembly 62 and the housing 1. A reset spring (not marked in the figure) for resetting the unlocking button 631 is connected between the unlocking button 631 and the telescopic groove 631 of the handle 63.

[0031] In one embodiment of this application, preferably, there are two handles 63, both of which cooperate with the snap-fit ​​component 62. When removing the battery module 6, the unlocking buttons 631 on both handles 63 need to be unlocked simultaneously to remove the battery module 6, so as to avoid injury to the operator or damage to the battery module 6 due to misjudging the weight of the battery module 6 during removal.

[0032] In one embodiment of this application, preferably, the side and bottom surfaces of the pull-out box 61 are provided with heat dissipation holes 65 for heat dissipation of the battery inside the pull-out box 61.

[0033] In summary, the energy storage battery box in the above embodiments of this utility model specifically involves fixing the charging and discharging terminals of the battery to the charging and discharging arc-shaped connecting piece 81 on the pull-out box 61 via conductive connecting posts 82. The pull-out box 61 containing the battery is then inserted into the energy storage chamber 3. When pushed into the energy storage chamber 3, the arc-shaped connecting piece 81 abuts against the connecting busbar 7, causing the locking tongue 623 to engage with the lock hole 9. The arc-shaped connecting piece 81 is then pressed tightly against the connecting busbar 7, at which point the battery module 6 is connected. When maintenance or replacement is required, both hands hold the handle 63 and squeeze the unlocking button 631 on the handle 63 to retract the locking tongue 623 into the lock body 621. Both hands pull out the battery module 6, causing the arc-shaped connecting piece 81 to disconnect from the connecting busbar 7. At this point, the battery module 6 ceases its charging and discharging operation. Continuing to pull out the handle 63 allows the battery module 6 to be removed from the box 1. This device makes the battery module 6 detachable by electrically connecting the battery module 6 and the elastic connector 8 on the battery module 6 to the connecting busbar 7. After disassembly, it does not affect the normal operation of other battery modules 6, avoiding the problem of inconvenient disassembly and assembly when the overall weight is large. The disassembly and assembly of individual faulty battery modules 6 does not affect the use of the overall energy storage device, thus improving the efficiency of use.
