[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention, by setting a series connection component between the batteries, allows the side plates at both ends of the fixed plate to rotate.

[0048] The moving drive component 309 includes a sliding box 3091 slidably mounted on a second guide groove 306. A screw 3092 is rotatably mounted inside the second guide groove 306 and is threadedly connected to the sliding box 3091.

A top box 3094 is fixedly mounted on the top of the sliding box 3091, and a moving plate 3095 is movably mounted inside the sliding box 3091. Two locking rods 3096 are symmetrically installed on both sides of the movable plate 3095. The locking rods 3087 engage with the positioning groove 3072 to fix the position of the side plate 3031. After the locking rods 3096 are inserted into the second through groove 3088, they push the pressure plate 3089 to move. Then, the rotation of the rotating sleeve 30811 drives the locking rods 3087 into the movable groove 3084, disengaging the locking rods 3087 from the positioning groove 3072, facilitating the rotation of the side plate 3031.

A rotating plate 3098 is rotatably mounted inside the top box 3094. A rod 3099 is eccentrically mounted at the bottom of the rotating plate 3098 and inserts into the top slot 3097. The top of the rotating plate 3098 is fixedly connected to the output shaft of the rotating motor 30910. The rotating motor 30910 is fixedly mounted at the top of the top box 3094. The rod 3099, eccentrically mounted at the bottom of the rotating plate 3098, inserts into the top slot 3097. The sliding box 3091 is inserted into the top groove 3097 at the top of the movable plate 3095. The rotating plate 3098 is driven to rotate, which can push the movable plate 3095 to one side, so that the two locking rods 3096 on one side are respectively locked into the second through groove 3088 on one side, fixing the sliding box 3091 and the toothed plate 3081. The sliding box 3091 is driven to move, which drives the toothed plate 3081 to move, thereby flipping the side plate 3031. This allows the sliding box 3091 to selectively drive the side plate 3031 on one side to flip, which is convenient for use.

[0049] The inside of the fixing plate 301 and the inside of the side plate 3031 are both provided with wire grooves 310. Wires 311 are installed inside the wire grooves 310, and the two ends of the two wires 311 are respectively inserted into the inside of the two electrical blocks 3035. Conductive plates are installed on the end face of the electrical blocks 3035, and the two ends of the wires 311 are electrically connected to the conductive plates on the two electrical blocks 3035 respectively.

[0050] Working principle: During use, the storage station box 1 is equipped with multiple battery packs 2, and the battery packs 2 include multiple odd-numbered batteries 202 to store electrical energy.

[0051] When power needs to be output, one of the battery pack components 2 is selected to output power. The interfaces 205 at both ends of the frame 201 are connected to the positive and negative terminals of the appliance, respectively. Two adjacent batteries 202 are connected in series through a series connection component 3. The number of series connection components 3 is one more than the number of batteries 202, and the series connection components 3 and batteries 202 are arranged alternately.

[0052] When all batteries 202 need to be used together, the telescopic connectors 303 located at opposite ends on the two series-connected connectors 3 at the control end rotate so that they face upwards. Then, all electromagnets 30310 are energized to generate a repulsive force on the magnetic block 3039, pushing the connector block 3035 to move outwards. The connector blocks 3035 located at both ends contact the two second guide slots 306 at their outward ends, while the other connector blocks 3035 move downwards to contact the corresponding connector post 2022, thus connecting multiple batteries 202 in series, thereby connecting multiple batteries 202 in series between the two first guide slots 305.

[0053] In the downward-facing telescopic contact 303, when the electromagnet 30310 is energized, it generates a repulsive force on the magnetic block 3039, pushing the contact block 3035 downward so that the conductive sheet on the end face of the contact block 3035 contacts the contact post 2022. In the upward-facing telescopic contact 303, when the electromagnet 30310 is energized, it generates a repulsive force on the magnetic block 3039, pushing the contact block 3035 upward so that the conductive sheet on the end face of the contact block 3035 contacts the conductive slider 206.

[0054] When only a few batteries 202 within the frame 201 are needed, select a few batteries 202 in the middle, control the series connection components 3 of the selected batteries 202 located on the side away from each other at both ends, so that the side plates 3031 of the two series connection components 3 on the side away from each other can rotate, and then make the connection blocks 3035 move outwards. The two connection blocks 3035 at the end contact the second guide groove 306, and the other connection blocks 3035 contact the corresponding connection posts 2022.

[0055] The following is the principle of how to control the rotation of the side plate 3031: When the required telescopic electrical connector 303 needs to rotate, the control motor 30910 is activated to drive the rotating plate 3098 to rotate a certain angle. Because the eccentrically mounted insert rod 3099 at the bottom of the rotating plate 3098 is inserted into the top groove 3097 at the top of the moving plate 3095, the rotation of the rotating plate 3098 drives the moving plate 3095 to move laterally. This causes the two locking rods 3096 on one side to respectively engage with the second through groove 3088 on the corresponding sliding plate 3082, simultaneously pushing the pressure plate 3089 to move. This causes the rotating sleeve 30811 to rotate around the fixed shaft 30813, which in turn causes the locking rod 3087 to enter the... Inside the movable groove 3084, it disengages from the positioning groove 3072. Then, the drive motor 3093 is turned on, driving the screw 3092 to rotate, which in turn drives the sliding box 3091 to move along the second guide groove 306, thereby driving the toothed plate 3081 to move together. The toothed plate 3081 meshes with the toothed ring 30311 on the rotating shaft 3032, thereby driving the side plate 3031 to rotate and achieve flipping. After flipping, the rotating plate 3098 is controlled to rotate back. At this time, under the elastic force of the coil spring between the rotating sleeve 30811 and the fixed shaft 30813, the locking rod 3087 moves back and locks into the corresponding positioning groove 3072, fixing the position of the side plate 3031 and ensuring the stability of the power connection.

[0056] Meanwhile, since a battery pack comprehensive tester 204 is installed on the frame 201, and the battery pack comprehensive tester 204 is electrically connected between two conductive sliders 206, the battery pack comprehensive tester 204 can be connected in parallel with a battery pack formed by multiple batteries 202 connected in series. This allows for the monitoring of battery pack voltage, total current, charging and discharging internal resistance, circuit continuity, and static leakage current, ensuring the safety of the energy storage power station. This also allows the controller to adjust the power output accordingly, resulting in a more stable, efficient, and energy-saving current output. The controller is used to control the electronic equipment used in the equipment.
