The energy storage battery module has efficient energy storage capabilities. By connecting multiple battery cells together, larger capacity energy storage can be achieved to meet the needs of different scenarios. For example, electric vehicles require large-capacity batteries to provide long-lasting power support, while home photovoltaic systems require stable power storage to cope with the imbalance of energy supply and demand during the day and night.

Modern energy storage battery modules are usually equipped with multiple safety protection systems, which can effectively prevent the occurrence of safety problems such as overcharging, over-discharging, and short circuit. Energy storage battery modules are flexible and scalable. Since multiple battery cells can be flexibly combined, the capacity and power of the energy storage battery module can be expanded or reduced according to demand. This means that users can choose battery modules of appropriate capacity according to actual conditions to achieve efficient use of energy and flexible configuration.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example 1: Please refer to Figure 1 - Figure 5 A modular energy storage battery module of the present embodiment includes a first battery module 1 and a second battery module 2. A plug connector 3 is movably connected to one side of the first battery module 1, a plug slot 4 is provided to one side of the second battery module 2, the plug connector 3 is plug-connected to the inside of the plug slot 4, a groove 5 is processed to one side of the first battery module 1, a rotating shaft 6 is fixedly connected to the top of the other end of the plug connector 3, the top of the rotating shaft 6 is rotatably connected to the top inner wall of the groove 5, and one end of the plug connector 3 is rotatably connected to the inside of the groove 5;

[0024] The two energy storage battery modules are respectively configured as a first battery module 1 and a second battery module 2. Since a plug connector 3 is provided inside one side of the energy storage battery module and a plug slot 4 is provided on the other side, the positive and negative electrodes of the two energy storage batteries are connected by plugging the plug connector 3 into the plug slot 4, thereby facilitating the combination of energy storage battery modules of the same size in series in pairs, and the operation is convenient and quick.

[0025] Secondly, when a certain energy storage battery module is not in use, the plug connector 3 is rotated so that the plug connector 3 rotates around the rotating shaft 6, and the rotating shaft 6 rotates around the top inner wall of the groove 5, so that the plug connector 3 is stored inside the groove 5, thereby preventing the plug connector 3 from being located outside the groove 5, causing damage and leading to safety hazards;

[0026] In some examples, one end of the first battery module 1 is rotatably connected to a clamping block 13, one end of the second battery module 2 is fixedly connected to a limiting block 14, and one end of the clamping block 13 is clamped and connected inside the limiting block 14;

[0027] Among them, since the plug connector 3 is inserted into the inside of the plug slot 4, the up and down movement of the first battery module 1 and the second battery module 2 will be restricted. When the first battery module 1 and the second battery module 2 are connected in series, one end of the two card blocks 13 is rotated so that one end of the two card blocks 13 is respectively inserted into the inside of the limit block 14, thereby restricting the forward and backward movement of the first battery module 1 and the second battery module 2, and preventing the plug connector 3 and the plug slot 4 from being out of contact during the connection process of the first battery module 1 and the second battery module 2, resulting in poor contact between the first battery module 1 and the second battery module 2;

[0028] Further, the outside of the groove 5 is processed with a first slide groove 7, the inside of the first slide groove 7 is slidably connected with a first insulating baffle 8, and one end of the first insulating baffle 8 is externally fixedly connected with a first pull block 9. When the plug connector 3 needs to be used, the first pull block 9 is pulled to make the first pull block 9 drive the first insulating baffle 8 to move, and the first insulating baffle 8 will move along the inside of the first slide groove 7, thereby opening the inside of the groove 5, making it convenient to rotate the plug connector 3. By setting the first insulating baffle 8, the first insulating baffle 8 can protect the plug connector 3 inside the groove 5;

[0029] Further, the plug slot 4 is processed with a second slide slot 10 on the outside, and the second slide slot 10 is slidably connected to the inside of the second insulating baffle 11, and one end of the second insulating baffle 11 is externally fixedly connected to a second pull block 12. When the plug connector 3 needs to be plugged into the inside of the plug slot 4, the second pull block 12 is pulled to make the second pull block 12 drive the second insulating baffle 11 to move, and the second insulating baffle 11 will move along the inside of the second slide slot 10, thereby opening the inside of the plug slot 4, making it convenient for the plug connector 3 to be plugged into the inside of the plug slot 4. By setting the second insulating baffle 11, the second insulating baffle 11 can protect the inside of the plug slot 4;

[0030] Furthermore, one end of the first battery module 1 is fixedly connected to a fixed block 15, and one end of the clamping block 13 is rotatably connected to the inside of the fixed block 15. When the energy storage battery module is not in use, one end of the clamping block 13 will be located inside the fixed block 15 and fixed. When the first battery module 1 and the second battery module 2 are connected, one end of the rotating clamping block 13 will be engaged with the inside of the limit block 14, thereby fixing the first battery module 1 and the second battery module 2.

[0031] Working principle: by plugging the plug connector 3 inside the first battery module 1 into the plug slot 4 inside the second battery module 2, the positive and negative electrodes of the first battery module 1 and the second battery module 2 are connected, so that it is convenient to combine multiple first battery modules 1 and second battery modules 2 in series, and the operation is convenient and quick. At the same time, by plugging the plug connector 3 into the inside of the plug slot 4, the up and down movement of the first battery module 1 and the second battery module 2 will be restricted. When the first battery module 1 and the second battery module 2 are connected to each other in series, one end of the two card blocks 13 is rotated so that one end of the two card blocks 13 is respectively engaged in the inside of the limit block 14, so that the first battery module 1 and the second battery module 2 are fixed together, the forward and backward movement of the first battery module 1 and the second battery module 2 is restricted, and poor contact between the first battery module 1 and the second battery module 2 is avoided.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
