BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a front view of an energy storage device provided by the present invention; Fig. 2 is a top view of the energy storage device shown in Fig. 1; Fig. 3 1s a circuit connection diagram of the energy storage device shown in Fig. 1; and Fig. 4 is an enlarged view of region A shown in Fig. 2.
DETAILED DESCRIPTION OF THE PRESENT INVENTION To make purposes, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments illustrated in the description are used for only explaining the present invention, rather than limiting the present invention.
Referring to Figs. 1-4, the present invention provides an energy storage device 100 which is mainly used for facilitating the installation of an energy storage battery pack.
In an embodiment of the present invention, the energy storage device 100 includes a container 10, as well as an energy storage battery pack 20 and a power converter module 30 which are accommodated in the container 10. The container 10 is provided with an accommodation space 101 for accommodating the energy storage battery pack 20 and the power converter module 30, a plurality of double-doors 102 for communicating the accommodation space 101 with the outside, and a canopy 103; the plurality of double-doors 102 are arranged at one side of the container 10; and the canopy 103 is arranged at one end of the container 10. The energy storage battery pack 20 includes a plurality of battery clusters 201, which are connected in parallel and arranged at intervals; the plurality of battery clusters 201 are accommodated at one side of the accommodation space 101 near the double-doors 102; and each battery cluster 201 directly faces a double-door 102. The power converter module 30 is accommodated at one end of the accommodation space 101 near the canopy 103, and used for performing AC/DC conversion and connecting the energy storage battery pack 20 into a power grid 200.
It is understandable that the double-doors 102 can serve as windows through which the energy storage battery pack 20enters the container 10, so that each battery cluster 201 can be conveniently loaded into the container 10 through the corresponding double-door 102 by using tools such as forklifts, thereby shortening the time for mounting the energy storage battery pack 20. Meanwhile, the double-doors 102 can also serve as maintenance and replacement windows of the energy storage battery pack 20, so that workers do not have to maintain and replace the energy storage battery pack 20 in the narrow container 10. The canopy 103 plays a role of blocking rain. It should be explained here that, for the convenience of the workers to check or operate the working state of the power converter module 30, an access door (not shown) for the workers to enter and exit is further arranged at one end of the container 10 provided with the power converter module 30, and the canopy 103 is used for preventing the access door from being corroded by rain and rusted.
Further, the side of the energy storage battery pack 20 far away from the double-doors 102 is spaced from an inner wall of the container 10 to form an overhaul channel 104. The overhaul channel 104 provides a space for the workers to perform daily overhaul on the energy storage battery pack 20, thereby facilitating the workers to check the working state of the energy storage battery pack 20.
More specifically, the energy storage device 100 further includes electrical connection components 40 which are fixed on the inner wall of the container 10 and located above the overhaul channel 104. The electrical connection components 40 connect the plurality of battery clusters 201 in parallel and then are electrically connected with the power converter module 30. It is understandable that the electrical connection components 40 are arranged above the overhaul channel 104.On one hand, the workers can wire and overhaul circuits conveniently to find out problems in time, and on the other hand, the electrical connection components 40 can be far away from the energy storage battery pack 20 to improve the safety performance. For example, the electrical connection components 40 can be disconnected rapidly when the energy storage battery pack 20 goes wrong, or the use of the energy storage battery pack 20 will not be affected by defective spark of the electrical connection components 40.
In the present embodiment, the power converter module 30 includes two bidirectional energy storage converters 301; and the bidirectional energy storage converters 301 are electrically connected with the same number of battery clusters 201 through the electrical connection components 40. Correspondingly, each electrical connection component 40 includes a plurality of parallel copper bars 401; each battery cluster 201 includes at least two battery modules 2011; and each parallel copper bar 401 connects the battery modules 2011 in one battery cluster 201 in parallel and then is electrically connected with the corresponding bidirectional energy storage converter 301.
Further, the energy storage device 100 further includes a battery management system 50 which is electrically connected with the energy storage battery pack 20, the power converter module 30 and the electrical connection components 40 for controlling the working state of the energy storage device 100. For example, the battery management system 50 can be used for monitoring a voltage state and a temperature state of each battery module 2011 during working to prevent the battery module 2011 from being over-charged, over-discharged and over-heated. The battery management system 50 can also be used for automatically controlling the working state of the power converter module 30, so that AC of the power grid 200 is converted into DC in low power consumption periods and then is charged into the energy storage battery pack 20, or DC of the energy storage battery pack 20 1s converted into the AC in high power consumption periods and then is inputted into the power grid 200 for use.
Preferably, to prevent the battery module 2011 from being over-heated, the battery management system 50 is provided with an air conditioning component 501. The air conditioning component 501 is accommodated at one end of the accommodation space 101 far away from the power converter module 30, and is provided with an air supply duct 5011 which is located above the energy storage battery pack 20 and fixed on the inner wall of the container 10 for heating or cooling the energy storage battery pack 20. It should be noted here that the power converter module 30 will also generate a large amount of heat when working, so a distance between the air conditioning component 501 and the power converter module 30 should be as long as possible to prevent the heat generated by the power converter module 30 from interfering with the cooling effect of the air conditioning component
501.
Meanwhile, to prevent the battery module 2011 from causing safety accidents of fire or explosion due to overheating, the battery management system 50 is further provided with a fire-fighting component 502 which includes a fire-fighting pipeline 5021 and a plurality of alarms 5022 arranged on the fire-fighting pipeline 5021; and the fire-fighting pipeline 5021 is connected with the inner wall of the container 10 and located above the energy storage battery pack 20. The plurality of alarms 5022 correspond to the plurality of battery clusters 201 one by one; and the fire-fighting pipeline 5021 is provided with at least one spray nozzle 5023 for spraying fire extinguishing substances above each battery cluster 201. In the present embodiment, the alarms 5022 are used for detecting temperature and smoke information in the container 10 to detect whether the battery module 2011 has a potential fire hazard; and the battery management system 50 is used for controlling a switch of the spray nozzle 5023 according to the detection information of the alarms 5022.
The present invention is not only limited to the illustration in the description and the embodiments, so other advantages and modifications can be realized easily by those skilled in the art.
Therefore, the present invention is not limited to specific details, representative equipment, and graphical examples shown and described herein without departing from the spirit and scope of general concepts defined by claims and equivalent scopes.
