Description

Technology Field

[0001] The present invention relates to a detachable battery ESS power generation device assembly in the field of electricity, and more specifically, to an improved detachable battery ESS power generation device assembly in which a plurality of batteries are assembled into a single battery module and the ESS pack is implemented by slidingly attaching and detachably connecting this battery module to a single case, thereby facilitating assembly and installation; each battery cell is monitored in real-time by a non-contact IR (Infrared Ray) sensor so that overheating can be detected immediately, allowing for the prediction of defects before temperature overheating and immediate replacement to prevent safety accidents; and only the relevant battery can be easily and quickly replaced before an accident occurs, thereby preventing safety accidents such as ignition. Background Technology

[0003] Generally, an Energy Storage System (ESS) is a device that stores electrical energy using a device or physical medium, and is typically a device that stores hundreds to thousands of kWh or more of power compared to the batteries used in ordinary households or small batteries used in electronic products.

[0004] These ESSs can be installed and operated in the power system at power generation, transmission and distribution, and consumer sites, and are used for functions such as frequency regulation, stabilization of renewable energy generator output, peak shaving, load leveling, and emergency power supply.

[0005] Therefore, ESS can contribute to improving energy efficiency, enhancing the utilization of new and renewable energy, and stabilizing the power supply system by storing electrical energy when it is used sparingly and supplying it when needed.

[0006] Energy storage in ESS can be broadly classified into physical energy storage and chemical energy storage depending on the storage method.

[0007] Representative physical energy storage methods include pumped-storage hydropower, compressed air storage, and flywheels, while chemical energy storage methods include lithium-ion batteries, lead-acid batteries, and NaS batteries.

[0008] ESS devices play a very important role in eco-friendly electricity production methods such as solar and wind power, and future demand is expected to increase explosively. In the case of electric vehicles, the future electric vehicle market is very large, to the extent that countries are competing to present their own roadmaps, and consequently, the demand for batteries is expected to increase explosively.

[0009] In particular, ESS devices used for portable or home use are provided in the form of ESS packs, and are configured with different sizes and weights depending on the storage capacity.

[0010] However, since multiple batteries are housed in a single case according to capacity, if any one of the batteries overheats, it is not possible to check and replace only the affected battery, so there is the inconvenience of having to reorganize the entire ESS pack and take out all the batteries to check them one by one.

[0011] Moreover, the battery installation and removal structure is complex, which makes it very inconvenient to use and has the disadvantage of being difficult to invest in initially.

[0012] In addition, the lack of a function to continuously check the battery status in real time poses an unforeseen cause of fire, and there is also a disadvantage that such a fire can lead to major equipment failures or casualties. Prior art literature

Specific details for implementing the invention

[0027] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0028] Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0029] In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.

[0030] The battery detachable ESS power generation device assembly according to the present invention has a form in which a plurality of battery cells are assembled into a single battery module, and a plurality of assembled battery modules are detachably assembled into a single power generation device case.

[0031] In particular, the present invention includes a structure that can prevent safety accidents by providing a means to monitor each battery cell independently in the power generation device case, thereby checking in advance for the possibility of ignition due to heat generation and replacing it in advance before ignition.

[0032] Furthermore, the present invention enables inspection of each of the multiple battery cells constituting the battery module and allows for independent replacement, thereby providing efficient management characteristics.

[0033] More specifically, as shown in the examples of FIGS. 1 and 2, the battery detachable ESS power generation device assembly according to the present invention includes a power generation device case (100).

[0034] At this time, (a) of FIG. 1 shows a front view of the power generation device case and (b) shows a rear view, and (a) of FIG. 2 shows the front of the power generation device case in an open state and (b) shows the top surface in an open state.

[0035] As with the city, the power generation device case (100) is formed in the shape of a square box, and first, second, and third slots (120, 130, 140) are provided on the left and right sides inside, which are divided vertically by a dividing piece (110).

[0036] And, a battery module (200, see FIG. 3, 4) to be described later is inserted or removed in a sliding manner in the first, second, and third slots (120, 130, 140).

[0037] In particular, the inner rear wall surface of the power generation device case (100) is provided with a busbar (150) that can be connected to a connection terminal (240, see FIG. 4) provided in each battery module (200).

[0038] In addition, it goes without saying that a structure capable of connecting to a signal processing cable terminal (250, see FIG. 4) can also be implemented.

[0039] In addition, handles (160) may be further provided on both sides of the front of the power generation device case (100) to facilitate portability of the power generation device case (100).

[0040] By configuring it in this way, multiple battery modules (200) with multiple battery cells (BTC, see FIG. 4) mounted thereon can be configured to be inserted and removed in a sliding manner into a single power generation device case (100), thereby enabling the integration of battery cells (BTC) and providing the advantage of efficient management. Here, FIG. 4(a) shows an example in which six battery cells (BTC) are mounted in one battery module (200), and FIG. 4(b) shows an example in which four battery cells (BTC) are mounted in one battery module (200).

[0041] Above all, it allows for individual, real-time checking of battery overheating, providing excellent effectiveness in preventing safety accidents.

[0042] In addition, since it can be attached and detached using a sliding mechanism, it has the advantage of freely varying the battery capacity.

[0043] Meanwhile, as shown in the examples of FIGS. 3 and 4, the battery module (200) includes a slim box-shaped module housing (210) with an open top and a housing cover (220) that seals the top of the module housing (210).

[0044] At this time, the housing cover (220) can be fixed to the module housing (210) by a bolt fastening method.

[0045] In addition, a plurality of battery cells (BTC) are mounted in the module housing (210), and the plurality of battery cells (BTC) are protected by a cell cover (CCV).

[0046] Therefore, by loosening the bolt and removing the housing cover (220), each battery cell (BTC) can be partially replaced, and the replacement work is easy.

[0047] Thus, when the battery cell (BTC) is mounted on the module housing (210) and the housing cover (220) is attached, this assembly becomes a battery module (200).

[0048] In addition, a support (230) is provided on the inner bottom surface of the module housing (210).

[0049] The above-mentioned mounting base (230) may be provided with an insulating heat-resistant material so as to be protected from impact when the battery cell (BTC) is mounted.

[0050] Here, a desirable mounting base (230) may be an insulating insulator.

[0051] Of course, it is also possible that the module housing (210) material itself can be processed into the illustrated shape without the above-mentioned mounting bracket (230) so that when the battery cell (BTC) is mounted, it can be fixed in place without movement.

[0052] That is, it is desirable to ensure ease of assembly by configuring the battery assembly position to be specified by the mounting bracket (230) when assembling the battery cell (BTC).

[0053] In addition, a temperature detection sensor (260) capable of detecting whether the battery cell (BTC) is heated is further installed in the module housing (210).

[0054] The above temperature detection sensor (260) is preferably an IR (Infrared Ray) sensor, that is, an infrared sensor that detects temperature in a non-contact manner.

[0055] Since these IR (Infrared Ray) sensors can be monitored in real time, they can detect when the temperature of a battery cell (BTC) begins to rise immediately and transmit the detection result to a controller. The controller then refers to the received result to predict the defect before it overheats and generates an alarm to replace it immediately, thereby allowing the manager to replace it immediately and preventing safety accidents. Additionally, since only the relevant battery can be easily and quickly replaced before an accident occurs, safety accidents such as ignition can be prevented in advance.

[0056] Additionally, a connection terminal (240) is provided on the rear side of the module housing (210) to connect the + and - terminals of each battery cell (BTC) provided in the battery module (200), and this is connected to the busbar (150) described above.

[0057] At this time, the busbar (150) is fixed to the busbar cover (152) as shown in the example of FIG. 5, and a terminal cover (154) is assembled to the busbar (150). The terminal cover (154) is provided with a terminal (not shown) connected to the busbar (150), so that the busbar (150) of the battery module (200) can be converted into a terminal, making it easy to supply and receive power.

[0058] In addition, a signal processing cable terminal (250) is also provided on the rear side of the module housing (210), so that it can also serve as a communication port.

[0059] In addition, as shown in the example of FIG. 6, a PCB (180) is provided on the upper inner side of the power generation device case (100).

[0060] A controller is mounted on the PCB (180), and the controller is electrically connected to and controlled by the IR sensor described above, i.e., the temperature detection sensor (260). Additionally, a control function necessary for managing the battery module (200), such as the management of power supply and output through the busbar (150), is mounted.

[0061] As explained above, the present invention enables the implementation of an ESS pack by assembling multiple batteries into a single battery module and connecting this battery module to a single case in a sliding manner, making assembly and installation easy. Additionally, each battery cell is monitored in real-time by a non-contact IR (Infrared Ray) sensor, allowing for immediate detection of overheating. This enables the prediction of defects before temperature overheating and allows for immediate replacement to prevent safety accidents. Furthermore, only the relevant battery can be easily and quickly replaced before an accident occurs, thereby preventing safety accidents such as ignition. Explanation of the symbols
