On the other hand, the battery 10 can control the humidity so that a constant humidity environment can be maintained in response to the humidity change of the battery module 100.

Generally, a battery composed of a lithium-ion battery forms a lithium hydroxide (LiOH) layer when it comes into contact with moisture caused by moisture, thereby causing oxidation corrosion and shortening the life of the battery. .

To this end, the battery unit 10 of the present invention may further include a humidity adjusting unit (not shown) driven by a control signal received from the outside to control the humidity inside the accommodating unit 310, The adjusting means is not shown in the drawing, but may typically include air conditioners such as a heater or a blower fan.

The charging and discharging module 200 controls charging and discharging of each battery 110 by a control signal transmitted from the control module 400. At the time of charging the battery 110, The charging information and the discharging information of the unit cell 111 may be monitored and the charging may be performed for each cell 111 according to the monitoring result.

In addition, the display module 500 may include a touch panel that provides a user interface (UI), and may be used as input means for inputting set values of the control module 400 along with display of the monitoring information desirable.

Meanwhile, the battery unit 10 according to an embodiment of the present invention has a structure that allows the heat generated from the battery module 100 to be easily discharged to the outside, so that a fire due to deterioration of the battery module 100 It is preferable to be configured so as to compensate for risks or disadvantages.

Specifically, the receiving part 310 for receiving the battery 110 may apply a heat radiation primer to the inner surface thereof so that the heat generated from the battery 110 may be guided to the receiving part 310, So that the heat can be discharged to the outside through the accommodating portion 310.

At this time, the accommodating portion 310 may be made of a thermally conductive material. However, the material of the accommodating portion 310 is not limited as long as it is a thermally conductive material.

The heat-radiating primer is configured to have thermal conductivity to transmit the heat generated from the battery 110 to the receptacle 310 so that the heat can be radiated to the outside. Even if the heat-radiating primer is thermally conductive, There may arise a problem that a heat insulating layer is partially formed due to microcracks generated during curing and microcracks due to elongation due to temperature difference and the heat transfer efficiency to the accommodating portion 310 is lowered.

According to a preferred embodiment of the present invention, the heat dissipation primer is composed of 30 to 120 parts by weight of the nano diamond powder, 30 to 120 parts by weight of the linear metal powder, 1 to 3 parts by weight of the glycols, 1 part by weight.

First, the silicone resin functions as a binder of another composition and has an adhesive force with the inner surface of the receiving portion 310.

The nanodiamond powder has an excellent heat conduction characteristic and a micropore, so that the heat dissipation function is increased by increasing the surface area. The reason for limiting the blending amount of the nano-diamonds as described above is that it is difficult to expect a sufficient heat-dissipating function when the blending amount is less than the blending amount, and when the blending amount is more than the blending amount, the bonding strength between the other blending components is weakened, As shown in FIG.

However, such a coating layer may induce microcracks due to a temperature difference or the like in a curing process after application, and such microcracks lower the thermal conductivity, which is a factor that hinders the heat-dissipating function.

Thus, in this embodiment, the linear metal powder is further added, and the cross-linking action of the paste is performed by the metal powder forming the linear shape, thereby relaxing the tensile force generated in the paste in the curing process and elongation by temperature difference, It is.

For example, when titanium dioxide is used as a nano metal, a basic aqueous solution is prepared, titanium dioxide is added to the basic aqueous solution in an appropriate weight ratio and stirred, and the thus- An example may be presented in which the mixture is reacted at a high temperature for an appropriate time, and after the reaction, the solvent and impurities are removed to crystallize the mixture.

The linear metal powder produced by the various known methods has the same function as the reinforcing fiber in the paste and has a linear structure while nanoing it using a metal material having a high thermal conductivity and a high tensile strength, .

In other words, in the case of a general metal powder, it has a shape close to a sphere and functions only as a filler in a paste. In this embodiment, a linear metal powder is added to reinforce the tensile strength of the paste. In this way, even when microcracks of the paste are controlled or microcracks are generated, the gap of the microcracks is connected to the linear metal powder, so that the heat is transferred through the gap of the microcracks.

The reason why the linear metal powder is added is that the air is conducted during the application of the heat radiation primer, and this air is a point to deteriorate the thermal conductivity in the future, so that the linear metal powder collides with the air Thereby performing the function of physically letting the air entrained by it.

On the other hand, in order to control surface cracking by evaporation of the solvent in the primer, not the crack due to the temperature difference in the curing process of the heat radiation primer, the heat radiation primer is further blended with the glycol.

The glycols lower the capillary tension when the solvent is evaporated in the pores of the paste, thereby reducing the internal tensile stress, thereby inducing shrinkage reduction after curing. That is, cracks due to shrinkage.

Preferably, the glycols are at least one member selected from the group consisting of butyldiglycol, butyltriglycol, butylglycol, methyldiglycol, butylpolyglycol, ethylpolyglycol, methyltriglycol and ethylglycol. .

In addition, in the process of compounding and applying the heat-dissipating primer, metal ions may be eluted to the surface, and the adhesion between the heat-dissipating primer and the interface of the casing may be lowered by adsorption of metal ions. In order to solve this problem, Ions can be combined with tannins which can control the elution of metal ions to the surface, thereby solving the above problems.

As described above, according to the heat dissipating primer of the present embodiment, the battery module 100 can improve the risk of fire due to deterioration of the battery 110 housed therein, and shorten life span.

The switchboard of the present invention may be connected to the control module 400 of the battery unit 10 to input set values and control signals of the control module 400 at a remote location, And a control server 400 for receiving detection information of the battery 110 sensed by the sensing module 300 from the control module 400.

The control server may be connected to a selected one of a wired or wireless communication network to transmit and receive data. For example, the control server may be a TCP / IP and Ethernet communication network based on IP, a mobile communication network 4G, LTE), a Wibro (Wireless Broadband) network, a HSDPA (High Speed Downlink Packet Access) network, a satellite communication network, and a WiFi And may receive and store sensing information for each battery 110 of the battery module 100 from the controller 400. [

In addition, the control server may input an administrator's command including an input device, and may output sensed information on one or more selected batteries 110 through a monitor or the like in response to a request signal input from an administrator.

In addition, if the level of the battery 110 analyzed by the control module 400 is at a dangerous level, the control server transmits the generated alarm signal to the mobile device of the pre-stored manager in an SMS form, It can also be sent as a mail to the administrator's account.

As described above, in the switchboard of the present invention, the manager can check the status of the battery directly in the field through the display module 500, and the same sensing information can be easily confirmed at the remote site by the configuration of the control server.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
