Description

Home ESS (Energy Storage System) Temperature Control Device

[0001] This technology relates to a temperature control device for a home ESS (Energy Storage System).

[0002] In particular, the present invention relates to a home ESS temperature control device that maintains an ESS battery at a constant temperature so that the ESS maintains constant performance.

[0003] ESS, a traditional energy source, is gaining traction thanks to recent technological developments. ESS is used as a power source for a variety of devices, and with the recent increase in the utility of secondary batteries, ESS is also being used in homes.

[0004] When utilizing ESS, various challenges must be overcome, and one that has recently emerged is heat. If ESS batteries are not efficiently cooled from heat generated during charging and discharging, or from external sources, they can experience problems such as a shortened lifespan, malfunctions, and reduced stability.

[0005] These problems can be solved by controlling temperature. Recently, water-cooling systems have been developed and are being utilized to cool ESSs. However, water-cooling systems require complex piping for refrigerant movement, making them complex to design and difficult to manufacture in small sizes.

[0006] The present invention is an invention that solves the above-mentioned problems, and its purpose is to provide an ESS temperature control device that can be manufactured in a small size and used at home.

[0007] A home ESS temperature control device according to one embodiment may include a case in which a battery is accommodated, a temperature control element disposed on one side of the case to control temperature according to current supply, and a heat dissipation unit connected to the temperature control element to dissipate heat.

[0008] The above temperature control element may be characterized in that the control surface can be cooled or heated depending on the power.

[0009] The above heat dissipation unit may be characterized by comprising a transfer pin section having multiple mountain surfaces and a discharge fan section that is connected to the transfer pin section and discharges heat in one direction when power is supplied.

[0010] The case may be characterized by having a leg portion that is longer than the vertical length of the case and is in contact with the ground to separate the lower surface of the case from the ground at both ends.

[0011] The above heat dissipation unit may be characterized by further including a cover body that accommodates the dissipation fan portion and has a plurality of dissipation holes formed therein and is arranged on one side of the case.

[0012] According to one embodiment of the present invention, a temperature control element can control the temperature of an ESS battery and discharge unnecessary heat to the outside, thereby controlling the temperature of the ESS battery, and can be manufactured in a small size so that it can be used in homes.

[0017] Fig. 5 is a bottom exploded perspective view of the ESS temperature control device from Fig. 4 with the temperature control element removed.

[0018] FIG. 1 is a bottom perspective view of an ESS temperature control device of the present invention, FIG. 2 is a bottom exploded perspective view of an ESS temperature control device of the present invention, FIG. 3 is a bottom exploded perspective view of an ESS temperature control device of FIG. 2 with the cover removed, FIG. 4 is a bottom exploded perspective view of an ESS temperature control device of FIG. 3 with the discharge fan removed, and FIG. 5 is a bottom exploded perspective view of an ESS temperature control device of FIG. 4 with the transmission pin removed.

[0019] Referring to the drawings, an embodiment of the present invention is examined. The ESS temperature control device of the present invention can be composed of a case (100), a temperature control element (200), and a heat dissipation unit (300).

[0020] The case (100) is formed in the shape of a rectangular parallelepiped, and a space for accommodating an ESS can be formed inside. The case (100) can be composed of a side wall (120), a lower side (130), and an upper side (110).

[0021] The upper side of the case (100) may be formed to be detachable for replacement of the ESS. Therefore, the user may move the upper side (110) of the case (100) to expose the internal space of the case (100) to the outside. Therefore, the ESS stored inside the case (100) may be replaceable. Meanwhile, the case (100) is not necessarily configured to be detachable only on the upper side (110), and depending on the application, it is not a problem even if a part of the side wall or the lower side of the case (100) is formed to be detachable. In other words, if the interior of the case (100) can be exposed to the outside, there may be no problem.

[0022] Meanwhile, the case (100) is not as described above, and the case (100) itself can be sealed. Therefore, in case of a problem with the ESS, the entire case (100) can be replaced.

[0023] A temperature control element (200) may be arranged on one side of the case (100). More preferably, although not shown in FIG. 1, it may be arranged on the lower side (130) of the case (100), as shown in FIG. 5. The temperature control element (200) may have one side, the control side, cooled or heated depending on the power supply. Here, the control side of the temperature control element (200) may be a side that comes into contact with the case (100). Therefore, the upper side with reference to FIG. 5 may be the control side.

[0024] The temperature control element (200) can cool the control surface when the first power is supplied, and heat the control surface when the second power is supplied. Here, the temperature control element (200) can have different cooling temperatures and heating temperatures depending on the polarity and intensity of the first and second power sources. Here, the opposite surface of the control surface of the temperature control element (200) can be a corresponding surface. The temperature of the corresponding surface can be changed in the opposite direction to that of the control surface. That is, when the control surface of the temperature control element (200) is cooled, the corresponding surface can be heated.

[0025] In the opposite case, when the control surface of the temperature control element (200) is heated, the corresponding surface can be cooled. Here, the temperature control element (200) can be provided in multiple numbers as confirmed in Fig. 5.

[0026] The heat dissipation unit (300) can be connected to the temperature control element (200). The heat dissipation unit (300) can contact the corresponding surface of the temperature control element (200) and serve to dissipate the temperature of the corresponding surface to the outside.

[0027] In this way, the ESS is accommodated in the case (100), and the temperature of the case (100) is controlled through the temperature control element (200), and when necessary, the heat dissipation unit (300) can be operated to release heat to the outside. Therefore, the present invention can easily control the temperature of the ESS battery and can be formed in a compact size. As can be seen from this description, the temperature control element (200) and the heat dissipation unit (300) of the present invention are the features of the present invention, and the heat dissipation unit (300) and the temperature control element (200) will be described in detail with reference to FIGS. 2 to 5.

[0028] As can be seen in Fig. 1, when the heat dissipation unit (300) is observed from the outside, only the cover body (310) can be observed. The cover body (310) can be observed as a rectangular parallelepiped in cross-section similar to the case (100). However, unlike the case (100), the upper side of the cover body (310) may be omitted without any problem. This is because the lower side of the case (100) closes the upper side of the cover body (310). The cover body (310) can have multiple emission holes formed therein. Therefore, the cover body (310) can communicate with the inside and outside air. Therefore, the cover body (310) can dissipate heat generated when the corresponding surface is heated to the outside.

[0029] Meanwhile, in order to prevent the discharge hole of the cover body (310) from being closed, a leg portion (150) may be formed in the case (100). The leg portion (150) serves to keep the cover body (310) away from the ground. Therefore, the discharge hole of the cover body (310) can be prevented from being closed. The shape of the leg portion (150) may not be a problem as long as the cover body (310) is kept away from the ground so that the discharge hole is not closed.

[0030] For example, the leg portion (150) may be formed to be longer than the vertical length between the cover body (310) at the position where the leg portion (150) is formed on the side of the case (100). That is, the lower end of the leg portion (150) may be in contact with the ground to physically lift the cover body (310). Here, the leg portion (150) is formed in a U shape as illustrated in FIG. 2 so that the area in contact with the ground is wide, and thus can stably support the ground. Meanwhile, although the discharge hole is not illustrated, a filter may be arranged to allow air to pass through but prevent external foreign substances from passing through.

[0031] In order for heat to be released through the release hole of the cover body (310), a configuration that forcibly moves the heat is required, which can be achieved through the release fan unit (320) and the transfer pin unit (330), as can be seen in FIGS. 3 and 4, respectively. The release fan unit (320) can generate wind power in one direction when power is supplied. The release fan unit (320) can be configured, for example, with a wing unit and a motor that rotates the wing unit about an axis. Therefore, the release fan unit (320) can forcibly move air when power is supplied. Therefore, the heat generated on the corresponding surface can be discharged to the outside of the cover body (310) through the release hole of the cover body (310).

[0032] The transfer pin unit (330) can physically transfer heat. The transfer pin unit (330) may have a transfer surface (331) formed on the upper side, and a plurality of mountain surfaces (332) extending from the control surface may be formed. Therefore, the transfer pin unit (330) may transfer heat transferred from the control surface through the mountain surfaces (332). Meanwhile, since the mountain surfaces (332) are formed in plurality, the thermal conductivity may be high. The aforementioned discharge fan unit (320) is arranged on the mountain surfaces (332), so that the heat of the corresponding surface may be transferred through the transfer pin unit (330) and released to the outside of the cover body (310).

[0033] Finally, the temperature control element (200), which is a feature of the present invention, may be placed on one side (lower side) of the case (100). The temperature control element (200) may be composed of a control surface and a corresponding surface as described above. The control surface may perform cooling or heating, and the corresponding surface may perform an opposite operation according to the operation of the control surface.

[0034] Meanwhile, the temperature control element (200) may be configured in multiples, and although the lower side of the case (100) is not shown, a pattern may be formed to facilitate temperature control of the temperature control element (200).

[0035] Additionally, an installation groove (131) may be formed on the lower surface of the case (100). The installation groove (131) may partially accommodate a temperature control element (200). Therefore, the temperature (heating, cooling) controlled by the temperature control element (200) can be more easily transmitted to the ESS.

[0036] In this way, the present invention can control the temperature of the ESS even though it is small because the temperature control element (200) can easily control the temperature and release heat to the outside as needed.

[0037] While the present invention has been illustrated and described with reference to specific embodiments thereof, it will be readily apparent to those skilled in the art that various modifications and variations may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.
