  Below, based on the arrow shown in the figure, it demonstrates by defining the front-back direction, the left-right direction, and the up-down direction.

  First, the installation structure 100 which concerns on 1st embodiment of the installation structure of the storage battery system which concerns on this invention is demonstrated using FIG.1 and FIG.2. The installation structure 100 is a structure for installing the storage battery system 10 outdoors.

  The storage battery system 10 charges and stores electric power for use in the house 1 and discharges it appropriately so that it can be used in the house 1. Moreover, the shielding room 20 covers the storage battery system 10 arrange | positioned outside the house 1 from the exterior, and shields the said storage battery system 10 from sunlight, a wind and rain. The storage battery system 10 and the shielding room 20 are arranged along the outer wall 1a (front side surface) of the house 1. The shielding chamber 20 is provided with an opening mechanism 30 that opens so as to communicate the inside and the outside of the shielding chamber 20.

  Below, the specific structure of the storage battery system 10 and the shielding room 20 is demonstrated.

  The storage battery system 10 is disposed immediately in front of the outer wall 1 a of the house 1. The storage battery system 10 mainly includes a housing 11, a storage battery 12, an inverter 13, and a radiator 14.

  The casing 11 constitutes an outline of the storage battery system 10 and is for housing other components of the storage battery system 10. The housing 11 is formed in a substantially rectangular parallelepiped box shape. The casing 11 is formed with a discharge portion 11a.

  The discharge part 11 a communicates the inside and the outside of the housing 11. The discharge part 11a is formed in the lower part of the front side surface of the housing 11 (the part extending from the lower end part to the vicinity of the upper and lower central part). The discharge part 11a is formed by vertically arranging a plurality of substantially rectangular through holes whose longitudinal direction is in the left-right direction.

Here, the rear end portion (the inner end portion of the casing 11) of the discharge portion 11a is an embodiment of the “introduction port” of the discharge portion according to the present invention, and the front end portion (the casing) of the discharge portion 11a. 11 is an embodiment of the “discharge port” of the discharge portion according to the present invention. In the present embodiment, the discharge portion 11a is formed on the thin plate-like surface of the housing 11 so as to have a slit shape, and the length of the discharge portion 11a in the air flow direction (front-rear direction). Is so short that the inlet and outlet are almost coincident. For this reason, in this embodiment, it demonstrates without making a distinction especially in an inlet and a discharge port.
In the fifth embodiment (see FIG. 9) to be described later, the introduction port and the discharge port of the discharge unit are disposed at different positions (separated positions), and thus are described separately.

  The storage battery 12 is configured to be able to charge and discharge electric power. The storage battery 12 is composed of a lithium ion battery. Specifically, the storage battery 12 is composed of a plurality of cells 12a. The storage battery 12 is arranged from the upper end of the rear part in the housing 11 to the lower end.

The inverter 13 converts electric power as appropriate. The inverter 13 is arranged at the upper part of the front part in the housing 11. The inverter 13 can convert AC power supplied from the outside into DC power and charge the storage battery 12. Further, the inverter 13 can convert the DC power from the storage battery 12 into AC power and output it.
For example, the inverter 13 is connected to a commercial power source or a solar power generation unit of the house 1, and can charge the storage battery 12 with power from the commercial power source or the like. Moreover, the inverter 13 is connected to a load (such as an indoor outlet or an electric device) of the house 1, and can output electric power charged in the inverter 13 and supply it to the load.

  The radiator 14 is for accelerating the radiation of heat generated from the inverter 13. The radiator 14 is made of a material that easily conducts heat (for example, aluminum). The radiator 14 is disposed at the lower part of the front part in the housing 11, that is, below the inverter 13. The top surface of the radiator 14 is in contact with the bottom surface of the inverter 13. As a result, heat generated from the inverter 13 is easily conducted to the radiator 14. A plurality of fins 14 a formed in a plate shape are provided on the front surface of the radiator 14, particularly on the portion facing the introduction port of the discharge portion 11 a of the housing 11. Thereby, the surface area of the front surface of the radiator 14 can be increased, and the heat of the radiator 14 can be easily conducted (radiated) from the fins 14a to the air.

  The shielding chamber 20 is an embodiment of the shielding member according to the present invention. The shielding room 20 mainly includes a side wall 21 and a roof 22.

  The side wall 21 is erected on the side of the storage battery system 10 and covers the storage battery system 10 from the side. The side wall 21 is composed of a plurality of plate-like members arranged in front of the storage battery system 10 and both left and right sides. The front side surface of the side wall 21 is disposed so as to be parallel to the front side surface of the housing 11 of the storage battery system 10, and is disposed slightly apart so as not to contact the front side surface of the housing 11. . The storage battery system 10 is covered from the side by the side wall 21 and the outer wall 1 a of the house 1. The side wall 21 is provided with a door (not shown). The storage battery system 10 can be maintained by entering and exiting the shielding chamber 20 from the door.

  The roof 22 covers the storage battery system 10 from above. The roof 22 is composed of a plate-like member, and is disposed on the upper portion of the side wall 21 in a state of being inclined so as to rise from the front toward the rear. The front lower end of the roof 22 is rotatably connected to the upper end of the front side surface of the side wall 21 via a rotation shaft 22a whose longitudinal direction is the left-right direction. The rear upper end of the roof 22 extends to the vicinity of the outer wall 1 a of the house 1.

  The opening mechanism 30 mainly includes a support portion 31, a closing plate 32, and a shape memory alloy spring 33.

  The support portion 31 supports other constituent members of the opening mechanism 30. The support portion 31 is fixed to the outer wall 1 a of the house 1 below the roof 22.

  The closing plate 32 is disposed between the roof 22 and the support portion 31. The closing plate 32 is composed of a plate-like member. The closing plate 32 is arranged from the vicinity of the rear upper end of the roof 22 to the vicinity of the support portion 31, thereby substantially closing the gap between the roof 22 and the support portion 31.

  The shape memory alloy spring 33 is a member configured to expand and contract according to temperature. The shape memory alloy spring 33 is configured to expand when it reaches a predetermined temperature or higher, and contracts when the temperature becomes lower than the predetermined temperature. The shape memory alloy spring 33 is disposed between the support portion 31 and the closing plate 32 and between the closing plate 32 and the rear upper end of the roof 22.

  The “predetermined temperature” at which the shape memory alloy spring 33 expands and contracts can be arbitrarily set. In the present embodiment, the temperature is set to a temperature lower by a predetermined value than the upper limit value of the temperature range suitable for use of the storage battery system 10.

  Next, the state of the installation structure 100 when the storage battery system 10 is operating (charging / discharging) will be described with reference to FIGS. 3 and 4.

  First, with reference to FIG. 3, a description will be given of a case where the outdoor air temperature is relatively low, in particular, a case where the snow S is accumulated around the shielding room 20 or the upper part of the roof 22.

  When the storage battery system 10 performs charging / discharging, the inverter 13 generates heat. The heat of the inverter 13 is conducted to the radiator 14 disposed so as to be in contact with the bottom surface of the inverter 13 (see the black arrow in the figure). The heat conducted to the radiator 14 is mainly conducted from the portion where the fins 14a are provided to the air. The air in the vicinity of the fin 14a thus warmed is discharged to the outside of the housing 11 from the discharge portion 11a formed at a position facing the fin 14a (see the white arrow in the figure).

  The warm air discharged from the discharge portion 11 a rises from the lower end portion of the side wall 21 to the upper end portion between the front side surface of the housing 11 and the front side surface of the side wall 21. At this time, the heat of the warm air is conducted to the front side surface of the side wall 21, and the temperature of the entire front side surface of the side wall 21 (from the lower end portion to the upper end portion) rises. Thus, when the temperature of the side wall 21 rises, the heat of the side wall 21 promotes the melting of the snow S that has accumulated on the outside.

  The warm air rising between the front side surface of the housing 11 and the front side surface of the side wall 21 rises rearward and upward along the roof 22 which is further inclined from the upper end portion of the side wall 21. At this time, the heat of this warm air is conducted to the roof 22 and the temperature of the roof 22 rises. When the temperature of the roof 22 rises in this way, the melting of the snow S that has accumulated on the upper part is promoted by the heat of the roof 22.

  Thus, by providing the discharge part 11a (discharge port of the discharge part 11a) at the lower part of the casing 11 (position facing the lower part of the front side surface of the side wall 21), the warm air released from the discharge part 11a The front side surface of the side wall 21 and the roof 22 are warmed over the entire area, and the melting of the snow S that has accumulated on the periphery of the shielding chamber 20 and the upper part of the roof 22 is promoted. As a result, when there is no snow accumulated on the snow S, an operator can enter the shielding chamber 20 through the door provided on the side wall 21 and maintain the internal storage battery system 10. Further, it is possible to prevent the shielding chamber 20 from being damaged by the weight of the snow S that has accumulated snow.

  Further, when the outdoor air temperature is low in this way, the temperature in the shielding chamber 20 is also difficult to rise, so the temperature of the shape memory alloy spring 33 becomes lower than the predetermined temperature, and the shape memory alloy spring 33 is in a contracted state. . In this state, the support portion 31, the closing plate 32, and the roof 22 are in close proximity to each other, and the communication between the space inside the shielding chamber 20 and the outside space is substantially blocked by the closing plate 32. Therefore, the air warmed by the heat from the inverter 13 stays in the shielding chamber 20, and the temperature of the side wall 21 and the roof 22 is more easily warmed.

  In addition, when the outdoor air temperature is low in this way, the air in the housing 11 is also warmed as a whole by the heat generated by the inverter 13, so that a decrease in the temperature of the storage battery 12 can be suppressed. 12 malfunctions can also be prevented.

  Next, the case where outdoor temperature is comparatively high is demonstrated using FIG.

  In this case as well, as in the case where the outdoor temperature is relatively low (see FIG. 3), the heat of the inverter 13 is conducted to the air by the radiator 14, and the warmed air travels along the front side of the side wall 21 and the roof 22. Rise. The temperature in the shielding room 20 is increased by irradiation of air heated by the heat of the inverter 13, outdoor warm air, or sunlight.

  When the temperature in the shielding chamber 20 rises and the temperature of the shape memory alloy spring 33 is warmed to the predetermined temperature or higher, the shape memory alloy spring 33 is in an extended state. In this state, the support part 31, the blocking plate 32, and the roof 22 are in a state of being separated from each other, and the space inside the shielding chamber 20 and the outside space are in communication with each other. Therefore, the warm air in the shielding chamber 20 is released to the outside through the gap between the support portion 31, the blocking plate 32, and the roof 22, and the temperature rise in the shielding chamber 20 is suppressed. In this way, the temperature in the shielding chamber 20 can be kept within a temperature range suitable for use of the storage battery system 10 (temperature lower than the upper limit value).

As described above, the installation structure 100 of the storage battery system 10 according to the present embodiment is as follows.

It is possible to promote the melting of snow on the snow. Thereby, the maintainability of the storage battery system 10 can be improved.

Moreover, the storage battery system 10
The heat dissipator 14 is disposed so as to face the inlet of the discharge part 11 a and dissipates heat from the inverter 13 disposed inside the housing 11.

  With this configuration, heat generated in the inverter 13 can be radiated in the vicinity of the inlet of the discharge portion 11a, and warm air can be easily discharged from the discharge portion 11a.

The installation structure 100 is
The shielding chamber 20 is formed so as to cover the storage battery system 10 from the outside,
An opening mechanism 30 is further provided that is provided in the upper part of the shielding chamber 20 and opens so as to communicate between the inside and the outside of the shielding chamber 20 when the temperature inside the shielding chamber 20 rises to a predetermined temperature or higher. To do.

  By comprising in this way, the warm air in the shielding room 20 can be discharge | released outside, and the temperature rise in the said shielding room 20 can be suppressed.

The roof 22 is
The side wall 21 is inclined and arranged so as to rise from the end portion (front end portion) on the front side surface side toward the other end portion (rear end portion).

  By comprising in this way, the whole area | region of the roof 22 can be warmed using the warm air which rose along the front side surface of the side wall 21. FIG. As a result, it is possible to promote the melting of the snow S that has accumulated on the roof 22 and to prevent the shielding chamber 20 from being damaged by the weight of the snow S.

  As described above, in the installation structure 100 according to the present embodiment, when the outdoor air temperature is relatively low (when snow is accumulated), the storage battery 12 is warmed by the heat from the inverter 13 and around the shielding room 20. It is possible to promote the melting of snow S. Further, when the outdoor temperature is relatively high, the temperature inside the shielding chamber 20 can be maintained at an appropriate temperature by communicating the inside and the outside of the shielding chamber 20 with the opening mechanism 30. That is, the installation structure 100 can provide an installation environment suitable for the storage battery system 10 regardless of whether the outdoor temperature is relatively low or high.

  In the present embodiment, the storage battery system 10 charges and discharges (charges / discharges) power for use in the house 1. However, the present invention uses the power used by the storage battery system 10 for charging and discharging. It is not limited to. For example, it is possible to adopt a configuration in which the power is used in various buildings such as office buildings, station buildings, and hotels, and a configuration in which various types of electrical equipment are used.

The specific configurations of the storage battery system and the shielding member according to the present invention are not limited to the storage battery system 10 and the shielding room 20 according to the present embodiment.
For example, although the storage battery 12 is a lithium ion battery, other batteries (for example, a nickel metal hydride battery) may be used. Moreover, although the housing | casing 11 shall be a substantially rectangular parallelepiped, the shape is not limited. Further, the arrangement of the members in the housing 11 is not limited. For example, the inverter 13 may be disposed in the lower part of the housing 11. The shape of the radiator 14 is not limited, and any shape that can radiate the heat of the inverter 13 may be used.
Further, for example, the shape of the shielding chamber 20 is not limited to the present embodiment, and any shape may be used as long as it is erected on at least one side of the storage battery system 10. Moreover, although the shielding room 20 shall cover the storage battery system 10 with the outer wall 1a of the house 1, the structure which covers the storage battery system 10 by the shielding room 20 alone may be sufficient.

  Further, in the present embodiment, the front side surface of the casing 11 in which the discharge portion 11a is formed and the front side surface of the side wall 21 that faces the discharge portion 11a are arranged in parallel. It is not limited to.

For example, using a temperature sensor that detects the temperature inside the shielding chamber 20, an actuator that rotates the roof 22 of the shielding chamber 20, and a control device that controls the operation of the actuator based on the temperature detected by the temperature sensor. When the temperature inside the shielding chamber 20 rises to a predetermined temperature or more, the roof 22 can be rotated upward so that the inside of the shielding chamber 20 communicates with the outside.

  Moreover, in this embodiment, it was set as the structure which can be opened so that the inside and the exterior of the said shielding chamber 20 may be connected by rotating the roof 22 of the shielding chamber 20, but this invention is this. It is not limited to. For example, a window that can be opened and closed is provided on the side wall 21 or the roof 22 of the shielding room 20, and the inside of the shielding room 20 is communicated with the outside by opening the window.

  In addition, since it is the structure which warms the side wall 21 of the shielding chamber 20 with the warm air which discharge | releases from the discharge | release part 11a of the housing | casing 11 and raises, it is desirable that the said discharge | release part 11a is formed in the lowest position of the housing | casing 11. . This makes it possible to warm a wide range from the vicinity of the lower end portion of the side wall 21 of the shielding chamber 20 to the upper end portion.

  Further, the front side surface of the housing 11 and the front side surface of the side wall 21 are at a suitable distance so that the heat of warm air released from the discharge portion 11a of the housing 11 is sufficiently conducted to the side wall 21 of the shielding chamber 20. It is desirable that the warm air discharged from the discharge portion 11a be separated by a close distance that can sufficiently contact the side wall 21.

  Moreover, it is desirable that the side wall 21 and the roof 22 of the shielding chamber 20 be formed of a material that easily conducts heat so as to be easily warmed (for example, aluminum). Thereby, it is possible to further promote the melting of the snow S that has accumulated snow.

The top surface of the radiator 214 is in contact with the bottom surface of the inverter 13. The front end portion of the radiator 214 extends to the front of the casing 11 through the discharge portion 211 a of the casing 11, and the front side surface of the radiator 214 is in contact with the front side surface of the side wall 21.

  In the installation structure 200 configured as described above, the heat conducted from the inverter 13 to the radiator 214 is conducted from the front end of the radiator 214 to the front side surface of the side wall 21 (see the black arrow in the figure). ). This makes it easier to warm the front side surface of the side wall 21 than in the case of the first embodiment, and as a result, snow melting of the snow S that has accumulated on the outside of the side wall 21 can be more effectively promoted.

As described above, the radiator 214 according to the present embodiment is
It extends from the inside of the housing 11 to the outside via the discharge part 211 a and contacts the shielding chamber 20.

  In the installation structure 300 configured as described above, the heat of the inverter 13 is conducted to the air by the radiator 14 as in the first embodiment, and the warmed air travels along the front side surface of the side wall 21 and the roof 22. To rise. At this time, the warmed air rotates the windmill 341. The rotational power of the windmill 341 is transmitted to the generator 342 via the windmill shaft 341a, and the generator 342 generates power.

  The electric power generated by the generator 342 is charged, for example, in the storage battery system 10 or a separately provided storage battery system (not shown). This charged power can be used as appropriate in the house 1 or the like. For example, as shown in FIGS. 6 and 7, an upwardly directed fan 343 is installed in the lower part of the space between the storage battery system 10 and the front side surface of the side wall 21, and the electric power generated by the generator 342 is used. A configuration in which the fan 343 is driven is also possible. With such a configuration, the fan 343 can promote air rise and air can be circulated efficiently.

  As described above, in the installation structure 300 according to the third embodiment, power generation can be performed using the air flow in the shielding chamber 20, and the energy can be effectively used.

  Below, the installation structure 400 which concerns on 4th embodiment of the installation structure of the storage battery system which concerns on this invention is demonstrated using FIG. In the following description of the fourth embodiment, only the configuration different from that of the first embodiment will be described, and the same components as those of the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  An opening 421a is formed in the side wall 21 of the shielding chamber 20 according to the fourth embodiment. The opening 421a communicates the inside and the outside of the shielding chamber 20 with each other. The opening 421a is formed at the front lower end of the left side surface of the side wall 21 (a position facing the gap between the front side surface of the housing 11 and the front side surface of the side wall 21 in a side view). The opening 421a is formed by vertically arranging a plurality of substantially rectangular through holes whose longitudinal direction is the front-rear direction.

  In the installation structure 400 configured as described above, the heat of the inverter 13 is conducted to the air by the radiator 14 as in the first embodiment, and the warmed air is discharged from the discharge portion 11a of the housing 11. . The warmed air tends to rise between the front side surface of the housing 11 and the front side surface of the side wall 21. At this time, as the heated air rises, air having a relatively low temperature (from the air heated by the heat of the inverter 13) is taken into the shielding chamber 20 from the outside through the opening 421a of the side wall 21. It is. The air having a relatively low temperature pushes up warm air released from the discharge portion 11a of the housing 11 and promotes the rise of the warm air. Thus, by utilizing the so-called chimney effect, air can be circulated efficiently.

  Below, the installation structure 500 which concerns on 5th embodiment of the installation structure of the storage battery system which concerns on this invention is demonstrated using FIG. In the following description of the fifth embodiment, only the configuration different from that of the first embodiment will be described, and the same configuration as that of the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

  In the storage battery system 10 according to the fifth embodiment, the storage battery 12 is disposed in the lower part of the housing 11. Further, the inverter 13 is disposed at the upper part of the rear part in the housing 11. Further, the radiator 14 is disposed at the upper part of the front part in the housing 11.

  In the housing 11 according to the fifth embodiment, a discharge portion 511a is formed instead of the discharge portion 11a in the first embodiment. The discharge part 511 a communicates the inside and the outside of the housing 11. The discharge part 511a is formed by a cylindrical member. The inlet 511b of the discharge part 511a communicates with the upper part of the front side surface of the housing 11 and is disposed so as to face the fins 14a of the radiator 14. The discharge port 511 c of the discharge part 511 a is disposed so as to face the lower part of the front side surface of the side wall 21 and communicates with the outside of the housing 11. The discharge part 511a is formed in an appropriately bent shape so as to communicate the introduction port 511b and the discharge port 511c.

  In the installation structure 500 configured as described above, warm air in the housing 11 flows into the discharge portion 511a from the introduction port 511b, and passes through the discharge portion 511a to the outside of the housing 11 from the discharge port 511c. And released. The warm air discharged from the discharge port 511c of the discharge part 511a rises along the side wall 21 and can raise the temperature of the side wall 21.

  At this time, since the inlet 511b of the discharge portion 511a is disposed so as to face the fin 14a of the radiator 14, warm air in the vicinity of the fin 14a easily flows into the discharge portion 511a.

  As shown in the installation structure 500 according to the fifth embodiment, the shape of the discharge portion according to the present invention is not limited to the through-hole as in the discharge portion 11a according to the first embodiment, but an appropriate member (cylinder) The air may be guided by a member or the like. In this case, the shape of the discharge portion 511a is not limited as long as warm air in the housing 11 is discharged from a position (discharge port 511c) facing the lower portion of the side wall 21. That is, as in the installation structure 500, it is possible to adopt a configuration in which warm air is taken into the discharge part 511a from the upper part instead of the lower part of the housing 11. Further, the inlet 511b of the discharge portion 511a is provided at a position where warm air is likely to be generated (for example, in the vicinity of the fin 14a of the radiator 14 or in the vicinity of the inverter 13) or a position where warm air is likely to accumulate (for example, in the casing 11). It is possible to exhaust the warm air in the housing 11 efficiently.

In addition, the specific structure of the shielding member according to the present invention is not limited to the shielding chamber 20 according to each of the above-described embodiments, and may be any structure as long as it is erected on at least one side of the storage battery system 10.
For example, as shown to Fig.10 (a), the structure which arrange | positions the plate-shaped shielding member 620 only to the front side of the housing | casing 11 of the storage battery system 10 may be sufficient. In this case, warm air rises between the front side surface of the housing 11 and the shielding member 620.
10B, the C-shaped shielding member 720 in plan view may be arranged so as to contact the front side surface of the housing 11 of the storage battery system 10. In this case, the front side surface of the housing 11 is covered from the side by the shielding member 720, and warm air rises in the space surrounded by the front side surface of the housing 11 and the shielding member 720. . By enclosing the space in which warm air rises from the side in this way, it can be expected that the air rises due to the chimney effect.
