An auxiliary heat sink 316 is attached to the other side of the thermoelectric element 311 and an auxiliary fan 315 is installed on the auxiliary heat sink 316 to change the flow of air.

The inlet heat sink 313 and the auxiliary heat sink 316 may be formed of a conventional heat sink such as copper or aluminum and the inlet fan 312 and the auxiliary fan 315 may be made of conventional ventilation You can use a fan or a heat-dissipating fan. It is preferable that the inlet heat sink 313 is larger in size than the auxiliary heat sink 316 for efficiency and the blowing capacity of the inlet fan 312 is larger than that of the auxiliary fan 315, It is preferable to use a larger one.

Referring to FIG. 4, a description will be given of the step of circulating the internal temperature of the battery 10 according to the present invention on the basis of the operations of the air circulation unit 320 and the temperature change unit 310 as described above. 4 is a flowchart showing a step of keeping the internal temperature constant in the storage battery 10.

As described above, the temperature sensor 110 measures the internal temperature value tc of the storage ground 10 in real time and transmits it to the control unit 200 in real time Conduct. If the internal temperature value tc is within the range of the internal temperature maximum value tc.max or higher than the internal temperature minimum value tc.min already input in the controller 200, The temperature control unit 300 does not need to operate.

If the internal temperature value tc deviates from the above range, it means that the internal temperature of the storage battery 10 is not normal. Therefore, the controller 200 detects the internal temperature value tc, A thermoelectric element operation step (S1-2) is performed in which a current is supplied to the thermoelectric element (311) for operation.

Here, if the internal temperature value tc is less than the internal temperature minimum value tc.min, it means that the internal temperature of the storage battery 10 is excessively low, so that the thermoelectric element 311 is heated.

Likewise, if the internal temperature value tc exceeds the internal temperature maximum value tc.max, it means that the internal temperature of the storage ground 10 is too high, so that the thermoelectric element 311 must be cooled .

If the thermoelectric element is heated or cooled through the thermoelement operation step S1-2 as described above, the heat sink 313 will also be heated or cooled accordingly. At this time, the control panel 200 performs an air circulation step (S1-3) for operating the inlet fan 312 and the auxiliary fan 315. The inlet fan 312 absorbs the abnormal temperature air E-A in the storage battery 10 and transfers it to the inlet heat sink 313 by performing the step S1-3. The abnormal temperature air EA which has been excessively heated or cooled is cooled or heated while passing over the inlet fan 312 and the inlet heat sink 313 and is converted into the normal temperature air OA, The air is discharged along the air circulation passage 321 by the driving pressure of the storage tank 312 and then discharged into the storage battery 10 through the plurality of outlets 322 as described above, So that the internal temperature value tc of the internal combustion engine can return to normal.

The auxiliary fan 315 operates to prevent the thermoelectric element 311 from being excessively overheated or overcooled.

If the internal temperature value tc of the storage battery 10 is returned to the range of the internal temperature maximum value tc.max or more within the internal temperature minimum value tc.min, An internal air intake stop step S1-4 for stopping the operation of the thermoelectric element 311 and the drawing fan 312 is performed.

At this time, even though the thermoelectric element 311 interrupts the current to interrupt the operation, the auxiliary fan 315 may still be cooled or overheated, so that the auxiliary fan 315 may operate after the step S1-4. At this time, a separate sensor may be provided in the thermoelectric element 311 to measure the temperature of the thermoelectric element 311, or to predict the temperature using the previously calculated temperature change of the thermoelectric element 311, The controller 200 performs a thermoelectric-element temperature measurement step S1-5 for measuring the thermo-electric-element temperature th, and the thermo-electric-element temperature th is measured as a result of the thermo- When the temperature of the sub-fan 315 is within the range of the maximum value (th.min) of the thermoelectric element temperature or below the maximum value (th.max) of the thermoelectric element temperature, The internal temperature of the storage battery 10 can be adjusted by completing the operation of the temperature changing part 310. [

5 is a flowchart illustrating a process of distributing or switching the power of the battery unit 100 using the priority changeover unit 400. FIG. max) is 100%, and the voltage range from 0% in the fully discharged state to 100% in the maximum voltage (V. max) state is divided into four sections. Hereinafter, power supply and transfer of the power storage unit 10 will be described with reference to FIGS. 5 and 6. FIG.

Prior to description, FIG. 6 shows four intervals, which may be set arbitrarily according to the needs of the user. At least two intervals may be set. More than three intervals are preferable for implementing priority switching.

Prior to the explanation, the priorities of the usage destinations E1 to E6 shown in FIG. 1 are the facilities in which E1 is the most essential, the highest priority, followed by E2, E3, E4 and E5, , And E6 have the lowest priority, as an example.

As shown in FIG. 5, the control unit 200 performs a power supply step (S2-1) for supplying electric power to each of the usage destinations (E1 to E6) when a power supply request is made.

In the power supply step S2-1, the controller 200 measures the voltage V in the battery unit 100. When the voltage V is in the first interval, that is, when the voltage V (V.Lv1) and the maximum voltage (V.Max), the voltage (V) is sufficient so that the battery unit 100 does not need to be switched, E1 to E6.

 When the step S2-1 continues, the voltage V decreases as the power is not supplied from the photovoltaic power generator 600, and enters the second section. The second section is a section that is less than the two-step changeover voltage (V.Lv2) and less than the one-step changeover voltage (V.Lv1).

When the voltage V enters the second section, the controller 200 performs the first switching step S2-2 for cutting off the power supply to the use destination E6 having the lowest priority. At this time, since the switching can be performed in the distribution panel 410, the controller 200 can perform the switching function by operating a power switch of the power line connected to the use place E6 in the distribution board 410. [

There are two cases in which the voltage V deviates from the second section in the state where the step S2-2 is being performed. The voltage V increases due to the supply of additional power, When the changeover voltage V.Lv1 is exceeded, the first transfer restoration step S2-3 for restoring the transfer of the transfer destination E6 is performed again and then the power supply step S2-1 is performed again Return.

When the voltage V is continuously decreased to be less than the two-step changeover voltage V.Lv2, the voltage V is higher than the three-step changeover voltage V.Lv3, And the second switching step S2-4 for cutting off the electric power of the second lowest usage destination E5 is performed.

There are two cases in which the voltage V deviates from the third section in the state where the step S2-4 is being performed. The voltage V increases due to the supply of additional power, When the step-change voltage V.Lv2 is exceeded, a second transfer restoring step S2-5 for restoring the transfer of the transfer destination E5 and supplying the power again is performed. At this time, since the use destination E6 having the lowest priority is still in the switched state after the second transfer recovery step S2-5, the controller 200 continuously measures the voltage V, It may be determined whether or not to perform the transfer restoration step (S2-3).

When the voltage V continuously decreases and becomes less than the three-step transfer voltage V.Lv2, the voltage V belongs to a fourth section that is less than the three-step transfer voltage V.Lv3, Which means that the voltage V is almost exhausted. If it is assumed that the highest priority usage destination E1 of the usage destinations E1 to E6 is a facility where the power supply should not be interrupted as the most essential usage destination, it is possible to save the voltage V only to the highest priority usage destination E1 It would be desirable to supply. Therefore, when the essential use place E1 which is not required to stop the power supply is set as the highest priority, the control unit 200 switches all the used places E2 to E4 except for the highest priority use place E1 The final switching step S2-6 is performed. Then, in accordance with the final switching step S2-6, a status transmission step S2-7 is performed to notify the displays 510, 520, and 530 that all of the destinations other than the highest priority destination E1 are switched . If the status transmission step S2-7 is performed as described above, the user who has transmitted the status may take appropriate measures to restore the voltage V. [
