また、充電制御部３２は、 電力会社から供給され、インバータ変換器１４によって変換された直流電力を蓄電池３０へ供給したり、蓄電池３０に蓄電された電力をインバータ変換器１４へ供給することによってインバータ変換器１４によって交流電力に変換して電力会社へ供給したり、インバータ変換器１４によって変換された直流電力を配電盤３４に供給したり、蓄電池３０に蓄電された電力を配電盤３４に供給したり、太陽電池１６から供給される電力を充電するための電力として蓄電池３０に供給したり、太陽電池１６から供給される電力をインバータ変換器１４を介して電力会社へ供給したり、発電ユニット１８から供給される電力を充電するための電力として蓄電池３０に供給したり、発電ユニット１８から供給される電力をインバータ変換器１４を介して電力会社へ供給したりする。充電制御部３２による各電力の流れの切換は、制御部３６によって制御される。   In addition, the charging control unit 32 supplies the DC power supplied from the electric power company and converted by the inverter converter 14 to the storage battery 30 or supplies the power stored in the storage battery 30 to the inverter converter 14. The converter 14 converts the power into AC power and supplies it to the power company, supplies the DC power converted by the inverter converter 14 to the switchboard 34, supplies the power stored in the storage battery 30 to the switchboard 34, The power supplied from the solar battery 16 is supplied to the storage battery 30 as the power for charging, the power supplied from the solar battery 16 is supplied to the power company via the inverter converter 14, or supplied from the power generation unit 18.

The control unit 36 performs charging control for the storage battery 30 based on the detection result of the temperature sensor 38.

詳細には、制御部３６は、温度センサ３８によって検出された温度が所定温度（例えば、蓄電池３０が活性状態になる温度範囲である１５〜２０℃等）以下の場合に蓄電池３０を充電する際には、予備充電を行なって、蓄電池３０を昇温してから、蓄電池３０の本格充電を行なう。具体的には、本格充電を行なう際の電流値よりも小さい電流を蓄電池３０に供給することによって予備充電を行い、蓄電池３０の温度が所定温度に達したところで、本格充電するために必要な電流を蓄電池３０に供給することによって本格充電を行なう。   Specifically, the control unit 36 charges the storage battery 30 when the temperature detected by the temperature sensor 38 is equal to or lower than a predetermined temperature (for example, 15 to 20 ° C. that is a temperature range in which the storage battery 30 is activated).

FIG. 3 is a flowchart showing an example of the flow of the charging process of the storage battery 30 performed by the power management device 12 of the building 10 according to the first embodiment of the present invention. Note that the processing in FIG. 3 is started when, for example, a predetermined time for charging using midnight power is reached, or the remaining amount of the storage battery 30 becomes a predetermined value or less, and the storage battery 30 is charged. Start when needed. Moreover, when the power source for charging the storage battery 30 uses late-night power, the power supplied from the power company and converted by the inverter converter 14 is used, and the storage battery 30 needs to be charged. The power of the solar cell 16 and the power generation unit 18 is preferentially used, and when the power of the solar cell 16 and the power generation unit 18 is not sufficient, the power supplied from the power company and converted by the inverter converter 14 is used.

まず、ステップ１００では、温度センサ３８によって蓄電池３０の温度（蓄電池３０近傍の温度）が検出されてステップ１０２へ移行する。すなわち、温度センサ３８の検出結果が制御部３６に入力される。   First, in step 100, the temperature of the storage battery 30 (the temperature in the vicinity of the storage battery 30) is detected by the temperature sensor 38 and the process proceeds to step 102. That is, the detection result of the temperature sensor 38 is input to the control unit 36.

ステップ１０２では、蓄電池３０の温度が所定温度以下か否か制御部３６によって判定され、該判定が肯定された場合にはステップ１０４へ移行し、否定された場合にはステップ１０６へ移行する。   In step 102, the controller 36 determines whether or not the temperature of the storage battery 30 is equal to or lower than a predetermined temperature. If the determination is affirmative, the process proceeds to step 104, and if the determination is negative, the process proceeds to step 106.

ステップ１０４では、蓄電池３０が予備充電されるように制御部３６によって制御されてステップ１０８へ移行する。すなわち、制御部３６が充電制御部３２を制御することによって本格充電時よりも小さい電流を蓄電池３０に供給することで予備充電を行なって、蓄電池３０を昇温させる。   In step 104, the control unit 36 controls the storage battery 30 to be precharged, and the process proceeds to step 108. That is, the control unit 36 controls the charge control unit 32 to supply the storage battery 30 with a current smaller than that at the time of full-scale charging, so that the storage battery 30 is heated.

ステップ１０６では、蓄電池３０が活性状態となる温度であると判断し、本格充電が行なわれてステップ１０８へ移行する。すなわち、所定温度以上の場合には、制御部３６が充電制御部３２を制御することによって予備充電時よりも大きい電流である、蓄電池３０を充電するために必要な電流を蓄電池３０に供給することで蓄電池３０を充電する。   In step 106, it is determined that the temperature is such that the storage battery 30 is activated, and full charge is performed, and the routine proceeds to step 108. That is, when the temperature is equal to or higher than the predetermined temperature, the control unit 36 controls the charge control unit 32 to supply the storage battery 30 with a current required for charging the storage battery 30, which is a larger current than that during preliminary charging. To charge the storage battery 30.

そして、ステップ１０８では、充電終了か否か制御部３６によって判定される。該判定は、蓄電池３０の残量を充電制御部３２が監視しながら充電すると共に、電力の監視結果を制御部３６へ出力し、制御部３６が蓄電池３０の残量が充電終了を表す値となったか否かを判定し、該判定が否定された場合にはステップ１００に戻って上述の処理が繰り返され、ステップ１０８の判定が肯定されたところで一連の処理を終了する。   In step 108, it is determined by the control unit 36 whether or not charging is completed. The determination is made by charging the charge control unit 32 while monitoring the remaining amount of the storage battery 30 and outputting the power monitoring result to the control unit 36. The control unit 36 sets the value indicating that the remaining amount of the storage battery 30 is charged. When the determination is negative, the process returns to step 100 and the above-described processing is repeated. When the determination at step 108 is affirmed, the series of processing ends.

すなわち、冬季などの寒い季節の場合には、蓄電池３０の温度が低く蓄電池３０が不活性状態となり、本格充電時の電流を蓄電池３０に供給しても充分な充電ができず、無駄な電力を消費してしまう。そこで、本実施形態では、蓄電池３０の温度を検出し、所定温度以下の場合には、予備充電を行なうことで、蓄電池３０を昇温して活性化させる。このとき、本格充電時の電流より小さい微小電流を蓄電池３０に供給することで予備充電が行なわれるので、微小電流によって蓄電池３０が昇温されて徐々に活性化される。また、微少電流を蓄電池３０に供給するので、蓄電池３０が不活性状態のときに熱に変わってロスされる電力も少なく、効率的な充電が可能となる。そして、予備充電によって蓄電池３０が昇温されると、ステップ１０２の判定が否定されて、続いて本格充電へ移行し、蓄電池３０が活性化した状態で充電を行なうことができる。従って、このように蓄電池３０の充電制御を行なうことによって、無駄な電力を消費することなく効率的に蓄電池３０を充電することができる。

Consume. Therefore, in the present embodiment, the temperature of the storage battery 30 is detected, and when the temperature is equal to or lower than the predetermined temperature, the storage battery 30 is heated and activated by performing preliminary charging. At this time, since the preliminary charging is performed by supplying the storage battery 30 with a minute current smaller than the current at the time of full charge, the storage battery 30 is heated by the minute current and gradually activated. In addition, since a minute current is supplied to the storage battery 30, when the storage battery 30 is in an inactive state, less power is lost instead of heat, and efficient charging is possible. When the temperature of the storage battery 30 is increased due to the preliminary charging, the determination in step 102 is denied, and then the process shifts to full-scale charging so that the storage battery 30 can be charged in an activated state. Therefore, by performing charging control of the storage battery 30 as described above, the storage battery 30 can be efficiently charged without consuming unnecessary power.

続いて、本発明の第５実施形態に係わる建物について説明する。図８は、本発明の第５実施形態に係わる建物の概略構成を示す図である。 In the present embodiment, the tap water always flows to the heat exchanger 58. However, the present invention is not limited to this. For example, a valve that can be driven by an actuator or the like is provided to cool the storage battery 30. It is good also as a structure which flows a tap water into the heat exchanger 58 only in the case.
(Fifth embodiment)
Then, the building concerning 5th Embodiment of this invention is demonstrated. FIG. 8 is a diagram showing a schematic configuration of a building according to the fifth embodiment of the present invention.

本発明の第５実施形態に係わる建物は、第４実施形態の変形例であり、電気温水器２０を利用して、蓄電池３０の温度調整を可能にしたものである。   A building according to the fifth embodiment of the present invention is a modification of the fourth embodiment, and enables the temperature adjustment of the storage battery 30 using the electric water heater 20.

具体的には、本実施形態では、電気温水器２０に水道水を供給する配管６０上に冷却用熱交換器６２を設けると共に、電気温水器２０によって生成された温水が流れ、住宅へ供給する温水配管６４上に昇温用熱交換器６６を設け、各熱交換器の近傍に蓄電池３０を配置する。配管６０には、冷却用熱交換器６２をバイパスするバイパス配管６０ａが接続され、温水配管６４には、昇温用熱交換器６６をバイパスする温水バイパス配管６４ａが接続される。   Specifically, in this embodiment, while providing the heat exchanger 62 for cooling on the piping 60 which supplies tap water to the electric water heater 20, the hot water produced | generated by the electric water heater 20 flows, and supplies it to a house. A temperature increase heat exchanger 66 is provided on the hot water pipe 64, and the storage battery 30 is disposed in the vicinity of each heat exchanger. A bypass pipe 60 a that bypasses the heat exchanger 62 for cooling is connected to the pipe 60, and a hot water bypass pipe 64 a that bypasses the heat exchanger 66 for temperature increase is connected to the hot water pipe 64.

また、冷却用熱交換器６２を介して電気温水器２０へ水道水を供給するか、冷却用熱交換器６２を介さずに電気温水器２０へ水道水を供給するかを切換える冷却用バルブ６８が設けられている。同様に、昇温用熱交換器６６を介して温水を住宅へ供給するか、昇温用熱交換器６６を介さずに温水を住宅へ供給するかを切換える昇温用バルブ７０が設けられている。冷却用バルブ６８及び昇温用バルブ７０は、アクチュエータ等によって駆動可能とされている。   Further, a cooling valve 68 that switches between supplying tap water to the electric water heater 20 via the cooling heat exchanger 62 or supplying tap water to the electric water heater 20 without passing through the cooling heat exchanger 62. Is provided. Similarly, a temperature raising valve 70 is provided for switching whether to supply hot water to the house via the temperature raising heat exchanger 66 or to supply hot water to the house without going through the temperature raising heat exchanger 66. Yes. The cooling valve 68 and the temperature raising valve 70 can be driven by an actuator or the like.

すなわち、冷却用熱交換器６２によって蓄電池３０を冷却することが可能とされ、かつ昇温用熱交換器６６によって蓄電池を昇温することが可能とされている。   That is, the storage battery 30 can be cooled by the cooling heat exchanger 62, and the storage battery can be heated by the temperature raising heat exchanger 66.

なお、昇温用熱交換器６６によって損失される温水の熱量が大きい場合には、電気温水器２０で温水を再度昇温するようにしてもよい。   When the amount of heat of the hot water lost by the temperature raising heat exchanger 66 is large, the temperature of the hot water may be raised again by the electric water heater 20.

図９は、本発明の第５実施形態に係わる建物の制御系の構成を示すブロック図である。本実施形態では、第１実施形態に対して、制御部３６に冷却用バルブ６８及び昇温用バルブ７０が接続されている点が相違する以外は、第１実施形態と同一構成であるため、相違点のみ説明する。   FIG. 9 is a block diagram showing a configuration of a building control system according to the fifth embodiment of the present invention. The present embodiment is the same as the first embodiment except that the cooling valve 68 and the temperature raising valve 70 are connected to the control unit 36 with respect to the first embodiment. Only the differences will be described.

制御部３６は、温度センサ３８の検出結果が所定温度以下で予備充電を行なう際に、昇温用バルブ７０を制御して、昇温用熱交換器６６によって蓄電池３０を昇温するように制御すると共に、温度センサ３８の検出結果が予め定めた温度以上になった場合には、冷却用バルブ６８を制御して、冷却用熱交換器６２によって蓄電池３０を冷却するように制御するようになっている。なお、蓄電池３０が所定温度以下の場合に予備充電を行なわずに、昇温用熱交換器６６だけで蓄電池３０を昇温するようにしてもよい。   The controller 36 controls the temperature raising valve 70 to control the temperature rise of the storage battery 30 by the temperature raising heat exchanger 66 when the preliminary charging is performed when the detection result of the temperature sensor 38 is equal to or lower than a predetermined temperature. At the same time, when the detection result of the temperature sensor 38 is equal to or higher than a predetermined temperature, the cooling valve 68 is controlled so that the storage battery 30 is cooled by the cooling heat exchanger 62. ing. In addition, when the storage battery 30 is below a predetermined temperature, the storage battery 30 may be heated only by the temperature raising heat exchanger 66 without performing preliminary charging.

以上のように構成された本発明の第５実施形態に係わる建物では、第１実施形態のように、温度が所定温度以下で予備充電を行なう際に、昇温用バルブ７０を制御して昇温用熱交換器６６に温水を流すことで、蓄電池３０を昇温することができ、第１実施形態よりも予備充電時間を短くすることができ、効率的に蓄電池３０を充電することができる。   In the building according to the fifth embodiment of the present invention configured as described above, the temperature rise valve 70 is controlled and controlled when precharging is performed at a temperature below a predetermined temperature as in the first embodiment. By flowing warm water through the heat exchanger 66 for warming, the temperature of the storage battery 30 can be raised, the precharging time can be shortened compared to the first embodiment, and the storage battery 30 can be charged efficiently. .

また、蓄電池３０が加熱して予め定められた温度以上になった場合に、制御部３６が冷却用バルブ６８を制御して冷却用熱交換器６２に水道水を流すことで、蓄電池３０を冷却することができる。   In addition, when the storage battery 30 is heated to a predetermined temperature or higher, the control unit 36 controls the cooling valve 68 to flow tap water to the cooling heat exchanger 62, thereby cooling the storage battery 30. can do.

従って、本実施形態では、蓄電池３０の温度を充電に適する温度に維持することができ、効率的な充電が可能となる。   Therefore, in this embodiment, the temperature of the storage battery 30 can be maintained at a temperature suitable for charging, and efficient charging becomes possible.

なお、上記の各実施形態では、建物に設けられた蓄電池３０を充電する際に、蓄電池３０の温度が低い場合に予備充電を行なってから本格的に充電するようにしたが、これに限るものではなく、自動車２８に搭載された走行用蓄電池２６を充電する際に同じように、蓄電池３０の温度が所定温度以下の場合に、予備充電によって走行用蓄電池３０を昇温してから本格充電するようにしてもよい。この場合には、走行用蓄電池２６の温度の検出結果を自動車２８から取得する必要があるので、走行用蓄電池３６の代りに外気温を検出するようにしてもよい。   In each of the above embodiments, when charging the storage battery 30 provided in the building, if the temperature of the storage battery 30 is low, preliminary charging is performed and then charging is performed in earnest. Instead, when charging the storage battery 26 mounted on the vehicle 28, when the temperature of the storage battery 30 is equal to or lower than a predetermined temperature, the storage battery 30 is heated up by preliminary charging and then fully charged. You may do it. In this case, since the detection result of the temperature of the traveling storage battery 26 needs to be acquired from the automobile 28, the outside air temperature may be detected instead of the traveling storage battery 36.
