Such an outlet 50 may be provided in the system of the embodiment. In the past, charging using an AC power supply was performed in this way. However, when using the system of this embodiment, a terminal for charging the storage battery 22 of the storage battery-equipped device with a direct current is provided at the fourth terminal. Is preferred. Alternatively, as described in Example 2 and below, the storage battery 22 of the storage battery mounted device may be removed from the storage battery mounted device and charged.

以上の回路は次のようにして使用する。
（１）第１充電回路３２により、自家発電電源装置１８の発電電力を自家用蓄電池２０に充電できる。この電力は、主として宅内配線１６側に供給されて使用される。自家用蓄電池２０に充電された電力は、夜間に蓄電池搭載機器の蓄電池２２の充電にも利用される。
（２）第２充電回路３４により、自家発電電源装置１８の発電電力を蓄電池搭載機器の蓄電池２２に充電できる。昼間に蓄電池搭載機器を接続できれば、この方法で充電ができる。

（４）第４充電回路３８により、廉価な夜間電力を利用して、電池搭載機器の蓄電池２２を充電できる。夜間に蓄電池搭載機器を接続できれば、この方法で充電ができる。 The above circuit is used as follows.
(1) The first charging circuit 32 can charge the private storage battery 20 with the power generated by the private power generation device 18. This electric power is mainly supplied to the home wiring 16 side and used. The electric power charged in the personal storage battery 20 is also used for charging the storage battery 22 of the storage battery mounted device at night.
(2) The second charging circuit 34 can charge the storage battery 22 of the storage battery-equipped device with the power generated by the private power generation power supply device 18. If a battery-equipped device can be connected in the daytime, it can be charged by this method.
(3) The third charging circuit 36 can charge the private storage battery 20 with inexpensive nighttime power. This is used when the power generated by the private power generator 18 is insufficient.
(4) The fourth charging circuit 38 can charge the storage battery 22 of the battery-equipped device using inexpensive nighttime power. If a battery-equipped device can be connected at night, it can be charged by this method.

（５）電気自動車が、昼間は戸外で使用され夜間にのみ駐車場に置かれることも多い。太陽光発電装置のような昼間に発電する装置の電力を自家用蓄電池２０に蓄積しておけば、上記のように、夜間にその電力を電気自動車に充電できる。
（６）電気自動車が、昼間にのみ駐車場に置かれるときは、廉価な夜間電力を自家用蓄電池２０に蓄積しておき、昼間にその電力を電気自動車に充電できる。
（７）上記のいずれかの方法を選択することにより、電池搭載機器の蓄電池２２の充電に、最も経済的な方法を採用できる。 (5) Electric vehicles are often used outdoors during the day and are often placed in parking lots at night. If the electric power of a device that generates electricity in the daytime, such as a solar power generation device, is stored in the private storage battery 20, the electric vehicle can be charged to the electric vehicle at night as described above.
(6) When an electric vehicle is placed in a parking lot only in the daytime, inexpensive nighttime electric power can be stored in the personal storage battery 20 and the electric vehicle can be charged in the daytime.
(7) By selecting any one of the above methods, the most economical method can be adopted for charging the storage battery 22 of the battery-equipped device.

（８）自家用蓄電池２０に充電された電力を住宅内で利用する場合、蓄電池搭載機器の蓄電池２２が接続されていれば、自家用蓄電池２０の充電電力と蓄電池搭載機器の蓄電池２２の充電電力との合計容量の電力を利用することが可能となり、より大きな経済効果を得ることができる。 (8) When the electric power charged in the personal storage battery 20 is used in a house, if the storage battery 22 of the storage battery mounted device is connected, the charging power of the storage battery 20 of the personal storage battery and the charging power of the storage battery 22 of the storage battery mounted device It becomes possible to use the power of the total capacity, and a greater economic effect can be obtained.

（９）第１充放電回路４４や第２充放電回路４６により、自家用蓄電池２０と電池搭載機器の蓄電池２２の充電量を融通して充電量の適正化を図れる。電池搭載機器の蓄電池２２を自家発電電源装置１８の電力を蓄積するために利用すれば、自家用蓄電池２０の負荷を軽減し、自家用蓄電池２０の寿命を伸ばすことができる。 (9) With the first charge / discharge circuit 44 and the second charge / discharge circuit 46, the charge amount of the storage battery 20 for personal use and the storage battery 22 of the battery-equipped device can be accommodated to optimize the charge amount. If the storage battery 22 of the battery-equipped device is used to store the electric power of the private power generation power supply 18, the load on the private storage battery 20 can be reduced and the life of the private storage battery 20 can be extended.

（１０）特に、蓄電池搭載機器が、長期間使用されないか、あるいは希にしか使用されない場合がある。このような場合に、蓄電池搭載機器の蓄電池２２を適度に使用すれば、その蓄電池２２の性能を維持できる。しかも、自然放電により充電量が適正値以下まで減少するのを防ぎ、例えば、蓄電池２２の適正最低充電量を３０％に設定して、蓄電池搭載機器をいつでも使用できる状態にしておくことができる。 (10) In particular, the storage battery mounted device may not be used for a long time or may be used rarely. In such a case, if the storage battery 22 of the storage battery mounted device is used appropriately, the performance of the storage battery 22 can be maintained. Moreover, it is possible to prevent the charge amount from being reduced to an appropriate value or less due to natural discharge, and for example, the appropriate minimum charge amount of the storage battery 22 can be set to 30% so that the storage battery mounted device can be used anytime.

図３は実施例２の充電回路例を示す結線図である。
例えば、太陽電池の場合、多数のセル群を必要な数だけ直列接続して、要求される出力電圧を得ることができる。従って、蓄電池を充電するための最適な直流出力電圧を直接取り出すことも可能である。この場合には、直流電圧を昇圧したり、降圧したりする回路は必要としない。例えば第１充電回路３２と第２充電回路３４は、充電電圧や充電電流をモニタしながら出力電流を断続するスイッチング回路等であればよい。この実施例では、第１充電回路３２と第２充電回路３４とを一体化した例を示した。 FIG. 3 is a connection diagram illustrating an example of a charging circuit according to the second embodiment.
For example, in the case of a solar cell, a required output voltage can be obtained by connecting as many cell groups as necessary in series. Therefore, it is possible to directly take out the optimum DC output voltage for charging the storage battery. In this case, a circuit for boosting or lowering the DC voltage is not required. For example, the first charging circuit 32 and the second charging circuit 34 may be switching circuits or the like that intermittently output current while monitoring the charging voltage and charging current. In this embodiment, an example in which the first charging circuit 32 and the second charging circuit 34 are integrated is shown.

図の例では、自家用蓄電池２０と蓄電池搭載機器の蓄電池２２に、充電量適正化回路６０と充電器性能判定回路６２とを接続した。一般に、蓄電池の充電では、例えば、蓄電量が少ない状態で定電流制御をし、端子電圧上昇後に定電圧制御に切り替えるといった制御を行う。充電量適正化回路６０がこの役割を果たす。これにより、充電量の適正化が図れる。同時に、充電器性能判定回路６２は、充放電特性を監視して、蓄電池の充電性能を判定する。なお、この実施例では、蓄電池搭載機器の蓄電池２２を蓄電池搭載機器から取り外して充電をするようにしている。これにより、自家発電電源装置１８から自家用蓄電池２０への充電と、自家発電電源装置１８から蓄電池搭載機器の蓄電池２２への充電を自由に制御できる。   In the example of the figure, the charge amount optimization circuit 60 and the charger performance determination circuit 62 are connected to the private storage battery 20 and the storage battery 22 of the storage battery mounted device. In general, in charging a storage battery, for example, control is performed such that constant current control is performed in a state where the amount of stored power is small, and switching to constant voltage control is performed after the terminal voltage rises. The charge amount optimization circuit 60 plays this role. Thereby, optimization of charge amount can be achieved. At the same time, the charger performance determination circuit 62 monitors the charge / discharge characteristics to determine the charge performance of the storage battery. In this embodiment, the storage battery 22 of the storage battery mounted device is removed from the storage battery mounted device for charging. Thereby, the charge to the storage battery 20 for private use from the private power generation power supply device 18 and the charge to the storage battery 22 of the storage battery mounted device from the private power generation power supply device 18 can be freely controlled.

図のように、第３端子２８と第４端子３０の間に第１充放電回路４４を設けることにより、昼間に自家発電電源装置１８を用いて自家用蓄電池２０に充電した電力を、蓄電池搭載機器の蓄電池２２に送って充電をすることができる。一方、例えば、長期間蓄電池搭載機器を使用する予定がない場合がある。このときは、蓄電池搭載機器の蓄電池２２に対して、その性能を維持できる最小限の電力のみを充電しておくことが好ましい。余分な電力が充電されていれば、その電力を自家用蓄電池２０に移して有効に利用する。このために、第３端子２８と第４端子３０の間に第２充放電回路４６を設けた。即ち、自家用蓄電池２０と蓄電池２２の充電量を適当に融通することができる。   As shown in the figure, by providing the first charging / discharging circuit 44 between the third terminal 28 and the fourth terminal 30, the electric power charged in the personal storage battery 20 using the private power generation device 18 in the daytime is stored in the storage battery. The battery can be sent to the storage battery 22 for charging. On the other hand, for example, there are cases where there is no plan to use a storage battery-equipped device for a long time. At this time, it is preferable to charge only the minimum electric power which can maintain the performance with respect to the storage battery 22 of a storage battery mounting apparatus. If the excess power is charged, the power is transferred to the personal storage battery 20 for effective use. For this purpose, a second charge / discharge circuit 46 is provided between the third terminal 28 and the fourth terminal 30. That is, the charge amount of the private storage battery 20 and the storage battery 22 can be appropriately accommodated.

例えば、充電量適正化回路６０は適正最大充電量を８０％とか９０％に設定して、蓄電池の長寿命化を図ることができる。また、例えば、蓄電池搭載機器の蓄電池２２の適正最低充電量を３０％と設定しておく。これにより、宅内への電力供給のために充放電を行なったとしても、適正最低充電量３０％以上は放電しないで維持しておくことができる。これにより、蓄電池搭載機器の突然の使用要求に応えることができる。事前に使用予定が分かっていれば、蓄電池搭載機器の蓄電池２２をフル充電しておくとよい。   For example, the charge amount optimization circuit 60 can set the appropriate maximum charge amount to 80% or 90% to extend the life of the storage battery. For example, the appropriate minimum charge amount of the storage battery 22 of the storage battery mounted device is set to 30%. Thereby, even if it charges / discharges for the electric power supply to a house, the appropriate minimum charge amount 30% or more can be maintained without discharging. Thereby, it can respond to the sudden use demand of storage battery equipment. If the use schedule is known in advance, the storage battery 22 of the storage battery mounted device may be fully charged.

図４は、コンピュータによる充電量制御のための回路結線図である。
上記のような自家用蓄電池２０と蓄電池搭載機器の蓄電池２２の充放電量の適正な融通制御は、コンピュータにより自動化することができる。また、利用者がコンピュータを使用して充電量を設定できる。その場合には、図１に示した回路群を、例えば、ＨＥＭＳ（ホームエネルギマネージメントサービス）サーバ６４に接続して制御するとよい。 FIG. 4 is a circuit connection diagram for charge amount control by a computer.
The appropriate interchange control of the charge / discharge amount of the private storage battery 20 and the storage battery 22 of the storage battery mounted device as described above can be automated by a computer. In addition, the user can set the amount of charge using a computer. In that case, the circuit group shown in FIG. 1 may be connected to, for example, a HEMS (Home Energy Management Service) server 64 and controlled.

ＨＥＭＳサーバ６４は、一般住宅等の建物内部のエネルギ供給量とエネルギ消費量とを詳細にモニタして、その結果をディスプレイ６６に表示したり、例えば、エアコンの運転を制御して、適正温度に制御するといった機能を持つ。このＨＥＭＳサーバ６４に、自家用蓄電池２０と蓄電池搭載機器の蓄電池２２の適正最大充電量や適正最低充電量を計算する機能等を付与するとよい。なお、本発明において、ＨＥＭＳサーバ６４は、少なくとも、建物内の指定されたエネルギ使用機器の状態とエネルギ供給状態を取得する機能があればよく、例えば、エネルギ使用機器として、蓄電池を指定し、エネルギ供給状態として、送配電線路からの受電出電力と自家発電装置の発電電力を指定すれば、以下のシステムが実現する。   The HEMS server 64 monitors in detail the energy supply amount and energy consumption amount in a building such as a general house, and displays the result on the display 66, or controls the operation of an air conditioner, for example, to obtain an appropriate temperature. It has a function to control. The HEMS server 64 may be provided with a function for calculating an appropriate maximum charge amount and an appropriate minimum charge amount of the storage battery 20 for personal use and the storage battery 22 of the storage battery mounted device. In the present invention, the HEMS server 64 only needs to have at least a function of acquiring the state and energy supply state of the designated energy use device in the building. For example, the HEMS server 64 designates a storage battery as the energy use device, If the received power from the transmission and distribution line and the generated power of the private power generator are specified as the supply state, the following system is realized.

図４には、図１に示した各回路に図３で説明した充電量適正化回路６０と充電器性能判定回路６２とを設けた例を示す。第２充電回路以下にも、第１充電回路と同様に充電量適正化回路６０と充電器性能判定回路６２とを追加する。図４ではそれらの図示を省略した。   FIG. 4 shows an example in which the charge amount optimization circuit 60 and the charger performance determination circuit 62 described in FIG. 3 are provided in each circuit shown in FIG. The charge amount optimizing circuit 60 and the charger performance determining circuit 62 are added to the second charging circuit and the like as well as the first charging circuit. In FIG. 4, these illustrations are omitted.

例えば、図４の例では、ディスプレイ６６に表示された制御画面により、例えば、蓄電池搭載機器の蓄電池２２の適正最大充電量を９０％とし、最低充電量を３０％に設定する。この設定は、各回路の充電量適正化回路６０に通知される。従って、蓄電池搭載機器の蓄電池２２を商用電源で充電する場合も、自家発電電源装置１８で充電する場合も、自家用蓄電池２０で充電する場合も、フル充電の場合には９０％まで充電する。また、蓄電池搭載機器の蓄電池２２の電力を宅内配線に放電する場合には、充電量が３０％になると、放電を停止するように制御する。   For example, in the example of FIG. 4, the appropriate maximum charge amount of the storage battery 22 of the storage battery mounted device is set to 90% and the minimum charge amount is set to 30%, for example, by the control screen displayed on the display 66. This setting is notified to the charge amount optimization circuit 60 of each circuit. Therefore, in the case of charging the storage battery 22 of the storage battery-equipped device with a commercial power supply, charging with the private power generation power supply device 18, charging with the private storage battery 20, charging up to 90% in the case of full charge. Further, when the power of the storage battery 22 of the storage battery mounted device is discharged to the home wiring, the control is performed so that the discharge is stopped when the charge amount becomes 30%.

このほかに、任意のタイミングで、自家用蓄電池２０と蓄電池搭載機器の蓄電池２２を充電したり、これらを放電させたり、これらのうちの一方で他方を充電したりする制御信号を、ＨＥＭＳサーバ６４から送出させるとよい。これにより、建物内部の総合的なエネルギ管理に自家用蓄電池２０と蓄電池搭載機器の蓄電池２２を役立てることができる。   In addition, a control signal for charging the private storage battery 20 and the storage battery 22 of the storage battery mounted device, discharging them, or charging one of them at any time is sent from the HEMS server 64 at any timing. Send it out. Thereby, the storage battery 20 for private use and the storage battery 22 of a storage battery mounting apparatus can be used for the comprehensive energy management inside a building.
