- the power generation voltage of the solar cell module may be monitored by a microcomputer or the like. Then, the process proceeds to step S13.
- step S13 the PV charger 20 supplies power to the input / output unit 21.
- the EMU 27 and the BMU 28 connected to the input / output unit 21 are activated.
- step S14 the power storage unit 29 is connected to the system of the power storage device 10 as the BMU 28 operates.
- step S15 the process proceeds to step S15.
- step S15 it is determined whether or not it is necessary to supply power to the load 4. This determination is made by the EMU 27, for example. If it is necessary to supply power to the load 4, the process proceeds to step S16. If it is not necessary to supply power to the load 4, the process proceeds to step S17.
- step S16 processing in the normal charge / discharge mode is performed.
- the normal charge / discharge mode is, for example, a mode in which charge / discharge is performed by an arbitrary method. That is, in this mode, the power supplied from the solar cell module may be supplied to the load 4, or the power of the power storage unit 29 may be supplied to the load 4. Further, the power supplied from the AC power supply unit 3 may be supplied to the load 4 while charging the power storage unit 29 with the power supplied from the solar cell module.
- step S17 the electric power formed by the PV charger 20 is supplied to the power storage unit 29 via the input / output unit 21 and the BMU 28. Thereby, the power storage unit 29 is charged. Then, the process proceeds to step S18.
- step S18 it is determined whether or not the power generation voltage V of the solar cell module is equal to or higher than a threshold value Vstop.
- the threshold value Vstop is set to 90V, for example. If the power generation voltage V of the solar cell module is equal to or higher than the threshold value Vstop, the process proceeds to step S19. If the power generation voltage V of the solar cell module is smaller than the threshold value Vstop, the process proceeds to step S21.
- step S19 it is determined whether or not it is necessary to supply power to the load 4. This determination is made by the EMU 27, for example. If it is necessary to supply power to the load 4, the process proceeds to step S16. As described above, in step S16, processing in the normal charge / discharge mode is performed.
- step S20 it is determined whether or not the SOC (StateSOOf Charge) of power storage unit 29 is equal to or greater than threshold SOCmax. This determination is made by the EMU 27 based on information transmitted from the BMU 28, for example.
- the threshold value SOCmax is set to 100%, for example. Note that a determination using DOD (DepthDOf Discharge) instead of the SOC may be made in the determination in step S20.
- DOD DepthDOf Discharge
- step S21 charging is stopped because the capacity of the power storage unit 29 has increased. Then, the process proceeds to step S22.
- step S22 it is determined whether or not the power generation voltage V of the solar cell module is equal to or higher than a threshold value Vstop. If the generated voltage V of the solar cell module is equal to or higher than the threshold value Vstop, the process returns to step S20. Then, if the SOC is reduced in the determination in step S20, the process returns to step S17, and charging of power storage unit 29 is resumed. If the power generation voltage V of the solar cell module is smaller than the threshold value Vstop, the process proceeds to step S23.
- step S23 it is determined whether or not the decrease amount ⁇ SOC of the capacity of the power storage unit 29 is equal to or greater than the threshold value S%.
- the threshold value S% is set to 2%, for example. When the amount of decrease ⁇ SOC in the capacity of power storage unit 29 is smaller than the threshold value 2%, the process returns to step S22, and the determination in step S22 is performed. If the amount of decrease ⁇ SOC in the capacity of power storage unit 29 is equal to or greater than the threshold value 2%, the process proceeds to step S24.
- step S24 the power storage device 10 is shut down. That is, the EMU 27 of the power storage device 10 performs control to stop the operation of the BMU 28 and the like of the power storage device 10, and then turns itself off.
- the duration of the state where the PV power generation voltage is smaller than the threshold may be measured by a timer, and the power storage device 10 may be shut down when the measurement time has passed a predetermined time.
- the generated voltage of the solar cell module varies depending on the weather. For this reason, the control according to the power generation voltage of the solar cell module is performed without shutting down the power storage device 10 immediately after stopping the charging. When the generated voltage of the solar cell module is above a certain level and the capacity of the power storage unit decreases, charging is performed again.
- the power of the power storage unit is prevented from being consumed further by the operation of the EMU, Shut down the power storage device.
- the system of the power storage device is self-started to charge the power storage unit.

以下に説明する実施形態等は本開示の好適な具体例であり、本開示の内容がこれらの実施形態等に限定されるものではない。
「蓄電部の一例について」
本開示における蓄電装置は、蓄電部を有する。蓄電装置の説明に先立ち、蓄電部の一例について説明する。蓄電部は、例えば、複数の2次電池により構成される。蓄電部を構成する2次電池は、例えば、正極活物質と、黒鉛等の炭素材料を負極活物質として含むリチウムイオン2次電池である。正極材料として特に限定はないが、好ましくは、オリビン構造を有する正極活物質を含有するものである。
ンタフルオロエタンスルホニル)イミドリチウム(Li(C2F5SO2)2N)、過塩素酸リチウム(LiClO4)、六フッ化ヒ酸リチウム(LiAsF6)、四フッ化ホウ酸リチウム(LiBF4)、トリフルオロメタンスルホン酸リチウム(LiSO3CF3)、ビス(トリフルオロメタンスルホニル)イミドリチウム(Li(CF3SO2)2N)、トリス(トリフルオロメタンスルホニル)メチルリチウム(LiC(SO2CF3)3である。
本開示の理解を容易とするために、図1を参照して一般的な蓄電装置(蓄電システム)の構成について説明する。なお、図1から図7における実線の矢印は電力の流れを示す。蓄電装置内または蓄電装置と外部の機器との間では所定の規格に基づく通信が行われるが、通信に基づく信号の流れの図示は省略している。
図6は、本開示における蓄電装置(蓄電装置10)の構成の一例を示す。蓄電装置10において、蓄電装置1と同様の構成については同一の符号を付し、重複した説明を省略する。
蓄電装置10の起動処理の一例について、詳細に説明する。スイッチSW40がオンされることに応じて、蓄電部29の直流電力が電流生成部26に供給される。電流生成部26は、蓄電部29から供給される直流電力に基づいて、低レートの電流を生成する。この電流は、初期充電における低レートの充電電流と同じ1.0A程度の電流である。電流生成部26により生成された低レートの電流が入出力部21に供給される。
第2の実施形態における蓄電装置の構成および動作は、第1の実施形態における蓄電装置10と同様であるので重複した説明を省略する。第2の実施形態では、蓄電装置10がシャットダウンされている状態で外部から電力の供給がある場合に、蓄電装置10のシステムを自己起動し、蓄電部29を充電するようにしている。そして、外部から供給される電力が減少もしくは低下した場合には、蓄電装置10がシステムを自律的にシャットダウンし、待機電力を0にする。なお、第2の実施形態では、DC電源部2を太陽電池モジュールとして説明する。
第2の実施形態における蓄電装置10の処理の流れの一例について、図10のフローチャートを参照して説明する。ステップS10では、蓄電装置10がシャットダウンされている。すなわち、スイッチSW40がオフされ、蓄電部29が蓄電装置10内のシステムから切り離されている。上述したように、この状態における待機電力は0である。そして、処理がステップS11に進む。
以上、本開示の実施形態について具体的に説明したが、本開示は、上述の実施形態に限定されるものではなく各種の変形が可能である。
