- the power storage unit 12 may be discharged to supply power.
- the power storage unit 12 when the time for performing the charging operation of the charging unit 11 is changed ahead of the reference time, the power storage unit 12 is discharged at a predetermined time after the charging operation of the charging unit 11 is started as shown in FIG. In the case of changing the time backward, the power storage unit 12 may be discharged at a predetermined time before the charging operation of the charging unit 11 ends.
- the charging unit 11 performs charging for consuming system power and charging for consuming power supplied by discharging the power storage unit 12, but includes a case where charging is performed simultaneously. It doesn't matter. Specifically, for example, in charging from 12:15 to 12:35 in FIG. 7, instead of the power storage unit 12 supplying power from 12:15 to 12:20, 1/3 of the power is supplied to 12 It may be distributed and supplied from 15 minutes to 12:30 hours.
- the rear unit time in the example of FIG. 8, from 12:30 to 13:00, from 13:30 to 14:00 0 minutes
- the amount of grid power consumed by the charging unit 11 can be reduced. Therefore, you may charge the electrical storage part 12 with system
- the power storage unit 12 may be charged with the system power in the unit time ahead.
- the time shown in FIGS. 5 and 7 is measured with a clock attached to a power meter or the like installed by the electric power company, and there may be a deviation from the actual time. Due to the deviation, for example, the unit time is preferably 10 to 40 minutes and 40 to 10 minutes per hour in actual time. In this case, the start time of the reference time can be set to 0 minutes (or 30 minutes). For this reason, it is possible to set a charging time that is clear and easy for the user to remember.
- the magnitude of the power consumed when the charging unit 11 performs the charging operation is constant regardless of the time, but may not be constant.
- the intermediate time of the charging operation by the charging unit 11 is set to two unit times. It may be set so as to be shifted from the time that becomes the boundary of. Even in this case, in order to simplify the control of the charging unit 11 by the control unit 15, the intermediate time of one charging operation of the charging unit 11 and the time at the boundary between two unit times are substantially equal. You may set as follows.
- part or all of the operations of the control unit 15 and the like may be performed by a control device such as a microcomputer. Further, all or part of the functions realized by such a control device are described as a program, and the program is executed on a program execution device (for example, a computer) to realize all or part of the functions. It doesn't matter if you do.
- the charging system 1 shown in FIG. 1 can be realized by hardware or a combination of hardware and software.
- achieved by software shall represent the functional block of the site
- the present invention can be used in a charging system that charges a battery or the like provided in an electric vehicle.
- the present invention is suitable when applied to a charging system that can perform rapid charging in which power consumption is large and charging is performed within a unit time or less.

Abstract
Description
図1は、本発明の実施の一形態である充電システムの構成例を示すブロック図である。なお、図中の各ブロックを接続する実線の矢印は電力のやり取りを示し、破線の矢印は情報のやり取りを示している。
次に、系統電力の電力料金の算出方法の一例について、図面を参照して説明する。図2は、系統電力の電力料金の算出方法の概要を示すグラフである。なお、図2に示すグラフは、12時0分~12時30分、12時30分~13時0分、13時0分~13時30分及び13時30分~14時0分のそれぞれの単位時間(毎時0分~30分及び30分~0分のそれぞれの30分間)において、充電システム1を備える店舗等の全体で消費された系統電力の電力量を、グラフの高さとして示したものである。
上述のように、単位時間に消費される系統電力の電力量の最大値を低減することで、電力料金(特に、基本料金。以下同じ。)を低減することができる。以下、単位時間に消費される系統電力の電力量の最大値を低減するための充電スケジュール(制御部15による充電部11の充電動作の制御方法)について、図面を参照して説明する。まず、比較のために、図3及び図4を参照して、充電部11の充電動作の好ましくない制御方法について説明する。
本発明の実施形態における充電システム1について、制御部15などの一部または全部の動作を、マイコンなどの制御装置が行うこととしても構わない。さらに、このような制御装置によって実現される機能の全部または一部をプログラムとして記述し、該プログラムをプログラム実行装置(例えばコンピュータ)上で実行することによって、その機能の全部または一部を実現するようにしても構わない。
