Description

本発明はバッテリーに充電する充電装置に関するものである。The present invention relates to a charging device for charging a battery.

従来から電気料金が安い夜間の時間帯に自動的にバッテリーに充電する充電装置があった。Conventionally, there has been a charging device that automatically charges the battery during night hours when electricity charges are cheap.

電気料金が安くなり始める時間に自動的に充電が始まるようにタイマーが作動する場合、電気料金が安い夜間の時間帯に充電すべきすべての電気を充電しきれない場合があった。一方、前記タイマーを使わない場合電気料金が安くなる前に充電を始めたにもかかわらず、電気料金が安い時間帯がまだ残っている時点において充電が終了してしまう場合があった。When the timer is activated so that charging starts automatically at the time when the electricity charge starts to be cheap, there is a case where not all electricity to be charged can be charged at night time when the electricity charge is low. On the other hand, in the case where the timer is not used, charging may end at a point in time when the time period when the electricity charge is low still remains even though the charging is started before the electricity charge is reduced.

本発明は前記の課題を解決するために、バッテリーに充電する充電装置に、バッテリーの充電に必要な時間を計算する充電必要時間計算手段と、前記の充電必要時間を電気料金が安い順の各充電時間帯に配分する充電時間配分計算手段と、充電時間配分計算手段の計算結果に応じて充電時間を調整するためのスイッチを設けている、ことを特徴としている。In order to solve the above-described problems, the present invention provides a charging device for charging a battery, charging time calculation means for calculating the time required for charging the battery, and the charging time for each of the charging times in the order of cheaper electricity charges. Charging time distribution calculating means for allocating to the charging time zone and a switch for adjusting the charging time according to the calculation result of the charging time distribution calculating means are provided.

これによって電気料金が安くなり始める前に充電を始める手続きを行った場合であっても、電気料金が最も安い時間帯に最も多くの充電時間が自動的に割り振られるため電気料金を最も節約することが可能となる。また、電力系統における電力負荷の平準化にも貢献する。Even if the procedure to start charging before the electricity price starts to be reduced by this, the most charging time is automatically allocated in the hour when the electricity price is the cheapest, so the electricity cost can be saved the most Is possible. It also contributes to leveling the power load in the power system.

本発明による充電装置の一実施形態の構成を図３に示すブロック図に基づいて説明する。電動自動車の所有者が夕方に帰宅後、電動自動車１に搭載されたバッテリー２に充電するための手動スイッチ３をオンにする（１８時）。バッテリー２の残りの充電容量を検知する残量センサー４から送信された情報を踏まえて、充電必要時間計算手段５が充電に必要な時間（たとえば１１時間）を算出する。充電必要時間計算手段５から送信された充電必要時間（１１時間）と、手動スイッチ３がオンにされた時間（１８時）の情報を踏まえて、充電時間配分計算手段６が充電必要時間（１１時間）を電気料金が最も安い夜間の８時間（２３時〜翌日７時）とその前の３時間（２０時〜２３時）に分ける時間配分を算出する。制御部８から２０時に送られる信号を踏まえてスイッチ７が２０時に自動的にオンになる。２０時に充電が開始されたあと１１時間充電され、翌朝７時に自動的に充電が終了する。その結果、電気料金が最も安い夜間電力が最大限使用されるので、電気代が節約される。また、夜間電力が最大限使用される結果、電力系統における電力負荷の平準化に貢献する。A configuration of an embodiment of a charging device according to the present invention will be described based on a block diagram shown in FIG. After the owner of the electric vehicle returns home in the evening, the manual switch 3 for charging the battery 2 mounted on the electric vehicle 1 is turned on (18:00). Based on the information transmitted from the remaining amount sensor 4 that detects the remaining charge capacity of the battery 2, the required charge time calculation means 5 calculates the time required for charging (for example, 11 hours). Based on the information on the required charging time (11 hours) transmitted from the required charging time calculating means 5 and the time when the manual switch 3 is turned on (18:00), the charging time distribution calculating means 6 determines the required charging time (11 Time distribution is divided into 8 hours (23:00 to 7:00 on the next day) and the previous 3 hours (20:00 to 23:00) at the night when the electricity rate is the cheapest. Based on a signal sent from the control unit 8 at 20:00, the switch 7 is automatically turned on at 20:00. After charging starts at 20:00, it is charged for 11 hours, and then automatically ends at 7am the next morning. As a result, the electricity cost is saved because the nighttime electricity with the lowest electricity charge is used to the maximum. In addition, as a result of maximum use of nighttime power, it contributes to leveling of the power load in the power system.

なお、前記の夜間の時間帯の前の３時間は、たとえば１８時〜２１時などであってもよい。The three hours before the night time period may be, for example, from 18:00 to 21:00.

また、翌朝電動自動車を利用する際などに充電終了時間を充電時間配分計算手段６に送信することにより、たとえば前記充電必要時間（１１時間）を電気料金が安い夜間の７時間（２３時〜翌日６時）とその前の４時間（１９時〜２３時）などにわけて配分してもよい。In addition, when the electric vehicle is used the next morning, the charging end time is transmitted to the charging time distribution calculating means 6 so that, for example, the required charging time (11 hours) is reduced to 7 hours (from 23:00 to the next day) at night when electricity charges are low. 6 o'clock) and the previous 4 hours (19: 00-23: 00), etc.

また、前記の実施形態はバッテリー２と残量センサー４のみ電動自動車に搭載しているが、手動スイッチ３や充電必要時間計算手段５や充電時間配分計算手段６やスイッチ７なども電動自動車に搭載してもよい。また、それらの全てが電動自動車に搭載されなくてもよい。In the above embodiment, only the battery 2 and the remaining amount sensor 4 are mounted on the electric vehicle. However, the manual switch 3, the charging time calculation means 5, the charging time distribution calculation means 6, the switch 7 and the like are also mounted on the electric vehicle. May be. Moreover, not all of them need be mounted on the electric vehicle.

また、前記の実施形態における手動スイッチ３の代わりにプラグやコンセントでもよい。Further, a plug or an outlet may be used instead of the manual switch 3 in the above embodiment.

次に前記の一実施形態における動作例を、図３に示すフローチャートに基づいて説明する。電動自動車の所有者が夕方に帰宅後、電動自動車１に搭載されたバッテリー２に充電するための手動スイッチ３を１８時の時点でオンにする（ステップ１）。バッテリー２の残りの充電容量を検知する残量センサー４から送られた情報に基づき充電必要時間計算手段５が算出した充電必要時間が１１時間であるとする。充電時間配分計算手段６は充電必要時間計算手段５から送られた充電必要時間と、電気料金が最も安い夜間電気料金が適用される夜間電力時間の長さを比較する（スッテプ２）。充電必要時間の１１時間が夜間電力時間の８時間よりも長いので、充電時間配分計算手段６が充電時間の１１時間を夜間電力時間の８時間とその前の３時間に配分して、夜間電力時間が始まる２３時の３時間前の２０時に制御部８からスイッチをオンにする信号が送られてスイッチ７がオンになる（ステップ３）。１１時間の充電時間が経過して夜間電力時間の終了と同時に充電が終了する翌朝の７時に制御部８からスイッチをオフにする信号が送られてスイッチ７がオフになる（ステップ４）。ステップ１で手動スイッチ３がオンでないとスイッチ７はオフのままである（ステップ５）。ステップ２で充電必要時間が夜間電力時間よりも短い場合は、充電時間がすべて夜間電力時間に配分されて、夜間電力時間の終了時から充電必要時間を引いた時間より前の時点で制御部８からスイッチをオンにする信号が送られてスイッチ７がオンになる（ステップ６）スッテプ６を経て充電が開始された場合、充電必要時間が経過して充電が終了した時点で制御部８からスイッチをオフにする信号が送られてスイッチ７がオフになる（ステップ７）。なお、前記スッテプ３で充電時間配分計算手段６が用いた充電開始時間を算出するための算式の例は、充電開始時間＝夜間電力開始時間−（充電必要時間−夜間電力時間）である。Next, an operation example in the embodiment will be described based on a flowchart shown in FIG. After the owner of the electric vehicle returns home in the evening, the manual switch 3 for charging the battery 2 mounted on the electric vehicle 1 is turned on at 18 o'clock (step 1). It is assumed that the required charging time calculated by the required charging time calculation means 5 based on the information sent from the remaining amount sensor 4 that detects the remaining charging capacity of the battery 2 is 11 hours. The charging time distribution calculating means 6 compares the required charging time sent from the required charging time calculating means 5 with the length of the night electric power time to which the night electricity charge with the lowest electricity charge is applied (Step 2). Since 11 hours of charging time is longer than 8 hours of night power time, the charging time distribution calculating means 6 distributes 11 hours of charging time to 8 hours of night power time and 3 hours before it, A signal for turning on the switch is sent from the control unit 8 at 20:00, 3 hours before 23:00 when the time starts, and the switch 7 is turned on (step 3). A signal to turn off the switch is sent from the control unit 8 at 7 o'clock in the morning when charging is completed at the same time as the end of the night electric power time after 11 hours of charging time, and the switch 7 is turned off (step 4). If the manual switch 3 is not turned on in step 1, the switch 7 remains off (step 5). If the required charging time is shorter than the nighttime power time in step 2, the charging time is allotted to the nighttime power time, and the control unit 8 at a time before the time required for charging is subtracted from the end of the nighttime power time. The switch 7 is turned on when a signal for turning on the switch is sent from (Step 6). When charging is started through Step 6, the switch from the control unit 8 is switched when charging is completed after the required charging time elapses. Is sent to turn off the switch 7 (step 7). An example of a formula for calculating the charging start time used by the charging time distribution calculating means 6 in step 3 is charging start time = night power start time− (required charge time−night power time).
