Description

電動移動体のバッテリ管理装置Battery management device for electric vehicles
　本発明は、電動移動体のバッテリ管理装置に関するものである。 The present invention relates to a battery management device for an electric vehicle.
　電動車両（ＥＶ：Electric Vehicle）などの電動移動体は、制御装置（ＶＣＵ：Vehicle Control Unit）によって、モータ、インバータ、バッテリ、空調装置など、相互に影響し合う各コンポーネントの動作が制御されている。ＶＣＵによって制御されるコンポーネントの中で、電動移動体の動作源となるバッテリの管理は特に重要になる。 In electric vehicles such as electric vehicles (EVs), a control unit (VCU) controls the operation of components that interact with each other, such as motors, inverters, batteries, and air conditioners. . Among the components controlled by the VCU, management of the battery, which is the operating source of the electric vehicle, is particularly important.
　電動車両のバッテリ管理に係る従来技術としては、充電時間と充電後の航続可能距離との関係を明確に表示するものなどが知られている（下記特許文献１参照）。 As a conventional technology related to battery management of electric vehicles, there is a known technology that clearly displays the relationship between charging time and cruising distance after charging (see Patent Document 1 below).
特開２０１９－１０３２１２号公報JP 2019-103212 Publication
　電動移動体（例えば、電動車両）の充電基地は、充電出力が異なる（急速充電や普通充電など）ものや、充電時間に制限が設けられているものなど、充電条件が異なるものがある。充電基地に到達して電動移動体の充電を行う際に、前述した充電出力や充電時間の制限により１００％のフル充電を行うことができない場合が多い。 There are charging bases for electric vehicles (for example, electric vehicles) that have different charging conditions, such as those with different charging outputs (fast charging, normal charging, etc.), and those with restrictions on charging time. When arriving at a charging base to charge an electric mobile object, it is often impossible to fully charge the electric vehicle to 100% due to the aforementioned limitations on charging output and charging time.
　このため、電動移動体の現在位置から異なる距離に複数の充電基地が存在する場合、充電基地までの移動で消費する電力と各充電基地での充電条件の違いから、充電後のバッテリ状態が選択する充電基地によって異なる事態が生じ得る。また、充電基地の選択によって充電基地から目的地までの距離が異なる場合があるので、これらを考慮すると、電動移動体の現在位置から離れた位置に在る複数の充電基地の何れを選択するのが適当かは、難しい判断にならざるを得ない。 Therefore, when multiple charging bases exist at different distances from the current position of the electric vehicle, the battery state after charging is selected based on the power consumed in traveling to the charging base and the difference in charging conditions at each charging base. Different situations may arise depending on the charging base used. In addition, the distance from the charging base to the destination may vary depending on the selection of the charging base, so taking these into account, it is important to select which of the multiple charging bases located far from the current location of the electric vehicle. Whether this is appropriate is a difficult decision to make.
　また、現在位置から充電基地に向かうまでの間で、充電前にバッテリを冷却するなど、バッテリの温調条件を変更することができるが、バッテリの温調条件を変更した場合の効果やバッテリの温調に要する電力等を考慮すると、充電前のバッテリの温調条件をどのようにするかを含めて、現在位置から離れた位置に在る複数の充電基地の何れを選択するかを判断することが必要になる。 In addition, it is possible to change the temperature control conditions of the battery, such as cooling the battery before charging, from the current location to the charging base. Considering the power required for temperature control, etc., determine which of the multiple charging bases located far from the current location should be selected, including the temperature control conditions for the battery before charging. It becomes necessary.
　本発明は、このような事情に対処するために提案されたものである。すなわち、電動移動体の現在位置から離れた地点に存在する充電基地を選択してバッテリの充電を行うに際して、何れの充電基地を選択すべきかの判断を容易にすること、などが本発明の課題である。 The present invention was proposed to deal with such circumstances. In other words, an object of the present invention is to facilitate the determination of which charging base to select when charging a battery by selecting a charging base located at a point far from the current location of the electric mobile object. It is.
　このような課題を解決するために、本発明による電動移動体のバッテリ管理装置は、以下の構成を具備するものである。
　電動移動体における制御装置と連携してバッテリを管理する管理装置であって、現在位置から離れた地点に在る充電基地に対して、そこまで移動して充電した後のバッテリ状態を予測する管理部を備えることを特徴とする電動移動体のバッテリ管理装置。 In order to solve such problems, a battery management device for an electric vehicle according to the present invention has the following configuration.

What is claimed is: 1. A battery management device for an electric vehicle, comprising: a.
　このような特徴を備えた本発明によると、ユーザは、電動移動体の現在位置から離れた地点に存在する充電基地を選択してバッテリの充電を行うに際して、管理部の予測結果から充電後のバッテリ状態を把握することができるので、何れの充電基地を選択すべきかの判断を容易にすることができる。 According to the present invention having such features, when a user selects a charging base located at a point far from the current position of the electric mobile object to charge the battery, the user can determine the state after charging based on the prediction result of the management unit. Since the battery status can be ascertained, it is possible to easily determine which charging base to select.

　管理部１０は、空調を含むＥＶの熱マネジメントの管理を行っており、熱媒体回路部１２や空調部１３の制御を行い且つこれらの動作情報を取得している。熱媒体回路部１２は、バッテリやその他の温調対象物の温調を行う熱媒体回路（例えば、水回路）を動作させるためのポンプや流路切り替え弁や水加熱ヒータなどを含み、空調部１３は、ＥＶ室内に空調風を送風するＨＶＡＣ（Heating, Ventilation, and Air Conditioning）ユニットの構成要素である送風機やダンパや空気加熱ヒータ及び、冷媒回路の圧縮機や膨張弁などを含む。 The management unit 10 manages heat management of the EV including air conditioning, controls the heat medium circuit unit 12 and the air conditioning unit 13, and acquires operation information thereof. The heat medium circuit section 12 includes a pump, a flow path switching valve, a water heater, etc. for operating a heat medium circuit (for example, a water circuit) that controls the temperature of a battery or other temperature-controlled object, and includes an air conditioning section. Reference numeral 13 includes a blower, a damper, an air heater, a compressor of a refrigerant circuit, an expansion valve, etc., which are components of an HVAC (Heating, Ventilation, and Air Conditioning) unit that blows conditioned air into the EV room.
　管理部１０は、操作入力部４１にて入力された情報に基づいて、熱媒体回路部１２や空調部１３を制御することで、ＥＶの室内を設定温度に空調すると共に、バッテリを含む温調対象の温調制御を行う。 The management unit 10 controls the heat medium circuit unit 12 and the air conditioning unit 13 based on the information input through the operation input unit 41 to air condition the interior of the EV to a set temperature, and also to control the temperature control including the battery. Performs temperature control of the target.
　そして、管理部１０は、現在位置から離れた地点に在る充電基地まで移動して充電した後のバッテリ状態を予測し、予測したバッテリ状態を報知部４０に出力する。 Then, the management unit 10 predicts the battery state after moving to a charging base located far from the current location and charging, and outputs the predicted battery state to the notification unit 40.
　このような管理部１０は、図２に示すように、演算処理によって得られる機能として、到達可能充電基地抽出手段１０Ａ、抽出充電基地情報報知手段１０Ｂ、バッテリ温調条件選択手段１０Ｃ、充電後バッテリ状態算出手段１０Ｄ、電気料金算出手段１０Ｅなどを備えている。 As shown in FIG. 2, such a management unit 10 has functions obtained through arithmetic processing such as reachable charging base extraction means 10A, extraction charging base information notification means 10B, battery temperature control condition selection means 10C, and post-charging battery It includes a state calculation means 10D, an electricity rate calculation means 10E, and the like.
　到達可能充電基地抽出手段１０Ａは、センサ部１１から得られるＥＶの現在位置情報、ナビゲーションシステム３１から得られる目的地情報、ナビゲーションシステム３１の充電基地情報３１Ａから得られる充電基地の位置情報、バッテリ管理部３０から得られる現在のバッテリ管理情報（例えば、現在のバッテリ残量）に基づいて、現在のＥＶの位置から現在のバッテリ状態で到達可能な充電基地を抽出する。 The reachable charging base extraction means 10A extracts current position information of the EV obtained from the sensor unit 11, destination information obtained from the navigation system 31, position information of the charging base obtained from the charging base information 31A of the navigation system 31, and battery management. Based on the current battery management information (for example, current remaining battery level) obtained from the unit 30, a charging base that can be reached with the current battery state from the current EV position is extracted.
　これは、図３に示すように、センサ部１１から取得される現在位置に対してナビゲーションシステム３１等で目的地が設定されている状況において、先ず、現在のバッテリ状態で到達可能な距離Ｌｍを算出する。次に、地図情報３１Ａと充電基地情報３１Ｂによって、現在位置から目的地に至る幾つかのルート（図示の例では、ルートＬ１，ルートＬ２，ルートＬ３，ルートＬ４）の道中に存在する充電基地（図示の例では、充電基地Ａ，充電基地Ｂ，充電基地Ｃ，充電基地Ｄ）を把握する。そして、現在位置から把握された各充電基地までの道のり（移動距離）が到達可能距離Ｌｍより短い充電基地（図示の例では、充電基地Ａ，充電基地Ｂ，充電基地Ｃ）を抽出する。この際、移動中に空調部１３や熱媒体回路部１２を動作させて空調やバッテリ温調などを行う場合には、それらの動作に要する消費電力を考慮して到達可能距離Ｌｍを変化させる。 As shown in FIG. 3, in a situation where a destination is set in the navigation system 31 or the like with respect to the current position acquired from the sensor unit 11, first, the distance Lm that can be reached with the current battery state is calculated. calculate. Next, based on the map information 31A and the charging base information 31B, charging bases ( In the illustrated example, charging base A, charging base B, charging base C, and charging base D) are recognized. Then, charging bases (in the illustrated example, charging base A, charging base B, and charging base C) whose path (traveling distance) from the current position to each grasped charging base is shorter than the reachable distance Lm are extracted. At this time, when operating the air conditioner 13 and heat medium circuit section 12 to perform air conditioning, battery temperature control, etc. during movement, the reachable distance Lm is changed in consideration of the power consumption required for these operations.
　抽出充電基地情報報知手段１０Ｂは、充電基地情報３１Ｂに基づいて、到達可能充電基地抽出手段１０Ａによって抽出された充電基地（図示の例では、充電基地Ａ，充電基地Ｂ，充電基地Ｃ）の情報を報知部４０に出力する。 The extracted charging base information notification means 10B provides information on charging bases (in the illustrated example, charging base A, charging base B, and charging base C) extracted by the reachable charging base extracting means 10A based on the charging base information 31B. is output to the notification section 40.
　図４は、抽出充電基地情報報知手段１０Ｂの報知例（表示例）を示している。この例では、抽出された充電基地Ａは、「出力」が「超高速」であって超高速充電が可能な設備を備え、「制限時間」が「３０分」であり、「現在位置からの道のり」が「１２０ｋｍ」、「目的地までの道のり」が「１１０ｋｍ」であることが示され、抽出された充電基地Ｂは、「出力」が「高速」であって高速充電が可能な設備を備え、「制限時間」が「３０分」であり、「現在位置からの道のり」が「１００ｋｍ」、「目的地までの道のり」が「１００ｋｍ」であることが示され、抽出された充電基地Ｃは、「出力」が「中速」であって中速充電が可能な設備を備えており、「制限時間」が「無」（無制限）であり、「現在位置からの道のり」が「９５ｋｍ」、「目的地までの道のり」が「１２０ｋｍ」であることが示されている。ここでの「道のり」はルート上の移動距離を示している。 FIG. 4 shows a notification example (display example) of the extracted charging base information notification means 10B. In this example, the extracted charging base A has "output" of "ultra high speed" and is equipped with equipment capable of super fast charging, "time limit" is "30 minutes", and "output" is "ultra high speed", and "time limit" is "30 minutes". It is shown that the "distance" is "120 km" and the "distance to the destination" is "110 km", and the extracted charging base B has "output" of "high speed" and is equipped with equipment capable of high-speed charging. In preparation, it is shown that the "time limit" is "30 minutes", the "distance from the current location" is "100 km", and the "distance to the destination" is "100 km", and the extracted charging base C is equipped with equipment that allows medium-speed charging with "output" of "medium speed", "time limit" is "none" (unlimited), and "distance from current location" is "95 km". , it is shown that the "distance to the destination" is "120 km". "Michi" here indicates the distance traveled on the route.
　バッテリ温調条件選択手段１０Ｃは、現在値から抽出された充電基地まで移動するに間に、熱媒体回路部１２を動作させてバッテリの温調を行う際の温調条件を選択する。バッテリ温調の一例としては、夏場の外気温度が高い状況で、バッテリを冷却して充電前のバッテリ温度を所定値以下にする、充電前冷却がある。 The battery temperature control condition selection means 10C selects a temperature control condition for operating the heat medium circuit section 12 to control the temperature of the battery while moving to the charging station extracted from the current value. An example of battery temperature control is pre-charging cooling, in which the battery is cooled to bring the battery temperature before charging to a predetermined value or less in a situation where the outside air temperature is high in summer.
　充電前冷却は、バッテリ冷却の程度に応じて、単位時間当たりに充電できる電力量が変化することで、充電時間の短縮が可能になる。これに対して、充電前冷却を行うと、それによって消費電力が増えることになるので、充電コストと充電時間短縮の要否を考慮して、充電前冷却を行うか否か、或いは充電前冷却の時間等の温調条件を選択する。 Pre-charging cooling allows the charging time to be shortened by changing the amount of power that can be charged per unit time depending on the degree of battery cooling. On the other hand, if cooling before charging is performed, power consumption will increase, so it is necessary to consider whether or not to perform cooling before charging, considering the charging cost and whether or not to shorten charging time. Select temperature control conditions such as time.
　バッテリ温調条件選択手段１０は、一例として、バッテリの事前冷却を行うか否か、或いは事前充電を行う場合の程度（冷却実施時間）を設定して、これによるバッテリ充電時間の変化と充電時の電気料金を報知する。 For example, the battery temperature control condition selection means 10 sets whether or not to perform pre-cooling of the battery or the degree of pre-charging (cooling implementation time), and determines the change in battery charging time due to this and the charging time. Notify electricity rates.
　充電後バッテリ状態算出手段１０Ｄは、充電基地を選択し、充電前冷却などのバッテリ温調条件を選択した場合における充電後のバッテリ状態（バッテリ残量や充電後の航続可能距離）を予測するための演算処理を行う。この際、充電後のバッテリ状態は、選択した充電基地までの移動距離と選択した充電基地での充電条件の一方又は両方と、充電基地までの移動中に行うバッテリ温調条件とを考慮して予測される。 The post-charging battery state calculating means 10D is for predicting the battery state after charging (remaining battery level and possible cruising distance after charging) when a charging base is selected and battery temperature control conditions such as pre-charging cooling are selected. Performs calculation processing. At this time, the battery condition after charging takes into consideration the travel distance to the selected charging base, the charging conditions at the selected charging base, or both, and the battery temperature control conditions performed during the journey to the charging base. is expected.
　具体的には、充電後バッテリ状態算出手段１０Ｄは、現在のバッテリ状態と、現在位置から選択した充電基地までの移動に要する消費電力、移動中に空調を行う場合は空調に要する消費電力、移動中のバッテリ温調条件の選択に対応した消費電力、選択した充電基地での充電条件（出力と充電時間）によって充電される充電量により、充電後のバッテリ状態を算出する。この際の充電時間は、選択した充電基地での充電時間制限を考慮し、充電前冷却等のバッテリ温調条件を設定する場合には、その設定による充電時間の短縮を考慮する。 Specifically, the post-charging battery state calculating means 10D calculates the current battery state, the power consumption required for moving from the current position to the selected charging base, the power consumption required for air conditioning if air conditioning is performed during movement, and the movement. The battery state after charging is calculated based on the power consumption corresponding to the selected battery temperature control condition and the amount of charge charged according to the charging conditions (output and charging time) at the selected charging base. The charging time at this time takes into consideration the charging time limit at the selected charging base, and when setting battery temperature control conditions such as pre-charging cooling, the shortening of the charging time due to the settings is taken into consideration.
　電気料金算出手段１０Ｅは、充電基地を選択し、充電前冷却などのバッテリ温調条件を選択した場合における充電後の電気料金を予測するための演算処理を行う。この電気料金算出手段１０Ｅは、現在のバッテリ状態に対して、前述した充電後バッテリ状態算出手段１０Ｄで行った消費電力と充電量の電力収支を算出し、充電量の追加に対する電気料金を算出する。 The electricity rate calculation means 10E performs arithmetic processing to predict the electricity rate after charging when a charging base is selected and a battery temperature control condition such as pre-charging cooling is selected. This electricity bill calculation means 10E calculates the power balance of the power consumption and the amount of charge performed by the above-mentioned post-charging battery state calculation means 10D for the current battery state, and calculates the electricity bill for the addition of the amount of charge. .
　図５は、管理部１０の出力を報知部４０の表示装置に表示させる場合の表示例を示している。ここでは、地図情報３１Ａに重ねて、ＥＶの現在位置、目的地、抽出された充電基地（充電基地Ａ，Ｂ，Ｃ）の位置が表示されており、現在位置から選択対象となる複数の充電基地（充電基地Ａ，Ｂ，Ｃ）までの移動距離Ｄ１，Ｄ２，Ｄ３と、選択対象となる充電基地（充電基地Ａ，Ｂ，Ｃ）から目的地までの移動距離Ｄ４，Ｄ５，Ｄ６と、予測された充電後のバッテリ充電状態Ｄ１０とが併せて表示されている。更に、選択対象となる充電基地（充電基地Ａ，Ｂ，Ｃ）に対しては、各充電基地の充電条件（出力と充電時間制限）が示されている。 FIG. 5 shows a display example when the output of the management section 10 is displayed on the display device of the notification section 40. Here, the current position of the EV, the destination, and the positions of the extracted charging bases (charging bases A, B, C) are displayed superimposed on the map information 31A, and multiple charging stations to be selected from the current position are displayed. Travel distances D1, D2, D3 to the bases (charging bases A, B, C), travel distances D4, D5, D6 from the charging bases to be selected (charging bases A, B, C) to the destination, The predicted battery charging state D10 after charging is also displayed. Further, for the charging bases to be selected (charging bases A, B, and C), the charging conditions (output and charging time limit) of each charging base are shown.
　この際、予測された充電後のバッテリ充電状態Ｄ１０は、選択した充電基地（図示の例では充電基地Ａ）毎に求められ、バッテリ温調条件である充電前冷却実施時間が変更入力可能になっている。これによると、充電前冷却実施時間（バッテリ温調条件）を変更入力すると、その変更入力に対応して、バッテリ充電時間、充電後航続可能距離、充電時の電気料金がそれぞれ求められ表示される。 At this time, the predicted battery charging state D10 after charging is obtained for each selected charging base (charging base A in the illustrated example), and the pre-charging cooling time, which is a battery temperature control condition, can be changed and input. ing. According to this, if you change the pre-charging cooling time (battery temperature control conditions), the battery charging time, cruising range after charging, and electricity charge during charging will be calculated and displayed accordingly. .
　ユーザは、このような表示によって情報を得ることで、選択した充電基地においてそこでの充電条件に応じて充電を行った場合の充電後のバッテリ状態を把握することができる。これにより、選択した充電基地での充電後の航続可能距離を把握し、航続可能距離が選択した充電基地から目的地までの移動距離を超えているかを確認することができる。 By obtaining information from such a display, the user can grasp the state of the battery after charging when charging is performed at the selected charging base according to the charging conditions there. This makes it possible to grasp the possible cruising distance after charging at the selected charging base, and to check whether the cruising distance exceeds the travel distance from the selected charging base to the destination.
　また、選択対象の充電基地の充電条件を充電基地毎に把握することできるので、ユーザは、充電基地の選択に対して、バッテリ温調（充電前冷却）による充電時間の短縮が必要であるか否かを判断することができる。 In addition, since the charging conditions of the charging base to be selected can be grasped for each charging base, the user can determine whether it is necessary to shorten the charging time through battery temperature control (pre-charging cooling) when selecting a charging base. You can judge whether or not.
　そして、現在位置から選択した充電基地までの移動中にバッテリ温調（充電前冷却）を行う場合には、それによる電力消費で加算される電気料金が、バッテリ温調によって享受されるバッテリ充電時間の短縮効果に見合っているかを確認することができる。これらによってユーザは、移動体の現在位置から離れた地点に存在する充電基地を選択してバッテリの充電を行うに際して、何れの充電基地を選択すべきかの判断が容易になる。 If battery temperature control (pre-charging cooling) is performed during movement from the current location to the selected charging base, the additional electricity charges due to the resulting power consumption will be reduced by the battery charging time benefited by battery temperature control. You can check whether the shortening effect is worth it. These make it easy for the user to determine which charging base to select when charging the battery by selecting a charging base located at a point away from the current location of the mobile object.
