Description

本発明は、充電式自動車の走行に必要な充電式電池の共同利用とその管理に関する。   The present invention relates to shared use and management of a rechargeable battery necessary for running a rechargeable automobile.

地球温暖化対策の一環として、電気自動車が注目されている。電気自動車とは、電動機を動力発生源として推進する自動車をいうが、走行中に外部からエネルギーの供給を受けず、電力を供給する装置が、車内に搭載されている電気自動車と搭載されていないものに分けられる。前者には、内燃機関とモーターを並列的に用いるハイブリッドカーも含まれるが、ここでは、走行中は、外部からエネルギーの供給を受けることなく、搭載された充電式電池(以下略して電池とする。)のみにより電動機を動かし、その電池を車外の設備を用いて充電するものを充電式自動車というものとする。また充電式自動車には二輪車も含まれるものとする。(以下同じ。) Electric cars are attracting attention as part of global warming countermeasures. An electric vehicle refers to a vehicle that uses an electric motor as a power generation source, but does not receive energy from the outside during travel, and a device that supplies power is not mounted with an electric vehicle mounted in the vehicle. Divided into things. The former includes a hybrid car that uses an internal combustion engine and a motor in parallel. Here, while driving, the rechargeable battery (hereinafter abbreviated as a battery) is mounted without receiving energy supply from the outside. )) To move the electric motor and charge the battery using equipment outside the vehicle is called a rechargeable vehicle. Also, rechargeable vehicles include motorcycles. (same as below.)

充電式自動車は、内燃機関自動車よりエネルギーの利用効率が高く、二酸化炭素の排出量もはるかに少ないとされる。しかし、ガソリンと標準的なリチウム電池では、単位質量当たりのエネルギー密度には、約100倍もの差があり、内燃機関自動車の熱効率を約20%、充電式自動車の熱効率を約80%と推定しても、ガソリンと同量の電池を充電式自動車が搭載した場合には、ガソリン車の約1/25の距離しか走行できず、実用化するには、電池を多く搭載する必要がある。充電式自動車でガソリン車と同じ走行距離にしようとすると、電池を大型にする必要があり、数百Kgの重量増しとなってしまう。そこで、電池重量を制限することが余儀なくされ、必然的に走行距離は短くなり、充電を頻繁に行う必要が生ずる。 Rechargeable vehicles are said to have higher energy use efficiency and much less carbon dioxide emissions than internal combustion engine vehicles. However, there is a difference of about 100 times in energy density per unit mass between gasoline and standard lithium batteries, and the thermal efficiency of internal combustion engine vehicles is estimated to be about 20%, and that of rechargeable vehicles is estimated to be about 80%. However, when a rechargeable vehicle is equipped with a battery of the same amount as gasoline, it can travel only about 1/25 of the distance of a gasoline vehicle, and it is necessary to install many batteries for practical use. If it is going to be the same mileage as a gasoline car with a rechargeable car, it will be necessary to enlarge a battery, and it will increase the weight of several hundred kilograms. Therefore, it is necessary to limit the battery weight, which inevitably shortens the travel distance and requires frequent charging.

このように、充電式自動車を普及させるためには、街路や高速道路での急速充電できる設備が必要である。また、電池への充電時間は、急速充電器を使用しても数十分かかり、ガソリン給油時間は約5分であり、その分、ガソリン給油設備の数倍もの急速充電設備の設置が必要となってくる。急速充電であっても、充電時間は数十分かかり、この間じっと待っていることは難しく、充電式自動車メーカーでは、買い物時間中に充電するため、大型ショッピングセンタと協力して、その駐車場に充電設備を設ける計画や、急充電式自動車メーカーの中には、電池を充電するのではなく、電池を交換する方式も考えられている。 Thus, in order to popularize rechargeable vehicles, facilities capable of rapid charging on streets and highways are necessary. In addition, the battery charging time takes several tens of minutes even if a quick charger is used, and the gasoline refueling time is about 5 minutes, and it is necessary to install a quick charging facility several times that of the gasoline refueling facility. It becomes. Even with fast charging, it takes several tens of minutes to charge, and it is difficult to wait for a while. Rechargeable car manufacturers work with large shopping centers in order to charge during shopping hours. Some plans for installing charging facilities and quick rechargeable automakers have considered replacing the battery instead of charging it.

充電式自動車の使用者が、電池を充電するのではなく、電気容量が少なくなった電池を交換し、充電された電池に積み替えて、電気容量が少なくなった電池は、まとめて充電し、交換のための準備しておくシステムを作る方が、充電器の設備投資や待ち時間を考慮すると便利である。そこで、充電式自動車の利用者を対象として、共同して電池を使用する電池共有管理システムを提供するものである。 The user of the rechargeable car does not charge the battery, but replaces the battery with reduced electric capacity, reloads it with the charged battery, and charges and replaces the battery with reduced electric capacity at once. It is more convenient to make a system that prepares for the battery, considering the equipment investment and waiting time of the charger. Therefore, a battery sharing management system for jointly using batteries is provided for users of rechargeable vehicles.

充電式自動車の電池の充電あるいは交換に関する先行技術は、多くあり、中でも関連する先行技術としては、バッテリの互換・循環利用システムの契約(特許文献1、2)、バッテリの電力保有量等と交換・充電管理方法(特許文献3)、二次電池充放電循環型保守管理システム(特許文献4)等がある。 There are many prior arts related to charging or exchanging batteries of rechargeable vehicles. Among them, related prior arts include battery compatibility / circulation usage system contracts (Patent Documents 1 and 2), battery power holding amount, etc. A charge management method (Patent Document 3), a secondary battery charge / discharge circulation maintenance management system (Patent Document 4), and the like.

上記特許文献1,2では、電池の互換・循環利用の考え方は記載されているが、その方法はやや具体性に欠けている。特許文献3では、充電式自動車等に使用する電池を共有するとする思想はなく、特許文献4では、二次電池に使用する電解液の補充に関するものである。 In Patent Documents 1 and 2 described above, the idea of battery compatibility / circulation is described, but the method is somewhat lacking in specificity. In Patent Document 3, there is no idea to share a battery used for a rechargeable automobile or the like, and Patent Document 4 relates to replenishment of an electrolytic solution used for a secondary battery.

本発明の解決しようとする課題は、充電式自動車の所有者が使用する電池を共有化し、充電し管理する団体を創り、この団体が充電された電池を供給する等充電待ち時間を排除し、電池の有効利用を図り、充電式自動車の普及をめざすものである。 The problem to be solved by the present invention is to share a battery used by the owner of a rechargeable vehicle, create an organization that charges and manages, eliminates charging waiting time such as supplying a charged battery by this organization, It aims at the effective use of batteries and the spread of rechargeable vehicles.

電池共有管理団体(以下本団体とする。)は、権利能力を有していれば足り、法人格であるか否かは問わない。本団体は、充電式自動車メーカーや電力会社が発起人となることも考えられる。充電式自動車には、四輪車だけでなく二輪車も含まれる。電池共有管理団体は、当初数か所の電池ステーションを設け、交換用の電池である会員共有電池を一定量準備して、電池ステーションに保管する。電池は、前述のように特に断りがない限り充電式電池をいうものとする。電池は、四輪車と二輪車では異なる場合もあるが、形状や充放電機構はできるだけ同じものが好ましい。電池ステーションのすべてに電池の充電器を設置する必要はなく、交換された電池を充電器のある電池ステーションに集め、充電等して充電器のない電池ステーションに戻し保管することもできる。 The battery sharing management organization (hereinafter referred to as “the organization”) need only have rights and capabilities, and it does not matter whether it is a legal person or not. The organization may be founded by rechargeable car manufacturers or power companies. Rechargeable vehicles include not only four-wheeled vehicles but also two-wheeled vehicles. The battery sharing management group initially establishes several battery stations, prepares a certain amount of member shared batteries, which are replacement batteries, and stores them in the battery stations. As described above, the battery is a rechargeable battery unless otherwise specified. The battery may differ between a four-wheeled vehicle and a two-wheeled vehicle, but the same shape and charging / discharging mechanism are preferable as much as possible. It is not necessary to install battery chargers in all the battery stations, and the replaced batteries can be collected in a battery station with a charger, charged, and returned to a battery station without a charger for storage.

充電式自動車の所有者は、本団体の会員になるときに、名前、住所、車種等を記載し、それが本団体のホストコンピュータ(以下ホストコンピュータの略す。)に記録され、暗証番号等が付された会員カードが渡される。この会員カードは、ICカードであることが望ましい。 When the owner of a rechargeable car becomes a member of the organization, the name, address, vehicle type, etc. are entered and recorded on the organization's host computer (hereinafter abbreviated as host computer), and the PIN number, etc. is recorded. The attached membership card is handed over. This membership card is preferably an IC card.

この会員カードにより、本団体が運営する電池ステーションにおいて、会員は、会員カードを提示し、電池交換のサービスが受けることができる。電池交換時には、会員の電池の交換回数、電池ステーションの場所、日時や曜日等の会員情報が電池ステーションに記録される。会員情報とは、会員の氏名・住所等だけでなく、電池を交換した回数、場所、日時等も含まれる。さらに、電池充電のときに、電池の使用時間、放電容量、残存容量、充電容量、充電回数及びその所要時間や電池の状態等が測定され記録される。これらの測定は、電池の使用量と劣化状態を知るためであり、上記測定項目は、例示に過ぎず、すべての測定を行う必要はなく、電池の使用量と劣化状態を知ることができれば足りる。この電池の使用量と劣化状態を知るための電池の変化や測定値を電池情報とする。電池の状態とは、電池内のイオン濃度の変化等化学的・物理的変化や数値をいい、電池の使用量と劣化状態を知るための情報となるものである。電池には、寿命があり、使用できなくなった電池は更新して会員の走行中に支障をきたさないためである。この会員情報と電池情報は、ホストコンピュータに連絡され、会員の使用量、電池の管理の記録とされる。それらの記録から会員共有電池数量や劣化状態を管理し、所定期間での会員の電池使用量を算出する。また会員の充電式自動車購入時に付いていた電池が、本団体が使用する電池と同じ仕様ならば、その電池は会員共有電池とする。この場合、本団体がこの電池を購入することも一方異なる仕様の電池であれば、電池交換や充電ができないため、会員共有電池と入れ替える。そして、会員の所有する充電式自動車の電池は、すべて会員共有電池とする。なお、連絡とは、無線、インターネットを含む有線等を使用して情報を伝達することをいう。(以下同じ。) With this membership card, the member can present the membership card and receive a battery exchange service at the battery station operated by this organization. When the battery is replaced, member information such as the number of battery replacements of the member, the location of the battery station, the date and time, and the day of the week is recorded in the battery station. The member information includes not only the name and address of the member, but also the number of times the battery has been replaced, the location, the date and time, and the like. Further, when the battery is charged, the battery usage time, discharge capacity, remaining capacity, charge capacity, number of times of charge, required time, battery state, and the like are measured and recorded. These measurements are for knowing the usage and deterioration state of the battery. The above measurement items are merely examples, and it is not necessary to perform all measurements. It is sufficient if the usage and deterioration state of the battery can be known. . Battery changes and measured values for knowing the battery usage and deterioration state are used as battery information. The state of the battery refers to a chemical / physical change such as a change in the ion concentration in the battery or a numerical value, and is information for knowing the usage amount and the deterioration state of the battery. This is because the battery has a lifetime, and the battery that can no longer be used is renewed so as not to hinder the member's running. This member information and battery information are communicated to the host computer and recorded as a member usage amount and battery management record. The member shared battery quantity and deterioration state are managed from these records, and the battery usage of the member in a predetermined period is calculated. If the battery attached to the member's rechargeable car is the same as the battery used by the organization, the battery shall be a member-shared battery. In this case, if this organization purchases this battery, it is not possible to replace or charge the battery if the battery has a different specification. And all the batteries of the rechargeable car which a member owns shall be a member shared battery. Note that the term “contact” refers to transmitting information using wireless communication or wired communication including the Internet. (same as below.)

ホストコンピュータにより算出された会員の電池使用料金は、所定期間毎に本団体から会員に請求される。 The member's battery usage fee calculated by the host computer is charged to the member by the organization every predetermined period.

続いて、請求項2の発明は、電池共有管理団体が、会員情報と、電池情報をもとに、ホストコンピュータが、本団体が所有する電池数量を算出し、さらに、電池ステーション毎の1日当たりの電池交換回数、交換する曜日、時間別の集計をし、その集計を基に、各電池ステーションに準備する電池を算出し、保管する請求項1の会員共有電池の管理方法である。 Subsequently, according to the invention of claim 2, the battery sharing management organization calculates the number of batteries owned by the organization based on the member information and the battery information, and further, per day for each battery station. The member shared battery management method according to claim 1, wherein the number of battery exchanges, the day of the week for replacement, and the time are totaled, and the battery prepared for each battery station is calculated and stored based on the total.

電池共有管理団体が準備する電池量は、必ずしも会員の人数分準備する必要はない。会員は、その所有する充電式自動車には、必ず電池が収納されており、それぞれの会員が毎日充電式自動車を使用するとは限らないためである。そこで、各電池ステーションから来る会員情報と電池情報をホストコンピュータに取り込み、ホストコンピュータに内蔵された集計方法により本団体が準備する電池量が算出される。内蔵された集計方法とは、品切れの確立や在庫量と損益の関係から組み立てられている適正在庫量を算出するプログラムが該当し、電池の適正保管数量は、会員が増えていけば、それに比例して正確度は向上する学習機能を有し、電池の適正保管数量は、より正確な数値に更新されていく。 The battery amount prepared by the battery sharing management organization does not necessarily have to be prepared for the number of members. This is because a member always has a battery stored in a rechargeable vehicle owned by the member, and each member does not always use a rechargeable vehicle every day. Therefore, the member information and the battery information coming from each battery station are taken into the host computer, and the battery amount prepared by this organization is calculated by the counting method built in the host computer. The built-in counting method is a program that calculates the appropriate stock quantity that is assembled from the establishment of out-of-stock and the relationship between inventory quantity and profit / loss, and the appropriate storage quantity of batteries is proportional to the increase in the number of members. Thus, a learning function for improving accuracy is provided, and the appropriate storage quantity of the battery is updated to a more accurate value.

電池は、自然放電するため、満充電してもその後長時間使用せず保管すれば、充電容量は減少していく。そこで電池の交換のときに満充電にしておくことが望ましい。しかし、会員がいつ電池を交換しに来るかを予測することは難しい。そこで、ホストコンピュータに内蔵された集計方法により、電池ステーションでの1日当たりの電池交換回数、交換する曜日、時間別の集計をとり、その集計を基に電池を充電する時期と数量が決まり、各電池ステーションに満充電された電池が保管され、会員の電池交換の需要に応えるようにする。ホストコンピュータにより算出された電池の各電池ステーションでの準備数量は、電池ステーションに連絡され、充満電した電池が曜日や時間ごとに適正数量準備される。この集計方法も、電池交換の場所、曜日、時間帯等のデータより、交換の散布図を作成し、その散布図から、関係式を求める機能等を有するプログラムがホストコンピュータに内蔵され、各電池ステーションで、電池を充電する時期と数量が算出される。かかる算定も学習機能を有し、会員数が多くなり、電池の交換回数が増すとともに正確度が上昇するようになる。 Since the battery spontaneously discharges, if it is stored for a long time after being fully charged, the charging capacity decreases. Therefore, it is desirable to fully charge the battery when replacing it. However, it is difficult to predict when a member will come to change batteries. Therefore, the counting method built in the host computer takes the total number of battery replacements per day at the battery station, the day of the week for replacement, and the time-based total, and the time and quantity for charging the battery are determined based on the total. A fully charged battery is stored in the battery station to meet the member's demand for battery replacement. The prepared quantity of the battery at each battery station calculated by the host computer is communicated to the battery station, and an appropriate quantity of fully charged batteries is prepared for each day of the week or time. This calculation method also creates a scatter diagram of replacement from data such as battery replacement location, day of the week, and time zone, and a program having a function for obtaining a relational expression from the scatter diagram is built in the host computer. At the station, the time and quantity for charging the battery are calculated. Such calculation also has a learning function, the number of members increases, and the accuracy increases as the number of battery replacements increases.

続いて、請求項3の発明は、電池にはICチップを埋め込み、電池の充電器には、読み取り装置及び情報伝達装置を取り付け、交換された電池を充電するとき、電池のICチップから電池情報がホストコンピュータに連絡され、記録される請求項1の会員共有電池の管理方法である。 Subsequently, the invention of claim 3 embeds an IC chip in the battery, a reading device and an information transmission device are attached to the battery charger, and the battery information is obtained from the IC chip of the battery when the replaced battery is charged. The member shared battery management method according to claim 1, wherein is stored in contact with a host computer.

電池に埋め込まれたICチップには、温度、イオン濃度、電圧・電流を感知するセンサー等が具備した回路が形成され、放電容量や電池の状態等の電池情報がICチップに記憶される。また電池の充電器には、読み取り装置及び情報伝達装置を取り付け、電池の充電時に、ICチップの情報を読み取りホストコンピュータに直接その情報を連絡できるようにしておく。充電時の充電量や充電時間もホストコンピュータに連絡される。この方法により、正確・迅速に電池情報がホストコンピュータに記録され、電池の使用量や劣化状態が管理される。 The IC chip embedded in the battery is provided with a circuit including sensors for detecting temperature, ion concentration, voltage / current, etc., and battery information such as discharge capacity and battery state is stored in the IC chip. In addition, a reading device and an information transmission device are attached to the battery charger so that when the battery is charged, the information on the IC chip is read and the information can be directly communicated to the host computer. The host computer is also notified of the amount of charge and the charging time during charging. By this method, battery information is recorded accurately and quickly in the host computer, and the amount of use and the deterioration state of the battery are managed.

続いて、請求項4の発明は、会員カードをICカードとし、電池ステーションにて会員カードの読み取り情報伝達機能を設け、提示さされた会員カードの情報をホストコンピュータに連絡するとともに、ホストコンピュータに記録された個人情報をその会員カードに記録する請求項1の会員共有電池の管理方法である。 Subsequently, the invention of claim 4 uses the membership card as an IC card, provides a membership card reading information transmission function at the battery station, and informs the host computer of the presented membership card information. 2. The member shared battery management method according to claim 1, wherein the recorded personal information is recorded on the member card.

会員カードをICカードとすることにより、ホストコンピュータに直接会員情報が連絡され記録される。またホストコンピュータから会員カードにホストコンピュータ内に記録された会員の電池交換回数や使用料が連絡され、相互の連絡が迅速に行うことができ、会員は支払う使用料等をその場で知ることができる。 By using a membership card as an IC card, membership information is directly communicated to the host computer and recorded. In addition, the member's battery exchange number and usage fee recorded in the host computer are notified from the host computer to the membership card, so that mutual communication can be made quickly, and the member can know the usage fee to be paid on the spot. it can.

つづいて、請求項5の発明は、各電池共有管理団体の会員が、他の電池共有管理団体の電池ステーションにても電池の交換ができる請求項1の会員共有電池の管理方法である。 Next, the invention of claim 5 is the member shared battery management method according to claim 1, wherein a member of each battery sharing management group can exchange batteries even at a battery station of another battery sharing management group.

全国的な電池共有管理団体を創るのは、困難であり、各地域に資本等が異なる電池共有管理団体が存在することになると予想される。充電式自動車は、ガソリン車に比べ満充電にしたときでもその走行距離は短く、約200Km以下といわれている。この走行距離では旅行等遠距離の移動をすることはできない。電池共有管理団体が異なる会員であっても、他の電池共有管理団体の電池ステーションにて電池を交換できれば、遠距離移動する会員にとっては便利である。そこで電池共有管理団体のホストコンピュータを互いに連絡させ、会員情報、電池情報の交換を行い、電池共有管理団体の電池ステーションにおいて他の団体の会員が電池の交換サービスを受けるようにする。 Creating a nationwide battery sharing management organization is difficult, and it is expected that there will be battery sharing management organizations with different capitals in each region. A rechargeable car is said to have a shorter mileage even when fully charged compared to a gasoline car, approximately 200 km or less. It is not possible to move at a long distance such as travel at this distance. Even if the battery sharing management group is a different member, it is convenient for a member who travels a long distance if the battery can be exchanged at the battery station of another battery sharing management group. Therefore, the host computers of the battery sharing management organization are contacted to exchange member information and battery information so that members of other organizations can receive a battery replacement service at the battery station of the battery sharing management organization.

請求項1の発明では、電池共有管理団体が会員共有電池を準備し、本会員は、放電した電池を充電することなく、満充電した電池に交換することができるため、充電するまで待つ必要はなく、会員共有電池であるため、電池の有効利用が可能であり、充電式自動車の普及に効果がある。
請求項2の発明では、会員情報と電池情報をもとに、電池の適正保管数量が算出され、さらに電池への充電時期と電池ステーションへの電池の配置を適正にすることができ、会員の電池使用料の低減を図ることができる。
請求項3の発明では、電池に埋め込まれたICチップに電池情報が記録されるため、充電時に電池情報を測定する必要はなく、充電器の読み取り装置及び情報伝達装置により、その電池情報が迅速にホストコンピュータに伝達できる。
請求項4の発明では、会員カードをICカードにすることにより、ホストコンピュータだけでなく会員も会員情報の内容を知ることが可能となる。
請求項5の発明では、他の電池共有管理団体の会員であっても電池ステーションにて電池の交換をすることができ、遠距離移動する会員には便利である。
In the invention of claim 1, the battery sharing management organization prepares the member shared battery, and the main member can replace the discharged battery with a fully charged battery without charging, so there is no need to wait until charging In addition, since the battery is a member-shared battery, the battery can be used effectively, which is effective for the spread of rechargeable vehicles.

図3はICチップが埋め込まれた電池1での電池情報の流れである。電池には、温度、電圧、電流、イオン濃度の各センサーがICチップにつながれた回路が組まれている。ICチップには、電池使用中の温度等の各数値が記録される。電池を充電するとき、充電器2に内の読み取り装置によりICチップの数値が読み取られる。さらに充電時の充電容量、充電時間も記録される。ICチップの情報と充電時の情報が電池情報となって充電器内の情報伝達伝装置を介してデータ送受信部3を通りホストコンピュータ4に記録される。この電池情報により電池の使用量や劣化状態を算出し、電池の適正保管数や使用料金が決められる。 FIG. 3 is a flow of battery information in the battery 1 in which the IC chip is embedded. The battery has a circuit in which sensors for temperature, voltage, current, and ion concentration are connected to an IC chip. Each numerical value such as temperature during battery use is recorded on the IC chip. When charging the battery, the value of the IC chip is read by the charger 2 in the charger 2. In addition, the charging capacity and charging time during charging are also recorded. The information on the IC chip and the information at the time of charging become battery information and are recorded in the host computer 4 through the data transmission / reception unit 3 via the information transmission device in the charger. Based on this battery information, the amount of battery used and the state of deterioration are calculated, and the appropriate number of stored batteries and usage fee are determined.

図4は、電池の劣化状態の指標例である。電池のICチップ及び充電時の充電容量や時間等の電池情報がホストコンピュータに記録される。この記録から図4のような指標を集計プログラムより算出し、一定基準を満たさなくなった電池を廃棄処分にする。 FIG. 4 is an example of an indicator of the deterioration state of the battery. Battery information such as the battery IC chip and the charging capacity and time during charging is recorded in the host computer. Based on this record, an index as shown in FIG. 4 is calculated from the aggregation program, and a battery that no longer satisfies a certain standard is disposed of.

充電式自動車の製造販売が迫ってきている。この電池の充電は家庭の電源を使用できるがその充電時間は10時間以上である。また急速充電器を使用した場合には数十分で充電できるといわれているが、各家庭に急速充電器を設置することは困難であり、充電式自動車の普及を妨げる要因となっている。そこで、電池を共有化し、放電した電池は、満充電した電池に交換する方法を採用すれば、充電の待ち時間の解消となり、電池の適正保管数量が維持でき充電式自動車の利用範囲が広がるものと考えられる。従って電池共有管理団体と会員共有電池の考え方は、今後の指針となると思われる。 Manufacture and sales of rechargeable vehicles are imminent. The battery can be charged using a household power supply, but the charging time is 10 hours or more. Although it is said that a quick charger can be used for charging in several tens of minutes, it is difficult to install a quick charger in each home, which is a factor that hinders the spread of rechargeable vehicles. Therefore, if the battery is shared and the discharged battery is replaced with a fully charged battery, the charging waiting time is eliminated, the appropriate storage quantity of the battery can be maintained, and the range of use of the rechargeable vehicle is expanded. it is conceivable that. Therefore, the idea of the battery sharing management organization and the member shared battery will be a guideline for the future.
