Description

本発明は、電気自動車、電動二輪車等の電動車のバッテリーの管理システムに関するもので、更に詳細には、電動車の普及を促進する為にバッテリーを交換することによりバッテリーの充電にかかる時間を解消しようとする電動車とバッテリーの管理を容易にするシステムに関するものである。   The present invention relates to a battery management system for electric vehicles such as electric vehicles and electric motorcycles, and more specifically, eliminates the time required for charging the batteries by replacing the batteries in order to promote the popularization of electric vehicles. The present invention relates to a system that facilitates management of an electric vehicle and a battery to be tried.

従来、この種の電気自動車等のバッテリーは電動車固有のものとし電動車に取り付けられており、バッテリーの充電方法は電動車に取り付けられたバッテリーを充電スタンドにおいて充電を行うか、若しくは、車庫等に設置した充電設備で充電を行っているが、充電時の充電時間は時間がかかるもので、その間は電動車の遊休時間と成り、ロス時間となるため電動車の普及のネックにもなっており、バッテリーの充電時間の解決は重要な意味を持つものである。また、バッテリーにキャパシター等を用い充電時間を短くする技術も有るが、短時間での充電には大容量の充電設備が必要とされ、充電時間の短縮による熱の急上昇や、熱によるバッテリーや周辺機器の劣化も懸念される。   Conventionally, a battery of this type of electric vehicle or the like is attached to the electric vehicle as being inherent to the electric vehicle, and the battery charging method is to charge the battery attached to the electric vehicle at a charging stand or a garage or the like The charging equipment installed in the battery is charged, but the charging time at the time of charging takes time, and during that time it becomes idle time of the electric car, and it becomes a loss time, so it becomes a bottleneck for the popularization of electric cars Therefore, the solution of the battery charging time is important. In addition, there is a technology to shorten the charging time by using a capacitor etc. for the battery, but charging with a large capacity is required for charging in a short time. There is also concern about equipment deterioration.

例えば、電気自動車、例えば軽トラック２により消耗された消耗バッテリー１Ａを回収し、その回収された消耗バッテリー１Ａを大型トラック４に搭載して同大型トラック４の走行中に充電し、その充電された充電バッテリー１Ｂを再度電気自動車に搭載して再利用するもの（特許文献１参照）や、蓄電池に入出力する電流値を積算するとともに、該蓄電池の液温、充電状態、放電電流及び自己放電電流により該積算値に補正を行うことにより該蓄電池の充放電容量を監視する装置を設けたもの（特許文献２参照）や、停電時および疑似停電時の放電特性を標準放電特性データーと比較し、蓄電池の劣化率を演算して記憶装置内に格納し、次の停電時には前記劣化率を乗じて、放電可能な時間の演算するもの（特許文献３参照）や、蓄電池の監視装置８は、蓄電池の放電電気量、充電電気量等の電池の使用状況を検出する使用状況検出手段と、使用状況検出手段の検出結果を履歴として記憶する使用状況履歴記憶手段１５とを備えており、蓄電池の使用状況の過去の履歴を知ることができるため、蓄電池を使用するユーザに蓄電池の使用の態様を検討するためのデータを提供することができ、蓄電池の交換時期や電解液の補充の時期等をユーザに知らせて、蓄電池の管理を的確に行なわせるもの（特許文献４参照）や、記憶されている充電スタンドの中から、電気自動車の現在地周辺に存在する充電スタンドを抽出し、抽出された充電スタンドの位置と、その充電スタンドに設置されている充電器の利用可能情報とを提供するもの（特許文献５参照）等が先に開示されいてる。

The display here is difficult to be clarified due to the increase in power consumption such as air conditioning due to traffic jams and excessive use of lighting, etc., but until now, more accurate values should be displayed using the current average value It is.

更に、管理センターは、
通信網等を介して管理センター、充電スタンドが接続されている。
充電スタンド情報：各充電スタンドの地図上の位置や住所、充電能力、保持バッテリー等の情報を保有する。
地図情報：走行自動車の位置関係から近隣の各充電スタンドを探したり詳しい位置情報を走行自動車に送る為に使用する。
バッテリー管理情報：電力情報保持バッテリーの固有情報を保持し、現在の使用情報を得たり、充電容量の使用料金を計算する為に使用する。 In addition, the management center
A management center and a charging stand are connected via a communication network or the like.
Charging station information: Holds information such as the location and address of each charging station on the map, charging capacity, and holding battery.
Map information: Used to find nearby charging stations based on the location of the traveling vehicle and to send detailed location information to the traveling vehicle.
Battery management information: Electricity information retention Information specific to the battery is retained and used to obtain current usage information and to calculate the charge for charging capacity.

３ 充電スタンドは、
バッテリー管理情報：現在保有のバッテリー情報（固有情報や、充電状況）を管理する。 3 The charging stand
Battery management information: Manages battery information currently held (unique information and charging status).

管理センターのスタンド検索は、
検索要求受信：走行自動車からの現在位置や、使用バッテリーの固有情報、充電残容量を受信する。
バッテリー情報検索：当該管理センターの扱っているバッテリーである事をチェックする。（リースや貸出契約等）
交換可能スタンド検索：走行自動車の現在位置とバッテリー残量を基に、該当型のバッテリー交換即時可能な最寄りの充電スタンドを検索する。
検索結果から該当先がなければ、充電可能な充電スタンドを検索する。
検索情報送信：これからの検索結果を走行自動車に送信する。 Search for stands in the Administration Center
Retrieval request reception: Receives the current position from the traveling vehicle, the specific information of the battery used, and the remaining charge capacity
Battery information search: Check that the battery is handled by the management center. (Lease and loan contracts, etc.)
Interchangeable stand search: Based on the current position of the traveling vehicle and the remaining battery level, the nearest charging station where the corresponding battery can be replaced is searched.
If there is no corresponding destination from the search result, a chargeable charging station is searched.
Search information transmission: The search result is transmitted to the traveling vehicle.

料金計算は、
計算要求受信：充電スタンドは走行自動車から取り外した（交換した）バッテリー固有情報や電力保有容量を基に管理センターに計算要求を行う。
バッテリー情報検索：該当バッテリーの検索を行い管理対象バッテリーで有る確認をする。
バッテリー使用計算：登録時の当初電力保有量から交換時残存電力保有容量の差を求め消費電力の料金を求める。また、この際充電量が増える事もあり得る。充電量が多いバッテリーは一般に交換の必要性は発生しない。充電量が増えた際は充電料金が戻ることになる。充電スタンドに充電したバッテリーの充電料金を販売する事になる充電スタンドで充電処理が賄えない時等に有効な手段となる。また、充電スタンド間のバッテリー交換にも利用できる。一般には、バッテリーのリースや貸出料金によるトータル金額で必ずしも戻るとは限らない。
使用料金の送信：消費電力の料金を充電スタンドに送信する。
使用料金の支払いは管理センターが管理したり、充電スタンドがその場で受け取る方法もある。あくまでも契約の形態によるもので良い。
また、この料金システムは電動車自身から問い合わせて現在の料金を確認する等に使用しても良いものである。
また、現在の状況で充電スタンドでバッテリー交換を行つた場合の金額の確認としても使用できる。
バッテリーは自然放電をする特性がある。電動車をしばらく放置すると、バッテリーの残存電力保持容量が現象する。自然放電による消費電力も料金の対象になるのは当然である。また、一般家庭等で充電を行い電力保持容量を増加する事も可能である。消費電力の料金はバッテリー交換を行った際の電力保持容量の増減とする。
また、バッテリーの使用頻度にバッテリーの充放電量や回数を加えても良く、これらの使用頻度を料金、管理費に加算する方式を用いても良いものである。 Charge calculation is
Calculation request reception: The charging station makes a calculation request to the management center based on the battery-specific information removed from (replaced by) the traveling vehicle and the power holding capacity.
Battery information search: Search for the corresponding battery and confirm that it is a managed battery.
Battery usage calculation: The difference in the remaining power holding capacity at the time of replacement is obtained from the initial power holding amount at the time of registration, and the charge for power consumption is obtained. In this case, the charge amount may increase. A battery with a large charge generally does not need to be replaced. When the amount of charge increases, the charge will return. This is an effective means when the charging station that sells the charging fee of the battery charged in the charging station cannot fulfill the charging process. It can also be used for battery replacement between charging stations. In general, the total amount due to battery leasing and rental fees does not always return.
Transmission of usage fee: Transmits the power consumption fee to the charging station.
Payment of the usage fee can be managed by the management center or received at the charging station on the spot. It may be in the form of a contract to the last.
In addition, this fee system may be used to check the current fee by inquiring from the electric vehicle itself.
It can also be used to confirm the amount of money when the battery is replaced at the charging stand in the current situation.
The battery has a characteristic of spontaneous discharge. If the electric vehicle is left for a while, the battery's remaining power holding capacity will occur. Naturally, power consumption due to natural discharge is also subject to charges. It is also possible to increase the power holding capacity by charging in a general home. The charge for power consumption is the increase or decrease of the power holding capacity when the battery is replaced.
In addition, the charge / discharge amount and number of times of the battery may be added to the usage frequency of the battery, and a method of adding the usage frequency to the charge and management cost may be used.
