PROBLEM TO BE SOLVED: To provide a charger which shortens a length of the charging time that is a weak point of a current electric vehicle.SOLUTION: Electricity is transferred from power supply ports 1, 2, 3 connected with power supply cables 12, 13, 14. Then, switches 4, 5, 6 are turned on and switches 7, 8 are turned off, and current is flowed to each cell 9, 10, 11 and the cells are charged. When a vehicle is driven, the switches 4, 5, 6 are turned off and the switches 7, 8 are turned on to conduct electricity.

Description

本発明は電気自動車、電気トラック等における充電方法に関するものである。  The present invention relates to a charging method for an electric vehicle, an electric truck or the like.

今までの充電方法によれば、速く充電するためには急速充電器を使うしかなかった。しかし、これでは電池の劣化を招き、蓄電池の寿命が短くなる。よって長距離運転するトラックや旅行者は数回使っただけでバッテリーが傷み、自動車を買い直さなければならなくなる。  According to the conventional charging method, the only way to charge quickly is to use a quick charger. However, this causes battery deterioration and shortens the life of the storage battery. Therefore, trucks and travelers who drive long distances can damage the battery after just using it a few times and have to buy a new car.

電気自動車を昼使う場合、夜、普通充電で充電すれば良いと言っているが、忘れた場合困る。特に高齢者等の方にはその対策が必要である。  When using an electric car in the daytime, it is said that it should be charged at normal charge at night. Especially for elderly people, the countermeasures are necessary.

バッテリーが傷んだ場合、新しい電池と交換すれば良いという声もあるが、それでは電気自動車ではなく電池自動車である。  Some say that if the battery is damaged, you can replace it with a new one, but it's a battery car, not an electric car.

本願発明においては次の非特許文献を踏まえて述べていく。  The present invention will be described based on the following non-patent documents.

御堀直嗣著「図解入門よくわかる最新、電気自動車の基本と仕組み」株式会社、秀和システム ２０１１年２月２５日発行  Published by Naomi Obori, “Latest, Basics and Mechanisms of Electric Vehicles that can be Learned in an Introductory Way”, Hidekazu System, February 25, 2011

上述の如く、現状における電気自動車は問題が多い。一回の充電に八時間もかかるというのでは、いささか長いと思わずにはいられない。  As described above, current electric vehicles have many problems. If it takes 8 hours to charge a battery, it can't be helped because it's a little long.

夜間電力で充電すれば良いというが、万一忘れた時は近くに電気スタンドがないと仕事にいけなくなる。  Charging at night power is sufficient, but if you forget it, you can't work without a desk lamp nearby.

本発明はこのような点を顧みて成されたものであり、その目的は充電時間の短縮を図るということである。  The present invention has been made in view of these points, and its purpose is to shorten the charging time.

まず電気自動車のバッテリーを各セルごとに分割する。そして各セルごとに充電するのである。  First, the electric vehicle battery is divided into cells. And it charges for every cell.

電気自動車のバッテリーを各セルごとに分割し、その一セル、一セルごとに充電する。そうすることによってｎ個のセルに分割されたバッテリーの場合、満電になるまでの時間が１／ｎに短縮される。  The battery of the electric vehicle is divided for each cell, and the cell is charged for each cell. By doing so, in the case of a battery divided into n cells, the time until full charge is shortened to 1 / n.

以下、本発明を図面に基づき説明する。  Hereinafter, the present invention will be described with reference to the drawings.

まず、充電の仕方について述べる。  First, how to charge is described.

給電口１、２、３から給電された電気はスイッチ４、５、６をＯＮにし、スイッチ７、８をＯＦＦにすることによって各セル９、１０、１１に届けられる。そうして各セルが満電、あるいは、ある一定の量になるまで充電される。  The electricity supplied from the power supply ports 1, 2, 3 is delivered to the cells 9, 10, 11 by turning on the switches 4, 5, 6 and turning off the switches 7, 8. Then, each cell is charged until it is fully charged or reaches a certain amount.

つまり、本発明では給電口が２個以上あるのであり、そこへつなぐケーブルの数も給電口の数、ｎ個と同じ数、つまりｎ本でなければならない。  That is, in the present invention, there are two or more power supply ports, and the number of cables connected to the power supply ports must be the same as the number of power supply ports, n, that is, n.

したがって電気スタンド、または家ではｎ本の電気ケーブルを用意しておかなければならない。  Therefore, n electric cables must be prepared at the desk lamp or at home.

もちろん、このケーブルは急速充電のものではなく、普通充電のケーブルである。よってバッテリーの劣化がない。  Of course, this cable is not for quick charging, but for normal charging. Therefore, there is no deterioration of the battery.

具体的に考えてみると８時間で満電になる電気自動車であれば、２本で４時間、４本で２時間、３２本で１５分で満電になる。  Specifically, if an electric car is fully charged in 8 hours, it will take 4 hours for 2 cars, 2 hours for 4 cars, and 15 minutes for 32 cars.

次に運転時、つまり放電する場合だが、スイッチ４、５、６をＯＦＦにし、スイッチ７、８をＯＮにする。そうすることによってセル９、１０、１１がつながり、上手く放電ができ、電気がモーターに伝わって車輪が回り、車が動く。  Next, during operation, that is, when discharging, switches 4, 5, and 6 are turned off, and switches 7 and 8 are turned on. By doing so, the cells 9, 10, 11 are connected, and the discharge can be performed well. Electricity is transmitted to the motor, the wheels rotate, and the car moves.

給電口は図２のようにボンネットにしてあるが、これは各自、自由である。とにかくバッテリーにつながれば良いのである。  The power supply port is a bonnet as shown in FIG. 2, but this is free to each person. Anyway, just connect it to the battery.

肝心のスイッチのＯＮ、ＯＦＦの仕方だがコンピューターにやってもらうか、手動でもかまわない。  The important way to turn the switch on and off is to get it done by a computer or manually.

以上、この発明の主要な部分を説明したが、ある程度の自由はある。つまり、電気ケーブルの数は自由にしておけば良く、充電時間が３０分でも構わないとすれば、電気ケーブルの数は１６本にしてもよい。  As mentioned above, although the main part of this invention was demonstrated, there is a certain amount of freedom. In other words, the number of electrical cables may be set freely, and the number of electrical cables may be 16 as long as the charging time may be 30 minutes.

Claims (2)

給電口を多くした電気自動車であって、給電口に給電ケーブルを各々つなぎ、各スイッチをＯＮ、ＯＦＦすることによってバッテリーの各セルに直接、通電することにより、充電する装置  An electric vehicle having a large number of power supply ports, each of which is connected with a power supply cable to the power supply port, and is charged by directly energizing each cell of the battery by turning on and off each switch. 給電口を多くしたことに特徴があって、これで普通充電による急速充電が可能になり、従来の急速充電によるバッテリーの劣化を防ぐ。  It is characterized by an increase in the number of power supply ports. This makes it possible to perform quick charging by normal charging, and prevents deterioration of the battery by conventional quick charging.
