本発明は、バッテリ（蓄電池）を主動力源として走行する電気自動車のバッテリ交換方法および電気自動車のバッテリ搭載構造、並びに電気自動車に関するものである。 [0001]
Field of the Invention
The present invention is a battery (storage battery) the battery mounting structure of the battery exchange process, and an electric vehicle of an electric vehicle running as the main power source, and to an electric vehicle.

本発明は、バッテリの搬入・搬出作業を一連の作業で行うことができる電気自動車のバッテリ交換方法および電気自動車のバッテリ搭載構造、並びに電気自動車を提供することをその目的としている。 The present invention is directed to a battery mounting structure for a battery replacement method and an electric vehicle of an electric vehicle the loading and unloading operations can be carried out in a series of operations of the battery, as well as to provide an electric vehicle and an object.

同様に、バッテリユニットを構成する複数のバッテリは、各バッテリの各極端子が交互に係脱する一対の導通部材を介して連結されていることが、好ましい。
この構成によれば、隣接する２個のバッテリは、一対の導通部材に相互に異極の端子を係止される。これにより、複数個のバッテリを電気的に直列接続となるように連結することが、バッテリ間を構造的に分離し難く連結することを兼ねることができる。また、分離後の個々のバッテリの運搬・保管などの管理も有効となる。 Similarly, it is preferable that the plurality of batteries constituting the battery unit be connected via a pair of conducting members in which the pole terminals of the batteries are alternately engaged and disengaged.
According to this configuration, the two adjacent batteries are locked to the terminals of the different polarity mutually in the pair of conducting members. Accordingly, connecting the plurality of batteries so as to be electrically connected in series can also serve to connect the batteries structurally in a manner that is not easily separated. In addition, management such as transportation and storage of individual batteries after separation is also effective.

本発明の電気自動車は、上記した電気自動車のバッテリ搭載構造を備えたことを特徴とする。The electric vehicle of the present invention is characterized by including the above-described battery mounting structure of the electric vehicle.

【発明の効果】
本発明の電気自動車のバッテリ交換方法および電気自動車のバッテリ搭載構造、並びに電気自動車によれば、バッテリの交換作業において、使用済みバッテリを搭載した状態で、電気自動車の左右両側面に設けた一方の開閉扉から、新たなバッテリを導入して、これを深く導入してゆくことで、旧バッテリを他方の開閉扉から押し出すことができる。したがって、新旧両バッテリの重力方向の移動を伴わずに行えるため、一連の交換作業を一人で作業性よく、しかも安全性を確保した状態で行うことができる。また、充電待ちという事態を生じさせないため、運転者の利便を図り、バッテリの寿命を長く維持することもできる。 [0060]
【Effect of the invention】
Battery mounting structure of the battery exchange process, and an electric vehicle of an electric vehicle of the present invention, and according to the electric vehicle, the replacement of the battery, a state mounted with used batteries, one of which is provided on the left and right sides of an electric vehicle The old battery can be pushed out from the other open / close door by introducing a new battery from the open / close door and introducing it deeply. Therefore, since the new and old batteries can be moved without moving in the direction of gravity, it is possible to carry out a series of replacement work with good operability and safety. In addition, since the situation of waiting for charging does not occur, the convenience of the driver can be improved and the life of the battery can be maintained for a long time.
