Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery mounting method for an electric vehicle. A conventional electric vehicle has a built-in battery and uses all the power of the battery as a source of all operations. The battery is charged by a built-in or external charger in the electric vehicle. In the case of the built-in charger, power is obtained from a household outlet using a cord reel or the like. In the case of an external charger, remove only the battery and bring it to the place where the external charger is located. Until now, the battery could not be charged unless there was an outlet near the electric car body or a charger. Therefore, when using an electric vehicle, it is necessary to prepare an external charger in advance where charging is to be performed, or to separately prepare an outlet in an apartment or a house where there is no outlet outside, which is inconvenient. . [0003] According to the present invention, even if there is no outlet near the electric vehicle, charging can be performed by bringing the battery to the place where the outlet is located, and the outlet is located near the electric vehicle. In such a case, an object is to provide an electric vehicle that can be charged as it is. [0004] In order to achieve the above object, an electric vehicle according to the present invention includes a battery in a case and a charger for supplying power to the battery. A cord for supplying power from a power outlet is drawn out or connected to the case, a battery cable for connecting power from the battery to the electric vehicle body is connected to a battery connector, and a holder for detachably holding the case is electrically driven. A connector receiver fixed to a frame of the vehicle body and connected to the battery cable is attached to the electric vehicle body. [0005] In order to keep the cords together when not in use, the cords may be wound inside the case using a cord reel or the like. Alternatively, a detachable cord can be used so that the cord can be removed when not in use. If the battery cable and the connector receptacle are replaced by providing a battery connector and a connector receptacle opposite to the case and the holder so that the battery cable and the connector receptacle can be connected at the same time as the attachment and detachment of the case, the attachment and detachment work of the battery cable can be omitted. it can. In order to fix the case to the holder in a state where the case and the holder are joined, a fixing band having one end connected to the holder is provided, and the fixing band is fastened to the upper surface of the case, and the other end is fixed to the holder. It can also be fixed to. Further, in order to reduce an impact when the case and the holder collide at the time of coupling of the case, a buffer material made of an elastic body may be provided between the case and the holder. The portability may be enhanced by attaching a handle to the case as necessary, or by forming a part of the outer shape of the case as a handle. Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the electric vehicle 1 of the present invention includes a cowl 2, a battery 3, a charger 4 for supplying and charging power to the battery 3, a cord 5 connecting the charger 4 to a household outlet, A cord reel 6 for winding and holding the cord 5; a connector 7 for guiding power from the battery 3 to the outside; a case 8 for containing and holding the battery 3, the charger 4, the cord 5, the cord reel 6, and the connector 7; A handle 9 fixed to the upper surface of the case 8, a cord hole 14 for passing a cord through the side of the case 8, a holder 10 for detachably holding the case 8, and a holder 10
And a connector 12 fitted to the connector 7. The case 8 is made of resin or metal, and has a connector 7 provided on the lower surface thereof. The cord 5 is provided so as to be able to be pulled out from a cord hole 14 opened on the side surface of the case 8. When the cord 5 is not used, the cord reel 6 holds the cord 5 so as not to be wound up inside. The battery 3, the charger 4, and the cord reel 6
Are enclosed in the case 8 and a handle 9 fixed to the upper portion of the case 8 allows these sets to be carried freely. The holder 10 is made of resin or metal, and has a connector 12 provided on the lower surface thereof facing upward. Connector 12
When the case 8 is joined to the holder 10, the case 8 is engaged with the connector 7 and is electrically connected to the battery 3. Further, a positioning slope 13 is provided on the inner side surface of the holder 10 so as to correct a displacement when the case 8 is inserted. According to the present invention, when a battery for an electric vehicle is charged, when there is no outlet outside, such as in an apartment, a set of components necessary for charging the battery is included in the case, so that the outlet can be easily charged. You can move to a certain place and charge it. On the other hand, if there is an outlet near the electric vehicle, charging can be performed as before. Therefore, the conditions for purchasing an electric vehicle, which have been limited in the past, are eased, and more people can be given an opportunity to use the electric vehicle.
