In addition, in order to charge two electric vehicles (EVs) simultaneously, the door of the case must be left open. Therefore, when the owner of the electric vehicle EV gets out of the parking lot during charging, the charging cable 100 is stolen, or the child unplugs the power plug of the charging cable 100 from the outlet 20 in a joke. The same problem may occur.

In contrast, in the charging stand for an electric vehicle of the present embodiment, the four outlets 20 can be provided by storing the outlet units 10 in the four storage spaces 8 in the stand body 1, respectively. As shown in Fig. 7A, one stand main body 1 may be provided for each space for parking four electric vehicles EV, thereby reducing the cost for installation. In addition, since the lower front side of the housing body 11 of the outlet unit 10 can be closed individually by the door 13, a plurality of electric vehicles can be secured while ensuring safety such as preventing theft or mischief of the charging cable 100. It is possible to charge (EV) at the same time. In addition, when the outlet unit 10 is not necessarily stored in all the storage spaces 8, for example, when it is installed in the parking lot which has only two parking spaces, two storage of four storage spaces 8 will be carried out. The outlet unit 10 may be stored only in the space 8.

Thus, the charging stand for electric vehicles of this embodiment adopts the structure which mounts and removes an outlet unit 10 freely in the storage space 8 of the stand main body 1, and is increasing in the number of outlets 20.
