The relay 306 includes a relay contact 306A and an excitation coil 306B, and the charging cable module 200 is connected to the charging cable module 200 from the power supply path 130 via the connection terminal blocks 303 and 304 only while the control circuit 305 supplies an excitation current to the excitation coil 306B. Power is supplied to the terminal block 213, that is, the charging cable 210.

  The control circuit 305 includes a microcomputer and a memory as main components, and realizes a communication function for communicating with the electric vehicle via the communication line of the charging cable 210, a control function for the relay 306 described above, and the like. That is, when charging gun 212 of charging cable 210 is connected to the charging port of the electric vehicle and receives a signal (CPLT signal for starting charging) transmitted from the electric vehicle via the communication line, control circuit 305 causes excitation coil 306B. The relay contact 306A is turned on by supplying an exciting current to the relay contact 306A. When the secondary battery is charged and a signal (CPLT signal for charging completion) transmitted from the electric vehicle via the communication line is received, the control circuit 305 stops the exciting current of the exciting coil 306B. The relay contact 306A is stopped. In addition, the function with which the control circuit 305 is provided is not limited to what performs the conduction | electrical_connection and interruption | blocking of an electric circuit automatically by detecting the said charge start and charge completion. For example, the control circuit 305 has a leakage detection function for detecting a leakage of the charging cable 210 and cutting off the electric circuit, an identification function for determining whether or not to charge the electric vehicle to which the charging cable 210 is connected, and the like. You may prepare.

Another electric vehicle can be charged. That is, according to the charging station of the present embodiment, a plurality of (two in this embodiment) electric vehicles can be simultaneously and safely irrespective of the presence or absence of a dedicated charging cable (charging cable attached to the electric vehicle). Can be charged.

  In addition, since the interlock device supplies power to the outlet 20 only when the door 13 is closed, it is possible to avoid a situation in which a spark (arc) is blown by pulling the plug of the charging cable from the outlet 20 during charging. It is possible to improve safety.

  Further, in the charging stand described in Patent Document 1, a box having no charging function is provided separately from the outlet unit in order to store the charging cable. On the other hand, the charging cable module 200 according to the present embodiment includes a charging cable 210 and a space for storing the charging cable 210, and there is no need to separately provide a space for storing the charging cable 210. The configuration can be simplified.

  In the present embodiment, since the charging cable 210 is connected to the terminal block 213, for example, when the charging cable 210 breaks down, only the charging cable 210 can be removed and replaced, and the maintenance is excellent.

  Furthermore, in this embodiment, the outlet module 10 in which the outlet 20 and the charging cable 210 are stored in the casings 11 and 201 and the charging cable module 200 are detachably stored in the stand body 1. Therefore, the charging cable module 200 and the outlet module 10 can be attached and detached as necessary, and the outlet 20 and the charging cable 210 can be easily added.

  Note that the charge control block 302 of the charge control module 300 can also realize the interlock function of the outlet module 10 instead of the interlock device. For example, as shown in FIG. 9, the interlock switch 18 and the exciting coil 19B of the outlet module 10 are connected to the control circuit 305 of the charging control block 302, and the control circuit 305 is activated when the interlock switch 18 is on. What is necessary is just to supply an exciting current to the exciting coil 19B.
