Abstract

Disclosed is a charging stand for an electric vehicle, the charging stand including a main body, a door coupled to the main body in such a way as to be opened or closed, and an alarm device generating an alarm if the door is opened, wherein the alarm device has a door sensing unit causing a change in impedance if the door is opened, a controller receiving a signal transmitted from the door sensing unit, and a switching circuit activated by the controller to generate an alarm or store an alarm history, so that the charging stand is advantageous in that the opening of the door can be precisely detected, and the alarm history can be checked later.

Claims

1. A charging stand for an electric vehicle, comprising:

a main body;

an openable/closeable door coupled to the main body; and

an alarm device generating an alarm if the door is opened,

wherein the alarm device includes;

a door sensing unit causing a change in impedance if the door is opened;

a controller receiving a signal transmitted from the door sensing unit; and

a switching circuit activated by the controller to generate an alarm or store an alarm history.

2. The charging stand as set forth in claim 1, wherein the alarm device further includes:

a relay turned on or off by the switching circuit;

a browsing history record unit recording a door opening history according to an on/off signal of the relay; and

an alarm unit generating an alarm according to the on/off signal of the relay.

3. The charging stand as set forth in claim 1, wherein the controller controls a power supply unit if the door is opened while the electric vehicle is being charged, thus shutting of charging power.

4. The charging stand as set forth in claim 1, wherein the door sensing unit is selected from a group consisting of a pattern structure, a connector structure, and a wiring structure, which change impedance if the door is opened.

5. The charging stand as set forth in claim 1, further comprising:

a display unit disposed on a front of the main body to inform a user of a charging fee and a charging amount.

6. The charging stand as set forth in claim 5, further comprising:

a manipulation unit provided at a position around the display unit, and allowing the user to manipulate the charging amount or the charging fee.

7. The charging stand as set forth in claim 1, wherein the controller checks at a predetermined period whether the door is opened or not, thus monitoring and storing a precise event record.
