Abstract

An electric vehicle charging apparatus. The electric vehicle charging apparatus includes an electric vehicle including a vehicle coil connected to a charging circuit connected to a storage battery, a parking stop arranged on a parking lot surface, a stop coil arranged within the parking stop to generate an induced current in the vehicle coil when the vehicle coil is arranged in a vicinity of the stop coil and an operation unit connected to the stop coil to raise the stop coil.

Claims

1. An electric vehicle charging apparatus to recharge an electric vehicle having a vehicle coil connected to a charging circuit connected to a storage battery, the electric vehicle charging apparatus comprising:

a parking stop arranged on a parking lot surface;

a stop coil arranged within the parking stop to generate an induced current in the vehicle coil when the vehicle coil is arranged in a vicinity of the stop coil; and

an operation unit connected to the stop coil to raise the stop coil.

2. The electric vehicle charging apparatus of claim 1, wherein the operation unit comprises a first cylinder member that is arranged within the parking stop.

3. The electric vehicle charging apparatus of claim 1, wherein the operation unit comprises:

a first rack gear arranged within the parking stop to raise the stop coil above the parking stop and to lower the stop coil back within the parking stop;

a first pinion gear that engages with the first rack gear;

a second pinion gear that rotates together with the first pinion gear; and

a second rack gear adapted to move horizontally upon application of force, adapted to protrude from a side of the parking stop and capable of being forced within the parking stop, the second rack gear being engaged with the second pinion gear.

4. The electric vehicle charging apparatus of claim 1, further comprising a sensing unit that senses whether the electric vehicle is parked at a proper location for charging.

5. The electric vehicle charging apparatus of claim 4, wherein the sensing unit is a limit switch that is installed on the parking stop to sense whether a tire of the electric vehicle forms contact therewith.

6. The electric vehicle charging apparatus of claim 4, wherein the sensing unit is a load sensor that is installed on a surface of the parking lot at a location in a vicinity of the parking stop to sense a wheel load of the electric vehicle.

7. The electric vehicle charging apparatus of claim 1, further comprising a vehicle type sensor that senses a vehicle type of the electric vehicle entering into the parking lot.

8. The electric vehicle charging apparatus of claim 7, wherein the vehicle type sensor comprises:

a Radio-Frequency IDentification (RFID) tag that is installed on the electric vehicle to transmit vehicle information; and

an RFID reader that is installed in the parking lot to receive a signal from the RFID tag that includes vehicle information of the electric vehicle.
