Abstract
The present disclosure provides an inlet control system and apparatus for an electric vehicle. It is an object of the present disclosure to provide an inlet control system and apparatus for an electric vehicle that permit the connector of the charging cable to be released from the inlet of the electric vehicle connected thereto only when an authorized user having a release control apparatus is adjacent to the electric vehicle regardless of whether one end of the charging cable connected to a power source is removed or not and prohibit release of the connector of the charging cable from the inlet of the electric vehicle when the user having the release control apparatus moves away from the electric vehicle.
Claims10
A system for controlling locking of an inlet of an electric vehicle, comprising:
- a release control apparatus configured to transmit a release permission signal or a distance signal;
- and
- an inlet control apparatus configured to receive the release permission signal to control the inlet to permit release of a connector of a charging cable connected to the inlet or to receive the distance signal to control the inlet to prohibit release of the connector of the charging cable connected to the inlet when a distance between the electric vehicle and the release control apparatus determined from the distance signal is greater than or equal to a threshold;
- wherein the release control apparatus transmits a time control signal together with the release permission signal or the distance signal;
- and
- wherein the inlet control apparatus maintains a current inlet control state for a time determined using the time control signal.
An inlet control apparatus for controlling an inlet of an electric vehicle depending on whether or not a release control apparatus approaches, the inlet control apparatus comprising:
- a control signal communication unit configured to receive a release permission signal or a distance signal from the release control apparatus;
- and
- an inlet controller configured to control the inlet to permit a connector of a charging cable connected to the inlet of the electric vehicle to be released when the control signal communication unit receives the release permission signal and to control the inlet to prohibit release of the connector of the charging cable connected to the inlet of the electric vehicle when a distance between the release control apparatus and the electric vehicle determined using the distance signal is greater than or equal to a threshold;
- wherein the release control apparatus transmits a time control signal together with the release permission signal or the distance signal;
- and
- wherein the inlet control apparatus maintains a current inlet control state for a time determined using the time control signal.
A method for controlling whether or not to permit release of an inlet of an electric vehicle using a release control apparatus, the method comprising:
- a reception operation of receiving a release permission signal including an identifier of the release control apparatus from the release control apparatus, the reception operation further includes receiving a time control signal together with the release permission signal;
- a determination operation of comparing, when the release permission signal is received, the identifier of the release control apparatus with previously stored identifiers of at least one release control apparatus and determining whether the identifier of the release control apparatus matches any one of the previously stored identifiers of the at least one release control apparatus;
- a control operation of controlling the inlet to permit release of the connector of the charging cable connected to the inlet of the electric vehicle when the identifier of the release control apparatus matches any one of the previously stored identifiers;
- and
- a maintenance operation of performing a control operation to maintain a control state of the inlet for a time determined using the time control signal when the inlet is controlled to permit release of the connector of the charging cable through the control operation.
A method for controlling whether or not to prohibit release of an inlet of an electric vehicle using a release control apparatus, the method comprising:
- a reception operation of receiving a time control signal together with a distance signal from the release control apparatus;
- a comparison operation of determining a distance between the release control apparatus and the electric vehicle using the distance signal and comparing the distance with a preset threshold;
- a control operation of controlling the inlet to prohibit release of a connector of a charging cable connected to the inlet of the electric vehicle when the distance between the release control apparatus and the electric vehicle is greater than or equal to the preset threshold;
- and
- a maintenance operation of performing a control operation, when the inlet is controlled to prohibit release of the connector of the charging cable through the control operation, to maintain a control state of the inlet for a time determined using the time control signal.
