Inlet charging plug detection sensor
A charging inlet for an electric vehicle includes a housing, a terminal arranged within the housing for engaging with a corresponding mating terminal of a charging plug, and a sensor connectable to a monitoring system of the electric vehicle for detecting the presence of a charging plug installed within the charging inlet.
1. A charging inlet for an electric vehicle, comprising:
a housing defining a catch;
a terminal arranged within the housing for engaging with a corresponding mating terminal of a charging plug; and
a sensor connectable to a monitoring system of the electric vehicle for detecting the presence of a charging plug installed within the charging inlet, the sensor detecting the presence of a latch of the charging plug when the latch is engaged with the catch of the housing in an installed position of the charging plug relative to the housing.
2. The charging inlet of claim 1 , wherein the sensor detects the presence of a charging plug independent of an electrical connection between the terminal and the mating terminal.
3. The charging inlet of claim 1 , wherein the housing defines an opening formed therethrough proximate the catch, the sensor detecting the presence of the latch of the charging plug through the opening.
4. The charging inlet of claim 1 , wherein the sensor is arranged within a sensor housing removably attached to the housing.
5. The charging inlet of claim 1 , wherein the sensor includes an optical sensor.
6. The charging inlet of claim 1 , wherein the sensor includes a magnetic sensor for detecting a change in a magnetic field associated with an installed position of the charging plug.
7. The charging inlet of claim 1 , wherein the sensor includes a mechanical switch.
8. The charging inlet of claim 1 , wherein the sensor includes a pair of conductive pins for electrically contacting a conductive surface of the charging plug in an installed position within the housing.
9. A charging system for an electric vehicle, comprising:
a housing;
at least one terminal arranged within the housing for engaging with a corresponding terminal of a charging plug;
a monitoring system including at least one sensor for detecting the presence of the charging plug in an installed position within the housing, the at least one sensor detecting the presence of a latch of the charging plug or the housing when the latch is engaged with a catch of the other one of the charging plug or the housing.
10. The charging system of claim 9 , wherein the sensor detects the presence of a charging plug independent of an electrical connection between the terminal and charging plug.
11. The charging system of claim 9 , wherein the housing defines the catch for engaging the charging plug with the charging plug in the installed position relative to the housing, the sensor positioned to detect the presence of the charging plug engaged with the catch of the housing.
12. The charging system of claim 11 , wherein the housing defines an opening formed therethrough proximate the catch, the sensor detecting the presence of the charging plug through the opening.
13. The charging system of claim 12 , wherein the charging plug defines the latch and the sensor detects the presence of the latch of the charging plug when the latch is engaged with a catch of the housing.
14. The charging system of claim 13 , wherein the monitoring system discontinues a charging operation upon a detection of the absence or depression of the latch.
15. The charging system of claim 9 , wherein the sensor includes an optical sensor.
16. The charging system of claim 9 , wherein the sensor includes a magnetic sensor for detecting a change in a magnetic field associated with the installed position of the charging plug.
17. The charging system of claim 9 , wherein the sensor includes a mechanical switch.
18. A charging inlet for an electric vehicle, comprising:
a housing;
a terminal arranged within the housing for engaging with a corresponding mating terminal of a charging plug; and
a sensor connectable to a monitoring system of the electric vehicle for detecting the presence of a charging plug installed within the charging inlet, the sensor arranged within a sensor housing removably attached to the housing of the charging inlet.
19. The charging inlet of claim 18 , wherein the housing of the charging inlet defines one of a latch or a catch and the charging plug defines the other one of the latch or the catch, the sensor positioned and adapted to detect the presence of the latch engaged with the catch through an opening formed in the housing.
