Abstract
A system includes an automatic charging device. The automatic charging device includes a movable arm configured to connect a charging plug head in electric communication with a vehicle inlet of an electric vehicle. The system includes a current detector configured to be in electrical communication with the automatic charging device.
Claims18
A system, comprising:
- an automatic charging device,
- wherein the automatic charging device includes a movable arm configured to connect a charging plug head in electric communication with a vehicle inlet of an electric vehicle;
- and
- a current detector configured to measure an electric current in a charging cable, the current detector being in electrical communication with the automatic charging device,
- wherein the current detector is not in contact with the charging cable,
- wherein the current detector is configured to output current measurements to the automatic charging device.

A system, comprising:
- an automatic charging device,
- wherein the automatic charging device includes a movable arm configured to connect a first charging plug head in electric communication with a vehicle inlet of an electric vehicle;
- and
- a current detector configured to receive a second charging plug head from an electric vehicle supply equipment and configured to be in electrical communication with the automatic charging device,
- wherein the current detector is also configured to measure an electric current in a charging cable of the automatic charging device, the current detector not being in contact with the charging cable,
- wherein the current detector is configured to output current measurements to the automatic charging device.
3 more elements
A method, comprising:
- plugging a charging plug head into an electric vehicle by an automatic charging device;
- detecting, via a current detector, an electric current in a charging cable of the automatic charging device indicative of an initiation of a charging sequence between an electric vehicle supply equipment and the electric vehicle;
- monitoring, via the current detector, a charge state based on current measurements;
- and
- in response to determining that a current supplied by the charging sequence is below a threshold value, outputting an indication to the automatic charging device that a charging sequence is complete;
- wherein the current detector is not in contact with the charging cable.
