High voltage safety lock sensing—single sensor linear actuator
First Claim
1. A safety lock device for locking a charging connector in a charging receptacle of an electric vehicle, the safety lock device comprising:
- a locking pin movable between a first position and a second position;
an actuator configured to drive the locking pin between the first position and second position;
a sensor configured to measure information used in determining a distance the actuator has driven the locking pin; and
a control unit electrically connected to the sensor and configured to receive the measured information from the sensor and determine the status of the safety lock based on the measured information received from the sensor.
