EVSE coupler locking systems, vehicles, and control logic for managing vehicle charging with broken coupler latches

A non-transitory, computer-readable medium storing instructions executable by one or more processors of a vehicle controller to control charging of a vehicle, the vehicle having a charger port and a battery assembly connectable via the charger port to a charger coupler of a vehicle charging system, the instructions, when executed by the one or more processors, causing the vehicle controller to perform operations comprising:

• receiving a connection signal indicating the charger coupler of the vehicle charging system is inserted into the charger port of the vehicle;
• transmitting, responsive to receiving the connection signal, an activation signal to an actuator device of a coupler locking system of the vehicle to move a locking element of the coupler locking system towards a latching element of the charger coupler;
• receiving, from a position sensing device of the vehicle after transmitting the activation signal, sensor data indicative of a travel position of the locking element;
• determining, using the sensor data, if the travel position of the locking element is displaced from a predefined lock position at which the locking element contacts the latching element;
• and
• transmitting, responsive to determining the travel position is displaced from the predefined lock position, a disabling signal to a vehicle battery charging system of the vehicle to disable charging of the battery assembly.

A motor vehicle, comprising:

• a vehicle body with a passenger compartment;
• a plurality of road wheels attached to the vehicle body;
• a traction motor attached to the vehicle body and operable to drive one or more of the road wheels to thereby propel the motor vehicle;
• a traction battery pack attached to the vehicle body and electrically connected to the traction motor to transmit electrical power therewith;
• a charger port configured to receive a charger coupler of a vehicle charging system and thereby electrically connect the traction battery pack to the vehicle charging system;
• a coupler locking system adjacent the charger port and including an actuator device operable to move a locking element against a latching element of the charger coupler;
• and
• a vehicle controller programmed to:
• receive a connection signal indicating the charger coupler is inserted into the charger port;
• responsive to receiving the connection signal, transmit an activation signal to the actuator device to move the locking element towards the latching element;
• after transmitting the activation signal, receive sensor data from a position sensing device indicative of a travel position of the locking element;
• determine if the travel position of the locking element is displaced from a predefined lock position at which the locking element contacts the latching element;
• and
• responsive to determining the travel position is displaced from the predefined lock position, transmit a disabling signal to a vehicle battery charging system to disable charging of the traction battery pack.
