Abstract
A system for a vehicle includes an electrical port that charges a vehicle battery via a connection to a power source, and a controller configured to interrupt charging and to display an alert responsive to temperature at the connection being greater than a threshold and voltage of a control pilot terminal of the port being at an overtemperature state voltage that is different from each of disconnected, connected, ready, and fault state voltages.
Claims19
A system for a vehicle comprising:
- an electrical port that charges a vehicle battery via a connection to a power source;
- and
- a controller configured to interrupt charging and display an alert responsive to temperature at the connection being greater than a threshold and voltage of a control pilot terminal of the port being at an overtemperature state voltage that is different from each of disconnected, connected, ready, and fault state voltages.
A method for a vehicle comprising:
- interrupting, by a controller, charging of a traction battery via a connection to a power source to issue an alert responsive to temperature at the connection being greater than a threshold and voltage of a control pilot terminal being an overtemperature state voltage that is different from each of connected, disconnected, fault, and ready state voltages.
A charging cord for a vehicle comprising:
- electrical terminals that cooperate with corresponding terminals of the vehicle and a power source to complete an electrical circuit therebetween;
- and
- a controller configured to, responsive to temperature of the power source terminals being greater than a threshold, interrupt charging and set voltage of one of the terminals to an overtemperature state voltage to cause the vehicle to issue an overtemperature notification.
