A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.

Battery thermal management

A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.

A control system of a vehicle includes a network, a first control module, and a second control module. The first control module measures a voltage of a battery of the vehicle and supplies power from the battery to an actuator of the vehicle based on commands received via the network. The second control module is external to the first control module, transmits the commands to the first control module via the network, and, in response to diagnosing a loss of communication with the first control module, controls an alternator of the vehicle to increase the voltage of the battery. In response to diagnosing a loss of communication with the second control module, the first control module supplies power to the actuator based on predetermined data stored in the first control module.

Control systems and methods for loss of communication

A vehicle includes a movable panel having an electronic device; a power source; a data source; and a connector configured to selectively couple the movable panel to the vehicle. The connector is configured to be electrically coupled to the power source and the data source, and is further configured to inductively couple the electronic device of the movable panel to the power source and the data source.

Induction powered panels

Vehicles and systems are provided. In accordance with one embodiment, for example, the vehicle may include, but is not limited to, a moveable panel comprising an electronic device, a power source, and a connector configured to selectively couple the movable panel to the vehicle, the connector configured to be electrically coupled to the power source and further configured to inductively couple the electronic device of the moveable panel to the power source.
