SYSTEM AND METHOD FOR CONTROLLING HEATING IN A HYBRID VEHICLE USING A POWER SOURCE EXTERNAL TO THE HYBRID VEHICLE
First Claim
1. A system for controlling heating of at least one of an engine and a battery in a hybrid vehicle using a power source external to the vehicle, the system comprising:
- an electrical port on the vehicle configured to receive electric power from the power source;
an engine heater and a battery heater, both being in the vehicle and electrically coupled to the electrical port;
a system controller in the vehicle configured to generate at least one heater control signal; and
at least one heater switch configured to receive the heater control signal to control an amount of energy transferred from the electrical port to at least one of the heaters.

Abstract
A system and method for controlling heating of at least one of an engine and a battery in a hybrid vehicle includes at least one heater and at least one system controller. The system controller receives a command signal and generates a heater control signal based on the command signal. The heater is in the hybrid vehicle and is electrically coupled to an electrical port integrated in the hybrid vehicle. The electrical port receives electric power from a power source external to the hybrid vehicle. In addition, the system includes a heater switch. The heater switch receives the heater control signal to control an amount of energy transferred from the electrical port to the heater and the heater selectively heats at least one of the engine and the battery in the hybrid vehicle.
