ENERGY MANAGEMENT SYSTEM FOR A HYBRID-ELECTRIC VEHICLE
First Claim
1. An energy management system for a vehicle, the system comprising:
- a heating, ventilation, and air conditioning (“
HVAC”
) device configured to heat or cool an occupant compartment of the vehicle;
a thermal storage device configured to heat or cool the occupant compartment, the thermal storage device comprising a first energy storage material adapted to store thermal energy at a high temperature and a second energy storage material adapted to store thermal energy at a low temperature;
an electrical storage device; and
a controller configured to receive electrical power from an electrical generating device, the controller connected to the thermal storage device, the electrical storage device, and the HVAC device and configured to store the electrical power in at least one selected from the group consisting of the electrical storage device and the thermal storage device;
wherein the HVAC device and the thermal storage device are configured to heat or cool the occupant compartment based on at least one of thermal requirements of the occupant compartment, a thermal storage level of the thermal storage device, or an electrical storage level of the electrical storage device.

Abstract
Some embodiments provide a system for optimizing electrical power management in a vehicle. The system includes a HVAC device and a thermal storage device, both configured to provide heating and cooling to an occupant compartment of the vehicle. The system further includes a controller connected to an electrical storage device and an electrical generating device. The controller receives electrical power generated by the electrical generating device and directs the electrical power to satisfy the vehicle'"'"'s power requirements and/or stores the electrical power in at least one of the electrical storage device and the thermal storage device. Furthermore, the controller directs at least one of the HVAC device and the thermal storage device to provide heating and cooling to the occupant compartment of the vehicle, depending on the available storage of the thermal storage unit or occupant compartment demands.

10. A method for providing conditioned air to an occupant compartment of a vehicle, the method comprising:
-
receiving electrical energy from a power generating device; monitoring a thermal storage level of a thermal storage device; when the thermal storage device has available storage capacity, storing at least a portion of the electrical energy in the thermal storage device by; causing the at least a portion of the electrical energy to be converted into thermal energy; and storing the thermal energy in the thermal storage device; when the thermal storage device has inadequate available storage, storing at least a portion of the electrical energy in an electrical storage device; and providing conditioned air to the occupant compartment of the vehicle based on at least one of thermal requirements of the occupant compartment, the thermal storage level of the thermal storage device, or an electrical storage level of the electrical storage device; wherein the conditioned air is provided to the occupant compartment of the vehicle without directing an HVAC device to provide the conditioned air to the occupant compartment when the occupant compartment can be sufficiently heated or cooled by the thermal storage device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
