Abstract
A vehicle includes an occupant zone, a battery, a battery heating and cooling system, sensors, and a battery management system. The battery heating and cooling system includes a refrigeration circuit and a fluid battery circuit, the fluid battery circuit including a battery heating/cooling loop and a hydronic system heating/cooling loop. The sensors include at least one occupant sensor that senses the presence of an occupant in an occupant zone. The battery management system operates the refrigeration circuit to heat or cool coolant circulating through the battery heating/cooling loop. When conditions are met for providing ancillary heating or cooling, the battery management system directs the coolant circulating though the battery heating/cooling loop to the hydronic system heating/cooling loop to heat or cool the occupant zone.
