Hydronic occupant zone heating and cooling

A vehicle, comprising:

• an occupant zone, wherein the occupant zone is partially located exterior to the vehicle;
• a battery;
• a battery heating and cooling system including 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;
• sensors, operatively connected to a battery management system and including at least one occupant sensor that senses the presence of an occupant in an occupant zone;
• and
• the battery management system including:
• at least one processor;
• and
• a memory including instructions, which when executed by the at least one processor, cause the battery heating and cooling system to:
• operate the refrigeration circuit to heat or cool coolant circulating though the battery heating/cooling loop to heat or cool the battery toward a target battery temperature;
• receive an indication to provide ancillary heating or cooling to the occupant zone;
• determine, based at least on the presence of an occupant in the occupant zone, that conditions are met for providing ancillary heating or cooling;
• and
• direct the coolant circulating though the battery heating/cooling loop to the hydronic system heating/cooling loop to heat or cool the occupant zone.
