Hydronic occupant zone heating and cooling

A vehicle, comprising:

• an occupant zone;
• 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;
• and
• a 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 conditions are sufficient 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.

A system, comprising:

• at least one processing unit;
• and
• a memory including instructions, which when executed by the at least one processing unit, cause the system to:
• operate a battery heating and cooling system in a preconditioning cycle to heat or cool a battery of a vehicle toward a target battery temperature to charge the battery;
• receive an indication to provide ancillary heating or cooling to an occupant zone of the vehicle;
• determine conditions are sufficient for providing ancillary heating or cooling;
• and
• direct coolant in a fluid battery circuit of the battery heating and cooling system to tubing embedded in a hydronic object in the occupant zone to heat or cool the occupant zone.
