Original Abstract Submitted
a battery heating and cooling system may be used to provide ancillary heating and cooling to an occupant zone of a vehicle. the battery heating and cooling system may include a battery heating/cooling loop and a hydronic system heating/cooling loop. upon receiving an indication to heat/cool the occupant zone, a battery management system may cause the battery heating and cooling system to direct coolant to the hydronic system heating/cooling loop to heat/cool the occupant zone toward a target occupant zone temperature. in some examples, the battery heating and cooling system directs coolant to the hydronic system heating/cooling loop during battery preconditioning or while heating/cooling the battery during operation of the vehicle. the target occupant zone temperature may correspond to a target battery temperature.
