An integrated vehicle and battery thermal management system for an electric work machine may include a battery module, a radiator, a fan to move air across the radiator, a battery coolant loop including a coolant pump, a refrigerant loop including a compressor, and a chiller providing heat transfer from the battery coolant loop to the refrigerant loop. A controller is operably connected to the coolant pump, the compressor and the fan and is configured to provide a passive cooling mode, a semi-passive cooling mode, and an active cooling mode, dependent upon monitored temperatures in the system.
