Abstract
Methods, systems, and vehicles provide for cooling of a vehicle rechargeable energy storage system (RESS). A control system is coupled to the RESS, and is configured to cool the RESS. The control system includes a passive cooling system for cooling the RESS, an active cooling system for cooling the RESS, and a controller. The controller is coupled to the passive cooling system and the active cooling system, and is configured to determine whether conditions are present for effective use of the passive cooling system, initiate cooling of the RESS using the passive cooling system if it is determined that the conditions are present for effective use of the passive cooling system, and initiate cooling of the RESS using the active cooling system if it is determined that the conditions are not present for effective use of the passive cooling system.
