A system for cooling a vehicle compartment using a twin cell thermal battery and waste heat. Cool air from the evaporators of a twin cell thermal battery system is used to chill a compartment, such as an icebox in a trunk or a cabin of a vehicle. The energy needed to create the cooling effect for the cool compartment comes directly from the waste heat of vehicle exhaust gas. The system provides for the air conditioning and charging mode to work simultaneously because of a twin cell battery configuration. A thermoelectric generator (TEG) is also provided in addition to the twin cell battery thereby making the system self-powered. The system uses energy that would otherwise be lost to the environment to provide a cooling source within the vehicle.
