Abstract

Systems and methods for thermal management are provided. Thermal management components may include an electrical source and a cooling source. The electrical source may supply electricity to an electrical apparatus. In addition, the thermal management components store thermal energy. A controller may cause the electrical apparatus to be cooled by the cooling source and delay or suspend cooling the electrical source with the cooling source while a state of charge of the electrical source is greater than a predefined value for the electrical source. The state of charge of the electrical source may include a measurement of cooling capacity available by the electrical source.
