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.

A system includes a DC to DC converter coupled with a load, a power source bus coupled with an input of the DC to DC converter, a capacitor coupled in parallel across an output of the DC to DC converter and a controller. The controller may dynamically adjust a bus voltage set point of a bus voltage on the output of the DC to DC converter up or down to prepare for supply of the bus voltage and energy stored in the capacitor to an anticipated load event. The load event may have a load step change that occurs in less than five milliseconds and is greater than about eighty or eighty-five percent of a rated output of the DC to DC converter.

A system and method described herein detects the presence of an unconnected condition in high voltage component cables in an electric or hybrid-electric vehicle having a high voltage battery or energy storage system. The system includes a mechanical motive device, such as a combustion engine, which is used to rotate an electrical machine (E-machine). The rotation of the E-machine induces a sufficient, yet safe, test voltage on the main high voltage cabling of the vehicle. Measurements are taken at various points near the individual high voltage components to determine if a high voltage cable has become disconnected.
