Described herein is a system for thermal management of a component, such as a battery for an electric vehicle. The system comprises an electrical component and one or more panels thermally coupled to the electrical component. Each panel comprises a plurality of passages for conveying a working fluid around the panel. The one or more panels are arranged to form a hermetically sealed system such that the working fluid is configured to communicate heat energy around the sealed system. The system further comprises a heat exchanger mechanism in thermal communication with at least one of the plurality of panels so as to communicate heat energy to and/or from the electrical component via the plurality of panels.

There is provided a battery cooling control system capable of efficiently and effectively controlling the cooling of a battery. While an electric powered vehicle travels and/or stops, it is determined whether or not there is an indication of a battery being charged, and if it has been determined that there is the indication of charging being performed, it is determined whether or not there is a necessity for cooling the battery, and if it has been determined that there is the necessity for cooling the battery, the battery is cooled to a predetermined value during traveling. In addition, based on at least a state of charge of the battery and/or a driving range, it is determined whether or not there is an indication of charging being executed, and based on a real-time battery temperature, an increase in battery temperature caused by charging, and an upper limit value for a predetermined allowable battery temperature range, it is determined whether or not there is a necessity for cooling the battery.
