Abstract:
A method for regulating a temperature of a battery having a preferred operating temperature range, the method comprising:providing an amount of phase change material having a phase change temperature within the preferred operating temperature range, the amount of phase change material being in thermal communication with the battery, and a phase change in the amount of phase change material maintaining the temperature of the battery essentially at the phase change temperature; and influencing heat transfer with respect to the amount of phase change material in dependence of a temperature of an ambient medium, the method for influencing heat transfer including; providing thermal insulation between the amount of phase change material and the ambient medium responsive to the temperature of the ambient medium being above the phase change temperature; and providing a transfer of heat from the amount of phase change material to the ambient medium responsive to the temperature of the ambient medium being below the phase change temperature.
