Abstract: A storage battery system includes a rechargeable storage battery and a solid heat storage portion. The solid heat storage portion is made of a heat storage material that reversibly undergoes a phase transition with absorption and release of a latent heat between a solid phase and a solid phase at a certain phase transition temperature. The heat storage material causes a solid phase to solid phase state phase transition when a temperature of the storage battery reaches the phase transition temperature to maintain the temperature of the storage battery at the phase transition temperature.

Abstract: A heat storage system includes an energy conversion portion, and a heat storage portion having a heat storage material. The energy conversion portion converts a form of an energy source into another form, and the energy conversion portion dissipates heat through a medium at the same time as the energy conversion. The heat storage material exchanges heat with the medium. The heat storage material stores heat from the medium in a heat storage mode, and the heat storage material dissipates the stored heat to a heating target. The heat storage material exhibits a first solid phase when a temperature of the heat storage material is higher than a predetermined temperature, and the heat storage material exhibits a second solid phase when the temperature of the heat storage material is at or lower than the predetermined temperature.
