This invention provides a method and an apparatus for automobile warming-up. The apparatus includes a sealed container that is filled with phase changed materials that can form supercooled liquid; a status sensor that monitors the status of the phase change material; a trigger system that induces the supercooled liquid to crystallization; a temperature sensor that monitors the temperature of the phase change materials; and a finned heat exchanger or coiled tube that is connected with the coolant recirculation system of an automobile. After an automobile is ignited, its engine heats the liquid coolant in coolant recirculation system. The heated coolant carries heat energy to the apparatus, which stores the heat energy. When the automobile is started later, the apparatus releases the stored heat energy to heat the coolant, which then warms up the automobile by coolant recirculation system.
