摘要：
The invention relates to a method and an apparatus for detecting the point in time of commencement of crystallization of a heat storage material (40), in particular a latent heat storage material, which is supercooled by means of a Peltier element (32). The profile (10) of the current I of the Peltier element (32) is measured. The commencement of the crystallization process in the heat storage material (40) is deduced when a discontinuity (20, 22) which follows a continuous decrease (16) in the current and after which the current (I) increases again (18) is detected in the current profile (10).
