The PCM enhanced heat insulation temperature control device for the thermal battery comprises a wrapping layer (1), the interior of the wrapping layer (1) is of a cavity structure, a battery stack is arranged in the cavity structure, and a battery shell is arranged outside the wrapping layer (1); a PCM layer (2) close to the battery stack and a heat insulation layer (3) close to a battery shell are arranged in the wrapping layer (1). The thickness of the wrapping layer ranges from 0.05 mm to 0.15 mm, the thickness of the PCM layer ranges from 0.1 mm to 1.0 mm, and the thickness of the heat insulation layer ranges from 1.8 mm to 3.0 mm. The melting point of the PCM material ranges from 500 DEG C to 650 DEG C, and the heat of fusion ranges from 300 J/g to 700 J/g. According to the device, redundant heat in the early stage of battery activation is stored through the sensible heat storage effect and the latent heat storage effect of the PCM layer and is released in the later stage of work, ...
