The invention discloses a lithium-ion battery heat insulation device and a control method thereof. The heat insulation device comprises an insulation box for containing a lithium-ion battery, and a temperature control circuit of which the power is supplied by the lithium-ion battery and which is used for controlling the ambient temperature around the lithium-ion battery; and the temperature control circuit is arranged in the insulation box. The temperature control circuit comprises a temperature detection module, an automatic temperature control switch module and a temperature controlling device; the temperature detection module is connected with the automatic temperature control switch module; and the automatic temperature control switch module is serially connected with the temperature control device. The invention solves the problem that an existing lithium-ion battery is seriously restricted by the ambient temperature when being used, so that an ordinary lithium-ion battery can be used normally not only at room temperature but also in cold environment and at high temperature, and the invention has the advantages of simple structure, easiness in manufacturing, convenience in use and good adaptability.
