Here, the low temperature warning temperature is a temperature set by the user, preferably 10 ℃.

The core of this technical scheme lies in, temperature sensing formula hot plate 2 is including the casing 3 of assembly in the battery 1 outside, and the inside of casing 3 is stored with heating material 5, and the outside of casing 3 is provided with ventilative opening area, and heating material 5 can be the iron powder, after air passes through ventilative opening area entering casing 3 inside and iron powder, its inside moisture content can take place the reaction with the iron powder, releases heat energy, heats battery 1.

Here, the housing 3 is provided with an access hole, and the reacted iron powder can be replaced.

In order to control the reaction time of the heating material 5, the heating material 5 automatically reacts when the temperature is lower, a shielding unit is arranged on the outer side of the shell 3, the shielding unit does not seal the ventilation opening area when the ambient temperature is lower than the set low-temperature warning temperature, and seals the ventilation opening area when the ambient temperature is not lower than the set low-temperature warning temperature, so that the heating material can be automatically started when the ambient temperature is lower.

The shielding unit can be a combination of the cover plate 7, the temperature sensing sensor and the driving device, when the ambient temperature is lower than the set low-temperature warning temperature, the driving device drives the cover plate 7 to move, so that the cover plate 7 does not seal the ventilation opening area any more.

Herein, referring to fig. 2, the ventilation opening area is a plurality of ventilation holes 6 formed on the housing 3, and the plurality of ventilation holes 6 are in a rectangular array, so that the housing can be uniformly ventilated.

In the technical scheme, in order to reduce the setting of electrical equipment, another structure of a shielding unit is disclosed, specifically, the shielding unit comprises a temperature-sensing material phase-change sheet 9, a cover plate 7 and a resetting piece, wherein the cover plate 7 is arranged on one side of a shell 3 provided with an air hole 6 through the resetting piece, and the cover plate 7 can be driven to continuously move towards the shell 3 through the resetting piece, so that the shell 3 and the cover plate 7 are tightly attached;
