Abstract

The invention provides a heating sheet self-adaptive to deformation and used for an automobile battery, and relates to the technical field of battery heating sheets. The heating sheet comprises a substrate and an outer coating layer, wherein electric heating elements in a path array are arranged between the substrate and the outer coating layer, and the adjacent electric heating elements are connected in series through a wire; the two ends of each electric heating element are connected with an output interface and an output interface through wires respectively; and ventilation openings are formed in the substrate and the outer coating layer and located between the adjacent electric heating elements. According to the invention, air in a sleeve is heated at high temperature to enable the sleeve to expand rapidly, and distance abutting rods at the two ends of the sleeve are pushed towards two sides to drive the electric heating elements on the two sides to move; by increasing the length of a temperature control expansion piece, the number of electric heating elements at a place with a high temperature is reduced, so the temperature rise trend of the heating sheet is reduced; and the number of the electric heating elements at a place with a low temperature is increased, so the heating efficiency of the heating sheet can be improved, self-adaptive heating adjustment is achieved, andlocal temperature is prevented from being too high.

Description

technical field [0001] The invention relates to the technical field of battery heating sheets, in particular to an adaptively deformable heating sheet for automobile batteries. Background technique [0002] The battery is the main component of the car. When the traditional car battery works in a low temperature environment, the capacity and starting current of the battery will decrease by 30%-70%. The starting current will not reach the normal working value, so the engine will not start normally. In view of this phenomenon, it is necessary to set up a battery heating system to heat up the battery. In addition, the energy supply system of new energy electric vehicles (mainly lithium-ion power batteries) also needs to be equipped with a battery heating system. Experimental studies have shown that the most suitable working temperature for lithium-ion power batteries is 10-35°C. In a low-temperature (<-25°C) environment, the charging and discharging performance of the single ...
