Abstract

The invention relates to a battery module. The battery module comprises several battery monomers and a housing body for accommodating the battery monomers, and a part positioned between the battery monomer and the housing body and between the adjacent battery monomers for absorbing or releasing heat, wherein the part comprises a phase-transition material. The part is a box arranged along the innercircumference of the housing body, and the phase-transition material is packed in the box. The phase-transition material is arranged between the battery monomer and the housing body as well as the adjacent battery monomers, when the temperature is low, the phase-transition material releases heat, and the working ambient temperature of the battery is guaranteed. When the temperature is high, the phase-transition material absorbs heat, the battery heat is effectively transferred, and the safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] The impact of temperature on the battery is manifested in two aspects; in a low temperature environment, such as winter, the battery capacity is reduced, and the temperature in the battery is too low to be conducive to the electrochemical reaction of the battery. The charging and discharging performance of the battery in a low temperature environment is also worse than normal temperature. Even when the battery temperature is lower than a certain value, the battery cannot be charged directly, facing the potential safety hazards of low temperature charging; when the ambient temperature rises, the battery capacity increases, and the chemical reaction inside the battery It is obviously intensified, and the reaction rate and temperature are in a series relationship. The increase in temperature will make the internal resistance of the b...
