The invention discloses a standardized heating function integrated battery module, which includes a casing and a heating device. Used to place the battery module; the heating device includes a first heating body and a second heating body, the first heating body is set in the first installation cavity to heat the battery module in the first installation cavity, and the second heating body is set in the first installation cavity The battery module located in the second installation cavity is heated in the second installation cavity. Realize module standardization, heating function integration, and provide high uniform temperature, high strength and lightweight module structure design. In addition, the "embedded plastic side plate" of the battery module can restrain the deformation of the battery cells in the module. The deformation constraint design can not only limit the normal swelling of the battery core, but also give a certain expansion space to the battery core when an external short circuit occurs, so as to achieve the purpose of prolonging the service life of the battery core.
Description
technical field [0001] The invention relates to the field of automobile battery module technology, in particular to a standardized heating function integrated battery module. Background technique [0002] In recent years, in response to the impact of environmental pollution and the accumulation and consumption of petroleum resources brought about by the rapid development of the automobile industry, all countries are actively conducting research on new energy vehicles. Since the cruising range of new energy vehicles in winter and summer is greatly affected by the environment, the thermal management design of the battery modules of new energy vehicles is a top priority. It is well known that iron-lithium has the advantages of low heat generation, good cycle life and low cost compared with ternary batteries. Too low temperature exceeds the optimal temperature range of the battery, resulting in a sharp decrease in battery life; at the same time, too low temperature will also lea...
