Abstract

The invention discloses a battery module and a new energy automobile. The battery module comprises a frame structure; the frame structure is internally provided with a plurality of electric core units in an arraying manner; each electric core unit comprises a monomer electric core, a heat conduction sheet and a heat insulation sheet; each monomer electric core has a positive electrode ear and a negative electrode ear on at least one end part; one side of each heat conduction sheet is provided with the monomer electric core for conducting electric core heat, and the other side of each heat conduction sheet is provided with the heat insulation sheet for preventing heat transfer between the monomer electric cores of the adjacent electric core units. The battery module has high heat transfer efficiency and high cooling and heating efficiency of a battery pack.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a battery module. [0002] The present invention also relates to the field of new energy vehicles, in particular to a new energy vehicle equipped with the above-mentioned battery module. Background technique [0003] At present, the power battery module, especially the flexible packaging power battery module, has a complex structure and difficult assembly, and the fixing method of multiple bolts causes problems such as high cost and low production efficiency. The design is not universal, and the mods cannot be extended. In addition, in order to meet the needs of high-power charging and discharging, the battery cells need to be able to transfer heat to the heat exchange interface in a timely and efficient manner. At the same time, in order to avoid the thermal influence between the battery cells when the module is abused or a single battery cell is damaged, Thermal isolation is al...
