Abstract

Embodiments of the invention disclose a lithium ion power battery module and a design method thereof. The battery module comprises a module end plate, an insulating plate, a packing belt and a storagebattery; the battery module further comprises a glued bottom plate; the storage battery is glued to the glued bottom plate; the glued bottom plate comprises a bottom plate heat conduction glue regionand bottom plate structure glue regions distributed on the two sides of the bottom plate heat conduction glue region; each side plate of the storage battery comprises a side plate heat conduction glue region and side plate structure glue regions distributed on the two sides of the side plate heat conduction glue region; the bottom plate heat conduction glue region communicates with the side plateheat conduction glue regions; and the side plate structure glue regions communicate with the bottom plate structure glue regions. On the basis of ensuring the structural strength, the overall temperature of the storage battery module or PACK is reduced, and the temperature difference among different storage batteries is reduced.

Description

technical field [0001] The invention relates to the technical field of battery heat dissipation, in particular to a lithium-ion power battery module and a design method thereof. Background technique [0002] As we all know, in the field of power batteries in the new energy vehicle industry, a reasonable cooling system design is very important. The role of the cooling system is not only to reduce the temperature of the single battery, but also to balance the temperature between the individual batteries. [0003] In order to improve the energy density of PACK (packaging group, packaging package) and take into account the protection standard of IP67, the natural cooling method has become the preferred cooling method for pure electric vehicles, especially pure electric buses and pure electric buses, but the natural cooling heat dissipation efficiency It is very low; and in order to increase the energy density of the power battery, before the commercialization of new materials a...
