Problems solved by technology

[0003] At present, there are several kinds of battery pack fixing racks on the market. The existing battery pack fixing racks are inconvenient for quick installation and disassembly of single batteries, and at the same time, they cannot match batteries of different sizes and models, which increases the fixed cost. The structure is complex, the fixing strength is poor, there is no heat dissipation structure, or the heat dissipation cannot be effectively exported, thus affecting the safety performance of the entire battery pack

Abstract

The invention belongs to the technical field of lithium ion battery packs, and particularly relates to a battery pack fixing and heat conducting integrated framework structure for an electric motorcycle. The framework structure comprises an outer shell, three bracket groups for fixing batteries, two I-shaped profiles and a plurality of long screw rods, wherein the two I-shaped profiles are respectively positioned among the three bracket groups; through holes corresponding to the long screw rods are formed in the bracket groups and the I-shaped profiles, the long screw rods penetrate through the through holes and are interlocked with bolts, the support groups and the I-shaped profiles are fixedly combined into a whole, and the whole can be contained in the outer shell with openings in the two ends. According to the invention, the battery module is fixed more stably, the influence of temperature on different areas in the battery module is reduced, the problem of pressure difference caused by temperature difference among batteries is effectively controlled, and the service life of the batteries is prolonged.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion battery packs, and in particular relates to a skeleton structure integrating fixing and heat conduction of a battery pack for electric motorcycles. Background technique [0002] At present, most electric vehicle battery packs are composed of multiple batteries in series and parallel to provide the required rated voltage and current. Battery packs are divided into series and parallel. Parallel battery packs require the same voltage for each battery, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide stronger current. For the normal operation of the battery pack, it is usually used The battery pack fixing frame, the advantages of the fixing frame are fixing, insulation, safety, high strength, suitable for the combination of larger modules. [0003] At present, there are several kinds of battery pack fixing racks on the market. The existing battery ...
