Abstract

The invention discloses a power battery pack comprising a battery cell tray and an insulating board. The power battery pack is provided with clamping buckles, buckling slots, fixed holes, heat radiating ducts, locating pins and the like, wherein the battery cell tray is provided with an aluminum soldering block and a copper soldering block, the fixed holes are used for better clamping modules, the battery cell locating pins are used for locating battery cores, and the ducts are used for radiating heat; the insulating board is provided with the clamping buckles which are respectively and correspondingly buckled in the buckling slots of the battery cell trays, the insulating board is embedded with four anti-rotation nuts connected with the fixed holes of the battery cell trays, the positive pole and the negative pole of the insulating board are marked, the battery cell trays are tightly matched with the clamping buckles of the insulating board, and the insulating board is fixed on electrical equipment or an electric automobile and the modules are clamped tightly through bolts, thus, a plurality of battery cells with flexible packages can be stably and fixedly connected, and the power battery pack has the advantages of stability in connection, good heat radiating property, space conservation, convenience for battery cell locating, assembling, dismounting and maintaining, small internal resistance for contact, realization of inside wiring, no edge folding of the battery cells, large shape size tolerance range of the battery cores and the like.

Description

technical field [0001] The invention belongs to the technical field of power batteries, in particular to a power battery pack capable of stably fixing a plurality of batteries. Background technique [0002] With the development of society and the enhancement of environmental protection awareness, more and more electric vehicles and other energy devices choose to use batteries to provide power. [0003] In the case of limited energy density of existing batteries, the battery can only be installed on electric vehicles or other energy devices in the smallest space possible. In order to meet the actual use requirements of electric vehicles and other energy devices, it is usually necessary to connect multiple batteries in series and / or in parallel. However, there is currently no battery fixing connection device for stably fixing a plurality of batteries together, that is, there is no power battery pack with a stable fixing structure. Contents of the invention [0004] The pur...
