Problems solved by technology

[0003] However, most of the design ideas for electric vehicle battery packs are to design a set of suitable boxes according to the structure of the whole vehicle. The structure of the whole vehicle and the battery pack are independent of each other. The battery placement structure is relatively simple, which leads to problems such as high cost of battery pack design and complicated assembly methods

Embodiment Construction

[0026] A prismatic battery pack based on a honeycomb structure of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0027] Prismatic battery packs based on honeycomb structure, such as Figure 1-7 As shown, it includes a bottom plate 6, a single battery and a cover plate 4. The bottom plate 6 is provided with a honeycomb groove 61 for installing the single battery, and the single battery is installed in the honeycomb groove 61 to form a honeycomb arrangement. , the cover plate 4 covers the upper part of the single battery, and presses the single battery into the honeycomb groove 61 . The single battery includes at least one battery 2 , a battery holder 1 and a heat management tube 3 , the battery holder 1 is provided with a mounting groove, and the battery 2 is installed in the installation groove of the battery holder 1 . Two or more batteries 2 are installed in the installation groove, and the two or more batt...

Abstract

The invention discloses a square battery pack based on a honeycomb structure. The square battery pack comprises a bottom plate, battery cells and a cover plate, wherein honeycomb grooves for mountingthe battery cells are formed in the bottom plate, and the battery cells are mounted in the honeycomb grooves to be arranged in a honeycomb shape. The cover plate covers the upper parts of the batterycells, the battery cells are tightly pressed in the honeycomb grooves, and heat management tubes sequentially penetrate through multiple adjacent storage grooves of the battery cells and are mounted in a bent manner along the storage grooves of the adjacent battery cells arranged in the honeycomb shape. The square battery pack has the advantages as follows: a battery cell system is combined with achassis or vehicle bottom plate structure, the whole vehicle space is saved, and the square battery pack is applicable to various vehicle model chassis. Layered cover plate design is adopted, power supply connection and a management system can be combined, and effective isolation of strong and weak current can be guaranteed.

Description

【Technical field】 [0001] The invention relates to the field of battery systems for new energy electric vehicles, in particular to a square battery pack based on a honeycomb structure. 【Background technique】 [0002] At present, electric vehicle battery pack systems at home and abroad can be mainly divided into two categories: (1) battery box type; this type is mainly based on the structure of the vehicle, and a set of boxes corresponding to the structure of the vehicle is designed, and the battery is placed in the In the box, the battery can be fixed in the battery box, and at the same time, functions such as monitoring and management of the battery performance are realized. At present, many large electric vehicles in our country adopt this structure. When using this kind of battery pack, priority should be given to reserving a space for it in the vehicle design, that is, the vehicle design must be coordinated with the battery pack structure. (2) Vehicle structure compatib...
