Problems solved by technology

Power battery grouping technology is a key technology for the development of the electric vehicle industry. Traditional battery grouping methods often have complex structures and poor battery pack strength. They are relatively single for vehicle models, resulting in high development costs and poor structural strength of battery packs. There are many hidden dangers such as battery pack breakdown

Abstract

The invention relates to a battery pack, and particularly relates to a grouped battery pack used in electric vehicles. The technical scheme of the invention is as follows: the grouped battery pack is composed of a plurality of battery packs by clamping; the battery packs comprise cavities made of aluminum alloy materials, and the shape and size of the cavities are matched with the shape and size of cylindrical batteries; the batteries are arranged in the cavities; an outer wall of one side of each of the aluminum alloy cavities is configured with a plurality of grooves, and an outer wall of the other side of each of the aluminum alloy cavities is provided with a plurality of convex ribs; the grooves are matched with the convex ribs; the adjacent battery packs are clamped with the convex ribs integrally through the grooves. The grouped battery pack provided by the invention has the advantages of being simple in structure, low in production cost and good in anti-puncturing effect.

Description

technical field [0001] The invention relates to a battery pack, in particular to a grouped battery pack used by an electric vehicle. Background technique [0002] The battery pack for electric vehicles is based on the load requirements of electric vehicles. It consists of multiple single batteries or super capacitors connected in series and parallel to form a module, and then multiple modules are connected in series and parallel to form a battery pack with a certain voltage and capacity. Power battery grouping technology is a key technology for the development of the electric vehicle industry. Traditional battery grouping methods often have complex structures and poor battery pack strength. They are relatively single for vehicle models, resulting in high development costs and poor structural strength of battery packs. There are big hidden dangers such as battery pack breakdown. Therefore, a new technical solution should be provided to solve the above problems. Content...
