Battery and battery pack

Abstract

The invention relates to a battery, which comprises end covers, a housing, an electric core, polar ears, polar columns and conductive strips, wherein the housing comprises at least one port, and the ports are sealed by the end covers with through holes; the electric core is arranged in the housing, the electric core is connected with the polar ears, the polar ears are positioned in the housing, the polar ears are connected with the polar columns, the polar columns extend out of the housing through the through holes of the end covers, and the outer parts of the polar columns are connected with the conductive strips; and the housing is cylindrical, and heat radiation convex ribs are formed on the outer wall of the housing. The invention further discloses a battery pack, which is assembled by a plurality of the batteries through modular support plates, and the through holes for mounting the batteries are formed on the modular support plates. The battery has the advantages of great heat radiation effect, good sealing property, high safety, long service life, waterproof and dustproof properties, assembling is simple assemble, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing. Background technique [0002] The battery is the "heart" of the electric vehicle, and its performance directly affects the performance and quality of the electric vehicle. The batteries of the prior art have the following defects: [0003] 1. The heat dissipation effect is one of the important indicators for evaluating battery performance. The current battery casing adopts a square structure, and the battery of this structure has the defect of poor heat dissipation effect, and is also not conducive to arrangement and assembly into groups. [0004] 2. The sealing performance is also one of the main technical indicators of the battery. A battery with poor sealing performance has low safety and short service life. The structure of the battery end has a great influence on the sealing performance of the battery. However, the end structure of the existing battery still has disadvantag...

AI Technical Summary

Problems solved by technology

The current battery casing adopts a square structure, and the battery with this structure has the defect of poor heat dissipation effect, and it is also not conducive to arrangement and assembly into groups

[0004] 2. The sealing performance is also one of the main technical indicators of the battery. A battery with poor sealing performance has low safety and short service life.

The disadvantages of this structure are: since there is no special protective part at the end of the battery, parts such as conductive strips and poles are easily polluted by moisture, dust, etc., which will affect the normal operation of the battery and reduce its service life. In severe cases, it will cause Battery short circuit, misoperation, etc.

At present, there are some defects in the battery assembly process: for example, battery assembly is time-consuming and laborious; after the battery is disassembled, it cannot be assembled again, so the battery is scrapped and wastes resources; special machines need to be configured, which increases the cost of assembly, etc.
