Battery and battery pack

Abstract

The invention relates to a battery, comprising an end cap, a casing, an electric core, a pole ear, a pole column and a busbar, wherein at least one port is formed on the casing, and the port is covered by the end cap with a through hole; the electric core is mounted in the casing, the electric core is connected with the pole ear, the pole ear is arranged in the casing, the pole ear is connected with the pole column, the pole column extends from the casing by the through hole on the end cap, and the external side of the pole column is connected with the busbar; and the casing is in a cylindrical shape, and heat radiation convex ribs are formed on the external wall of the casing. The invention further discloses a battery set, which is assembled by a plurality of the batteries through a module support plate, and the through holes for installing the batteries are arranged on the module support plate. The battery has advantages of good heat radiation effect, good tightness, good security, long service life, waterproof and dustproof characteristics, simple assembly and low cost.

Description

[0001] The patent application for this invention is accepted by the State Intellectual Property Office of the People's Republic of China. Application number: 201110032586.6, application date: January 28, 2011, applicant: Wang Weixi, invention name: a divisional application for a battery and battery pack. technical field [0002] The invention belongs to the technical field of battery manufacturing. Background technique [0003] 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: [0004] 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. [0005] 2. The sealing performance is a...

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

[0005] 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.
