Embodiment 1

[0071] see Figure 1-Figure 2 In this embodiment, the large-capacity battery in which the pole is connected to the housing includes a housing 1 and a pole body. The pole body includes a positive pole 3 and a negative pole 4. The housing 1 is composed of a housing side wall 5 and a housing bottom. The wall forms a prismatic structure or a cylindrical structure. Preferably, the housing 1 of this embodiment is a quadrangular prism structure. The top of the housing 1 is an opening, and an upper cover plate 2 is arranged at the top opening of the housing 1. The housing The side wall 5, the bottom wall of the casing and the upper cover plate 2 together form a battery accommodation chamber; the positive pole 3 and the negative pole 4 are respectively arranged on the two opposite casing side walls 5 on the casing 1, and extend to the casing the outside of the side wall 5.

[0072] see Figure 5 , the positive pole 3 and the negative pole 4 of this embodiment both include a pole heat...

Embodiment 2

[0094] see Figure 12 The large-capacity battery series structure of this embodiment is formed by connecting the poles of multiple embodiments in series with the large-capacity batteries connected to the housing. Preferably, the large-capacity batteries connected to the poles of this embodiment are The number of batteries is 3, and the large-capacity batteries with two adjacent poles connected to the casing are connected in series through the fastening connection mechanism 22 .

[0095] see Figure 13 and Figure 14 , the fastening connection mechanism 22 of the present embodiment includes a fixed part 221, a push part 222 and a threaded fastener. The fixed part 221 is composed of a vertical connecting rod and a horizontal connecting rod fixedly connected to the vertical connecting rod. The bottom of the bottom is provided with snap-in tongue 225, and the pushing part 222 is a vertical connecting rod arranged parallel to the vertical connecting rod of the fixing part 221, an...

Abstract

The invention provides a pole and shell connected high-capacity battery and a series connection structure thereof, and belongs to the technical field of energy storage batteries. The high-capacity battery comprises a shell and a pole body, and one side part of the pole body penetrates through the side wall of the shell and extends to the outer side of the shell side wall. According to the invention, when a plurality of poles pole and shell connected high-capacity batteries are connected in series, connection can be carried out through the pole bodies extending to the outer side of the side walls of the shells, and no electric wire is needed for connection, so that the problems of winding of the electric wire and many wire ends are avoided; and meanwhile, the pole has relatively large overcurrent, so that current circulation of two adjacent high-capacity batteries can be completely met, and the problem of overburning is avoided.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and relates to a large-capacity battery series connection technology, in particular to a large-capacity battery with a pole connected to a shell and a large-capacity battery series structure. Background technique [0002] As a new energy secondary battery, lithium-ion battery has the advantages of high energy density and power density, high working voltage, light weight, small size, long cycle life, good safety performance, and environmental protection. It is widely used in portable appliances and electric tools. , large-scale energy storage, and power supplies for electric vehicles have broad application prospects. [0003] Especially under the current background of energy saving, emission reduction and carbon neutrality, the demand for lithium batteries in the field of energy storage is in short supply. At present, lithium batteries used in the field of energy storage are most...
