Problems solved by technology

[0004] In the relevant literature, the assembly of battery modules often has the disadvantages of inconvenient assembly and complicated electrical connections to the cells
[0005] If a lithium battery module described in the Chinese patent document CN208093630U uses an aluminum strip to electrically connect each parallel battery cell in a series unit, and then connects each series unit to form a series connection through an external electrical connection structure, but it is connected in this way In this way, the cells connected in parallel in a series unit will be unbalanced, which will cause some cells to deteriorate first, thereby affecting the life of the series unit, thereby reducing the utilization rate of those cells that are still in a better state

Abstract

The invention discloses a terminal combination suitable for a modular lithium battery module, and the terminal combination comprises a unit terminal which is used for enabling the battery cell units connected in series in the modular lithium battery module to form electrical connection; a parallel terminal which is used for enabling the battery cell units connected in parallel in the modular lithium battery module to form electrical connection; and a leading-out terminal which is used for enabling one group of battery cell units connected in parallel in the modular lithium battery module to beelectrically connected with the outside, wherein the unit terminal is electrically connected with the parallel terminal, and the parallel terminal is electrically connected with the leading-out terminal. The terminal combination suitable for the modular lithium battery module has the beneficial effects that the welding is avoided, and the battery cell units can be electrically connected while being connected mutually and mechanically.

Description

technical field [0001] The present application relates to a terminal assembly of a battery module, in particular, to a terminal assembly suitable for a modular lithium battery module. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] With the further development of science and technology, lithium batteries have become a very important source of electric energy in new energy vehicles and other fields. A single b...
