Abstract

The invention discloses interlaced power cell groups. The interlaced power cell groups comprise unit cells and parallel elements, wherein the unit cells are divided into N groups; each unit cell group has M unit cells; unit cells of the two adjacent unit cell groups have a one-to-one correspondence relationship; M unit cells are connected in series successively; both N and M are integers greater than or equal to 2; both N and M are not equal to 2 at a same time; the parallel elements are divided into e groups; a first end of any parallel element of an eth parallel element group is connected between two adjacent unit cells of the eth unit cell group of an Nth group; a second end of the any parallel element of the eth parallel element group is connected between two adjacent unit cells of an (e plus one)th unit cell group; and the N unit cell groups are made to be connected in parallel through the multiple parallel elements. The interlaced power cell groups have great security and high reliability, can assist in managing precisely every unit cell and have a self-balancing function.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to an interleaved group power battery pack. Background technique [0002] With the continuous development of science and technology, cars have gradually entered ordinary family life. In recent years, global car production and sales have been steadily increasing. At the same time, the global oil resources are depleted and the greenhouse effect is becoming more and more serious. The two major issues of energy and environment have become major challenges for various countries and major automobile manufacturers in the world. Therefore, the development of new energy vehicles that are energy-saving and environmentally friendly It must be done. Among many types of new energy vehicles, electric vehicles (including pure electric vehicles and hybrid vehicles) gradually stand out, and power batteries are one of the most critical components of electric vehicles, but the voltage and cap...
