Light power battery pack structure

Abstract

The invention discloses a light power battery pack structure which comprises a box body, a battery cell pack module in the box body, a top cover module and a bottom cover, wherein the battery cell pack module is a battery pack module formed by connecting single lithium ion soft package batteries in series through a plastic support, a soaking supporting plate and a connecting assembly, and the softpackage batteries are horizontally distributed in a layered mode; a side soaking plate is arranged between the inner side of the box body and the battery pack module, and sealing design is adopted between the box body and the top cover and the bottom cover; the top cover module comprises a charging socket, a discharging socket, an antenna terminal, a BMS board and a communication module board; and a limiting groove is formed in the upper end of the bottom cover. The structure is stable, the heat dissipation effect is good, the battery cell pack structure is reasonable, the service life is long and the overall structure is compact.

Description

Technical field: [0001] The invention relates to the field of packaging of soft-pack batteries, in particular to a light-weight power battery pack structure. Background technique: [0002] With the development of the new energy vehicle market, my country's new energy vehicles have achieved remarkable development results, and new energy vehicles have been popularized to a certain extent. Under the environment of new energy development, new energy light power vehicles have also been vigorously promoted. The light-duty power battery market includes electric two-wheelers, electric tricycles, low-speed electric vehicles, site patrol vehicles, and small sightseeing vehicles. [0003] In recent years, my country's food delivery and express delivery industry has developed rapidly, and the demand for light power vehicles has increased sharply. Reliable, scientific and safe assembly of light-weight power batteries as core components has always been a particularly important technical...
