Abstract

The invention relates to the field of lithium batteries, in particular to an efficient power battery module, which comprises an outer frame, a plurality of batteries disposed in the outer frame, and aconnector for connecting the plurality of batteries in series. The outer frame comprises two parallel side plates, two end plates connected to the two ends of the two parallel side plates and a plurality of partition plates which are arranged between the two side plates and parallel to the end plates; the plurality of groups of batteries are partitioned through the partition plates; and the outerframe further comprises a heat conducting plate which is arranged on the inner side of the partition plate and attached to the batteries. The efficient power battery module in the invention is convenient for installation, good in stability and strong in reliability and facilitates reduction of potential safety hazards.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a high-efficiency power battery module. Background technique [0002] The battery module is a battery pack formed by connecting multiple power battery cells in series or in parallel, so that the whole can meet the power demand of the product. Today, my country has the world's largest power battery industry. Power lithium battery packs are the core components of new energy vehicles, and their performance is undoubtedly the key to the healthy development of the new energy vehicle industry. Since electric vehicles need high voltage to drive various components in the vehicle, hundreds or even thousands of single cells need to be connected in series and parallel to form a battery pack to meet the power supply requirements of electric vehicles. Among the currently commonly used battery types, lithium-ion batteries are used in new energy vehicles because of their advantages such as hig...
