Abstract

The invention discloses a battery matching a VDA module. The battery comprises an aluminum plastic film package and a battery laminate packaged in the aluminum plastic film package, wherein a batterypositive electrode tab and a battery negative electrode tab on the battery laminate extend out of the two ends of the aluminum plastic film package; the two ends of the aluminum plastic film package form a first top sealing edge and a second top sealing edge respectively corresponding to the battery positive electrode tab and the battery negative electrode tab; the first top sealing edge is provided with chamfered structures at the end corners on the two sides of the battery positive electrode tab; and the second top sealing edge is provided with chamfered structures at the end corners on thetwo sides of the battery negative electrode tab. The battery is optimized in the length dimension when distributed in a prescribed VDA module by providing the chamfered structures on the top sealing edges, thereby improving the capacity and the specific energy of the battery and improving the cruising ability of the electric vehicle..

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a battery matching a VDA module. Background technique [0002] The German Automobile Industry Federation (VDA) promulgated and formulated the size test conditions and size standards for power batteries on the basis of summarizing the experience of well-known car companies with international influence, such as Volkswagen, Mercedes-Benz, and BMW. Volkswagen has assembled modules according to the VDA regulations for square PHEV2 batteries and soft pack BEV1 batteries, commonly known as VDA standard modules, which have the advantages of flatness, standardization and scale, and have been recognized by the industry. [0003] Based on the fixed size of the VDA module, focusing on the improvement of energy density, the battery design gives full play to the utilization space of the VDA module. Each battery manufacturer has designed a flexible package lithium-ion battery with...
