Abstract

The invention discloses a battery cover plate. The battery cover plate is shared by a first battery and a second battery which are connected in series. The battery cover plate comprises a negative electrode inner leading-out terminal, an end plate and a positive electrode inner leading-out terminal which are electrically connected in sequence, wherein the negative electrode inner leading-out terminal is electrically connected with a negative electrode of a pole core of the first battery, the positive electrode inner leading-out terminal is electrically connected with a positive electrode of apole core of the second battery, and the end plate is connected with a shell of the first battery in a sealing mode and is also connected with a shell of the second battery in a sealing mode. The invention also relates to a battery system comprising the battery cover plate.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery cover and a battery system including the battery cover. Background technique [0002] With the development of modern society and the enhancement of people's awareness of environmental protection, more and more electronic devices choose rechargeable secondary batteries as power sources, such as mobile phones, notebook computers, power tools and electric vehicles. However, in the field of high-power battery applications, such as new energy vehicles and energy storage, it is often necessary to connect many single batteries in series or in parallel, which also puts forward high requirements on battery cost. [0003] Taking cost reduction as a starting point, it is possible to consider improving the space utilization and energy density of the battery system. At present, many people in the industry are committed to improving the battery structure, but they are basically ba...
