Battery pack

Abstract

The invention relates to a battery pack. The battery pack comprises: a box body; a cover body, which covers the box body; a battery assembly, which is arranged in a closed space formed by the box body and the cover body; and an end part assembly, which comprises a panel and two or more connectors fixed on the panel, wherein the battery assembly is electrically connected with a device outside the closed space through the connectors, and the panel is in sealed connection with the box body or the cover body and is fixedly connected with the box body through a bracket. According to the battery pack provided by the invention, the end part assembly integrated with two or more connectors is fixed on the box body through the bracket, and the weight of the connectors is borne by the bracket, so the connectors are not easy to fall off, the probability of sealing failure caused by pulling of the self weight of the connectors is reduced, and the sealing reliability and safety of the battery pack are improved.

Description

[0001] This application is based on the application number 201811361300.7. The application date is November 15, 2018, the applicant is a distribution application for the invention of the invention-called "battery pack" in the Ningde Times. Technical field [0002] The present invention relates to the field of power cell technology, and more particularly to a battery pack. Background technique [0003] With the enhancement of environmental awareness and the low-carbon economy is in the like, new energy vehicles will become the mainstream of future automotive industries. Reducing the height of the vehicle is conducive to reducing the driving resistance of the whole vehicle, thereby saving driving energy consumption. However, the premise of reducing the highness of the vehicle cannot affect the passability and comfort of the vehicle, so the high height of the reduction will be achieved in a manner of reducing the overall height of the power battery, and improving the energy density o...

Problems solved by technology

[0004] In the prior art, the various connectors of the power battery are generally fixed on the casing. When the battery pack is subjected to a large impact, the connectors may fall off the casing directly, causing a short circuit in the electrical connection circuit of the battery, and even causing a fire. ACCIDENT

In addition, the connector has a certain weight. During long-term use, the seal between the connector and the shell will fail due to vibration and other reasons.
