a battery pack

Abstract

The invention relates to a battery pack. The battery pack comprises a fixing frame, a cell group, a shell and nickel strips; the fixing frame comprises a first support and a second support, each of the first support and the second support is in a honeycomb structure and provided with a plurality of lattices, and the lattices of the first support and the second support combined to form a plurality of cylindrical cell cavities; cell individuals are partitioned and put in the fixing frame through the cell cavities, the nickel strips are arranged on two surfaces of the fixing frame respectively and connected with electrodes of the cell individuals, and connection of the cell individuals is connected through the nickel strips. The battery pack is safe, reliable and simple structurally; by partition of the cell individuals through the cell cavities in the fixing frame, isolation and protection effects are achieved, and potential safety hazards including looseness, short circuit and the like caused by violent vibration can be prevented effectively; by series connection and / or parallel connection of the cell individuals through the nickel strips, high-current charging and discharging can be met, and simplicity in processing is achieved due to structural simplification of the battery pack.

Description

technical field [0001] The invention relates to the field of energy storage lithium batteries, in particular to a battery pack. Background technique [0002] With the development of society and the deterioration of the environment, energy storage devices are more and more widely used in people's lives. The energy storage battery is a battery pack module composed of battery cells connected in series or in parallel. The battery pack module is widely used due to its advantages of good scalability and easy installation. The installation of each battery cell inside the existing battery pack usually uses a simple bracket or wraps the battery cell with tape to fix the battery cell. There is no isolation protection between each battery cell, and it will also cause electric shock during strong vibrations. Loose cells cause potential safety hazards such as short circuits. The series and parallel connections between battery cells are often connected by wires, which cannot meet high-cu...

Problems solved by technology

The installation of each battery cell inside the existing battery pack usually uses a simple bracket or wraps the battery cell with tape to fix the battery cell. There is no isolation protection between each battery cell, and it will also cause electric shock during strong vibrations. Loose cells cause potential safety hazards such as short circuits. The series and parallel connections between battery cells are often connected by wires, which cannot meet high-current charging and discharging. The internal energy summary and output terminals are mostly connected by wires, resulting in messy internal structures and complicated processing.
