understand the power battery module of power battery module and PACK

Since 1990,the lithium battery because of its high energy density, high voltage, environmental protection, and the advantages of long life and fast charging, by 3 c digital, power tools, and other industries, especially the contribution to the new energy automotive industry is particularly prominent.As a new energy vehicles to provide power source of lithium battery industry market potential is tremendous, is not only an important part of national strategy development, in the next five to 10 years, the industry chain will achieve self-improvement and development of ecological industry, industry scale is expected to exceed 160 billion yuan.

As we all know, the batteries from lithium battery monomer to automation module to PACK in the whole process of production line, assembly line automation is an important factor to determine product quality and production efficiency.In recent years, with the increase of experience and ability of the integrated automation, domestic high-end intelligent equipment manufacturing enterprises in the building power battery automatic/semi-automatic assembly line, automation equipment integration, information collection and transmission (MES), unmanned workshop to make hardware and software aspects such as management system and a place.

This article from the domestic battery module and PACK the equipment characteristics and market demand, the introduction and analyses of the current market forms.

The battery module,

Lithium battery module is made up of a few to hundreds of battery core through the parallel and series of multiple modules, in addition to the mechanism design part, plus the battery management system and thermal management system can form a relatively complete system of lithium battery pack.In general, whether it's soft package, square, cylindrical or type 18650 batteries, module of the automatic assembly process is started with batteries feeding.Packing material can be the original suppliers, also can be factory unified arrangement good special tray after testing.Feeding process can be a manual operation, can automatically by the conveyor belt feeding, and then through the robot through the gripper fetching.Feeding for batteries at the same time also will read code () the identity of a single cell data information, cell polarity detection (whether to put in the opposite direction), cell separation and distribution group, and bad product.Material after the initial inspection and sorting, depending on the module and technological requirements will be separately, such as laser cleaning - glue - batteries stacked - battery pack assembly - pole ear cutting plastic laser welding - module - module shell laser code - a screw - module testing - connecting sheet laser welding - BMS system connection module testing module blanking process, etc.

Lithium battery module,

At present, due to the different among car makers on the market demands, almost none of the module and production process is the same, and it also puts forward more requirements on automatic production line.Good automatic production line in addition to meet the hardware configuration and technical requirements mentioned above, also need to focus on compatibility and "the whole line rhythm".As a result of the module is not fixed, therefore, the incoming batteries, shell, PCB, connecting pieces and is subject to change, compatibility of the production line also is particularly important.For the current power battery industry, the module of the requirements are relatively high degree of automation, and because of the complexity of the technics, the requirement of working environment, etc., the advantage of application of robot and special equipment is obvious.

The battery PACK

PACK is the meaning of packaging, packaging, assembly, the process is divided into three most processing, assembly, packaging.PACK production line generally only need to take two functions: transmission and detection.Manufacturers at present, the commonly used the PACK of semi-automatic assembly production line, mainly used to PACK the upline, downline, detection and transmission in factory and packaging.

Battery manufacturers focus

Last year, published by the ministry of industry lithium ion batteries conditions of industry specifications about the scale of production and technology requirements clearly in the "enterprise should adopt advanced technology, energy conservation, environmental protection, security and stability, high degree of automation of production process and equipment", has also asked the manufacturer to speed up the formulation of power battery product performance, coding, size, and a series of standards.Countries, therefore, in the aspect of promoting the coordinated development of new energy automotive industry chain of the confidence and determination.

At present, power battery is widely present a small batch more varieties of the market characteristics, lack of unified production shows that the industry standard.If the battery is the lack of generality and is unable to achieve standardization, large-scale production, and this aeriform in also increases the production cost of the battery.At the same time, due to differences, such as battery charge and discharge performance index for charging pile also presents the diversified and customized features, so that the battery production, system integration enterprise, the enterprise and the battery recycling enterprises are eager to further unified specification size, so the power battery standards implementation sooner rather than later.

Two big market form

With the improving of the automation of power battery assembly process and the popularity of high-end equipment, power battery enterprises awareness of it more and more is also high.Last year, the domestic companies have configured automatic module production lines, production capacity and product quality has been significantly expand and improve.

In terms of market demand, the battery module and PACK from the current production equipment form small batch more varieties to future mass standardization, the solution of the focus will be the battery manufacturers, at the same time, the battery companies choose automation module and PACK production line, not only for the investment and return, but also the strategic layout of enterprise long-term development.
