Summary

The energy storage battery industry has experienced rapid development in recent years, especially with the continuous growth of wind and photovoltaic installed capacity and the acceleration of 5G base station construction, the demand for energy storage lithium batteries has grown rapidly. In 2023, the shipment volume of lithium energy storage batteries in China reached 206 GWh, a year-on-year increase of 59%. However, prices have significantly decreased, reflecting the fierce market competition environment. For energy storage battery manufacturers, refined management related to improving quality, reducing costs, and increasing efficiency is becoming increasingly important。

Company Overview

A certain energy storage technology Co., Ltd. is mainly engaged in the production and manufacturing of lithium-ion batteries and power batteries. It has been selected as one of the top 500 global new energy enterprises in 2023, and its lithium-ion battery production capacity ranks among the top in the world. It is committed to providing customers with safe, efficient, clean, and sustainable green energy solutions.

Project Background

With the constantly expanding and fiercely competitive market environment, the company is paying more and more attention to improving quality, reducing costs, and increasing efficiency, hoping to enhance management granularity through digitization and improve the company's competitiveness. The company has invested millions of yuan to build information systems such as ERP, MES, PLM, etc. Currently, there is a lack of a data base platform to connect the information system with the data of production equipment, achieving timely and fine-grained management.

Project Proposal

Build a group IoT platform to achieve centralized collection of production data from customers' three factories in Xiamen and Chongqing, and integrate with users' MES systems to achieve a closed-loop production management business; At the same time, reserve the access capability for new equipment and factories to ensure that the system can be used by customers for a long time. Through data statistical analysis, provide real and effective support for customers to improve quality, reduce costs, and increase efficiency.

The main plan is as follows:

Equipment data collection

Through the gateway's multi interface and multi protocol support capabilities, centralized collection and network interconnection of all production equipment in the front, middle, and back stages such as coating, rolling, winding, Mylar packaging, liquid injection, helium detection, and packaging can be achieved.

Data statistical analysis

By collecting production equipment data, analyze the reasons for equipment OEE, alarms, and shutdowns, and improve equipment management level; Improve quality inspection efficiency by collecting and manually inputting testing equipment data; By analyzing the quality data of cathode coating, identify quality issues and achieve process optimization.

Docking with MES

Integrate the collected data on equipment status, alarms, energy consumption, quality, etc. into MES to achieve a closed-loop management of MES equipment, quality, and energy management business, and improve management timeliness and accuracy

Expected returns

• Improving production efficiency: With the rapid growth of the energy storage market, production efficiency has become the key to enterprise competitiveness. The IoT platform can monitor equipment and processes on the production line in real time, automatically collect, summarize, and analyze data, thereby improving production efficiency and reducing downtime.
• Quality control: The quality of energy storage batteries is directly related to the performance and safety of the product. The IoT platform can monitor key parameters in real-time during the production process, ensuring that each batch of products meets quality standards and reducing the occurrence of defective products.
• Automation and Intelligence: Through IoT platforms, factories can achieve higher levels of automation and intelligent production. This not only reduces labor costs, but also optimizes production processes and improves resource utilization through intelligent algorithms.
• Energy management: Energy storage battery production factories themselves are also major energy consumers. IoT platforms can monitor energy usage, help businesses achieve energy optimization, and reduce operating costs.
• Data driven decision-making: The vast amount of data collected by IoT platforms can be used for in-depth analysis, helping businesses make more accurate market forecasts, production planning, and strategic decisions.
