In terms of production and equipment
collaboration requirements, because power batteries
are discrete manufacturing, the production process
involves multiple links, long processes and high
standardization difficulties, so it is difficult for the
traditional management mode to meet the
requirements of high-precision quality inspection.
For example, with a large amount of data on a single
battery and low detection efficiency, enterprises
urgently need to optimize the production process and
reduce the defect rate through technologies such as
the Internet of Things and big data. In addition, after
CATL introduced automation equipment in the early
days, it faced the problem of insufficient
compatibility between equipment, and needed to
realize the whole process through a unified platform
(such as MES system) to improve production
efficiency.
From the perspective of the needs of strategic
transformation, digital transformation aims to shift
from "scale expansion" to "quality growth", and build
core competitiveness through technology
empowerment. CATL uses the "cloud-edge-end" AI
defect detection technology to reduce the defect rate
and significantly improve product reliability.
2.4 CATL's Digital Transformation
Process
As a leading enterprise in the global power battery
industry, CATL's digital transformation process is a
model for upgrading traditional manufacturing to
intelligent manufacturing. Its transformation process
can be divided into four key stages, and gradually
realized the leap from "manufacturing" to "intelligent
manufacturing".
2.4.1 System Upgrade stage: Build a Digital
Management Base
In 2014, CATL launched an in-depth cooperation
with SAP, a global enterprise management software
giant, to officially launch its digital transformation.
Through the introduction of core systems such as
enterprise resource planning (ERP), supplier
relationship management (SRM) and customer
relationship management (CRM), the company has
built an integrated information management platform
with ERP as the core, covering three levels: core
business, business support and functional
management (Wang, 2022). This system realizes the
standardization and efficient collaboration of
business processes, such as order management,
supply chain collaboration and comprehensive
informatization of financial accounting. The
application of the SAP system not only improves the
efficiency of internal operations, but also lays the
foundation for subsequent data-driven decision-
making. At this stage, CATL integrated the upstream
and downstream resources of the industrial chain
through the ERP system, promoted the overall
digitalization process of the industry, optimized the
procurement process through data exchange with
suppliers, and enhanced the customer demand
response capability through the CRM system.
2.4.2 Internet of Everything Stage: The
Internet of Things Empowers the
Whole Production Process
In 2015, CATL ranked third in the world in terms of
installed power battery capacity, and began to
comprehensively promote the application of Internet
of Things (IoT) technology. In this stage, millions of
IoT terminal devices are deployed to cover more than
3,600 quality inspection points, and production data
is collected in real time and transmitted to the central
control system to achieve accurate control of the
entire production process. At the same time, the
Manufacturing Execution System (MES) was
introduced to integrate elements such as production
planning, equipment status, and energy consumption,
such as real-time monitoring of equipment failures
and early warnings to reduce downtime. In addition,
through PLM software, CATL has achieved
comprehensive and accurate control of product
design data, process data, manufacturing data, etc.
shortening the product iteration cycle and improving
market response speed (Wu, 2024). The technological
breakthrough at this stage has significantly improved
production efficiency and provided technical support
for the expansion of the global market.
2.4.3 Data Empowerment Stage: Big Data
Drives Decision Optimization
In 2017, CATL's installed power battery capacity
surpassed Panasonic and became the world's first.
With the explosion of data volumes, the company
began to build a comprehensive big data platform and
worked with many enterprises to solve the bottleneck
problem of data storage and analysis. By cooperating
with e Cloud to build an IoT data analysis platform, it
opens up the data channel between remote and local
data centers to achieve secure data transmission and
real-time analysis; At the same time, it cooperated
with Intel to upgrade the MES system and use high-
performance processor technology to increase the
processing power by 50%, supporting the expansion
