CALB: The Real Manufacturer Powering China’s EV Revolution — CWC Visits Chengdu Factory

On November 4, China West Connector (CWC) visited the Chengdu factory of CALB Group Co., Ltd. (Stock Code: 3931.HK) — a true global manufacturer leading the future of energy technology.

CALB: A Real Manufacturer, Not an Integrator

In today’s fast-growing battery market, many companies present themselves as “manufacturers” but are in fact integrators — sourcing and assembling cells and components made by others.

CALB is fundamentally different. It is a real, full-chain manufacturer, producing everything from core materials and cells to battery modules and complete energy systems within its own facilities. Its manufacturing process is fully controlled, vertically integrated, and supported by more than 6,000 patents and 100% proprietary technologies.

This deep in-house capability is the reason CALB has earned its position as No. 3 in China and No. 4 globally in EV battery installations.

Powering Nearly Every Major EV Brand

CALB’s advanced batteries are used by almost every leading Chinese and international carmaker — including NIO, XPENG, Geely, Chery, GAC AION, Toyota, Mazda, and Volvo.
Over 37 car brands and more than 300 models rely on CALB’s systems, covering every segment from compact urban EVs to luxury and high-performance vehicles.

This makes CALB not just a supplier, but a key industrial force behind China’s new-energy vehicle revolution.

Beyond Cars: The Power Behind Energy, Transport, and the Sea

CALB’s technological reach extends well beyond passenger cars. The company manufactures complete battery systems for commercial trucks, buses, trains, ships, and large-scale energy storage.

These systems power electric logistics fleets, rail transport, marine vessels, and renewable energy grids, confirming CALB’s capability to serve the entire mobility and energy spectrum — on land, at sea, and across industrial networks.

Chengdu: The Heart of CALB’s Advanced Manufacturing

CWC’s visit to the Chengdu base highlighted CALB’s world-class manufacturing standards and its deep investment in research and development.
The Chengdu factory is not just a production site — it’s a strategic innovation center focusing on next-generation energy-storage materials and intelligent manufacturing technologies, fully aligned with global goals for green, low-carbon growth.

CWC’s Role: Building Global Bridges for New Energy

For China West Connector, this visit reaffirms its commitment to link Western industries with China’s true innovators — companies like CALB that produce real technology, not just assembled systems.

CWC continues to promote cooperation in electric mobility, green logistics, marine electrification, and renewable energy, helping Western partners access genuine Chinese manufacturing excellence.
