CALB: Battery cells and systems for vehicles and stationary storage

Overview

CALB develops lithium batteries, battery-management systems and related integrated products. Its catalogue separates passenger vehicles, commercial vehicles, stationary energy storage and other applications. This is a battery-manufacturing business with several routes to market, rather than a single household battery or one standard container product.

The storage references show use in renewable-generation projects and dedicated energy-storage stations. Some entries identify cell platforms, while others describe a complete project's power or energy scale. That distinction matters when comparing suppliers: the capacity of a site is not automatically the capacity of a particular CALB product, and the named battery supplier may cover only part of the site's electrical equipment.

Offering

The energy-storage catalogue identifies an L173F280 platform in a 280 Ah storage-project reference and describes applications using liquid-cooled storage. It also presents multiple project arrangements, including high-power storage and longer-duration renewable-energy applications. The catalogue is useful for identifying CALB's stationary-storage activity and the kinds of installations it serves.

CALB's company profile places those products alongside battery materials and battery-management systems. A procurement brief should specify whether the requested supply is cells, a managed battery assembly or a wider integrated system. That keeps battery capacity, protection, thermal management and the surrounding conversion equipment attached to the actual purchased scope rather than an assumed complete plant.

The current Chinese portfolio also names 314 Ah, 392 Ah, 588 Ah and 684 Ah storage cells, alongside Zhijiu storage and separate traction-battery brands. These are cell and platform distinctions, not interchangeable complete BESS configurations. Manufacturer documentation.

Technology

CALB's research overview describes work across materials, structures and manufacturing, supported by research platforms and collaboration with universities and institutes. Its company profile also identifies battery-management systems as part of the business. These are relevant distinctions for an OEM assessing both the electrochemical product and how a battery assembly is supervised.

The reviewed public pages do not establish a model-specific Modbus, CAN or IEC register/message map for an external controller. No Edge compatibility is inferred from the presence of battery management. For a proposed assembly, the supplier needs to identify its communications interface, accessible measurements, control permissions and the responsibilities of any higher-level energy-management or power-conversion system.

Customers

CALB's published storage references include China Three Gorges, China Resources and TBEA projects. One Three Gorges entry is described as a 150 MW/150 MWh storage station using liquid cooling. The TBEA source-grid-load-storage reference in Ruoqiang County is presented as a 30 MW/60 MWh project. These are manufacturer-reported project examples, not independent performance assessments.

The same page describes installations associated with wind and photovoltaic generation, including sites in Xinjiang and Alxa. Together, the examples show CALB's involvement in utility-scale storage and renewable-energy integration. They also provide concrete project names to investigate when discussing supplier experience, delivery scope and the operating environment relevant to a new development.

Company

A May 2026 shareholder circular identifies the listed entity as CALB Group Co., Ltd., with Hong Kong stock code 3931, and gives its Changzhou address. This is a clearer legal-company reference than expanding the brand name from older third-party descriptions. CALB’s IPO prospectus, in its corporate history section, dates the current company to December 2015. Its former controlling Luoyang company was established in 2009; these are separate legal-company histories.

The company overview describes manufacturing bases across several Chinese regions and expansion into Europe and ASEAN. Its separate passenger-vehicle, commercial-vehicle and storage markets explain the breadth of the product business. For an energy-storage buyer, the relevant comparison is the stationary-storage offering and project supply arrangement, rather than treating the group's entire vehicle-battery portfolio as interchangeable storage equipment.
