Release Date: March 2025 (to be adjusted based on actual project timeline)

Project Location: China Building Technology Expo, Shougang Park, Beijing

System Scale: 100kW/215kWh Integrated Solar-plus-Storage System

Core Technology: EXENCELL 280Ah LFP Battery Cell

At the intersection of the "Dual Carbon" goals and urban regeneration, buildings are transforming from "energy consumers" into "energy producers." Recently, a demonstration project integrating building-integrated photovoltaic (BIPV) with an energy storage system officially debuted at the China Building Technology Expo in Beijing's Shougang Park. With core energy storage equipment and battery cells supplied by EXENCELL, the 100kW/215kWh integrated system creates a tangible and replicable "energy showroom" for the large-scale application of BIPV.

When Buildings Generate Power, Why Is Storage Essential?

Walking through the expo, the dark blue photovoltaic curtain walls serve not only as the building's "skin" but also as invisible generators. However, the inherent intermittency of solar power—peak generation hours may not align with peak building consumption, and generation ceases entirely at night—creates a natural gap between "generation" and "utilization."

This is where energy storage delivers value:

Temporal Peak Shifting, Green Energy On Demand

During the day, surplus power generated by the PV curtain walls is automatically stored. In the evening when the expo closes or during cloudy weather, the stored energy discharges to power exhibition equipment and lighting, enabling "time-shifted" utilization of green electricity.

Grid Interaction Flexibility, Enhancing Building Energy Autonomy

Acting as a buffer between the building and the grid, the storage system smooths PV output fluctuations, reduces grid impact, and supports island-mode operation, allowing the building to function independently in specific scenarios.

Exhibition Integration, Making Technology Tangible

As part of the exhibition, real-time operational data from the storage system is displayed on interactive screens, allowing visitors to intuitively grasp "how much solar power is generated, how much energy is stored, and how much the building consumes." This transforms abstract low-carbon technology into an engaging visitor experience.

The Power Core: 280Ah Cells as the Building's Energy Heart

Prismatic Cell (ELEPHENTA)

At the core of this demonstration project lies EXENCELL's independently developed 280Ah lithium iron phosphate (LFP) battery cell—not merely a energy carrier, but the foundation of system safety, longevity, and efficiency:

Intrinsic Safety, Tailored for Building Environments

With limited electrical space and dense occupancy, buildings demand the highest safety standards. The 280Ah cell features a highly stable material system and cell-level safety designs, combined with an intelligent thermal management system. It ensures optimal operating temperatures even under Shougang Park's summer heat and winter cold, fundamentally preventing thermal runaway.

Extended Cycle Life, Locking in Life cycle Value

With a cycle life exceeding 8,000 cycles, the storage system requires no cell replacement over a typical 15-20 year building operation period, significantly reducing long-term maintenance costs and securing sustained energy savings for building owners.

High Energy Density, Adapting to Compact Spaces

Within the limited equipment rooms or outdoor spaces at Shougang Park, the 215kWh system is integrated into compact outdoor cabinets, occupying minimal exhibition floor area and perfectly suiting the space constraints of urban renewal projects.

From Exhibition to Application: A Tangible Energy Transition

As a highlight of the China Building Technology Expo, this solar-plus-storage demonstration is more than a collection of technologies—it is a public education platform for energy transition. Throughout the expo, visitors can interact with screens displaying real-time data: "instantaneous PV generation," "storage system charge/discharge status," and "building carbon reduction metrics," witnessing firsthand how "light" becomes "electricity," how electricity is stored, and ultimately how it powers the building.

EXENCELL collaborated closely with all project stakeholders, providing end-to-end services from solution design and equipment customization to on-site commissioning and grid connection, ensuring stable operation throughout the exhibition period and delivering a "visible and tangible" green building experience for industry peers and the public.

A Zero-Carbon Future, One Building at a Time

Shougang Park—an urban regeneration landmark transformed from a steel industrial site—is witnessing every leap forward in China's green building evolution. Energy storage is emerging as the indispensable "energy buffer" and "value amplifier" in this transformation.

In pursuit of the "30·60" goals, EXENCELL will continue to leverage its leading cell technology and system integration capabilities, empowering more buildings, campuses, and urban scenarios—ensuring every kilowatt-hour of green power is better utilized, and every building moves closer to zero carbon.
