Energy Storage

Utility-Scale BESS

Overview

Solution Overview

Safety, efficiency and battery system lifespan remain core industry challenges for utility-scale energy storage systems. With massive battery arrays operating in complex environments, real-time, precise monitoring and management have become critical to ensuring the reliable operation of energy storage power stations. Our Battery Management System is engineered to address this challenge. Through round-the-clock intelligent monitoring and data analysis, it prevents potential risks and optimises battery performance, delivering comprehensive safety assurance and energy efficiency support for the energy storage system — from individual cells to the grid.

Key Advantages

Applications of Battery Management Systems for BESS

Extending Battery Lifespan

A battery management system helps to extend battery lifespan by managing depth of discharge (DoD) and charge/discharge cycles.

Safety Management

Lithium-ion batteries in utility-scale systems are sensitive to overcharging, deep discharging and high temperatures, which can create safety risks. The BMS monitors voltage, temperature and current to ensure safe operation, shutting down charging or discharging if needed.

Proven Track Record

Successful Cases

150MW/600MWh Tarim Oilfield BESS

Located on the desert outskirts of Kashgar, Xinjiang, this 150MW/600MWh energy storage project supports the Tarim Oilfield under China National Petroleum Corporation (CNPC). Gerchamp provides advanced BMS solutions to ensure reliable performance in extreme conditions. Since the project launched, GERCHAMP BMS has safeguarded the safe and efficient operation of 45 energy storage units across 3.42 hectares, enhancing system stability, battery life and overall economic performance.

10MW/20MWh World Rooftop Tibet BESS

Gerchamp’s BMS technology plays a vital role in ensuring the safety and stability of the 20MWh energy storage system in the Tibet Changdu project. Located at an altitude of approximately 4,500 metres, this 10MW station spans more than 389,000 sq m and is part of a wider 500MW/2000MWh deployment with a total investment of RMB 172 million. Our advanced BMS solution is designed to withstand extreme conditions, helping to bridge power gaps during peak demand and support sustainable regional development.

13.5MW/63MWh Brownfield BESS

Our Battery Management System (BMS) successfully supports a 13.5MW/63MWh BESS at a repurposed open-cast mine in Inner Mongolia. Mine dump sites commonly face issues such as elevated terrain, steep slopes, heavy dust emissions from exposed surfaces and severe soil erosion. Add in the dry climate and strong winds, and it can lead to frequent dust storms and environmental concerns. Despite these challenges, our G-BS Battery Management System has proven key to enhancing the safety, reliability, efficiency and availability of the battery storage system. We’re proud to see how our BMS is helping to make this unique project a success, supporting both clean energy and environmental restoration in the area.
