Ukraine 160kW / 418kWh Liquid-Cooled Battery Energy Storage Project

In Ukraine, where winter temperatures frequently fall below freezing, GSL ENERGY successfully deployed a 160kW / 418kWh liquid-cooled battery energy storage system (ESS) designed for stable performance in low-temperature environments.

In this project, the inverter was installed indoors while the liquid-cooled battery cabinet was installed outdoors, fully exposed to cold weather. Despite sub-zero ambient temperatures, the system has continued to operate safely, efficiently, and reliably, demonstrating the strength of GSL ENERGY’s liquid-cooled energy storage technology.

This project provides a valuable reference for outdoor energy storage deployment in cold-climate regions.

System Configuration

• ESS Capacity: 160kW / 418kWh

• Cooling Technology: Advanced liquid cooling system

• Battery Chemistry: LiFePO₄ (LFP)

• Installation Mode:

  • Inverter: Indoor installation

  • Energy storage battery cabinet: Outdoor installation

• Application Scenario: Commercial & Industrial energy storage

Low-Temperature Performance of the Liquid-Cooled ESS

During system operation, local ambient temperatures dropped below 0°C, which can create challenges for conventional air-cooled battery systems.

However, the GSL ENERGY liquid-cooled ESS maintained:

• Stable charge and discharge performance in low-temperature environments

• Normal battery temperature control through the built-in heating function

• No abnormal alarms or performance degradation during operation

The system’s intelligent thermal management strategy automatically activates the internal heating mechanism when external temperatures fall, keeping battery cells within an optimal operating range. This improves battery safety, lifecycle stability, and overall system reliability in cold climates.

Advantages of Liquid-Cooled Energy Storage in Cold Regions

Compared with traditional air-cooled systems, liquid-cooled battery energy storage systems offer key benefits in environments with large temperature variations:

• Precise thermal control for each battery module

• Improved temperature consistency and reduced cell imbalance

• Higher energy density and compact system design

• Lower operational noise

• Enhanced system stability in both hot and cold climates

Liquid cooling is not only effective in high-temperature scenarios but also performs exceptionally well in low-temperature outdoor installations, making it ideal for regions such as Eastern Europe.

Monitoring Data and System Verification

The customer provided comprehensive on-site data, including:

• Real-time energy management system (EMS) monitoring records

• Ambient temperature data

• Indoor inverter installation photos

• Outdoor liquid-cooled battery cabinet installation images

Operational data confirmed stable electrical output and safe thermal behavior, even under cold outdoor conditions.

Project Value for Cold-Climate Energy Storage

This Ukraine project highlights GSL ENERGY’s capabilities in:

• Outdoor energy storage deployment

• Low-temperature ESS design and validation

• Liquid-cooled energy storage engineering for C&I applications

It serves as a practical reference for customers planning energy storage projects in cold or seasonal climates.
