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

In Ukraine, where winter temperatures often fall below freezing, GSL ENERGY successfully deployed a 160kW / 418kWh liquid-cooled energy storage system (ESS) designed for reliable 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 conditions. Despite sub-zero ambient temperatures, the system has continued to operate safely, efficiently, and stably, demonstrating the robustness of GSL ENERGY's liquid-cooled energy storage technology.

This project provides a strong 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

Performance in Low-Temperature Conditions

During operation, local ambient temperatures reached below 0°C, which can pose challenges for conventional air-cooled or poorly managed battery systems.

However, the GSL ENERGY liquid-cooled ESS demonstrated:

    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 ensures that when external temperatures drop, the internal battery heating mechanism is automatically activated, keeping battery cells within an optimal operating temperature range.

This capability significantly enhances system reliability, battery safety, and lifecycle stability in cold climates.

Advantages of Liquid-Cooled Energy Storage in Cold Regions

Compared with traditional air-cooled systems, GSL ENERGY’s liquid-cooled ESS offers clear advantages in environments with large temperature variations:

Precise thermal control for each battery module

Improved temperature consistency, reducing cell imbalance

Higher energy density and compact system design

Lower operational noise

Enhanced system stability for both hot and cold climates

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

Monitoring & Visual Evidence

The customer provided comprehensive on-site data, including:

Real-time energy management system (EMS) monitoring data

Ambient temperature display records

Indoor inverter installation photos

Outdoor liquid-cooled battery cabinet installation images

All operational data confirms that the system maintains stable electrical output and safe thermal behavior, even when exposed to cold outdoor conditions.

Project Value & Reference Significance

This Ukraine project highlights GSL ENERGY's capabilities in:

Outdoor energy storage deployment

Low-temperature system design and validation

Liquid-cooled ESS engineering for C&I applications

It serves as a practical reference case for customers planning energy storage projects in regions with seasonal low temperatures.
