Efficient Thermal Management for Battery Energy Storage Systems
As battery energy storage systems (BESS) continue to expand across India, effective thermal management has become increasingly important for system safety, performance, and long-term reliability.
For one of our recent energy storage projects in India, Cooltechx supplied a 20kW liquid cooling HVAC system together with a customized coolant piping solution, providing stable thermal management for the battery system.
The project demonstrates Cooltec’s ability to provide not only the liquid cooling unit, but also the complete cooling solution including HVAC, piping design, and system integration.
Project Requirements
The customer required a liquid cooling solution for a battery energy storage system operating under demanding environmental conditions.
The main requirements included:
- Cooling capacity: 20kW
- Liquid cooling HVAC system
- Customized coolant piping
- Stable battery temperature control
- Reliable operation under high ambient temperatures
- Efficient heat transfer between the cooling system and battery system
- Easy integration with the BESS thermal management system
- Long-term and continuous operation
India’s climate can present significant challenges for outdoor energy storage systems, particularly during periods of high ambient temperature. Therefore, the cooling system needed to provide stable performance under demanding operating conditions.
20kW Liquid Cooling HVAC + Piping System
Based on the customer’s battery system and thermal requirements, Cooltec designed and supplied a 20kW liquid cooling HVAC solution.
Instead of simply supplying a standalone chiller, Cooltec worked around the complete thermal management system, including the cooling unit and coolant circulation piping.
The system consists of:
20kW Liquid Cooling HVAC
The liquid cooling unit removes heat from the circulating coolant and continuously provides cooling for the battery thermal management system.
Customized Coolant Piping
The piping system was designed according to the battery system layout, cooling requirements, flow requirements, and installation conditions.
Cooling Distribution
The coolant is circulated through the battery cooling system to transfer heat away from the battery packs and maintain a more stable operating temperature.
System Integration
The HVAC and piping system can be integrated with the customer’s BMS/EMS and overall BESS control strategy according to project requirements.
Why Liquid Cooling for BESS?
As battery energy density increases, thermal management becomes more challenging.
Liquid cooling provides several advantages for high-energy-density battery systems:
- Higher heat transfer efficiency
- More uniform battery temperature control
- Suitable for high-density battery systems
- Compact thermal management design
- Better control of battery operating temperature
- Suitable for large-scale containerized BESS
For projects with high battery capacity or high heat loads, liquid cooling can provide a practical solution for maintaining stable thermal conditions.
Engineering Beyond the Cooling Unit
One of the key advantages of the Cooltec solution is that we do not focus only on the HVAC equipment.
For each BESS project, our engineering team can evaluate:
- Battery heat generation
- Required cooling capacity
- Coolant flow rate
- Supply and return temperatures
- Piping layout
- Pipe diameter and pressure drop
- Cold plate requirements
- Ambient temperature
- Container or cabinet dimensions
- BMS control requirements
This allows us to develop a more complete thermal management solution rather than treating the cooling unit as an independent component.
Successful Application in India
The successful delivery of the 20kW liquid cooling HVAC and customized piping system provides the customer with a complete thermal management solution for its energy storage application.
The system is designed to help maintain stable battery temperatures, improve thermal consistency, and support reliable long-term BESS operation.
This project also strengthens Cooltec’s experience in providing liquid cooling solutions for the rapidly developing Indian energy storage market.
