BES Cooling Systems
Reliable Climate Control Solutions for Battery Energy Storage Systems
Battery energy storage systems play a critical role in maintaining the balance between energy production and consumption and in ensuring the more efficient use of renewable energy sources.
To ensure that these systems operate safely, efficiently, and without interruption, the battery modules, power electronics components, and control equipment must be maintained at appropriate temperatures.
Klimexs BES cooling solutions provide stable temperature control for energy storage containers, battery enclosures, and outdoor energy infrastructure. and smart control features, they help protect system components and support operational continuity.
Why Is Temperature Control Important in Energy Storage Systems?
Battery cells generate heat during operation. A general temperature increase within the
sustem or temperature differences between
battery modules can cause one or several of the
following:
- A decline in battery performance,
- A decrease in charging and discharging efficiency,
- Faster aging of battery cells,
- An increased risk of malfunction in electronic equipment,
- Negative impact on system security
–
A properly designed climate control system does more than just cool the environment. It balances the temperature distribution inside the container or cabinet, helps ensure that equipment remains in optimal operating conditions, and supports the overall operational reliability of the energy storage system.
Designed for Harsh Outdoor Conditions
BES containers and energy storage cabinets are typically located outdoors. These systems may be exposed to varying environmental conditions throughout the year, such as high temperatures, low temperatures, dust, rain, humidity, wind, and solar radiation.
Klimexs outdoor climate control solutions have been developed to ensure that critical equipment operates reliably under these challenging conditions.
Due to the high protection rating of these
devices, The durable design of the enclosures, and the wide operating temperature range, Reliable climate control is ensured in energy storage systems.
Reliable performance under challenging conditions
Klimexs panel air conditioners are designed to
operate at high ambient temperatures and
come in a variety of configurable models With solutions tailored for ambient conditions that can reach +65 °C, they help ensure system continuity in hot climates and heavy-duty industrial applications.
Products are selected specifically for each application based on an assessment of the project’s location, container structure, heat load, and environmental conditions.
Specialized Thermal Management for BES Applications
The capacity, battery technology, container layout, and operating scenario vary for each energy storage project. Therefore, it is not sufficient to determine the cooling capacity based solely on container size.
Klimexs determines the appropriate HVAC solution for BES projects by evaluating the following criteria:
- The total heat load from the battery and inverter,
- Container or cabin dimensions,
- Interior equipment layout,
- Target operating temperature,
- Outdoor temperature range,
- Solar radiation,
- Risk of moisture and condensation,
- –
- Communication and remote monitoring requirements,
- Energy consumption and operating scenario.
With this approach, the cooling capacity required by the system is calculated accurately, thereby preventing the use of capacity that is either excessive or insufficient.
Smart, Secure, and Ready for Integration
In modern energy storage facilities, it is not enough for HVAC systems to operate independently. Cooling systems must be integrated with the
Battery Management System, the Energy
Management System, or the facility’s
automation infrastructure
Klimexs BES cooling solutions offer advanced communication and control features depending on the project and product configuration.
RS485 Modbus Communication
Thanks to RS485 Modbus support, air conditioner operating data can be transmitted to the central automation system. Temperature readings, operating status, and alarm information can be monitored remotely.
Ethernet connection
The Ethernet communication option enables the integration of HVAC systems into the network infrastructure and allows for more effective remote monitoring.
Alarms and Status Monitoring
Potential system malfunctions, high-temperature conditions, and operational alarms can be monitored through the central control infrastructure. This allows maintenance teams to respond more quickly to critical situations.
Synchronized aging feature
In redundant applications utilizing multiple air conditioners, the equal-aging function ensures the units operate on a rotational basis. Balancing operating times prevents any single unit from remaining under constant load and enables more effective management of system redundancy.
Synchronized Cooling for Seamless Operation
In large-capacity energy storage systems, a failure in the climate control infrastructure can cause the temperature inside the container to rise rapidly.
Therefore, for critical BES projects, redundant cooling solutions based on an N+1 or alternating operation logic may be preferred.
Thanks to Klimexs’ synchronized operation and communication features, multiple air conditioners can be operated in a coordinated manner. Units can be activated in rotation, their operating times can be balanced, and a backup air conditioner can be automatically integrated into the system as needed.
This structure:
- Supports operational continuity,
- It prevents the system from shutting down completely during maintenance,
- It balances the air conditioner’s operating times,
- It provides additional protection against unexpected malfunctions.
Energy-Efficient Cooling
In BES facilities, HVAC systems are a major component of auxiliary energy consumption.
In Klimexs solutions, high energy efficiency, proper capacity selection, and smart control are considered together.
By selecting the capacity that best suits the system’s needs:
- Unnecessary energy consumption is reduced,
- Excessive cycling is prevented,
- The indoor temperature is maintained at a more stable level,
- The service life of the equipment is extended,
- This helps reduce total operating costs.
