As new energy technologies continue to evolve at an unprecedented pace, the role of environmental simulation systems in test chambers is becoming increasingly complex and precise. In particular, temperature control systems have transformed from auxiliary components into performance-critical cores—especially in battery testing and energy storage system thermal management. Testing conditions such as thermal runaway validation, fast-charging stability, and extreme temperature cycling now impose significantly higher demands on chiller performance.
In response to these rising challenges, the DHT® Chiller, a recently launched intelligent thermal control solution from DHT®, offers a comprehensive upgrade in temperature accuracy, energy efficiency, and system connectivity. Designed with the multifaceted needs of test chamber users in mind, both in day-to-day operation and long-term reliability, this article explores why the DHT® Chiller is the next-generation thermal control system laboratories can truly rely on.
From “Temperature Device” to “Testing Engine”: The All-in-One Positioning of the DHT® Chiller
Conventional chillers have traditionally served as peripheral cooling units. However, with increasing complexity in test systems, the role of chillers has fundamentally evolved. They are no longer just cooling devices, but integrated nodes with capabilities in coordination, control, data recording, and system feedback.
The DHT® Chiller is a high-performance thermal management solution designed precisely in line with this shift. It delivers exceptional stability and scalability across demanding applications, including EV power battery testing, energy storage battery packs, and high-efficiency semiconductors—ensuring a highly precise, stable, and intelligent thermal environment throughout the entire testing process.
-40°C to 100°C: Accurate Temperature Control for Extreme Conditions
Every simulation test in the lab demands unwavering thermal stability. The DHT® Chiller covers an extended temperature range from -40°C to 100°C, with control accuracy of ±0.5°C, providing a reliable thermal foundation for research and validation work.
This performance is especially critical when testing advanced materials such as high-nickel ternary lithium batteries and solid-state batteries under extreme cold-start and thermal runaway scenarios. The DHT® Chiller ensures consistent and repeatable testing, significantly enhancing the scientific validity of reliability assessments.
Its capabilities stand out in extreme conditions where traditional chillers fall short, including:
-
BMS fuse-response tests under fast-charging conditions
-
Battery cell recovery capacity evaluation at subzero temperatures
-
Boundary determination of thermal propagation in safety tests
For test chamber manufacturers and laboratories alike, the DHT® Chiller is no longer a supporting component—it becomes a crucial variable controller in the thermal simulation ecosystem.
Intelligent CHT Thermal Regulation: Energy Efficient and Precision-Driven
For most test system users, the hidden cost of chillers—energy consumption—is a significant concern. Traditional systems often operate at full cooling output even under low load, requiring additional heating to balance, leading to energy waste through counteracting heating and cooling.
The DHT® Chiller features DHT®’s proprietary CHT (Cooling-Heating Transfer) intelligent thermal regulation technology, which dynamically adjusts the ratio of cooling and heating output based on real-time test conditions. This not only ensures precise thermal balance but also greatly improves energy efficiency.
Field data from typical battery testing scenarios show that the DHT® Chiller can reduce energy consumption by up to 30% compared to conventional systems. This advancement helps users significantly cut operational costs while aligning with green manufacturing and sustainability goals across the industry.
System-Level Connectivity: Building a Central Data Hub for Testing
With Industry 4.0 accelerating across laboratories and manufacturing lines, connectivity is no longer optional. The DHT® Chiller delivers system-level compatibility and information integration far beyond traditional solutions:
-
Native support for CAN and Modbus protocols allows seamless integration with control platforms and BMS systems
-
Equipped with Ethernet and USB interfaces for local data export and remote transmission
-
Compatible with cloud platforms and IIoT systems for real-time condition monitoring and remote diagnostics
-
Supports pre-warning linkage mechanisms, enabling automatic alarms or protective actions in response to abnormal temperature, flow, or pressure parameters
These features elevate the DHT® Chiller from a cooling device to a smart thermal control hub, driving the digital transformation of laboratory assets and enhancing data transparency across the entire testing chain.
Safety-Driven Design: The First Line of Defense for Fast-Charging Stress Tests
Fast-charging technologies have greatly improved user convenience but have also increased the risk of thermal runaway in batteries. The DHT® Chiller addresses this with the ability to simulate sustained high-temperature environments (up to 100°C) and actively engage BMS systems to trigger fuse protection mechanisms—providing rigorous and realistic conditions for boundary safety testing.
It demonstrates strong adaptability in safety-critical testing scenarios such as:
-
Validation of thermal propagation pathways
-
Thermal dissipation capacity testing under abnormal charging environments
-
Module-level fuse response verification
With these capabilities, the DHT® Chiller pushes battery safety testing into a new depth—one that is systematic, data-backed, and scenario-specific.
Reliability Meets Maintainability: Designed for Long-Term Operation
Long-term operational stability and ease of maintenance are key concerns for users. From its early design phase, the DHT® Chiller has integrated health management features to ensure dependable long-term performance:
-
Real-time status feedback with external components (e.g., battery valves) for adaptive operation and lifespan extension
-
Automated operation logs for streamlined diagnostics and traceability
-
Supports remote preventive maintenance strategies to minimize unplanned downtime and reduce labor intensity
This forward-thinking design philosophy ensures the DHT® Chiller delivers significant “invisible value” over its entire lifecycle—aligning with the needs of high-usage laboratory environments.
Conclusion: A Thermal Control Solution Purpose-Built for Battery Management
The launch of the DHT® Chiller represents more than just an upgrade of conventional refrigeration products—it is a redefinition of the thermal platform tailored to the realities of test chamber applications. Through:
-
Wide-range and accurate temperature control
