Applications of Industrial Chillers in the New Energy Testing Industry

In the new energy testing industry, industrial chillers have evolved from mere auxiliary equipment into core infrastructure essential for ensuring data accuracy and accelerating R&D iteration. Their role extends far beyond simple cooling; they create a highly precise and dynamically controllable "thermal environment" for various tests. The following insights are provided by the team at Jianlong Hydraulic Technology to assist with your procurement decisions.

1. Precision Temperature Control: Safeguarding the "Lifeline" of Test Data

Many new energy tests are extremely sensitive to temperature; even minute fluctuations can lead to inaccurate results. For instance, during battery cell OCV (Open Circuit Voltage) testing, temperature variations can impact voltage by as much as 0.1 mV/°C. Consequently, the primary function of an industrial chiller is to provide a temperature-controlled environment characterized by high precision and stability.

1.1 Performance and Lifespan Testing: During tests such as battery charging/discharging and cycle life assessment, the equipment maintains the test subject's temperature within a tight range (e.g., 20°C ± 1°C). This eliminates temperature-related variables, ensuring the data accurately reflects the battery's intrinsic performance.

1.2 Environmental and Reliability Testing: To simulate real-world operating conditions—such as extreme cold or scorching heat—the industry frequently employs integrated high-low temperature units. These units offer temperature ranges from -40°C to +150°C and can execute rapid temperature transitions (e.g., 3–5°C/min) to verify the weather resistance of battery packs and electric motors.

2. From Components to Complete Vehicles: Spanning Every Stage of Testing

Industrial chillers are utilized across a wide spectrum of applications in the new energy testing sector, covering everything from individual battery cells to entire vehicle systems.

2.1 Battery Cells/Modules/Packs

• Key Applications: Charge/discharge aging, OCV testing, thermal shock, and thermal management performance evaluation.

• Typical Temperature Range/Precision: 0°C to 55°C; control precision of ±0.5°C or even ±0.1°C.

2.2 Electric Motors/Motor Controllers

• Key Applications: Motor performance testing, controller efficiency testing, and simulation of vehicle-level thermal management systems. • Example of controlled temperature range/precision: Dynamically adjusted based on testing requirements to simulate coolant temperatures ranging from -40°C to 85°C.

2.3 System-level/Bench Testing

• Key application scenarios: Integrated testing of vehicle thermal management systems; simulation of dynamic thermal characteristics (heating and cooling) of batteries.

• Example of controlled temperature range/precision: -40°C to +150°C, with support for complex programmed temperature profiling.

3. Moving Towards "Intelligence" and "High-Fidelity Simulation"

To meet the rigorous testing demands of the new energy industry, this type of equipment has adopted new technical characteristics:

3.1 High Precision and Wide Temperature Range: Equipment must operate across a broad range of -40°C to +150°C while maintaining temperature fluctuations within a precise margin of ±0.1°C to ±0.5°C.

3.2 Dynamic Simulation Capabilities: Modern equipment goes beyond merely maintaining a constant temperature. Using built-in PLC programming, it can simulate complex temperature profiles based on testing needs, accurately replicating the thermal conditions experienced during actual vehicle operation.

3.3 High Integration and Automation: Through communication protocols such as CAN and RS485, these temperature control systems easily interface with host testing units. This enables remote monitoring, automatic data logging (e.g., temperature, flow rate, and pressure curves), and even automatic adjustments to temperature control strategies based on test data.
