The wave of new energy is surging, and thermal management is crucial for power batteries as the core. Both high and low temperatures can seriously affect battery performance, lifespan, and even pose safety hazards. Therefore, an efficient liquid cooling and heating management system, especially its "heart" component - the liquid cooling radiator, has become the key to ensuring the "health" of batteries. The precise verification and optimization of the performance of liquid cooled radiators cannot be achieved without professional new energy storage liquid cooled fluid experimental equipment.

 

In order to standardize industry development and improve product quality, two heavyweight standards have recently been released:

 

T/CIAPS0016-2022 "Liquid cooled Heat Sink for Energy Storage Batteries"

QC/T 1206.2-2024 "Thermal Management System for Electric Vehicle Power Battery Part 2: Liquid Cooling System"

 

They provide authoritative technical specifications for liquid cooled radiator products and systems for energy storage and electric vehicles.
 

Focus on components

T/CIAPS0016-2022 "Liquid cooled Heat Sink for Energy Storage Batteries"

This standard focuses on a single core component of liquid cooled radiators and specifies its technical requirements, including appearance dimensions, sealing, burst/static pressure, environmental adaptability (salt spray, high and low temperature, and temperature cycling), internal durability (pressure cycling, internal corrosion), flow resistance, cleanliness and welding quality, water nozzle strength, etc. These rigorous tests, such as extreme pressure, environmental cycling, and precise flow resistance measurement, must be completed through professional liquid cooled fluid testing equipment to ensure the performance and reliability of the radiator unit.

 

Focus on the system

QC/T 1206.2-2024 "Thermal Management System for Electric Vehicle Power Battery Part 2: Liquid Cooling System"

This standard extends the perspective to the entire liquid cooling system of electric vehicle power batteries, covering all components such as liquid cooling plates, pipes, joints, etc., and comprehensively defines and tests the overall performance of the system, including system general requirements, system performance (flow resistance, safety performance such as sealing, flame retardancy), as well as technical requirements such as pressure resistance and burst pressure, vibration, welding strength, high and low temperature cycling, internal corrosion, pressure alternation, multiple insertion and removal and joint strength, negative pressure resistance, etc. To verify the complex performance of the entire liquid cooling system, such as dynamic vibration, high and low temperature cycling, pressure alternation, etc., extremely high requirements are placed on the testing equipment.

 

Behind the standards

New energy storage liquid cooled fluid experimental equipment: quality cornerstone

In this context, Lixun Testing Group actively responds to the forefront demands of the industry and has taken the lead in purchasing a set of five key high-end new energy storage liquid cooled fluid experimental equipment to comprehensively enhance its testing and verification capabilities, ensuring that the products meet or even exceed the requirements of the new standards:

 

Pulse test bench: used to simulate the pressure alternating working conditions that liquid cooling systems undergo during long-term operation, accurately evaluate their fatigue life, durability, and structural reliability under dynamic pressure, which corresponds to the strict requirements for "pressure alternating" in the standard.

 

Vacuum test bench/blasting test bench/airtight test bench comprehensive test bench: This comprehensive equipment can integrate the testing of the sealing (water/gas/helium detection), ultimate pressure bearing capacity (blasting/static pressure), and structural integrity in negative pressure environments of liquid cooled components and systems, ensuring that the product remains safe and reliable under extreme pressure and leakage risks.

 

Cold and hot cycle test bench: Simulate the working state of batteries at different environmental temperatures, verify the material stability, structural reliability, and performance consistency of liquid cooling systems in harsh environments through high and low temperature cycling and temperature alternation, and meet the environmental adaptability requirements for "high and low temperature cycling" in the standard.

 

Internal corrosion test bench: focuses on simulating the corrosion problems that may be caused by long-term circulation of coolant inside the system, evaluating the compatibility and corrosion resistance of materials, ensuring the reliability and service life of liquid cooling systems during long-term operation, and meeting the testing requirements for "internal corrosion" according to standards.

 

Flow resistance test bench: Accurately measuring the fluid resistance of liquid cooled components and the entire system, optimizing fluid channel design, ensuring efficient and uniform flow of coolant, is crucial for heat dissipation efficiency, and is the core verification method for the "flow resistance" performance indicator in the standard.


 

The strategic investment of Lixun Testing Group not only demonstrates its leading layout in the field of new energy testing and deep understanding of industry standards, but also provides comprehensive and high standard testing and verification services for liquid cooled radiators and their systems from components to systems, providing solid guarantees for liquid cooling technology innovation and product quality improvement in the new energy vehicle and energy storage industries, and accurately safeguarding the future development of battery safety and performance.
