01 Xi’an Gravity: The Western Highland of New Energy Investment

In the ancient capital of Xi’an, early November brings sudden cold weather, but the new energy market is booming, with continuous growth in production of new energy vehicles, lithium batteries, and charging piles. On this fertile ground for investment, a leading domestic mobile energy storage company has officially set foot in the market, with its high-standard product testing laboratory recently completed and put into operation. Notably, the company’s first batch of more than 20 environmental reliability test chambers all used the SCICOOLING brand. This batch of equipment is comprehensive, including temperature test chambers, temperature and humidity test chambers, walk-in test chambers, explosion-proof test chambers, and quick-temperature transformers.

02 Professional Environmental Testing: Safeguarding energy storage safety

Energy storage products include batteries, cells, and complete machines, with the core of which lies in the battery, whose performance and safety heavily depend on its performance in various extreme environments. The test chamber provided by SCICOOLING is precisely the “expert” simulating these extreme conditions. The temperature test chamber can simulate dramatic temperature changes from -40°C to 150°C, testing battery charge/discharge performance, capacity retention, and material durability. The cooling rate of the fast thermometer reaches ≥15°C/min (under load).

The dedicated explosion-proof box provides a “double safe” for battery safety testing, adding explosion-proof pressure relief windows, explosion-proof door locks, hinges, and explosion-proof windows. The 6m³ walk-in test chamber weighs up to 0.5T + 2KW of heat. Together, these devices form a comprehensive and rigorous testing matrix, ensuring that every energy storage product has been rigorously tested in simulated extreme environments before being delivered to users worldwide.

03 Technology wins trust

Among the many environmental test equipment brands, why is this leading company so fond of SCICOOLING? Technical foundation is one of the key factors. SCICOOLING inherits its expertise from the Institute of Physical and Chemical Technology, Chinese Academy of Sciences, and boasts a strong technical foundation. More than 35% of the company’s technical R&D talent accounts for the company. We have participated in drafting national standard documents such as the temperature test chamber and temperature and humidity test chamber. It is a national postdoctoral workstation unit and holds 14 national invention patents, making it one of the few enterprises in the industry with sustained R&D capabilities.

A deep understanding of testing requirements in the new energy industry is another major advantage of SCICOOLING. Many test chamber SCICOOLING companies tailor solutions based on customer needs, rather than standardized general-purpose equipment, fully meeting customers’ professional requirements in specific testing scenarios such as battery overcharge and discharge, and high/low temperature cycling. Particularly noteworthy is SCICOOLING’s energy-saving technology. Based on actual measurements and comparisons, the SCICOOLING 1m³ high and low temperature and humidity test chamber saves 24%~84% of electricity consumption during temperature and humidity constant, temperature adjustment and temperature transition, and temperature cycling. The reason is that traditional high and low temperature chambers mostly use “hot and cold balance” control technology, while SCICOOLING employs its independently developed “intelligent PID control technology.” This control technology can be scientifically calculated based on actual load conditions to ensure the test chamber can provide precise heating or cooling output, so that the system “cools without heating, heats without cooling,” thereby saving electricity and energy.

04 The Collective Choice of Leading New Energy Companies

Looking at the domestic new energy industry chain, SCICOOLING’s equipment has been widely used by many well-known enterprises. From the established powerhouse Fengfan Battery, to new energy vehicles like BYD and XPeng, to leading lithium-ion battery module manufacturer Sunwoda, power lithium battery leader Xingheng Energy, and even Fortune Global 500 companies like CNNC Group and China State Shipbuilding Corporation, SCICOOLING equipment can be seen everywhere.
