Unveiling the technological breakthrough of environmental testing equipment

The real reason behind the reduced winter range is that when your car experiences a 30% decrease in range at minus 20 ℃, it is essentially due to the battery undergoing "low-temperature shock": the electrolyte becomes viscous, slowing down ion movement, and the protective film reacts slowly, leading to a decrease in charging efficiency. These issues must be overcome through extreme environmental simulations during the development phase.

The temperature revolution of the three core technologies

Progressive temperature change training

Just like athletes need to adapt to high-altitude environments, our test chamber uses intelligent algorithms to allow the battery to undergo 150 temperature changes from the equator to the poles within 72 hours. The non-linear variation of 3 ℃ per minute accurately reproduces the temperature shock in real road conditions,

Humidity coupling challenge

The unique centrifugal fan system can maintain ± 2.5% RH fluctuation accuracy in 85% high humidity environment, and the battery sealing performance can be fully verified whether it is humid during rainy season or dry in desert areas.

Micro data capture

A temperature sensor with a precision of 0.2 ℃ is like installing a health monitor on a battery. Combined with the voltage/internal resistance synchronous analysis system, it is possible to locate the specific performance degradation point of the battery cell, which is

the dawn moment of a technical team

Last winter, a certain R&D team discovered a key breakthrough in the STM-64C test chamber of Xingtuo:

*Lock in the critical point of electrolyte activity decrease through 50 cycles of -40 ° C → 25 ° C testing

*After adjusting the formula, the charging efficiency in the -30 ℃ C environment increased by 19%

*The final mass-produced battery has a winter endurance retention rate of over 85%

The quality defense line forged in twenty years

Each Xingtuo test box embodies:

√ French Taikang two-stage compressor refrigeration technology (-70 ℃ C deep low temperature simulation)

√ Aviation grade silicone sealing structure (10-year air tightness guarantee)

√120 sets of programmable test modes (meeting global certification standards)
