Today, as the automobile industry accelerates its transformation to electrification and intelligence, whether it is a new energy vehicle galloping in the cold snowfield or a traditional fuel vehicle shuttling through the tropical heat, they must face the severe test of the world's diverse climate and complex road conditions. As the core equipment for simulating extreme environments, the environmental test chamber has become an indispensable "quality guard" in the whole process of R&D, production and quality inspection of automobiles and parts. Danble Instruments has been deeply involved in the field of environmental test equipment for many years, providing key support for the reliability upgrade of new energy and traditional automobile industries with high-precision and high-stability test solutions.

integrated product, the stability of the overall performance of the car in extreme environments is directly related to driving safety. Danble instrument environmental test chamber and large laboratory can achieve a wide temperature range coverage of -80°C to 180°C and precise humidity control of 10%~95% RH, perfectly reproducing various extreme climate scenarios around the world, and providing a reliable platform for vehicle performance verification.

In the field of traditional fuel vehicles, the high and low temperature test of the whole vehicle focuses on the engine system and driving safety. By simulating the extremely cold environment of 40°C, the cold start performance of the engine and the low-temperature reliability of the lubrication system can be verified, and the starting failure caused by oil solidification can be avoided. In a high temperature of 50°C and 80% RH high humidity, it can accurately detect the engine heat dissipation efficiency, air conditioning cooling effect, and fuel system tightness to prevent power attenuation or fuel leakage risks at high temperatures. At the same time, the response accuracy of safety systems such as ABS and ESP under the condition of sudden temperature changes can also be fully verified by rapid temperature change tests.

For new energy vehicles, vehicle testing focuses more on battery system and electronic control performance. Danble explosion-proof battery test chambers, large walk-in test chambersIt can accommodate a complete battery pack and the whole vehicle body, and evaluates the charging and discharging efficiency, battery life attenuation law and thermal management system adjustment ability of the power battery by simulating the temperature and humidity cycles of different climate zones. The low-temperature starting performance and capacity retention rate of the battery pack can be tested at -30°C. In a high temperature and high humidity environment, the effectiveness of the battery thermal runaway protection system can be verified, and a solid line of defense can be built for the safe driving of new energy vehicles. In addition, extreme environmental performance of comfort configurations such as on-board air conditioning and heated seats can also be optimized through accurate environmental simulation.

The reliability of automobiles comes from the quality of each component. Danble Instruments provides customized environmental test solutions for the characteristics of different components, from material weather resistance to system stability, covering the core component systems of new energy and traditional vehicles.

power system as the "heart" of the automobile, and its components need to withstand continuous temperature stress and mechanical load. In traditional fuel vehicle engines, key components such as pistons and valves need to pass high-temperature durability tests, and evaluate the thermal stability and fatigue resistance of materials in an environment that simulates engine operating temperature, so as to ensure that there is no deformation and no risk of fracture under long-term high temperature and pressure. while precision components such as fuel injectors and turbochargers can be tested through temperature and humidity cycling tests to verify their sealing performance and response accuracy in alternating hot and cold environments.

The motor and electronic control system of new energy vehicles are more sensitive to the environment. With a temperature fluctuation control accuracy of ±0.1°C, the Danble high-precision test chamber can simulate the temperature gradient change during motor operation, and test the insulation performance of the winding and the thermal deformation characteristics of the rotor material. The electronic control unit (ECU) needs to undergo a temperature shock test of -40°C~125°C (the number of cycles ≥ 50 times) to ensure the stability of chip computing and signal transmission under extreme temperature differences, and avoid power interruption caused by electronic control failure.

Power batteries are the core competitiveness of new energy vehicles, and their environmental adaptability directly determines the vehicle range and safety. Danble Instruments has created special test solutions for battery packs, battery cells and BMS systems, and verified the whole dimension from materials to systems.

At the battery cell level, the high-temperature aging test can accelerate the degradation process of electrolyte performance and predict the cycle life of the battery cell in advance. The low-temperature charge and discharge test can accurately capture the capacity change curve at different temperatures and provide data support for battery capacity calibration. For the battery pack, the temperature and humidity + vibration composite test is used to simulate the bumps and environmental changes during vehicle driving, test the structural strength and sealing performance of the battery pack, and prevent the risk of short circuit caused by water vapor infiltration.The battery management system (BMS) needs to operate continuously in a temperature cycle of -30°C~55°C and a high humidity environment of 95% RH to verify its endurance measurement accuracy and timeliness of thermal runaway warning, which is the core testing capability of the Danble test chamber.

With the intelligent upgrading of automobiles, the proportion of electronic and electrical components continues to increase, and its environmental stability has become the key to vehicle reliability. Danble Instruments provides multi-dimensional environmental testing solutions for the characteristics of automotive electronic components, fully meeting the requirements of industry standards such as ISO 16750 and GB/T 2423.

As a "sensory organ", automotive sensors need to respond to various environmental challenges. The tire pressure monitoring sensor can verify its signal stability in scenarios such as entering and exiting tunnels, air conditioning start and stop, etc., and avoid poor contact caused by thermal expansion and contraction. Millimeter-wave radar and vehicle cameras need to undergo condensate protection tests to detect whether the lens is fogged up and whether the circuit is damp under the condition of sudden drop in high humidity environment to ensure the reliable operation of the assisted driving system.

Terminal equipment such as vehicle multimedia and air conditioning control can comprehensively investigate potential problems such as oxidation of circuit board solder joints and shell seal failure through 70°C high-temperature operation test and 60°C/95% RH humid-heat storage test, ensuring smooth operation and display clarity in extreme environments. For special components such as charging interfaces and high-voltage wiring harnesses of new energy vehicles, customized temperature and humidity tests can also be used to verify their insulation performance and conductive stability to prevent the risk of electric shock.

the environmental adaptability of body structure and interior materials, which directly affects the service life and driving experience of the vehicle. Danble instruments achieve comprehensive verification from structural strength to environmental performance through diverse environmental simulations.

metal parts of the body can accelerate the simulation of corrosive environments such as rain and haze through the salt spray + damp-heat composite test, evaluate the protective effect of the anti-rust coating, and extend the service life of the body. Rubber seals, tire rubber strips and other elastic parts need to be tested at a low temperature of -40°C to verify their elastic retention ability and prevent seal failure or driving noise caused by low temperature shrinkage.

The testing of interior materials pays more attention to safety and comfort. The aging deformation and odor release of plastic parts and leather seats in high temperature environments can be accurately detected by high-temperature aging tests; Materials such as soundproof cotton and floor mats need to pass constant humidity and heat tests to evaluate the anti-mildew performance to avoid mold growth and affect the air quality in the car. These test data provide a quantitative basis for car companies to optimize material selection and improve the driving experience of the whole vehicle.
