With the booming development of the new energy vehicle market in recent years and significant year-on-year sales growth, market competition has become increasingly fierce. In this context, overall vehicle performance and reliability have become crucial factors for brands to stand out. Danble Instruments' walk-in vehicle environmental chamber is a core piece of equipment that safeguards the research and development and quality verification of new energy vehicles.

The severe challenges facing new energy vehicle testing

New energy vehicles, especially pure electric and intelligent connected vehicles, have core components such as battery systems, electric drive and control systems, and intelligent cockpits that require environmental adaptability far exceeding that of traditional fuel vehicles:

• Battery performance: In extremely cold environments, battery range is reduced and charging speed decreases, while in high temperatures, there is a risk of thermal runaway.

• Electronic system reliability: Complex sensors, controllers, and entertainment systems need to operate reliably across a wide temperature range and in high-humidity environments.

• Vehicle adaptability: Ensure that the vehicle remains in good condition in different climates and geographical environments.

The core value of Danble's walk-in vehicle environmental test chamber.

Danble Instruments' walk-in vehicle environmental chambers provide comprehensive testing solutions for new energy vehicles by simulating various environmental conditions such as temperature, humidity, and light.  Its main applications include:

1. High and low temperature performance verification of the battery system.

The battery high and low-temperature charging and discharging tests are conducted on the complete new energy vehicle to evaluate the performance, thermal management efficiency, and safety of the battery pack under extreme temperatures, providing crucial data for BMS strategy optimization.

2. Vehicle durability and environmental adaptability testing

• Whole vehicle four-door and two-hood high and low temperature environment testing: This system is used for performance and durability testing of complete vehicles or vehicle bodies (with four doors and two hoods) for passenger cars, incorporating environmental temperature and humidity simulation control.

• High-temperature and high-humidity aging test with sunlight simulation: This test verifies the aging resistance of the entire vehicle and its interior materials under combined conditions of high temperature, high humidity, and strong sunlight.

• Component system assembly high/low temperature and durability testing: The reliability of each component assembly is tested under high and low temperature life cycle conditions.

3. Precise evaluation of thermal management systems

By simulating various temperature and humidity environments ranging from extreme cold to extreme heat, the system tests the cooling performance of a car's air conditioning system in high-temperature, high-humidity conditions, as well as its starting performance and battery life in low-temperature, low-humidity environments. This helps automakers optimize the design and control strategies of the vehicle's thermal management system.

4. Environmental reliability testing of materials and interior components.

This test evaluates the changes in physical properties of automotive interior materials, body coatings, rubber seals, and other materials under different temperature and humidity conditions, preventing problems such as deformation, cracking, and aging caused by temperature and humidity fluctuations.

Technical advantages of Danble's walk-in vehicle environmental test chamber.

Thanks to years of technological accumulation and a deep understanding of the testing requirements for new energy vehicles, Danble Instruments' walk-in vehicle environmental chambers offer significant advantages:

• Precise environmental simulation: It provides a wide range of temperature and humidity control, ensuring a uniform and stable environment inside the chamber to meet various testing standards.

• Flexible and customizable design: Based on customer testing requirements, we can customize test chambers of different sizes and configurations to support testing of complete vehicles, battery packs, or large components.

• Comprehensive integrated solutions: Optional features include a solar radiation simulation system, low-pressure simulation (for simulating high-altitude and high-altitude climate conditions for storage, operation, and transportation reliability testing), and a fresh air system, enabling comprehensive multi-factor environmental simulation.

• Intelligent control system: By employing advanced control algorithms and data processing systems, the system achieves precise control of the experimental process and ensures the integrity of data recording.
