In the rapidly evolving landscape of New Energy Vehicles (NEV) and high-density energy storage, the demand for rigorous Environmental Battery Test Chambers has reached an all-time high. As a premier manufacturer established in 2007, Dongguan Huanyi Instruments Technology Co., Ltd. stands at the intersection of engineering expertise and innovative research.
Our role goes beyond simple manufacturing; we are architects of safety. By providing critical "Information Gain" through our involvement in drafting national standards (GB5364, GBT50325), we ensure that every test chamber we deliver is a testament to reliability and technical authority.

Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007. It is a high-tech enterprise integrating R&D, production, sales and after-sales service. Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented".
Since 2018, it has been continuously rated as a high-tech enterprise for six consecutive years. We have expanded our footprint with offices in Jiangsu, Xi'an, Chongqing, Shanghai, and Beijing, ensuring nationwide and global support.
Our 2016 establishment of a dedicated Digital Sheet Metal Center allows for precision laser cutting and automated folding, reducing waste and ensuring structural integrity for high-pressure explosion-proof chambers.
We use advanced ERP systems to monitor every stage of production—from raw material procurement of international brand components to final installation—guaranteeing timely delivery for large-volume OEM orders.
In 2022, we established "Guangdong Huance Testing Technology Co., Ltd," a dedicated laboratory to validate our own equipment performance, providing customers with empirical data support.
The global battery industry is transitioning from traditional liquid-state Lithium-ion batteries to solid-state and hydrogen fuel cell technologies. This shift necessitates Custom Environmental Test Chambers that can handle higher energy densities and unique safety risks. Global enterprises now require testing equipment that satisfies not just basic temperature controls, but complex Multi-Stress Environments.
Compliance & Localization: For enterprises expanding into Europe and North America, compliance with CE, UL, and ATEX standards is non-negotiable. Our chambers are designed with localized safety features, such as fire suppression systems, gas sensors, and pressure relief vents, specifically tailored to the safety protocols of regional regulatory bodies.
Sustainability in Testing: We are seeing a trend toward "Green Labs." Huanyi is pioneering the use of low-GWP (Global Warming Potential) refrigerants and energy-efficient compressors, helping our clients achieve their carbon neutrality goals while maintaining precision ±0.5°C control.
High Quality Control from every aspect of raw material, production, installation, and commission. Main components are from internationally renowned brands.
With more than 20 years of experience, our R&D personnel can meet large-volume production orders at any time with ERP system monitoring.
Laser cutting panels, automated production, and wood cutting automation help us reduce waste and improve precision.
ISO 9001 factory manufacturing. Participation in drafting national standards for environmental simulation equipment.
1. What safety features are mandatory for high-energy battery testing?
For battery thermal abuse or explosion tests, we integrate electronic locks, pressure relief ports (blast vents), smoke/gas detectors (CO, H2), and automated CO2 or Nitrogen fire suppression systems to prevent catastrophic lab failure.
2. Can your chambers simulate "Drive Cycle" battery profiles?
Yes. Our programmable controllers can sync with battery cyclers via RS485 or LAN to simulate real-world driving conditions, including rapid temperature changes coupled with high-current charging/discharging.
3. How do you ensure the uniformity of temperature in large walk-in chambers?
We utilize a multi-blade centrifugal fan system with adjustable air louvers. By using CFD (Computational Fluid Dynamics) modeling, we ensure temperature uniformity within ±2.0°C even in chambers exceeding 50 cubic meters.
4. What is the advantage of a "Liquid-to-Liquid" Thermal Shock Chamber?
Liquid thermal shock provides a significantly higher heat transfer coefficient than air, allowing for the most extreme stress tests on battery casing materials and seals, simulating rapid immersion scenarios.
5. Do you provide onsite calibration and maintenance globally?
While our HQ is in China, we offer remote diagnostic support via cloud-connected controllers and partner with local service providers in Southeast Asia, Europe, and the Middle East for onsite calibration.
The main components of all the company's products are made of internationally renowned brand components to ensure performance. We have fully realized product upgrades and launched new domestically advanced test instruments widely praised abroad.
