In the rapidly evolving landscape of Electric Vehicles (EV) and Energy Storage Systems (ESS), the role of a Custom Thermal Chamber has shifted from a luxury to a critical regulatory necessity. As energy densities in lithium-ion cells increase, so does the risk of thermal runaway. Modern battery testing requires more than just "hot and cold" cycles; it demands precise environmental control, integrated safety features, and high-speed data acquisition.
Dongguan Huanyi Instruments Technology, a leader since 2007, understands that every battery pack—from a small smartphone pouch cell to a massive 100kWh EV pack—has a unique thermal profile. Our systems are engineered to simulate extreme conditions, ensuring that your products meet UN38.3, UL 2580, IEC 62619, and other global safety standards.
Our chambers are equipped with pressure release vents, smoke sensors, and CO2 suppression systems to handle battery failures safely during stress tests.
Advanced PID control algorithms ensure temperature stability of ±0.5°C, even with active heat loads from the battery charging cycles.
Seamlessly integrate with BMS communication protocols and battery cyclers for synchronized environmental and electrical testing.
China has become the global hub for battery manufacturing (CATL, BYD, Gotion), which has naturally birthed a world-class testing instrument ecosystem. Dongguan Huanyi Instruments offers:
Dongguan Huanyi Instruments Technology Co., Ltd. was established on March 20, 2007, covering an area of 6,022 square meters. It is a high-tech enterprise integrating R&D, production, sales and after-sales service. It participated in the drafting of national standards and industry standards for environmental simulation test equipment.
Our philosophy is "customer-centric, quality-guaranteed, honesty-based, and innovation-oriented". Through unremitting efforts, Huanyi has cultivated a high-quality team with rich production, R&D and management experience.
