GB 38031-2025 new national standard implementation: Sanwood Technology Battery Environment Test Chambers helps new energy industry upgrade

In recent years, China's new energy vehicle market continues to develop at a high speed, however, battery safety accidents still occur from time to time, in this context, the National Standardization Administration officially released GB38031-2025 “Power Storage Battery Safety Requirements for Electric Vehicles”. As a professional enterprise in the field of environmental simulation test equipment, the Battery Environment Test Chambers and safety test solutions independently developed by Sanwood Technology is helping enterprises upstream and downstream of the new energy industry chain to quickly meet the requirements of the new national standard, and jointly promote the industry's safety upgrade.

First, the standard upgrade 

Compared with the 2020 version, GB38031-2025 has been significantly upgraded in many dimensions, the standard introduces a number of unprecedented safety provisions:

- Battery systems must not catch fire or explode for at least two hours after a thermal runaway event; - Smoke is prohibited from entering the passenger compartment during this period; 

- Batteries must withstand 300 consecutive fast-charge cycles (from 20%  to 80% charge), with each charge lasting no more than 15 minutes; 

- In addition to external heating and battery puncture tests, a new test simulating thermal runaway triggered by an internal heat source has been added. 

These requirements far exceed the current EU and U.S. regulations, the latter two have not put forward such high performance standards. 

Second, Sanwood Technology’s Battery Environment Test Chambers to helps drive development

In the face of GB38031-2025 high standard requirements, battery manufacturers, car companies and third-party testing organisations urgently need to upgrade testing capabilities. Sanwood Technology has been ploughing into the field of environmental simulation testing for many years, the introduction of the Battery Environment Test Chambers and a full set of safety testing solutions, can help industry customers to cope with the new national standard.

Third, the product and equipment introduction 

Battery Environment Test Chambers: 

Temperature range: -70 ℃ ~ +180 ℃ 

Temperature uniformity: ≤ 1.5 ℃ (-40 ℃ ~ +100 ℃) 

                                        ≤ 2 ℃ (+100.1 ℃ ~ +180 ℃ or -40 ℃ ~ -70 ℃) 

Temperature fluctuation: ≤ ± 0.5 ℃ 

Temperature decline rate: +180 ℃ ~ -70 ℃ (about 100 minutes within 1 ~ 3 ℃ / min) 

Temperature Rising speed: -70℃~+180℃ (within about 60 minutes 3~5℃/min) 

The Battery Environment Test Chambers independently developed by Sanwood Technology is made of high-temperature-resistant and corrosion-resistant special materials, with the ability to accurately control a wide temperature range of -70℃~+180℃, which can satisfy the needs of various types of power batteries for safety testing in extreme environments. At the same time, it is equipped with high-strength explosion-proof observation window and intelligent monitoring system, which can not only ensure visual observation of the experimental process, but also provide reliable safety protection for the operators, and it is the ideal test equipment to help enterprises to cope with the requirements of the new national standard GB38031-2025.

The implementation of GB38031-2025 “Safety Requirements for Power Storage Batteries for Electric Vehicles” will be a historic step in the safety of China's new energy industry. For battery companies, meeting the new standard is not only a compliance requirement, but also a core opportunity to enhance product competitiveness and win the market.

As a supplier of environmental simulation test equipment, Sanwood Technology is committed to providing high-precision and high-reliability test solutions for the new energy industry, helping enterprises to meet the challenges of the new national standard, and jointly promoting the safety upgrade of the global new energy industry!
