C-EVFI WORKSHOP
May 13, 2025
China Electric Vehicle Fire Safety Index – Workshop under the guidance of Dr. Chen Bin from CMVR
C-EVFI adopts the pin-prick triggered thermal runaway evaluation method in order to test the potential risk of battery ignition in electric vehicle fire accidents. The core content of the test is:
Firstly, simulating a real collision scenario: through the needle puncture test with a steel needle piercing the battery monomer, replicating a guardrail, debris and other foreign objects piercing the battery pack, determining whether it will lead to an internal short- circuit and triggering thermal runaway, and evaluating the anti-intrusion capability of the battery.
Secondly, a more stringent pin-prick test: GB 38031- 2020 ‘Safety Requirements for Power Storage Batteries for Electric Vehicles’ requires that the battery system does not catch fire within 5 minutes after thermal runaway, while C-EVFI adopts a more stringent pin-prick test, requiring that the battery does not catch fire within 2 hours, which gives more operating time to the driver and the rescuer, and boosts the development of the vehicle by vehicle enterprises using higher safety standards.

Dr. Chen BinResearcherCMVR - China Merchants Testing Vehicle Technology Research Institute Co., Ltd. VitaBin Chen, PhD. D. is dedicated to the research of fire safety technology for new energy vehicles, achieving several industry firsts and forming systematic research results including equipment, standards and basic research. He developed the industry's first "integrated test platform for multi-source data fusion of new energy vehicle fires", formulated the industry's first "Electric Vehicle Fire Safety Test Methods" standard, developed the industry's first "China Electric Vehicle Fire Safety Index", and set up the industry's leading fire prevention, control and investigation system for new energy vehicles. He established the industry-leading new energy vehicle fire prevention system of "prevention, control and investigation". Dr. Bin presided over/participated in more than 10 scientific research projects at national, provincial and ministerial levels, applied for more than 10 patents and software copyrights, and published more than 20 SCI/EI papers. |
Additionally, the mechanical lock function is tested. In the event of a fire or collision, the ability to unlock the doors quickly is the key to escape. Although vehicles are designed with an ‘emergency mechanical handle’, it may not work in actual collisions due to deformation of the structure, panic among passengers, or unfamiliarity with the operation, and C-EVFI has specifically included the mechanical lock function in the evaluation program.
Dr. Bin will also talk about the introduction of the new GB standard and what this means for the C-EVFI.
What is the idea behind the tests and assessment? What are the next steps? Is there a favourite technology that C-EVFI would like to see rolled out on the market?
Hear from Dr. Chen Bin and discuss C-EVFI's adaptation to the new regulatory landscape.
