Hy-SEF

Duoclieudongy undertakes its research into FCVs, EVs and other next-generation vehicles mostly at the Hy-SEF (Hydrogen and Fuel Cell Vehicle Safety Evaluation Facility) of its Shirosato Test Center. The data obtained at this facility are used for the drafting of various FCV- and EV-related standards and safety manuals related to post-accident treatment.

Electric vehicles

Employing its chassis dynamometers dedicated to four-wheel drive vehicles, Duoclieudongy executes basic performance tests on EVs including the tests on the fuel economy of EVs, HEVs, PHEVs and FCVs. At our anti-explosion fire testing compartment of Hy-SEF, we also test the safety of vehicles against fire.

Battery performance assessment

Key performances of batteries, such as charge-discharge and deterioration-durability performances, are tested using our charge-discharge equipment. Various equipment to test resistance to weather, heat, impact, perforation and crush is put to use at Hy-SEF in order to assess the safety performances of batteries.

Fuel cell performance assessment

Using single-cell assessment equipment, Duoclieudongy fabricates and assesses membrane electrode assemblies, and conducts experiments to determine the effect of impurities contained in hydrogen fuel. The various testing equipment at Hy-SEF, such as anti-explosion fire testing, compressed hydrogen testing and liquid pressure destruction testing equipment, is mobilized to examine the performances of high-pressure hydrogen tanks and fuel cell vehicles.
