Controlled Fire Exposure for EV Battery Cells and Small Test Articles
The DERUI DR-D211 EV battery cell fire exposure tester applies a controlled gas flame to a secured test article so R&D teams can observe ignition, casing response, venting, burning and fragment behavior under a defined laboratory procedure.
What the DR-D211 Can—and Cannot—Evaluate
The system is suited to comparative external-flame exposure of cells, steel-shell battery specimens and small assemblies within its size and mass limits. It can help characterize visible fire response, but it is not automatically a calorimeter, gas-analysis system, full pack fuel-fire bench or certification laboratory.
Cell Design Screening
Compare casing, vent and protective-design behavior under the same burner setup and observation procedure.
Materials and Enclosure R&D
Observe whether housings, shields and nearby materials ignite, deform, detach or permit fragment release.
Failure Documentation
Record flame time, visible events, surface temperatures and video when the configured instrumentation supports them.

Instrumentation Is Configuration-Dependent
The old page promises pressure, gas-emission sensing, automatic suppression, data acquisition and report generation, but these are absent from the technical table. Treat them as optional until documented.
Information Needed Before Configuration
Define the Specimen
Chemistry, format, dimensions, mass, energy, state of charge, enclosure and expected failure modes.
Define the Exposure
Standard/method, fuel, flame dimensions and temperature, distance, duration, airflow and termination criteria.
Define the Measurements
Thermocouples, voltage, video, pressure, gas sampling, heat-release measurement and event timing.
EV Battery Cell Fire Tester FAQs
What does the DR-D211 test?
It applies a controlled gas flame to a cell or small battery specimen so visible fire response and selected measurements can be documented under a defined procedure.
Is it a thermal-runaway propagation tester?
Not by itself. Propagation testing requires a defined initiation method, neighboring cells/modules, instrumentation and acceptance criteria.
Does it comply with UL 9540A?
The complete UL 9540A method is broader than this device. A qualified laboratory must determine whether this equipment supports any particular activity in its test plan.
Can it run UNECE R100 pack fire exposure?
Not based on the supplied specifications. UNECE R100 uses a REESS/vehicle-scale fuel-pan procedure that differs in specimen size and flame arrangement.
Why was ASTM E3189 removed?
ASTM E3189 concerns fire-debris sample preparation for ignitable-liquid residue analysis; it is unrelated to battery fire-resistance equipment.
What specimen size is supported?
The stated maximum envelope is 400 × 400 × 200 mm and maximum mass is 20 kg. Fixture, clearance and risk limits may reduce usable capacity.
Does the tester include gas analysis and suppression?
They are not confirmed in the supplied parameter table. Add them only if included in the approved configuration and facility safety design.
What should I provide for quotation?
Send chemistry, dimensions, mass, energy, SOC, procedure, burner/exposure details, measurements, exhaust and facility safety requirements.
Review the Fire Procedure and Facility Together
Send DERUI the specimen, energy and state of charge, applicable method, flame exposure, instrumentation and site fire-safety plan. We will confirm whether DR-D211 fits the test and which options are required.
