Facilities
Four sites covering fire tests from small material specimens to 40 ft battery energy storage containers — over 20,000 m² in total.
Hebei large-scale fire test site
An outdoor site in a mountain valley built for full-scale fires of battery energy storage cabinets (10–20 MW) and containers (20–40 MW), with an 18 m × 13 m exhaust hood, 60 t lifting and remote observation. Co-built with Baoding Aidi New Energy.
| Built for | Outdoor cabinets 10–20 MW, BESS containers 20–40 MW (estimated peak heat release) |
|---|---|
| Exhaust hood | 18 m × 13 m, 17 m above ground |
| Exhaust duct | Ø 2.5 m, about 40 m long |
| Exhaust fans | 330,000 m³/h, with smoke treatment |
Jiading indoor large-scale fire hall
A 20 MW indoor fire test hall with a 25 m × 25 m exhaust hood 25 m high, co-built with Tongji University and in service. Used for fire tests of commercial and industrial energy storage and of vehicles.
| Heat release capacity | 20 MW |
|---|---|
| Exhaust hood | 25 m × 25 m |
| Height | 25 m |
| Typical tests | C&I energy storage cabinets, electric vehicles |
Nantong explosion test site
Huahui's own site for deflagration tests of energy storage products — from commercial and industrial cabinets to utility-scale BESS containers.
| Ownership | Owned and operated by Huahui Fire |
|---|---|
| Typical tests | Deflagration of C&I cabinets and utility-scale BESS containers |
| Measurements | Overpressure, impulse, vent opening, debris, flame jets, high-speed video |
