ECS-GB Battery Burning Tester (Flame Height: 10-75 mm), EGBBBT

A Battery Burning Tester (often referred to as a Projectile Test Machine) is an extreme-environment safety evaluation platform. Its primary function is to subject a battery to direct flame or intense heat to observe its reaction—specifically to see if it explodes, catches fire, or releases dangerous projectiles. This equipment is mandatory for certifying batteries under international safety standards such as UL 1642, UL 2054, UN 38.3 (T.6), and IEC 62133.

Projectile Test (Flame Exposure): A single battery is placed on a wire screen (stainless steel mesh) over a burner. Then a Bunsen burner (or similar gas burner) is ignited under the battery, heating it until it either explodes or is completely consumed. An aluminum mesh octagonal cage (the "test cage") is placed around the setup. To pass, the battery may catch fire or explode, but no part of the battery (shrapnel) can penetrate the aluminum mesh or throw debris beyond the designated safety zone.

Because these tests are intentionally destructive, the hardware is built for extreme durability and operator safety. (1) Burner System: A high-precision gas burner (Propane or Methane) with an automated ignition system. The flame height (typically 38 mm) and temperature (800 °C) must be strictly controlled. (2) Screen/Grid: A stainless steel wire mesh (20 openings per inch) that supports the battery during heating. (3) Projectile Cage: A standardized aluminum mesh enclosure designed to capture shrapnel. The dimensions and mesh density are dictated by standards like UL 1642. (4) Remote Control & HMI: For safety, the operator controls the burner, timing, and exhaust from a remote PLC-based console located in a separate room or behind a blast shield.
