ECS-GB Battery Pneumatic Shock Tester (200*200mm, 10 kg), EGBBPST

A Battery Shock Tester (Mechanical Shock Test System) is a high-precision engineering platform used to evaluate the structural integrity and safety of battery cells, modules, and packs when subjected to sudden, high-G deceleration. Unlike vibration testing, which involves continuous stress, a shock test simulates a single, catastrophic event—such as a vehicle collision, a hard drop during shipping, or an explosion. It is a mandatory requirement for certifications like UN 38.3 (Test T.4), UL 1642, and SAE J2464.

Pneumatic Shock Testers is using compressed air to propel the shock table toward an anvil, which achieves higher velocities in a smaller physical footprint. It offers superior repeatability, as the air pressure can be precisely regulated via a PLC. Since the shock tester can trigger an internal short circuit in a high-energy battery (especially in Sodium-ion or NCM chemistries), the tester must include: (1) Anti-Rebound Brake: A pneumatic brake that "catches" the table after the first impact. This prevents secondary bounces, which would invalidate the test and cause unnecessary damage. (2) Explosion-Proof Enclosure: A reinforced steel cabinet with heavy-duty latches and an observation window made of multi-layered tempered glass. (3) Exhaust & Fire Suppression: Integrated sensors for H2 or smoke that trigger an automatic Nitrogen (N2) purge or fire suppression system if the battery fails during the impact.
