ECS-GB Battery Drop Tester (Height: 300-1500 mm, 5 kg), EGBBDT

A Battery Drop Tester is a mechanical abuse testing platform designed to evaluate the safety and structural integrity of battery cells or packs when subjected to free-fall impacts. These systems are essential for certifying next-generation batteries (Sodium-ion, Solid-state) under international safety standards such as UN 38.3, IEC 62133, and UL 1642. The tester ensures that a battery can survive the rigors of transportation and accidental handling without leaking, venting, or entering thermal runaway.

Drop testing is not just about the height; it involves specific orientations and surfaces to simulate worst-case scenarios. (1) Drop Height: Most modern testers allow settings from 300mm to 1500mm for specialized R&D. (2) Drop Orientation: The battery must be dropped on multiple faces, edges, and corners (usually 6 orientations total) to ensure no "weak spots" exist in the housing or internal connections. (3) Impact Surface: Typically a hard, non-deformable surface such as a concrete floor or a 10mm+ thick steel plate.

Normally the battery drop testers are designed to provide a "pure" free fall with zero friction and maximum operator safety. (1) Pneumatic/Electromagnetic Gripper: These mechanisms hold the battery in a precise orientation. When triggered, they release the sample instantly, allowing it to fall without the "drag" or "spin" associated with manual drops. (2) Electric Lifting System: Controlled via a PLC (Programmable Logic Controller) and touch-screen HMI, allowing researchers to set the drop height with millimeter precision. (3) Reinforced Safety Chamber: Because a drop can trigger an internal short-circuit (especially in high-energy NCM or Sodium-ion cells), the tester is enclosed in a SUS 304 stainless steel cabinet with explosion-proof glass and chain-locked doors. (4) Pressure Relief Outlet: A dedicated vent on the top of the chamber that releases internal pressure waves safely if a battery explodes during the test.
