Heavy Weight Impact Test Machine for Battery Safety Testing

Product Overview

This heavy weight impact test machine is engineered to evaluate battery safety under a controlled mechanical impact event. A specified 9.1 kg weight is released vertically onto a 15.8 mm cross bar positioned over the battery sample, enabling repeatable testing at a controlled drop height. The required assessment outcome is that the tested battery does not catch fire or explode after impact.

The equipment supports battery safety laboratories, cell manufacturers, battery research centers, and quality teams that need to examine a cell's response to severe external mechanical abuse. Its adjustable 0 to 700 mm drop-height range accommodates prescribed 610 mm testing as well as other height settings within the available range. Each battery sample receives one impact, while each subsequent test uses a different sample.

Built as a protected, enclosed test station, this system combines a reinforced access door, protected observation window, pressure-relief provision, stainless-steel internal test area, and a dual-column dropping arrangement. PLC touch-screen operation provides direct parameter visibility and practical day-to-day control for demanding battery safety test workflows.

Key Features

• Controlled 9.1 kg Impact Mass: The supplied impact weight is specified at 9.1 kg +/- 0.1 kg, providing a defined loading condition for battery impact safety evaluation. This controlled mass helps laboratories maintain a consistent mechanical test input across separate samples and test sequences.

• Adjustable Vertical Drop Height: Electric lifting supports an adjustable drop height from 0 to 700 mm, with intelligent control centered on the commonly required 610 mm setting. The mechanism raises the weight to the selected position and releases it for a vertical free fall without tilt or sway.

• High-Resolution Height Indication: Encoder-based height display and PLC touch-screen parameter presentation provide a display precision of 0.1 mm. With a specified height error of +/- 5 mm, operators can set and review the selected impact height with useful control over a key test variable.

• Dual-Column Free-Fall Arrangement: The two-column construction reduces friction between the falling weight and the enclosure walls. It is designed to support an unobstructed vertical drop while also addressing operational safety around the moving impact assembly.

• Defined Steel Cross-Bar Interface: A 15.8 mm +/- 0.1 mm diameter bar, at least 60 mm long, is included as standard. Positioned vertically across the center of the battery and maintained parallel to the bottom surface of a prismatic battery, it creates the prescribed concentrated impact condition when struck by the weight.

• Reinforced Containment Enclosure: The front door uses an enhanced structure with exposed heavy-duty hinges on the left and a strong locking clasp on the right. These purpose-designed reinforced components help keep the enclosure securely closed during testing.

• Protected Viewing and Internal Lighting: The 390 x 360 mm viewing window uses 20 mm thick tempered explosion-proof glass with explosion-proof film and an added protective steel mesh. External lighting reflects into the inner chamber, allowing operators to observe the test area while keeping the lighting source outside the chamber.

• Independent SUS 304 Test Zone: The enclosure contains one independent test area made from SUS 304 stainless steel. The inner-box material is 1.0 mm thick with reinforcement, while the stated combined inner and outer enclosure thickness is 80 mm, supporting a durable laboratory test environment.

• Automatic Pressure-Relief Provision: A pressure-relief device is installed at the upper rear of the enclosure bottom. When pressure reaches the pressure-switch setting, the pressure door opens automatically to release pressure.

• Mobile, Practical Laboratory Installation: Four casters at the base allow the unit to be moved and fixed in position. A rear-mounted 100 mm diameter exhaust port with exhaust fan supports enclosure ventilation as part of the installation arrangement.

Why Choose This Product

• Purpose-Built Impact Configuration: The supplied 9.1 kg impact weight and 15.8 mm cross bar provide the defined mechanical interface required for the stated battery impact method. Adjustable height control adds practical flexibility while preserving the prescribed 610 mm test setting.

• Precision-Focused Test Setup: Encoder height indication, 0.1 mm display precision, and a specified +/- 5 mm height error make the selected drop height visible and manageable. The vertical electric-lifting and dual-column drop arrangement are designed to maintain a stable, free-fall impact path.

• Robust Protective Construction: Reinforced door hardware, a protected tempered-glass viewing window, steel mesh, SUS 304 internal construction, steel impact surfaces, and automatic pressure relief reflect the equipment's emphasis on enclosed test operation.

• Efficient Operator Control: PLC touch-screen control puts test parameters in a direct, easy-to-view interface. External reflected lighting and the observation window help personnel monitor the internal test area without placing the lamp inside the chamber.

• Practical Laboratory Deployment: The independent test area, rear exhaust arrangement, and lockable mobile base support integration into battery test facilities where equipment positioning, observation, and controlled test handling matter.
