TESTech TTech-CJPT Explosion-Proof Battery Disassembly Platform

Overview

The TESTech TTech-CJPT Explosion-Proof Battery Disassembly Platform is an engineered safety infrastructure system designed specifically for controlled disassembly of lithium-ion battery packs in R&D laboratories, failure analysis centers, and recycling pilot lines. It operates on a dual-protection principle: rapid physical containment and thermal quenching via submersion. When thermal runaway is detected—either manually triggered by operator intervention or automatically via optional integrated thermal sensors—the platform initiates a synchronized response: the battery module is mechanically lowered into a dedicated water-immersion tank, while a motorized, gasket-sealed explosion-resistant lid closes over the work chamber. This architecture mitigates fire propagation, suppresses off-gassing of HF, CO, VOCs, and other hazardous electrolyte decomposition products, and prevents secondary ignition events—critical for compliance with NFPA 855, UL 9540A pre-test handling protocols, and ISO 6469-1 safety requirements for electric vehicle battery service.

Key Features

• Integrated dual-stage safety actuation: manual emergency trigger + optional thermal sensor input (e.g., K-type thermocouple or IR array) for autonomous response within <2 seconds
• Stainless-steel structural frame (304 grade) with reinforced polycarbonate viewing window (12 mm thickness, ASTM D1709 impact-rated)
• Submersion tank with 40 L capacity, temperature-stable deionized water reservoir, and corrosion-resistant lift mechanism (IP65-rated linear actuator)
• Explosion-rated sealing lid: aluminum alloy housing with fluorosilicone gasket (rated to 20 bar peak pressure per EN 14460), pneumatically assisted closure
• Dedicated tool management tray with ESD-safe mounting points for torque-controlled screwdrivers, insulated pliers, and non-sparking pry tools
• Modular footprint (W1200 × D800 × H1800 mm) compatible with standard fume hood integration or standalone Class 10,000 cleanroom placement

Sample Compatibility & Compliance

The TTech-CJPT accommodates battery modules up to 1.2 m in length and 35 kg in mass—including EV traction packs (e.g., NCM811, LFP, and solid-state prototype formats), energy storage system (ESS) racks, and 18650/21700 cell arrays. All mechanical interfaces conform to IEC 62619 mechanical stress test requirements for secondary lithium cells. The platform’s containment performance has been validated per UN Manual of Tests and Criteria, Part III, subsection 38.3 (thermal runaway propagation test), demonstrating zero flame ejection and <5 ppm HF concentration in exhaust duct sampling during worst-case 3-cell cascade scenarios. Documentation supports GLP-compliant lab audits and satisfies OEM supplier qualification checklists (e.g., Tesla Q1, CATL SQM).

Software & Data Management

While the base TTech-CJPT operates as a hardware-integrated safety system without embedded firmware, it includes RS-485 and dry-contact I/O ports for integration into centralized lab monitoring systems (e.g., LabVantage, Siemens Desigo CC). Optional add-ons include: (1) a USB-connected data logger recording lid position, tank immersion status, and ambient temperature/humidity (±0.5 °C, ±3% RH); (2) audit-trail-enabled control panel with user login (role-based access), timestamped event logging (ISO/IEC 17025 traceability), and exportable CSV reports compliant with FDA 21 CFR Part 11 electronic record requirements. All firmware updates are delivered via signed .bin files with SHA-256 verification.

Applications

• Post-mortem analysis of failed Li-ion cells following abuse testing (nail penetration, overcharge, external heating)
• Electrode material recovery process development under inert or controlled-atmosphere conditions
• OEM warranty claim investigation requiring chain-of-custody preservation and gas emission characterization
• University research on thermal runaway chemistry, including in-situ FTIR gas sampling through standardized 6-mm NPT ports
• Recycling facility pre-processing of end-of-life EV batteries prior to hydrometallurgical separation

FAQ

Does the platform support automated thermal runaway detection?
Yes—when configured with optional thermal sensors and the TTech-SAFE controller module, the system detects ≥200 °C surface temperature rise at ≥50 °C/s rate and triggers full containment within 1.8 s.
Can the water tank be replaced with alternative quenching media?
No—the system is validated exclusively for deionized water. Substitution with polymer gels, salt solutions, or fire suppressants voids safety certification and compromises corrosion resistance.
Is the platform compatible with glovebox integration?
Yes—side-access ports (DN40 ISO-KF flanges) allow direct coupling to argon-purged gloveboxes for air-sensitive disassembly workflows.
What maintenance intervals are recommended?
Gasket inspection every 6 months; actuator lubrication and lid seal torque verification annually; full pressure-test validation every 24 months per EN 14460 Annex B.
Does TESTech provide installation and operator training?
Yes—on-site commissioning, SOP development support, and certified operator training (including simulated thermal runaway drills) are included in the TTech-CJPT Premium Support Package.
