Pin Bed Cylindrical Battery Formation and Capacity Grading System with Energy Feedback

Product Overview

This high-precision energy-regenerative pin-bed battery formation and capacity grading system is engineered for industrial-scale manufacturing and quality classification of cylindrical lithium-ion cells. Built upon an advanced two-stage modular topology, the equipment delivers independent channel-level control, industry-leading voltage and current measurement accuracy, and bi-directional power conversion that recycles energy back into the facility power grid during cell discharge cycles.

Designed specifically for commercial cylindrical cell production facilities, pilot lines, and battery research laboratories, this system integrates high-density multi-tier pneumatic pin-bed fixtures with distributed digital signal processing. It executes critical cell processing steps including constant current (CC) charging, constant voltage (CV) charging, constant current (CC) discharging, capacity sorting, internal resistance analysis, and multi-tier rest stages under rigid safety monitoring protocols.

By replacing conventional resistive load dissipation with high-efficiency regenerative power electronics, this unit cuts overall production electricity demand by up to 50% while mitigating factory thermal loads by 5°C to 15°C. With an industrial-grade digital signal processor (DSP) core, power factor exceeding 0.99, total harmonic distortion under 5%, and an MTBF rating of 30,000 hours per power module, the equipment ensures continuous, unattended 24/7 industrial performance.

Key Features

• High-Efficiency Energy Regeneration: Integrated bi-directional power conversion modules feed discharge energy directly back into the AC grid with overall feedback efficiency exceeding 65% and charge efficiency above 70%, slashing operational electricity costs by half compared to conventional non-regenerative grading equipment.
• Pneumatic Pin-Bed Automation: High-density 768-channel structural architecture arranged in three 256-channel tiers provides rapid mechanical clamping, low contact resistance, and uniform thermal dissipation across all cylindrical cells simultaneously.
• Distributed Digital Signal Architecture: Real-time sampling and signal filtering occur at the low-level channel hardware via industrial DSP controllers, eliminating analog transmission interference and ensuring pristine data integrity across all 768 channels.
• Grid-Friendly Power Factor and Low Harmonics: Advanced active power factor correction achieves a power factor greater than 0.99 under full-load conditions with Total Harmonic Current Distortion (THDI) below 5%, eliminating electrical pollution and safeguarding facility electrical infrastructure.
• Independent Multi-Step Channel Control: Each channel operates autonomously across 0–5V charge and 2–5V discharge profiles (20mA to 6A), supporting millivolt-level voltage precision (±3mV) and current precision of ±(0.05%FS + 0.05%RD) with ultra-fast 50ms transient response.
• Multi-Tier Hardware and Software Safety Interlocks: Configurable safety thresholds cover over-voltage, under-voltage, over-current, reverse polarity, contact impedance deviation, and thermal runaway, instantly isolating faulted channels without interrupting adjacent cell tests during unattended operation.
• Centralized Multi-Unit Network Management: Industrial 10M Ethernet connectivity enables a single supervisory control PC to simultaneously manage, monitor, and log comprehensive data curves for up to 6 formation cabinets (4,608 total cell channels).
• High Ambient Thermal Stability: By regenerating discharge power rather than venting it as heat, the equipment reduces shop floor ambient temperatures by 5°C to 15°C, drastically lowering facility HVAC cooling load and extending electronics operational lifespan.
