Rechargeable Battery Automatic Testing Formation and Capacity Grading Equipment High Precision Cell Capacity Grading Cabinet

Product Overview

This high-throughput battery testing system is engineered to provide precise formation, degradation screening, and capacity grading for commercial secondary cells. Designed to manage up to 512 channels simultaneously, the equipment integrates independent constant current and constant voltage power sources across every individual channel, eliminating cross-talk and ensuring uniform electrochemical processing across entire production batches.

Built for both pilot-scale development and high-volume manufacturing environments, this cabinet supports standard cylindrical formats and polymer pouch cells. It delivers rapid, automated workflow execution—spanning primary electrolyte soaking, initial solid electrolyte interphase (SEI) formation, high-rate discharge capacity verification, and automated binning based on multidimensional electrical parameters.

Equipped with dedicated AVR microcontroller architecture and high-precision sampling circuitry, this system maintains exceptional operational stability under continuous industrial duty cycles. Real-time data acquisition, zero-surge CC-to-CV transitions, comprehensive fail-safe protections, and non-volatile power-loss recovery combine to safeguard sensitive battery chemistries and preserve critical test records.

Key Features

• 512 Completely Independent Channels: Each channel utilizes a dedicated constant current and constant voltage hardware circuit, establishing a fully isolated loop that prevents inter-channel interference and guarantees individual cell testing integrity.
• Impact-Free CC-CV Switching: Advanced power electronics deliver ultra-smooth transitions from constant current to constant voltage charging without electrical surges or voltage spikes, preventing lithium plating and protecting cell microstructures.
• Dual Standalone and Host PC Modes: The system operates seamlessly under centralized computer control for comprehensive curve generation or in standalone mode via the built-in control panel for immediate routine cycling and time-based sorting.
• Integrated Visual Binning Indicators: Every fixture location features an independent LED indicator that illuminates real-time operational states and automatically signals capacity sorting tiers immediately upon discharge completion.
• Multidimensional Sorting Algorithms: Powerful software facilitates cell grading based on capacity thresholds (up to 100 customizable segments), time, open-circuit voltage (OCV), discharge voltage plateaus, and coulombic efficiency calculations.
• Advanced Step and Cycle Programming: The central supervisory interface allows configuration of up to 32 custom operational steps per program and up to 256 execution cycles per testing regime.
• Non-Volatile Power-Loss Recovery: Built-in hardware memory instantly captures operational states during power interruptions, automatically resuming pre-outage test sequences upon power restoration without data corruption.
• Synchronized Fast-Sampling Architecture: Precision peripheral sampling circuits monitor voltage, current, and accumulated capacity across all 512 channels with a rapid scan cycle of ≤10 seconds per full-cabinet sweep.
• Granular User Permission Hierarchy: Multi-tier software authentication safeguards standardized testing recipes, restricts configuration access, and prevents unauthorized operational modifications.
