ODM S34E-256-10A Energy-Saving Battery Grading Cabinet – Precision Lithium-Ion Cell Testing & Sorting System

The ODM S34E-256-10A Energy-Saving Feedback Capacity Grading Cabinet is a high-performance, automated solution designed for accurate lithium-ion battery evaluation in industrial production environments. This advanced cell grading machine simulates real-world charge-discharge cycles to assess critical electrical parameters such as capacity, voltage stability, and internal resistance—enabling manufacturers to implement precise quality control at scale. By integrating sophisticated testing protocols with intelligent sorting logic, this system transforms raw battery cells into graded batches ready for assembly, significantly improving both throughput and consistency across battery manufacturing lines.

Engineered for reliability and energy efficiency, the S34E-256-10A delivers up to 0.05% measurement accuracy while maintaining exceptional operational stability. Its four-wire Kelvin connection ensures minimal signal interference during testing, making it ideal for high-precision applications in electric vehicle (EV), consumer electronics, and energy storage industries. The device supports polymer lithium-ion batteries with dual-side terminals, offering flexibility in handling various form factors commonly used in modern battery packs. With 256 independent channels, each equipped with its own dedicated current source, the unit enables simultaneous testing of multiple cells without cross-talk or performance degradation—a key advantage over traditional single-channel testers.

A standout feature of this battery tester is its bidirectional power conversion technology. During discharge, instead of dissipating energy as heat like conventional systems, the S34E-256-10A feeds recovered power back into the facility’s AC grid, achieving an impressive energy-saving rate exceeding 60%. This not only reduces electricity costs but also aligns with global sustainability goals by minimizing waste heat and lowering carbon emissions per unit produced. The integrated software platform offers intuitive human-machine interaction through a responsive interface, allowing operators to configure test profiles, monitor live data, and generate comprehensive reports—all from a connected computer.

This battery grading cabinet is part of a complete testing ecosystem that includes a scanning module, USB-to-485 communication adapter, and proprietary software for managing test sequences and classification rules. It's compatible with standard gray-white or gray-black chassis finishes (custom colors available) and uses durable blue-white split fixtures to securely hold cells during testing. Whether you're evaluating cylindrical, prismatic, or pouch-type lithium cells, this equipment provides consistent results across thousands of tests per day—making it a trusted tool for OEMs, battery pack assemblers, and R&D labs worldwide.

Common use cases include sorting lithium-ion cells based on capacity thresholds, identifying low-performing units early in the production cycle, and preparing homogeneous groups for Battery Module Assembly. Industries benefiting most from this system include EV battery manufacturers, portable power solutions providers, and renewable energy storage developers who require scalable, repeatable, and cost-effective battery screening methods.

Users consistently praise the system's combination of speed, precision, and energy savings. One operator noted, “We’ve cut our testing time by nearly 40% while reducing our power consumption dramatically—the feedback mechanism alone pays for the machine within months.” Another highlighted the ease of integration: “The software works seamlessly with our existing MES system, and the clear pass/fail indicators help our team sort cells faster than ever before.”

Q: How does the energy feedback system work? A: When discharging batteries, the unit converts DC output back to AC using a bidirectional inverter, feeding excess energy directly into the plant’s power supply rather than wasting it as heat. This results in substantial utility savings compared to resistive load-based testers.

Q: Is the system suitable for different battery types? A: Yes—it supports polymer lithium-ion cells with dual terminal configurations and can be adapted for other chemistries with appropriate fixture changes and software adjustments.

Q: What kind of maintenance is required? A: Minimal—regular cleaning of contact points and periodic calibration checks ensure long-term accuracy. No special tools or training are needed for routine upkeep.

For professionals seeking a robust, future-ready solution for lithium battery assessment, the ODM S34E-256-10A represents a significant upgrade in automation, efficiency, and environmental responsibility. Its ability to combine high-accuracy diagnostics with smart energy recovery makes it an indispensable asset in today’s competitive battery manufacturing landscape.
