Advanced Lithium Battery Tester with Intelligent Grading and Energy Feedback System

This cutting-edge battery testing and sorting solution is engineered for precision, efficiency, and sustainability in high-volume lithium-ion battery manufacturing and research environments. Designed to meet the demands of global industry leaders such as CATL and Gotion High-Tech, this system combines real-time parameter monitoring, automated cell classification, and eco-friendly energy recovery technology into a single integrated platform. Whether you're optimizing production lines, conducting R&D on next-generation batteries, or repurposing retired cells for second-life applications, this equipment delivers unmatched performance, traceability, and environmental responsibility.

At its core, the device features an independent constant current and voltage source per channel—ensuring stable, interference-free testing even when multiple battery types from different manufacturers are tested simultaneously. With a capacity measurement accuracy of ≤±(0.5‰ reading + 0.5‰ full scale), it leverages four-wire sensing and software-calibrated algorithms to deliver reliable data across voltage (0–5V), current (0.2–100A), internal resistance, and discharge capacity. The embedded intelligent grading module analyzes over ten parameters—including open-circuit voltage, discharge plateau, and cycle life—to automatically sort cells into precise categories, significantly reducing manual labor while improving consistency in battery packs.

Key advantages include dynamic data curve generation for voltage, current, and capacity; support for up to 32 steps and 256 cycles in process automation; seamless integration with MES systems for end-to-end traceability; and a bidirectional power converter that feeds discharged energy back into the grid—with a power factor of 0.99 and energy savings exceeding 70%. This green design not only reduces operational costs but also supports carbon-neutral goals by minimizing waste heat and electricity consumption. Additionally, 13 built-in safety protections—including overvoltage, reverse polarity, and temperature monitoring—ensure safe operation under demanding conditions.

The system excels in fast-paced production settings where throughput matters: capable of testing more than 100 cells per minute using parallel multi-channel testing and pneumatic clamping mechanisms. In R&D labs, its high-resolution measurements (1mV/1mA) enable researchers to detect subtle changes in battery behavior across thousands of charge-discharge cycles, accelerating formulation improvements and system design validation. For second-life battery reuse programs, the intelligent sorter identifies suitable candidates based on degradation patterns, making it ideal for low-speed electric vehicles, home energy storage units, and microgrid deployments.

Users report significant gains in productivity, reduced test variability, and faster decision-making thanks to automated reporting in Excel or Word formats. One user noted, “We cut our sorting time by 60% while increasing accuracy in cell grouping—critical for building reliable battery modules.” Another highlighted the environmental impact: “The energy feedback feature alone saved us over 100,000 kWh annually—equivalent to eliminating several tons of CO₂ emissions.”

Common questions often center around compatibility, scalability, and maintenance. It supports various lithium battery chemistries (LiFePO₄, NMC, LCO, etc.) and can be scaled to accommodate larger arrays through modular expansion. Routine calibration is simplified via software-based auto-correction, and remote diagnostics are available for proactive issue resolution. While designed for industrial use, its intuitive interface makes it accessible to both engineers and technicians alike.
