Lithium Ion Battery Tester

S37S-64-60A High-Precision Energy Regenerative Battery Tester for Lithium-Ion Cells

Engineered for precision, sustainability, and industrial-grade performance, the S37S-64-60A is a state-of-the-art battery charge-discharge testing system designed to evaluate cylindrical, prismatic, and custom polymer lithium-ion cells. With a 64-channel independent control architecture and an ultra-wide current range from 120mA to 60A, this multifunctional device delivers exceptional accuracy in both charging and discharging cycles while minimizing environmental impact through advanced energy regeneration technology.

Key Features

Energy Regeneration Efficiency

This battery load tester leverages third-generation regenerative power conversion to achieve up to 70% discharge efficiency and 80% charge efficiency—significantly reducing operational costs by as much as 30%. By feeding excess energy directly back into the electrical grid, it ensures a power factor exceeding 0.99, aligning with green manufacturing standards and enabling sustainable battery testing in high-volume production environments.

High Accuracy Measurement System

Equipped with a four-wire Kelvin sensing interface, the unit eliminates contact resistance errors, ensuring voltage and current readings within ±(0.5‰ reading + 0.5‰ full scale). This level of precision makes it ideal for research labs, R&D teams, and quality assurance departments requiring consistent, repeatable data across thousands of test cycles.

Comprehensive Safety Protocols

The system includes 13 layers of intelligent safety mechanisms such as reverse polarity detection, short-circuit protection, over-temperature shutdown, and real-time channel isolation. Each faulty channel triggers a tri-color LED alert, allowing immediate identification and resolution without interrupting other channels. A triple power-off safeguard ensures critical data remains intact during unexpected outages or emergency stops.

Detailed Description

Designed for versatility, the S37S-64-60A supports a wide variety of battery formats including standard 18650, 21700, and larger format pouch cells. It accommodates cylindrical batteries ranging from 32mm to 60mm in diameter and 80–200mm in length, while prismatic cells are accepted between 20–70mm thickness, 80–220mm height, and tab spacing of 60–150mm. Custom configurations for polymer lithium-ion cells can be programmed via its intuitive software interface, making it suitable for OEMs developing next-gen battery packs.

The device integrates seamlessly into automated production lines, offering programmable step sequences for dynamic cycle testing, capacity grading, and aging simulations. Its modular design allows easy expansion and maintenance, while built-in diagnostics provide predictive analytics for early failure detection. Whether used in EV battery pack validation, grid-scale energy storage systems, or academic research on battery degradation models, this equipment meets the demands of modern electrochemical analysis.

Applications Across Industries

In battery manufacturing, the S37S-64-60A enables rapid high-current testing (up to 60A) for evaluating fast-charging capabilities, thermal stability, and internal resistance behavior under stress conditions. For large-format battery integration projects like home energy storage or utility-scale solutions, it performs consistency checks on modules containing cells rated above 100Ah, ensuring uniform performance across thousands of units.

Researchers benefit from its ability to execute complex multi-step tests with sub-second timing precision, facilitating studies on cycle life, calendar aging, and SOC estimation algorithms. In battery recycling operations, the tester efficiently determines residual capacity and state-of-health (SOH) metrics for end-of-life cells, streamlining sorting processes for reuse or material recovery.

User Feedback Highlights

Users report that the S37S-64-60A has improved their throughput by up to 40% compared to older non-regenerative systems, primarily due to reduced cooling requirements and lower electricity bills. One lab manager noted, “The accuracy and repeatability have transformed our R&D workflow—we now get statistically significant results faster than ever before.” Another user in a battery factory added, “We’ve cut downtime by 60% thanks to the smart fault isolation—it’s like having 64 individual testers working together but with centralized monitoring.”

Frequently Asked Questions

Can this battery tester handle different chemistries beyond lithium-ion? Yes, while optimized for Li-ion, it supports nickel-metal hydride (NiMH), lithium iron phosphate (LiFePO4), and other common rechargeable battery types when configured appropriately.

Is there remote access capability? The system includes Ethernet connectivity for remote monitoring and data export via CSV or JSON formats, compatible with SCADA and MES platforms.

How does it reduce energy consumption compared to traditional testers? Through regenerative braking-like functionality, it converts waste heat and stored charge into usable power returned to the grid, eliminating the need for resistive load banks that dissipate energy as heat.
