lithium ion battery production equipment

The DC Resistance Tester is a high-precision, intelligent battery testing solution designed for modern manufacturing, research and development, and quality assurance environments. This advanced equipment excels in measuring both the direct current (DC) internal resistance and open-circuit voltage of batteries with exceptional accuracy, making it an indispensable tool in battery performance evaluation systems. Whether used as a standalone tester or integrated into automated production lines via AGV carts for loading and unloading, this system streamlines operations while enhancing throughput and reliability. At its core, the device combines precise hardware components with robust software control, enabling seamless automation through PLC integration and compatibility with MES platforms. Its modular architecture simplifies maintenance and component replacement, ensuring minimal downtime and long-term operational efficiency. The tester supports multiple charge-discharge profiles—including constant current with voltage limits, constant power modes, and custom cycle conditions—allowing users to simulate real-world usage scenarios for comprehensive battery assessment. Key technical specifications include a current measurement accuracy of ±0.05% full scale and a voltage resolution down to 0.1 millivolts, delivering highly reliable data for critical applications. Energy efficiency is also prioritized, with a power factor exceeding 95% and energy recovery rates above 70%, reducing overall operating costs and environmental impact. The unit is compatible with various battery formats, notably 22400 cylindrical cells, and features flexible communication interfaces such as Ethernet, RS485, and CAN protocols, facilitating smooth integration into existing industrial ecosystems. In production settings, this tester acts not only as a performance validation instrument but also as a smart sorting machine. By analyzing test results in real time, it automatically classifies batteries based on parameters like resistance, capacity, and consistency—enabling manufacturers to enhance product uniformity, reduce defects, and optimize yield. For R&D teams, the rich dataset generated during multi-cycle tests provides deep insights into battery behavior under different stress conditions, supporting innovation in cell chemistry, thermal management, and longevity optimization. Quality inspectors benefit from traceable data logs that support compliance reporting, root cause analysis, and continuous improvement initiatives across the supply chain. Users consistently praise the system’s stability, ease of use, and ability to deliver actionable intelligence without requiring extensive training. Many report significant reductions in manual inspection efforts and improved decision-making due to accurate, exportable results in Excel format. The built-in safety mechanisms—such as overcurrent, overvoltage, and temperature protection—ensure safe operation even in demanding environments, reinforcing trust in the testing process. Common questions often revolve around setup complexity, but most operators find the intuitive interface and clear documentation make deployment straightforward. Another frequent inquiry concerns compatibility with legacy systems; the device’s versatile connectivity options ensure it can be adapted to diverse factory infrastructures. While some may initially question the investment, the return on value becomes evident through faster testing cycles, reduced waste, and enhanced product quality—making this DC Resistance Tester a strategic asset for any battery-focused operation worldwide.
