The A39-48-150A Bed-of-Nails Type Power Battery Capacity Grading Equipment is a state-of-the-art automated testing system engineered for precision lithium-ion battery capacity assessment in industrial and research environments. Designed specifically for aluminum-cased prismatic cells, this advanced battery tester delivers high-throughput performance across 48 channels simultaneously, enabling efficient and accurate grading during formation and quality control processes. With its innovative bed-of-nails interface, the device supports customizable fixtures tailored to varying battery dimensions—ranging from 5mm to 16mm in thickness and 20mm to 130mm in tab spacing—ensuring compatibility with diverse cell models used in EVs, energy storage systems, and consumer electronics. At the heart of this power battery tester lies a robust four-wire measurement architecture combined with independent constant-current and constant-voltage sources, achieving voltage and current accuracy within ±0.5‰. The unit’s programmable charge profile includes up to 64 customizable steps, allowing detailed control over charging protocols such as CC/CV (constant current/constant voltage) sequences—an essential feature for optimizing battery aging studies and cycle life analysis. In addition to superior electrical precision, the A39-48-150A integrates an intelligent energy feedback mechanism that recycles excess power during discharge cycles, resulting in over 80% charging efficiency and more than 60% reduction in overall energy consumption compared to traditional testers. This makes it not only environmentally responsible but also economically advantageous for continuous operation in production lines or R&D labs. Key features include comprehensive safety mechanisms like reverse polarity protection, capacity outlier detection, real-time temperature monitoring per layer, and integrated smoke alarms—protecting both equipment and personnel from potential hazards. Data management capabilities are equally impressive: seamless integration with MES (Manufacturing Execution Systems) enables automatic Excel report generation, capturing live voltage, current, and capacity metrics while calculating discharge efficiency and enhancing traceability throughout the manufacturing process. These functions collectively reduce manual data entry errors and accelerate decision-making in battery production workflows. This lithium-ion battery capacity grading machine excels in multiple application scenarios. On power
Battery Assembly lines, its synchronized multi-channel testing boosts throughput significantly while maintaining consistent grading accuracy—critical for improving yield rates and product uniformity. For energy storage applications, the wide range of compatible cell formats allows rapid screening of aluminum-cased batteries, making it ideal for pre-packaging validation in large-scale battery packs. Researchers benefit from its deep programmability and extensive logging options, which facilitate experimental design, material evaluation, and performance benchmarking of next-generation battery chemistries. Whether deployed in smart factories or university laboratories, the A39-48-150A stands out as a versatile solution for modern battery testing needs. Users have consistently praised the system's reliability under heavy-duty conditions, noting how its modular design simplifies maintenance and reduces downtime. Many highlight the ease of integrating cloud-based analytics tools, which streamline compliance reporting and support predictive maintenance strategies. Others commend the intuitive software interface that enables non-expert operators to run complex tests without extensive training—a major advantage in fast-paced manufacturing settings. Common inquiries often center around setup flexibility and scalability. While the bed-of-nails configuration requires initial fixture customization, most customers find the investment worthwhile due to long-term adaptability across different battery sizes. Regarding throughput, users confirm that the 48-channel parallel testing capability dramatically shortens test durations compared to single-cell systems, especially when processing thousands of cells daily. Energy savings from the feedback system are frequently cited as a key selling point, particularly in facilities where operational costs directly impact profitability. In summary, the A39-48-150A represents a powerful convergence of automation, precision engineering, and sustainability in battery testing technology. Its ability to handle demanding industrial tasks while supporting cutting-edge research positions it as a top-tier choice for anyone involved in lithium-ion battery development, production, or quality assurance worldwide.
