Battery Cell Charge-Discharge Test System
Product Introduction
This system is a core equipment specifically designed for performance verification and quality evaluation of lithium battery cells. It can not only complete basic tests such as capacity, energy, and efficiency but also further support complex requirements in the process of cell R&D and production. Adopting a modular and multi-channel design, the system can simultaneously test hundreds of cells in parallel, meeting the full-process testing needs from material R&D, lab-scale trial, pilot-scale trial to final finish grading on the production line.
Through high-precision current/voltage control and rich test step editing functions, it can simulate various actual operating conditions, accurately evaluate the cell's rate performance, cycle life, self-discharge characteristics, and performance under different temperature ranges. It provides a reliable data foundation for cell design optimization, process improvement, and batch consistency control.
Product Features
● Ultra-High Precision and Stability: Equipped with a 24-bit high-precision ADC and a low-temperature-drift reference source, the voltage measurement accuracy is better than ±0.015% FS, and the current accuracy is better than ±0.02% FS. This ensures the absolute reliability of long-term cycle test data, especially suitable for detailed analyses such as SOC-OCV curve calibration and Coulombic efficiency calculation.
● Flexible Channel Configuration and Energy Management: Supports flexible configuration and expansion of 8 to 256 channels. It has an efficient energy feedback function, where the discharged energy can be fed back to the power grid with a feedback efficiency of >85%, significantly reducing the operational energy consumption of large-scale test laboratories or production lines.
● Intelligent Software and Data Analysis: Equipped with professional test software that supports custom multi-step test processes and automatic report generation. Built-in basic algorithms can perform trend analysis on cycle data and capacity attenuation fitting, and support one-click data export to third-party analysis platforms.
