Introduction
Modern battery production facilities require testing equipment with integrated data management and control capabilities. The XWELL XW-5V300A16CH Prismatic Battery Cell Grading Machine operates under computer control with whole cabinet integration and a scanning system. An STM32 single-chip microcontroller manages equipment functions and connects to a computer that stores all test data and curves. The system records voltage, current, time, and capacity at 1-second intervals across all 16 channels, providing a comprehensive data record for battery cell grading, sorting, and quality analysis.
Main Functions
Computer-Controlled Whole Cabinet Operation
The XW-5V300A16CH operates under computer control with whole cabinet integration and a scanning system. This control architecture enables centralized management of all 16 channels, including process programming, test execution, data recording, and status monitoring from a single computer interface.
1-Second Interval Data Recording
The system records voltage, current, time, and capacity data at 1-second intervals for every channel during testing. This recording frequency captures detailed charge and discharge characteristic curves, supporting comprehensive analysis of battery cell performance across all 16 channels.
STM32 Microcontroller Integration
The equipment is controlled by an STM32 single-chip microcontroller connected to the host computer. This architecture supports reliable equipment operation while enabling computer-based data storage, curve analysis, and test program management for all 16 channels.
Graphical Interface with Real-Time Parameter Display
The operation interface simultaneously displays voltage, current, time, and capacity for each battery under test. Configurable color coding differentiates working statuses and abnormal conditions, providing intuitive visual monitoring during production-scale testing.
Direct Keyboard Operation Capability
In addition to computer control, the equipment supports direct operation through a built-in keyboard for setting process parameters and executing test and sorting functions. This dual-mode operation provides flexibility for different production workflow requirements.
Complete Test Data Storage and Curve Analysis
All test data and measurement curves are stored on the connected computer system, enabling post-test analysis, cell grading decisions, and quality documentation. The system retains both measurement values and status records for each channel throughout the test duration.
