Product Description

Overview

Accurate voltage and current measurement is critical for battery cell grading and quality classification in lithium battery production. The XWELL XW-5V300A16CH Prismatic Battery Cell Grading Machine provides voltage measurement with 0.1mV resolution and control accuracy of ±(0.5‰ reading + 0.5‰ full scale), combined with current measurement at 1mA resolution and matching accuracy. This measurement performance, implemented through a four-wire test interface across 16 independent channels, supports precise cell classification based on charge and discharge characteristics.

Core Functions

0.1mV Voltage Measurement Resolution

The XW-5V300A16CH achieves voltage control and sampling resolution of 0.1mV across a measurement range of DC 0V to 5V. The constant voltage range spans DC 2V to 4.5V, supporting precise voltage control during charge and discharge cycles for prismatic battery cells.

1mA Current Measurement Resolution

Current control and sampling resolution reaches 1mA within the charge and discharge current range of 600mA to 300A. Combined with time measurement control accuracy of ≤±0.1%, this enables precise tracking of battery capacity during test cycles.

Four-Wire Test Interface Design

The equipment employs a four-wire (Kelvin) connection method to eliminate lead resistance effects on measurement accuracy. This measurement configuration maintains the rated voltage and current accuracy specifications across all 16 channels during simultaneous operation.

Stable Constant Current and Constant Voltage Sources

Each channel incorporates an independent constant current and constant voltage source designed for stable, shock-free operation. The system records measurement data at 1-second intervals, capturing detailed charge and discharge characteristic curves for each cell under test.

STM32 Microcontroller-Based System Control

The machine operates under STM32 single-chip microcontroller control connected to a computer system. All test data and measurement curves are stored for subsequent analysis, with graphical interface display of real-time parameters across all channels.

Comprehensive Charge Discharge Mode Support

Supported charge and discharge modes include constant current, constant voltage, constant current constant voltage, constant power, and constant resistance. Charging cut-off conditions can be set by voltage, current, time, capacity, or -ΔV; discharge cut-off by voltage, time, or capacity.
