ZXFD Intelligent Battery Discharge Tester: Technical Overview

The ZXFD Intelligent Battery Discharge Tester is a professional-grade instrument designed for comprehensive performance testing and capacity evaluation of lead-acid battery banks, primarily those used in DC power systems and Uninterruptible Power Supplies (UPS). It provides technicians with a reliable, precise, and user-friendly solution for preventive maintenance and battery health assessment.

Core Technical Features

1.Safe & Durable Load Technology: Utilizing advanced PTC (Positive Temperature Coefficient) ceramic resistors, the tester ensures inherently safe operation by preventing the "hot-red" phenomenon common in traditional resistive loads. This design significantly enhances operational safety and extends the equipment's lifespan.

2.Intelligent Control & Interface: At its heart is an ARM-based intelligent microcontroller, offering precise control and logical workflow management. It is paired with a large LCD touchscreen, providing a clear English menu-driven interface for intuitive operation and real-time data visualization.

3.Advanced Wireless Data Acquisition: A key innovation is the wireless communication between the main load unit and the distributed Data Acquisition Cases (DACs). This eliminates cumbersome wiring, especially in large battery banks. The wireless DACs enable simultaneous monitoring of individual cell voltages, providing critical insight into cell balance and identifying weak units.

4.Flexible & Programmable Test Regimes: Technicians can configure discharge tests by setting multiple stop conditions:

Single Cell Voltage (min/max)

Overall Battery String Voltage

Discharge Current

Discharge Duration (Time)
This flexibility allows for standardized capacity tests (e.g., C10 discharge) or customized diagnostic procedures.

5.Comprehensive Data Logging & Analysis: The system continuously records key parameters throughout the discharge cycle, including:

Total string voltage and current

Cumulative discharge capacity (Ah)

Voltage trends of the weakest individual cell
Data is automatically saved and can be exported via USB to a U盘 (USB flash drive). The accompanying PC software allows for in-depth analysis, report generation, and graphical charting of the discharge curves.

Technical Specifications

1.Power Input: AC 220V or DC 110V-220V (directly from the battery bank under test).

2.Supported Battery Voltages: DC 48V, 110V, 220V, 380V.

3.Discharge Current Range: 0-300A (for 48V system); 0-250A (for 110V/220V/380V systems).

4.Discharge Cut-off Voltage Range: Adjustable within set ranges for each battery voltage grade (e.g., 176-264V for a 220V bank).

5.Accuracy: Discharge current accuracy is within ±1%.

6.Resolution: Current resolution of 0.1A or 1%; Voltage resolution of 0.5%.

7.Communication: USB and RS232 interfaces.

8.Data Sampling Interval: 10 seconds.

9.Operating Environment: Temperature 0°C to +50°C; Humidity 5% to 90% (non-condensing).

10.Cooling: Forced air cooling.

Application Value for Technicians

For technical personnel, the ZXFD tester transforms battery maintenance from a simple voltage check into a diagnostic science. Its ability to conduct a controlled, monitored, and documented discharge test under programmable conditions allows for:

1.Accurate Capacity Verification: Determining the actual available capacity versus the rated capacity.

2.Weak Cell Identification: Pinpointing underperforming cells that may degrade overall bank performance.

3.Predictive Maintenance: Forecasting battery end-of-life and planning replacements proactively.

4.Performance Benchmarking: Creating historical records for trend analysis over multiple test cycles.

5.Safety Enhancement: Conducting high-current discharge tests safely with its PTC load and comprehensive monitoring.

In summary, the ZXFD Intelligent Battery Discharge Tester integrates robust hardware design with sophisticated software control and wireless monitoring. It serves as an essential tool for technicians responsible for ensuring the reliability and longevity of critical lead-acid battery backup systems.
