Battery Discharge Tester 0-150a Constant Current Discharge Gb/T 22473 Battery Performance Test Equipment

Battery Discharge Tester 0-150a Constant Current Discharge Gb/T 22473 Battery Performance Test Equipment

Product Introduction

• Multi-mode Discharge: Supports independent, parallel (master/slave), and remote control modes. It can adjust the current from 0-150A and is suitable for 38-132V DC battery packs (mainly 48V/110V), simulating real discharge scenarios.
• Wireless Cell Monitoring: Uses multi-band RF wireless modules (communication distance >100m), compatible with 2V/4V/6V/12V cells. It can monitor up to 300 cells (25 groups × 12 cells), collecting cell voltages in real-time (precision ±0.05%), avoiding wired connection risks and improving test safety.
• Data Management: Built-in 8G SD card + 16G U disk store discharge data (total voltage, current, cell voltage, etc.). Data is transmitted to the upper computer via RS485/USB, generating curves and reports (such as capacity decay, voltage fluctuation analysis). It supports Chinese-English touch operation (7-inch HD screen) with a user-friendly interface.
• Protection and Safety: PTC ceramic resistors avoid red heat, with overvoltage (≥38V shutdown), overcurrent (>150A protection), reverse connection, and 65℃ overtemperature protection. It has sound and light alarms + screen prompts, complying with EN610950 safety standards, ensuring a risk-free test process.

Product Features

1. Safe Discharge: PTC resistors without red heat, forced air cooling (noise <75dB), suitable for -5-50℃ working environment, stable operation at 4000m altitude.
2. Wireless Monitoring: 4-band RF communication, up to 4 systems working simultaneously without interference; 3 data collection methods (host, USB terminal, hybrid transmission), cell voltage displayed as sliding/bar graphs, automatically screening extreme value cells (top 6 high/low voltages).
3. Intelligent Control: ARM microcontroller + capacitive touch, 7-inch HD screen, built-in Chinese-English menu; supports online compensation discharge (external clamp sensor), suitable for single-group battery test scenarios.
4. Multi-machine Parallel: Master-slave mode, evenly distributing power, simplifying multi-device collaborative operation, improving test efficiency (such as large-capacity battery pack discharge).
5. Comprehensive Protection: Overvoltage, undervoltage, overcurrent, reverse connection, overtemperature protection, automatic shutdown with reason recording, buzzer + screen prompt, complying with electrical strength test (input-housing 2200Vdc for 1 minute).
