The HZXD-F-38-600V/30-50A is an intelligent storage battery discharger and capacity tester designed for battery packs rated 12V, 24V, 48V, 110V, 220V, 380V, and 480V. It performs checking discharge tests, remaining capacity tests, routine battery maintenance, and load-capacity inspection of DC power supplies.

Based on the discharge characteristics of lead-acid and lithium batteries, the tester monitors battery voltage, discharge current, discharge duration, discharge capacity, and other parameters in real time throughout the discharge process. An embedded operating system automatically completes the entire discharge cycle for fully intelligent operation. The device generates curves, bar graphs, and reports that intuitively reflect battery group performance, all of which can be enlarged, queried, and printed. This makes battery pack maintenance and management easier and more scientific, helping to extend the service life of the battery pack.

The power consumption element uses a new PTC design that is small, lightweight, and easy to move. The whole machine is controlled by a microprocessor with an LCD display and menu interface. It is widely used in communications, electric power, tower, battery manufacturing, new energy vehicle enterprises, railroad, subway, petrochemical, and other industries. With easy operation and safe discharging, it is an ideal test tool for DC system operation and maintenance testing.

When used together with the wireless single-cell inspection module, the device can effectively monitor the voltage of individual cells in a battery pack and promptly identify faulty batteries with serious performance deterioration.

1. Constant current discharge for battery packs: The constant current discharge current is continuously adjustable, allowing precise measurement of battery pack capacity.
2. Wide test voltage range: Covers 38–600V battery pack discharge testing with a maximum discharge current of 50A. One machine serves multiple purposes, meeting test requirements for battery packs at various voltage levels (12V/24V/48V/110V/220V/380V/480V).
3. Safe polymer PTC discharge: The product discharges through a Polymeric Positive Temperature Coefficient resistance with a high safety coefficient, avoiding red-heat phenomena and providing stronger environmental adaptability for a safer, more stable discharge test.
4. Imported STMicroelectronics ARM CPU: The main control board uses a high-performance ARM CPU from STMicroelectronics with stable performance, high frequency, and powerful processing. The discharge process uses a dual-CPU redundancy design, with the main CPU and vice-CPU working together to maximize test safety and reliability.
5. 7-inch true color touch display: 1024x800 resolution high-definition touch screen intuitively displays bar graphs, tables, graphs, data reports, and help documents. The touch panel uses a military-grade multi-layer composite film resistive panel, especially suitable for DC battery rooms and high-frequency charger electromagnetic interference and transient pulse interference.
6. Multiple test template presets: Built-in six commonly used test parameter templates. Template data is saved through power-down, eliminating the need to reset every time the machine is turned on. Start testing by powering on the machine — true one-button startup for simple, efficient testing.
7. Historical data curve view: Built-in data files can be queried in chart and waveform curve form, with zoom in, zoom out, left shift, right shift, and other multi-angle waveform displays.
8. Powerful data storage and backup: Built-in 16GB data storage space can store more than 1,000 groups of charge/discharge data, and supports historical data viewing, analysis, and deletion. With a 16G USB drive, data analysis and backup management are performed through PC host software.
9. Calibration function: The instrument is equipped with voltage and current calibration and correction functions to calibrate and correct measurement errors on site, ensuring measurement accuracy. This is especially suitable for consistency requirements between instrument readings and field instruments.
10. Multiple discharge test alarms: Configurable alarms include discharge capacity, discharge time, single-unit voltage threshold, and whole-group voltage threshold. The test automatically stops when any condition is met. Fault alarms include over-voltage, over-current, over-temperature, and reversed voltage test terminals.
11. Rich expansion interfaces: The back of the instrument provides multiple parallel, remote control, USB, and other communication interfaces.
12. Professional PC analysis and management software: Provides in-depth analysis of test data, single-voltage curves, whole-group voltage curves, whole-group current curves, single histograms, and real-time data forms. The host software includes password protection and experimental conclusions, and can automatically generate Excel or Word reports for printing and archiving.
