Modular Design (Some High-end/High-power Models): Power scalability achieved by paralleling modules for flexibility.
Product Function
Constant Current Charge and Discharge: It performs constant current discharge at a set value by continuously regulating the discharge current, using the battery as the discharge load in offline mode. It also supports charging with adjustable voltage and current.
Automatic Test Termination: The Battery Charge and Discharge Tester manufacturer automatically stops discharging when the battery terminal voltage or individual cell voltage falls to the set lower limit, or when the set discharge time or capacity is reached.
Wireless Cell Voltage Monitoring: It features wireless relay access for single battery voltage monitoring, with each wireless monitoring module capable of monitoring up to 12 individual cells simultaneously, ensuring simple, safe, and accurate data collection.
Comprehensive Protection: It includes perfect protection functions with audible and visual alarms, clear interface prompts, and PTC ceramic resistors to avoid red-hot phenomena, making the entire discharge process safer.
Data Management: The discharge process data is stored in the device's memory and can be archived to a USB drive via the data interface. The upper computer software analyzes data and generates required curves and reports.
Wide Voltage Range: It features a 10–600V wide voltage design, with a single machine capable of meeting charge and discharge test requirements for various voltage grade battery packs.

Frequently Asked Questions
|
Q: Why is battery charge-discharge testing necessary? A: Through testing, it is possible to: Determine whether the actual battery capacity meets the specified standards Identify batteries with capacity degradation Prevent backup power failures in advance Extend battery service life Improve the reliability of the power supply system |
|
Q: Can the battery charge-discharge tester determine whether a battery needs to be replaced? A: Yes. Through capacity testing, discharge curve analysis, and performance data evaluation, it can determine whether the battery has experienced capacity degradation, aging, or performance abnormalities, thereby assisting in the decision of whether replacement is necessary. |
|
Q: Why is a battery charge-discharge tester needed in substations? A: The DC system in substations relies on batteries to provide backup power. Through charge-discharge testing, it can be confirmed whether the battery bank has the reliable power supply capability required during power outages or emergency situations. |
