Darui Electric recommends for you Product Introduction: The intelligent charging/discharging tester is a product launched to meet market demands, integrating five functions: charging, discharging, single cell detection, online monitoring, and activation. It features high integration and more comprehensive functions. By conducting capacity tests on batteries, it can accurately and quickly identify weak batteries and provide the remaining capacity of each individual cell. Through activation, each cell in the battery pack can quickly and fully increase its capacity, reduce internal resistance, and effectively resolve voltage imbalance among cells. Features and Functions: ● Display: Large LCD screen display, Chinese menu prompts, real-time display of all test data: total battery voltage, individual cell voltage, current, capacity, duration, and internal temperature. ● Control: Microcontroller control, set parameters such as equalizing charge voltage, float charge voltage, discharge termination voltage, charge/discharge current, duration, and capacity via keyboard. ● Real-time online巡回检测 of each individual cell parameter, automatically complete various parameter testing and monitoring of the battery pack. ● Quickly and accurately identify failed and weak batteries in the battery pack through rapid discharge in a short time, estimate remaining battery capacity, and evaluate battery quality. ● Working Modes: (1) Constant current discharge mode automatically completes battery capacity test or load capability test, can estimate remaining battery capacity through a five-minute rapid discharge for capacity analysis. (2) Intelligent three-stage charging mode: initial stage uses constant current technology, constant charging current, quickly raises battery voltage; when charging voltage reaches the upper limit, automatically switches to constant voltage and decreasing current charging, effectively improving battery capacity conversion efficiency; final stage switches to trickle float charging, ensuring each cell receives balanced charge, maximizing capacity recovery, effectively resolving voltage imbalance, and avoiding overvoltage charging risks. (3) Cyclic charge/discharge function: set charge/discharge hour rate and voltage high/low limits, automatically cycle through one discharge and one charge process. (4) Battery activation function: set charge/discharge cycle count, use pulse charging to activate and repair batteries. ● Automatic Shutdown: Automatically stops when any of the following conditions are met: time reached, capacity reached, individual cell protection voltage reached, total pack protection voltage reached, cycle count reached, etc. ● Automatic Alarm: Features intelligent reverse connection protection; automatically alarms when high temperature, battery pack disconnection, undervoltage, overvoltage, overcurrent, etc. occur. ● Real-time Monitoring: Real-time display and control of all set parameters (such as total battery voltage, individual cell voltage, current, capacity, duration, and internal temperature). ● Record Query: The charge/discharge tester can store 16 sets of charge/discharge data, users can query as needed. ● Data Transfer: Equipped with standard USB and RS232 interfaces. After charging, data can be transferred via USB flash drive or directly uploaded to a computer via RS232 interface, solving large-capacity data storage issues. ● Data Processing: Charge/discharge data can be analyzed and processed by the accompanying data processing software to automatically generate various curves and charts, supporting printing. ● Computer Remote Control: Charge/discharge parameters can be set and modified via computer; control the start/stop of charging/discharging of the tester. ● Voltage and Current Calibration: Calibration and correction of total battery pack voltage, individual cell voltage, and current. ● Power components use special alloy resistors, produced with independent intellectual property patent technology, high power density, no open flame, safe and reliable, long lifespan. ● Modular design, high automation, easy operation, high charging recovery rate, energy-saving, and other notable features. Compact size, easy to carry, forced air cooling. Data Processing Software Directly obtain charge/discharge information from the tester; after processing and analysis, generate current curve, voltage curve, individual cell curve, capacity analysis chart, individual cell bar chart, and characteristic comparison chart. |
