Battery Charge/Discharge TesterDarui Electric recommendsProduct Introduction:Intelligent charge/discharge tester is a product launched to meet market demand, integrating charging, discharging, single cell monitoring, online testing, and activation into one. It features high integration and 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 capacity, reduce internal resistance, and effectively solve the problem of 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, time, and internal temperature.
● Control: Microcontroller control, set parameters such as equalizing charge voltage, float charge voltage, discharge termination voltage, charge/discharge current, time, and capacity via keyboard.
● Real-time online巡回检测 each individual cell parameter, automatically complete testing and monitoring of various parameters 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 capacity test, can estimate remaining battery capacity through a five-minute rapid discharge for capacity analysis. (2) Intelligent three-stage charging mode: uses constant current technology at the initial stage, with constant charging current to quickly raise battery voltage; automatically switches to constant voltage and decreasing current charging when the voltage reaches the upper limit, effectively improving battery capacity conversion efficiency; at the end of charging, switches to trickle float charging to ensure balanced charging of each cell, maximize battery capacity recovery, effectively solve voltage imbalance, and avoid overvoltage charging hazards. (3) Cycle 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 times, 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: Intelligent reverse connection protection, automatically alarms when high temperature, battery pack connection disconnection, undervoltage, overvoltage, overcurrent, etc. occur.
● Real-time monitoring: Real-time display and control of set parameters (such as total battery voltage, individual cell voltage, current, capacity, time, and internal temperature).
● Record query: The charge/discharge tester can store 16 sets of charge/discharge data, which can be queried as needed.
● Data transfer: Standard USB interface and RS232 interface. After charging, data can be transferred via U disk or directly uploaded to 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: Set and modify charge/discharge parameters via computer; control start/stop of charge/discharge tester.
● Voltage and current display calibration: Calibrate and correct total battery voltage, individual cell voltage, and current.
● Power consumption components use special alloy resistors, produced with independent intellectual property patent technology, high power density, no open flame, safe and reliable, long life.
● Modular design, high automation, easy operation, high charge recovery rate, energy-saving, etc. Compact size, easy to carry, forced air cooling.
Data Processing SoftwareDirectly obtain charge/discharge information from the charge/discharge tester, after processing and analysis, can generate current curve, voltage curve, individual cell curve, capacity analysis chart, individual cell bar chart, and characteristic comparison chart.
