Product Introduction:
The intelligent charge/discharge detector is a five-in-one product launched to meet market demands, integrating charging, discharging, cell monitoring, online monitoring, and activation functions, with a high degree of integration and more complete functionality. 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 enhance its capacity, reduce internal resistance, and effectively solve the problem of voltage imbalance among cells.
Features and Functions:
● Display: Large LCD screen display with Chinese menu prompts, real-time display of all test data: battery pack voltage, individual cell voltage, current, capacity, duration, and internal temperature.
● Control: Microcontroller-based control, with parameters such as equalizing charge voltage, float charge voltage, discharge termination voltage, charge/discharge current, duration, and capacity set via keyboard.
● Real-time online巡回检测 of each cell parameter, automatically completing testing and monitoring of various battery pack parameters.
● Quickly and accurately identify failed and weak cells in the battery pack through rapid discharge within a short time, estimate remaining capacity, and evaluate battery quality.
● Working modes: (1) Constant current discharge mode automatically completes battery capacity testing or load capability testing, and can estimate remaining capacity through a five-minute rapid discharge for capacity analysis. (2) Intelligent three-stage charging mode: initial stage uses constant current technology to maintain a constant charging current, rapidly raising battery voltage; when the charging voltage reaches the upper limit, it automatically converts to constant voltage with reduced current charging, effectively improving the capacity conversion efficiency of the battery; at the end of charging, it switches to trickle float charging to ensure balanced charging of all cells, maximizing capacity recovery, effectively solving voltage imbalance, and avoiding the danger of overvoltage charging. (3) Cyclic discharge/charge function: set the discharge/charge hourly rate and voltage high/low limits, automatically cycle through one discharge and charge process. (4) Battery activation function: set the number of charge/discharge cycles, use pulse charging to activate and repair the battery.
● Automatic shutdown: Automatically stops when any of the following conditions is met: time reached, capacity reached, cell protection voltage reached, pack protection voltage reached, cycle count reached, etc.
● Automatic alarm: Has intelligent reverse connection protection, and automatically alarms in cases of high temperature, battery pack disconnection, undervoltage, overvoltage, overcurrent, etc.
● Real-time monitoring: Real-time display and control of set parameters (such as battery pack voltage, individual cell voltage, current, capacity, duration, and internal temperature).
● Record query: The charge/discharge detector can store 16 sets of charge/discharge data, which users can query as needed.
● Data transfer: Equipped with standard USB and RS232 interfaces. After charging, data can be transferred via U盘 or directly uploaded to a computer through the RS232 interface, solving the problem of large-capacity data storage.
● Data processing: The charge/discharge data can be analyzed and processed by the accompanying data processing software to automatically generate various curve charts and support printing.
● Computer remote control: Parameters for charging/discharging can be set and modified via computer; the charge/discharge detector can be started or stopped remotely.
● Calibration and correction of voltage and current display values: Allows calibration and correction of total battery pack voltage, individual cell voltage, and current.
● Power dissipation components use specially made alloy resistors, produced with proprietary patented technology, featuring high power density, no open flame, safe and reliable, and long lifespan.
● Modular design, high automation, easy operation, high charging recovery rate, energy-saving, and other notable features. Compact and portable, with forced air cooling.
Data Processing Software
Directly obtains charge/discharge information from the charge/discharge detector, and after processing and analysis, can generate current curve charts, voltage curve charts, cell curve charts, capacity analysis charts, cell bar charts, and characteristic comparison charts.
