Battery Charger Discharger Board
Specifications:
- Power supply voltage: DC 6-40V
- Voltage detection range: DC 0-60V
- Suitable for batteries under 60V
- Voltage measurement error: ± 0.1V
- Charge and discharge time (OP) range: 0 - 999 minutes
Features:
- Intelligent control of battery charge and discharge
- Settable charge and discharge time
- Real-time monitoring via serial communication
- Additional high signal output for equipment control
- Emergency stop button (STOP) with reverse protection
Operating Modes:
- U-1: Charging Measurement: Relay engages when voltage drops below lower limit; disengages at upper limit.
- U-2: Charge Time Control: Set charge time (OP). Relay engages below lower limit, starts countdown, disengages when time ends or when upper limit is exceeded.
- U-3: Discharge Detection: Relay disengages below lower limit; engages above upper limit.
- U-4: Discharge Time Control: Set discharge time (OP). Relay engages above upper limit, starts countdown, disengages when time ends or when lower limit is exceeded.
- U-5: Voltage In Range: Relay engages when voltage is between limits; otherwise disengages.
- U-6: Voltage Out of Range: Relay engages when voltage is below lower or above upper limit; otherwise disengages.
Parameter Setting Guide:
- Decide the desired working model.
- On the main interface, hold the SET button for 2 seconds to enter mode selection, use UP/DOWN to select mode (U-1 to U-6).
- Select the mode and press SET to adjust parameters. Use UP/DOWN to modify values and SET to move to the next parameter.
- Hold SET for 2 seconds to save settings and return to the main interface.
- Use the DOWN key to switch between voltage and time displays.
Additional Features:
- Data upload every second for post-analysis
- Settings can be adjusted through serial port
- Additional signal output for condition met relay
Serial Port Control (TTL Level Communication):
- Baud rate: 115200 bps
- Data bits: 8
- Stop bit: 1
- No check digit or flow control
Serial Commands:
- "U-1": Set operating mode (range U-1 to U-6)
- "000": Disable timing, non-0 enables (001 to 999)
- "Dw02.9": Set lower limit voltage
- "Up10.1": Set upper limit voltage (00.0V ~ 99.9V)
- "Get": Get current settings
- "On": Turn relay on
- "Off": Turn relay off
- "Start": Begin data upload
- "Stop": End data upload
Commands can be combined, separated by commas (e.g., "dw02.9, up10.1").
STOP Key Function Expansion:
Relay Enable Mode:
- ON: Relay conducts during OP time
- OFF: Relay is disabled and remains off
- Use STOP button to switch between ON/OFF. Current status flashes and returns to main interface.
Sleep Mode:
- C-P Sleep Mode: Auto shut down display after 5 minutes inactivity, program runs normally.
- O-d Normal Mode: Display remains on.
- Hold STOP for 2 seconds to toggle between modes. Current state flashes and returns to the main interface.
Package Includes:
- 1 × Battery Charger Discharger Board
