Battery Charger Discharger Board Description

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:

  1. Decide the desired working model.
  2. 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).
  3. Select the mode and press SET to adjust parameters. Use UP/DOWN to modify values and SET to move to the next parameter.
  4. Hold SET for 2 seconds to save settings and return to the main interface.
  5. 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
