Battery Charge Discharge Controller with Integrated Voltmeter and Protection Features

Key Highlights:

1. Intelligent Battery Charge and Discharge Control:
   • Automatically manages charging and discharging processes.
2. Customizable Charge and Discharge Timing:
   • Set specific time intervals for charging and discharging operations.
3. Serial Communication Capability:
   • Real-time monitoring of relay working status via serial port.
4. Additional Signal Output:
   • High output when relay conditions are met, enabling control of external equipment.
5. Emergency Stop Function:
   • One-touch STOP button with reverse polarity protection to prevent damage.

Operating Modes:

• Voltage Upper Limit (UL1) and Lower Limit (nL1) must satisfy: UL1 > nL1.

1. U-1: Charging Measurement
   • Relay activates when voltage is below nL1.
   • Relay deactivates when voltage exceeds UL1.
2. U-2: Charging with Time Control
   • Set charging duration (OP).
   • Relay activates below nL1 and deactivates after OP timer ends or when UL1 is exceeded.
3. U-3: Discharge Detection
   • Relay deactivates below nL1 and activates above UL1.
4. U-4: Discharge with Time Control
   • Set discharge duration (OP).
   • Relay activates above UL1 and deactivates after OP timer ends or when nL1 is reached.
5. U-5: Voltage Range Activation
   • Relay activates when voltage is within UL1 and nL1.
6. U-6: Voltage Out-of-Range Activation
   • Relay activates when voltage is either below nL1 or above UL1.

Product Parameters:

1. Power Supply Voltage: DC 6–40V
   Voltage Detection Range: DC 0–60V
   Measurement Error: ±0.1V
2. Charge/Discharge Time (OP) Range: 0–999 minutes

Setting Parameters:

1. Determine the Work Mode:
   • Default mode: U-1.
   • To select a different mode, press the SET button for 2 seconds in the main interface, then use UP/DOWN buttons.
2. Adjust Parameters:
   • Press SET to edit parameters like UL1, nL1, and OP.
   • Use UP/DOWN to increase or decrease values.
   • Confirm settings by pressing SET for 2 seconds.
3. Main Interface Controls:
   • Press DOWN to toggle between voltage and time displays.

Additional Features:

1. Data Upload:
   • Send voltage and runtime data every second via serial port for analysis.
2. Serial Port Parameter Settings:
   • Configure mode and parameters via serial port.
3. Extra Signal Output:
   • High output when relay conditions are met; low output otherwise.

Serial Port Communication:

• Standard Settings:
  • Baud Rate: 115200 bps
  • Data Bits: 8
  • Stop Bit: 1
  • Parity: None
  • Flow Control: None
• Commands:
  • “U-1”: Select mode (U-1 to U-6).
  • “000”: Disable timing; non-zero (001–999) enables timing.
  • “Dw02.9”: Set lower limit voltage.
  • “Up10.1”: Set upper limit voltage (0.0–99.9V).
  • “Get”: Retrieve current settings.
  • “On”: Enable relay.
  • “Off”: Disable relay.
  • “Start”: Start data upload.
  • “Stop”: Stop data upload.

  Example Command: “dw02.9, up10.1” sets lower limit to 2.9V and upper limit to 10.1V.

• Upload Format:
  • “Voltage, Time, Status”
  • Example: “00.0V, 00:00:00, OPr\n”

STOP Key Functions:

1. Relay Enable/Disable:
   • ON: Enables relay during OP conduction time.
   • OFF: Disables relay (always off).
   • Toggle status by pressing STOP in the main interface.
2. Sleep Mode:
   • C-P: Sleep after 5 minutes of inactivity (display off, operation normal).
   • O-d: Display always active.
   • Switch modes by holding STOP for 2 seconds.

This comprehensive Battery Charge Discharge Controller offers robust charge and discharge management with advanced customization and monitoring capabilities, making it ideal for a variety of battery-operated systems.
