The Chargeur intelligent de batterie Li-ion 54.6V 5A, 48V (Manufacturer: WATE-300W, Part ID: Battery 48V 13s) is a high-performance battery charger designed for 48V lithium-ion battery packs. It is specifically tailored for 13-series (13s) Li-ion battery configurations, providing a maximum output voltage of 54.6V and a charging current of 5A. This charger incorporates intelligent charging algorithms to ensure safe, efficient, and reliable charging while extending battery life.

• Electric bicycles (e-bikes) and scooters
• Energy storage systems (ESS)
• Solar power systems with Li-ion battery banks
• Uninterruptible power supplies (UPS)
• Robotics and industrial equipment

The charger has a simple interface with the following connectors:

1. Connect the Charger to the Battery:

   • Ensure the battery pack is a 13-series (13s) Li-ion configuration with a nominal voltage of 48V.
   • Connect the charger's DC output terminals to the battery pack, ensuring correct polarity (Positive to Positive, Negative to Negative).

2. Power On the Charger:

   • Plug the AC input cable into a standard wall outlet (100-240V AC).
   • The LED indicator will light up red, indicating that charging has started.

3. Monitor the Charging Process:

   • The charger will operate in CC (Constant Current) mode initially, delivering 5A to the battery.
   • As the battery approaches full charge, the charger will switch to CV (Constant Voltage) mode, reducing the current gradually.
   • When the LED turns green, the battery is fully charged.

4. Disconnect the Charger:

   • Unplug the charger from the wall outlet before disconnecting it from the battery.

• Battery Compatibility: Only use this charger with 13s Li-ion battery packs. Using it with incompatible batteries may result in damage or safety hazards.
• Ventilation: Ensure adequate ventilation around the charger during operation to prevent overheating.
• Polarity Check: Always verify the polarity of the connections before powering on the charger.
• Storage: Store the charger in a cool, dry place when not in use.

While this charger is not directly connected to an Arduino, you can monitor the charging process using an Arduino and a voltage sensor. Below is an example code snippet to read the battery voltage:

// Arduino code to monitor battery voltage during charging
const int voltagePin = A0; // Analog pin connected to voltage sensor
const float voltageDividerRatio = 11.0; // Adjust based on your voltage divider

void setup() {
  Serial.begin(9600); // Initialize serial communication
  pinMode(voltagePin, INPUT); // Set voltage pin as input
}

void loop() {
  int sensorValue = analogRead(voltagePin); // Read analog value
  float batteryVoltage = (sensorValue * 5.0 / 1023.0) * voltageDividerRatio;
  
  // Print the battery voltage to the Serial Monitor
  Serial.print("Battery Voltage: ");
  Serial.print(batteryVoltage);
  Serial.println(" V");
  
  delay(1000); // Wait for 1 second before the next reading
}

Note: Use a voltage divider circuit to step down the battery voltage to a safe range for the Arduino's analog input (0-5V).

1. Charger LED Does Not Turn On:

   • Cause: No power supply or faulty AC input connection.
   • Solution: Check the wall outlet and ensure the AC input cable is securely connected.

2. LED Flashes Red:

   • Cause: Fault detected (e.g., overvoltage, short-circuit, or overheating).
   • Solution: Disconnect the charger and inspect the battery connections. Allow the charger to cool down if overheating is suspected.

3. Battery Does Not Charge Fully:

   • Cause: Battery capacity mismatch or degraded battery cells.
   • Solution: Verify the battery's capacity and health. Ensure it is a 13s Li-ion pack.

4. Charger Overheats:

   • Cause: Poor ventilation or high ambient temperature.
   • Solution: Operate the charger in a well-ventilated area and avoid using it in extreme temperatures.

• Always check the battery pack's specifications to ensure compatibility with the charger.
• Use a multimeter to verify the output voltage and current of the charger if issues persist.
• If the charger fails to operate after troubleshooting, contact the manufacturer or authorized service center for assistance.
