add the code if battery at 50% discharge, will automated charges

copilot

To automate the charging of the battery at a 50% discharge level, you'll need a microcontroller that can monitor the battery's voltage and control the charging process. Let's assume you're integrating an ESP32-WROOM-32 microcontroller for this purpose.

Here's a basic idea of how the code would look like using Arduino IDE for the ESP32:

Cpp
#include 

const int batteryPin = 34; // Analog pin to measure battery voltage
const float maxVoltage = 4.2; // Maximum voltage for a fully charged 18650
const float minVoltage = 3.0; // Minimum safe voltage
const float dischargeThreshold = 3.6; // Voltage corresponding to ~50% discharge
const int chargerCtrlPin = 26; // Digital pin to enable/disable charger

void setup() {
  Serial.begin(115200);
  pinMode(chargerCtrlPin, OUTPUT);
  digitalWrite(chargerCtrlPin, LOW); // Start with charging off
}

void loop() {
  float batteryVoltage = getBatteryVoltage();
  Serial.println("Battery Voltage: " + String(batteryVoltage) + " V");

  if (batteryVoltage < dischargeThreshold) {
    startCharging();
  } else {
    stopCharging();
  }

  delay(60000); // Check every minute
}

float getBatteryVoltage() {
  int rawValue = analogRead(batteryPin);
  float voltage = rawValue * (maxVoltage / 4095.0); // Convert to voltage
  return voltage;
}

void startCharging() {
  digitalWrite(chargerCtrlPin, HIGH); // Activate charger
  Serial.println("Charging enabled");
}

void stopCharging() {
  digitalWrite(chargerCtrlPin, LOW); // Deactivate charger
  Serial.println("Charging disabled");
}

Components and Connections:

Battery Monitoring: Use a voltage divider to scale down the battery voltage to a range the ESP32 can measure (0-3.6V for safety).
Charger Control: Use a digital pin on the ESP32 to control the charge enable pin on the charger module.
ESP32 Analog Pin: Use an appropriate pin to read the scaled battery voltage.

Important Considerations:

Voltage Divider: Necessary to safely measure battery voltage without exceeding the ESP32's input limits.
Charger Module: Ensure the charger module has a controllable enable/disable pin.
Voltage Calibration: Calibrate the voltage reading depending on the actual resistors used in the voltage divider.

This is a simple automation setup where the ESP32 activates charging when the battery voltage drops to about 50%. You'll need to customize the voltage values and connections based on your specific hardware setup. Let me know if you need further details or clarification!

tinoaja07

Here's an updated block diagram including the ESP32-WROOM-32 microcontroller for monitoring battery voltage and controlling the charging process automatically. This setup will charge the battery when it discharges to approximately 50%.

Component Descriptions:

ESP32-WROOM-32:
- Functions: Monitors the battery voltage and controls the charger.
- Connections:
  - Connect the battery voltage (via a voltage divider) to an analog input on the ESP32 to read the battery level.
  - Use a digital output pin to control the charger module's enable/disable function.
Voltage Divider:
- Purpose: Scales down the battery voltage $3V$ to $4.2V$ to a safe level $0V$ to $\sim3.3V$ for the ESP32's analog input.
- Connections: Connects between the battery and an analog input on the ESP32.
18650 Battery:
- Function: Powers the system and is monitored for charge/discharge levels.
Battery Charger Module (e.g., TP4056):
- Control: Controlled by the ESP32 to start or stop charging based on the battery level.
12W DC Lamp & Switch:
- Function: The main light is manually operated by the switch.

Workflow:

Voltage Monitoring: The ESP32 continuously monitors the battery's voltage through the voltage divider.
Automated Charging: When the voltage drops to approximately $3.6V$ (50% discharge), the ESP32 activates the charger module.
Manual Lamp Control: The lamp is controlled through a manual switch connected in series with the battery.

The inclusion of the ESP32 enables an automated process for managing battery charge levels, ensuring that the battery is recharged when necessary without manual intervention.

Would you like more specific values for resistors or any other parameters for this setup? Let me know, and I can help further refine the schematic!

tinoaja07

what specific values for resistors?

copilot

For the voltage divider that interfaces with the ESP32, we'll calculate specific resistor values. The goal is to safely scale the battery voltage (3V to 4.2V) down to a range that the ESP32's analog input can handle (0V to ~3.3V).

Voltage Divider

Formula for Voltage Divider: $ V_{\text{out}} = V_{\text{in}} \times \frac{R4}{R3 + R4} $

Assuming:

Maximum Battery Voltage is 4.2V.
ESP32's maximum ADC reference voltage is approximately 3.3V.
Let's select $ R4 = 10k , \Omega $ as a commonly used value.

Calculation for $ R3 $

Rearrange the formula to calculate $ R3 $:

4.2V \times \frac{R4}{R3 + R4} = 3.3V

R3 = \frac{4.2V \times R4}{3.3V} - R4

Now substitute $ R4 = 10k , \Omega $ and solve for $ R3 $:

R3 = \frac{4.2V \times 10k \, \Omega}{3.3V} - 10k \, \Omega

Let's calculate this value:

Code Interpreter

Python
# Constants for calculation
R4 = 10000  # in Ohms
Vin_max = 4.2  # in Volts
Vout_max = 3.3  # in Volts

# Calculate R3
R3 = (Vin_max * R4 / Vout_max) - R4
R3

The calculated value for $ R3 $ is approximately $ 2.73k , \Omega $.

Recommended Resistor Values:

$ R3 = 2.7k , \Omega$ (a standard resistor value)
$ R4 = 10k , \Omega$

These values should safely scale your battery voltage to an appropriate level for the ESP32's ADC input. Adjust these values if you're using a different ADC reference voltage. Let me know if you have more questions or need further assistance!

Project Name

USB LED Lamp Circuit

Description

Here is a simple USB powered lamp that can be used to light your desktop during power failures. The circuit operates from the 5 Volt available from the USB port. The 5V from the USB port is passed through current limiting resistor R2 and transistor Q1. The base of transistor Q1 is grounded via R1 which provides a constant bias voltage for Q1 together with D2. The diode D1 prevents the reverse flow of current from battery. C1 is used as a noise filter. Two white LED’s are used here for the lamp, you can also use a 2 V torch bulb instead of LED’s. LED D3 indicates connection with USB port.
