好的,为了确保安全,需要加入过压、过流和反向保护等电路设计。下面是一个简单的代码示例,可以根据实际情况进行修改:
```
#define VIN_PIN 34
#define BATTERY_PIN 35
#define SOLAR_PIN 36
float solar_voltage;
float battery_voltage;
float threshold_voltage = 12.0;
float max_voltage = 14.0;
float min_voltage = 10.0;
float charge_current = 0.5; // 0.5A
void setup() {
pinMode(VIN_PIN, OUTPUT);
pinMode(BATTERY_PIN, INPUT);
pinMode(SOLAR_PIN, INPUT);
}
void loop() {
// Read solar voltage
solar_voltage = analogRead(SOLAR_PIN) * (3.3 / 4096.0);
// Check if solar voltage is above threshold voltage
if (solar_voltage > threshold_voltage) {
// Calculate charge current based on battery voltage
battery_voltage = analogRead(BATTERY_PIN) * (3.3 / 4096.0);
charge_current = (max_voltage - battery_voltage) / (max_voltage - min_voltage);
charge_current = constrain(charge_current, 0.0, 1.0);
// Check for overcurrent and overvoltage
if (charge_current > 1.0) {
charge_current = 1.0;
} else if (battery_voltage > max_voltage) {
charge_current = 0.0;
}
// Set PWM duty cycle to control charging current
ledcSetup(0, 5000, 8);
ledcAttachPin(VIN_PIN, 0);
ledcWrite(0, charge_current * 255);
} else {
// Stop charging
ledcWrite(0, 0);
}
// Check for reverse voltage
if (digitalRead(VIN_PIN) == HIGH && digitalRead(BATTERY_PIN) == HIGH) {
digitalWrite(VIN_PIN, LOW);
digitalWrite(BATTERY_PIN, LOW);
}
delay(1000);
}
```
需要注意的是,以上代码只是一个基本的实现示例,具体实现还需要根据具体的电路设计和需求进行调整。同时,也需要根据具体的硬件设备和电路参数来设置阈值和限制条件。
