Arduino MKR GSM 1400 (bq24195)

I'm trying to use the bq24195 to power on the charging when the battery is not full and turn it off when it's full.

void PMICSetup() {
    while (!PMIC.begin()) {
      // DEBUG_PRINTLN is just a serial print macro
      DEBUG_PRINTLN(10, F("CAN'T TURN ON CHARGER"));
    }

    PMIC.setInputCurrentLimit(5.0);  // 2
    PMIC.setInputVoltageLimit(3.88); // 3.88
    PMIC.setMinimumSystemVoltage(3.5);
    PMIC.setChargeVoltage(4.1);
    PMIC.setChargeCurrent(0.375);
    PMIC.disableCharge();
}

void CheckBattery(){

    while (true) {

      DEBUG_PRINTLN(200, F("Checking battery."));

      int batteryLevel = analogRead(ADC_BATTERY);
      float voltage = batteryLevel * (BATTERY_CAPACITY / 1023.0) * 0.9796523;

      if (PMIC.chargeStatus() == 0) {
        PMIC.enableCharge();
        DEBUG_PRINTLN(200, F("Enabling charging."));
      }

      if (PMIC.isBatteryInOverVoltage()) {
        PMIC.disableCharge();
        DEBUG_PRINTLN(200, F("Disabling charging."));
      }

      else if (PMIC.hasBatteryTemperatureFault()) {
        PMIC.disableCharge();
        DEBUG_PRINTLN(200, F("Battery too hot, disabling charging."));
      }

      else if (PMIC.chargeStatus() == CHARGE_TERMINATION_DONE) {
        PMIC.disableCharge();
        DEBUG_PRINTLN(200, F(" Battery fully charged."));
      }

      float battery_percentage = ((voltage * 100) / 4.2);
    }
}

The problem I have is that the battery doesn't seem to get turned on, it always prints "Battery fully charged". Do I have some error in my logic? the CheckBattery function is run in a loop and it's checked every 60s.

Incomplete code, that doesn't compile. We don't even have a clue what library you're using or how you wired your hardware.
