6 FAQs about [Direct power supply switching between battery and power supply]
How does a DC power supply work?
With mains present, the DC supply will maintain/charge the battery and power connected peripherals at the same time. You need to regulate the DC supply output voltage to match the battery maintenance-charge level (about 13.7V). At this level, you can leave it connected/powered at all times. Switchover is instant as this is a hot standby connection.
Can I use a power supply with a higher voltage?
You could use a power supply with a higher voltage than the battery, both the battery and the power supply have their own diode feeding the Arduino. As long as the mains are good the higher voltage will block the current from the battery. When the mains fail the battery will have a higher voltage and provide power through its diode.
Can a portable equipment operate from a battery pack or external power source?
Portable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit (Figure 1) that switches power sources with good efficiency and without switching noise. Figure 1.
How can I use a line-powered switching power supply instead of a battery?
simulate this circuit – Schematic created using CircuitLab If you always want to use the line-powered switching power supply in preference to the solar-charged battery, then arrange that power supply to put out a little higher voltage than the battery. It doesn't need to be much, even just a few 100 mV would do it.
How do I connect a battery to a power supply?
In the past the simple solution was to use a DC power connector with a built in physical switch such as this one from Lumberg. When the DC plug is inserted it breaks the power from the battery to the circuitry so the power then comes from the external DC power source.
How do you charge a battery with a Schottky diode?
Another possibility is to connect the battery directly, and the power supply thru a Schottky diode. Arrange the power supply voltage to be the battery float charge voltage after the diode. You can think of the battery as always providing the power, and the power supply charging the battery when on.
