When you plug an AC adapter into a wall outlet, it converts the alternating current (AC) into direct current (DC), which is what your battery needs to be charged. Yes, you can use a switching power supply to charge a battery. The process is simple and easy to follow.
Say half an hour, then 24 V 24+ A supply. Replacing a battery from a battery-operated equipment with a power supply can be tricky. Especially when the equipment uses an electric motor. The problem is that an electric motor can draw very large startup current - it can be as 10-20 times the nominal for a couple of seconds.
This kind of connector can be used to switch the device from running on the battery pack to running on the power supply whenever the it is plugged in. To wire up this jack to the rest of the circuit, cut the wire coming from the positive terminal of the battery pack in half.
If I replace my batteries with a power supply of equal voltage, then the current in the system also stays the same. This project uses this relationship to replace Voltage, V supplied by a battery with voltage supplied by a DC power supply – nothing else is changed.
This toy just sits on the desk, so it’s a good candidate to modify to accept a DC power supply instead of batteries. This idea is not well suited to something like an R.C. Car, but in a pinch, you can use it on the remote control for your TV. Wall outlet power is generally alternating current, or ‘AC’.
It converts an AC input voltage into a DC output voltage. The DC output voltage can be regulated to be either higher or lower than the AC input voltage. A switching power supply can be used to charge a battery. Once the battery is fully charged, disconnect it from the power supply and store it in a safe location.
Using a Switching Power Supply for Battery Charging
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling. The ...

What Is a Power Supply & How Does It Work? | ACT
Most electronics require regulated power. When a power supply changes the voltage and type of power, the result is not always a steady output. Though it does not turn on and off completely, fluctuations in the outcoming voltage still occur without regulation. An unregulated power supply can deliver more power than expected. Such a surge fed to ...

Automatic switching between two power sources
Hi I have a project which gets its power from a car battery or a 12V wall wart. What I''d like to do is have both of these wired in, but when the mains power is present, have the battery no longer supplying. The battery and the mains supply are going to be kept independent, so no charging occurs, and I''d like to make it automatic so the battery can kick in almost as a …
