...That's not how chargers work. That's how power supplies for computers work. They are similar, but not the same.At 120 V 12 Amps the circuitry is very lightly loaded and...
The charger is in modules, each module is set for a certain pwer draw. To access a different power level, it turns on or off charging modules to reach the value.
It is not like a computer or bench power supply because the voltage needs to be matched to the battery pack. A battery is not just a standard load which lowers the voltage on the battery supply and the rectifier needs to compensate. it's not just a load, but a delicate voltage level slightly higher than the battery's which much be maintained. Like having two reservoirs with a siphon, they need to be balanced lest they overflow (and make the battery go boom).
No, the chargers only run at different efficiencies based upon the voltage in the battery pack. Not how many charging modules (total charging rate) that it is running at.
