It serves more than one function, it controls the charging, discharge shut-off, cell balance charging and even lets the power supply know to stop outputting, if it's electronic.
In most cases, there will only be 2 pins/wires used for charging from the charger itself.
Any power supply will work as long as the voltage is a little higher than the pack outputs, as has already been mentioned by someone else and is regulated.
