They're charged with power, which is current x voltage. If you have infinite current and zero voltage or vice versa, nothing happens.

The normal power source for capacitor charging is a constant current source, one in which the voltage follows the desired current. The least desirable source is a constant-voltage supply, which (in the ideal case) will deliver infinite current at time zero. The voltage on a capacitor is the time integral of past applied currents. The ideal charging scheme is a constant current source, which cuts off as the capacitor's voltage limit is reached. Sorry for the late reply, I am traveling.
