Is Planck Charge Related to the Fine-Structure Constant and Plank's Constant?

Has an entity in the universe ever existed with a charge magnitude of 1.87755e-18 C (planck charge)? When/where could it arise?

It seems to be a key part of the electric and magnetic constants.. Wouldn't this imply that the Planck charge exists somewhere?

This is old, but it's kind of sad no one ever answered it, so I'm going to.

No, nothing (known) can have this charge. All known particles have integer multiples of e/3 as their charge (where e is the elementary charge-the magnitude of proton or electron charge). This is not such a multiple.

A layman think that Plank charge is intrinsicaly conected with alpha constant.
Coulomb law show the intaraction of two electric charges in the linear maner: E = e^2 /r.
Here the electric charge is e = 4 08032041 *10^-10 cm^3/2 g^1/2 sec.In this caseobserver is upon one of charges, which in this case are relative static.
Let supose that particles move toward each other in circle with radius r. In this case observer is considered in the centre of circuit. In this case E = e^2 / 2pi *r ecetr. In this case Planc constant is h/2*pi.
Now let supose that charges are moving in traectore in a sphere with radius r. In this case
the trajectore will be 2*pi* alpha. And plank constant must be h / 2*pi*alpha.
So the amount of electric charge is the same. In this case observer is out of sphere.
The Plank charge is e * alpha
