The ampere is an SI base unit and is not defined in terms of charge and time at the moment. There is a proposal that has been put forward (2005), though still not ratified (2014) that would indeed define an ampere in terms of charge and time. Since the second is a fundamental unit and an electron a fundamental particle it is proposed to define an ampere as the rate of flow of fundamental charges. It is equivalent to 1 coulomb of charge flowing for 1 second.
At the moment , the amp(ere) in fact, is defined in terms of the force between parallel, current-carrying, conductors. However, there is uncertainty in this measurement of a few parts in 10,000,000.
So, if you were to break down the ampere, you would find it currently is defined in terms of the metre (a base unit) and the newton (a derived unit) which, in turn, is defined in terms of the base units kilogram, metre, and second.

What are the 5 fundamental quantities?
Mass, length, time, temperature, and electric current.
What are the five example of fundamental quantities?
The five fundamental quantities are mass, length, time, electric current, and temperature. These quantities form the basis of the International System of Units (SI) and are used to define all other derived quantities.
How many basic fundamental quantities are there?
There are seven basic fundamental quantities in physics: length, time, mass, electric current, temperature, amount of substance, and luminous intensity.
What are the 8 basic fundamental quantities?
The eight basic fundamental quantities are length, mass, time, electric current, temperature, amount of substance, luminous intensity, and angle.
Why is the electric current a base quantity?
Electric current is considered a base quantity because it is an independent physical quantity that cannot be defined in terms of other fundamental quantities. It is a fundamental building block in physics and is used to define other electrical quantities such as voltage and resistance.
