It's not your English - it's your question. But welcome to the worldwide
community of electric vehicle enthusiasts.

You will need to work out what the intended use for the vehicle will be,
who will be the user, who will do the maintenance.

You are in the right place to get answers for almost anything associated
with conversion, repair, maintenance of an EV.

Number one thing to determine: how far and how fast does this car need to
go, with how many occupants. Also what is the budget and who will be using
the vehicle? This will determine a lot of the basic parameters for the
vehicle. Determine this and a lot of the other decisions will be forced on
you. You cannot build a 'perfect' vehicle for all situations, so you need
to work out what you need to do, then fit to this.

If the car is to be used by a non-technical person, far more will be needed
in design to make it as 'normal' and as foolproof as possible. Good parts
and systems will need to be used, with simple (to the operator) indicators
for what is happening. If a non-technical person is using the vehicle, an
AC system is probably necessary, since most (but not all) failure modes for
an AC system will stop the vehicle, where a DC system will all too often
fail at full power, needing the user to hit an emergency stop. 

So you see, the AC or DC question is not the first thing to ask.
