Hi Alex,
  	This is a good start but we need a bit more information.  

	Making a vehicle go 100 kph is fairly easy, making one that can go
150 kph is a little bit harder.  Exactly what kind of vehicle are you
talking about?  Is it a normal car converted to electric and if so what
kind?  Are you going to build the car?  If so describe it, is it a small
sports car or a large pickup or ... ?

	How much range do you want?  Going 100 kph for 100 km in a pickup
can be done, but it requires a LOT of batteries maybe 700Kg or more.  Doing
it in a sports car requires less batteries, but you have less room for them.
	Going 150 kph for 100 km is REALLY tough, it takes a lot of money to
make that work.
	My pickup carries 430Kg of batteries and is fairly small and
lightweight, only 1450Kg total.  At 100 kph it has a range of perhaps 50 km
(on a warm day, much less when it's cold).

	What type of motor you need depends on the vehicle's aerodynamic
drag and how heavy it is.  Also important is whether or not you need to
climb hills or just run on flat ground.  Even very slight hills can double
the amount of power the motor requires.

	Your English is fine, don't worry about it.
