hi everyone, I've been thinking of converting a car to ev since 2014 and recently i decided to go through with it ,
Previously i had some unrealistic goals but now i reevaluated things and here is what i came up :
i will use a bmw e46 coupe or a volvo s60 mk1
range of 80-100 miles
capable of doing 80 mph
decent acceleration something like 8-9s 0-60
i will use a 13'' dc motor from a forklift
the donor car must be manual as ill use the original transision
ill make my battery pack out of 18650 cells , already got 2k cells(still buying them, i know i need more

)
i am pretty good with tools so i will do most of the work myself
budget as little as possible,
I know that i need something like 30kwh battery pack to achieve my starting range.
i know that i need a charger

i know that i need a motor controler
i don't know how to build them or where to get them from
What voltage my battery has to be, and is there a way to diy the motor controller and the charger, do i need motor cooling ,do i need battery heating?
i really want to learn this and buid myself and understand it, because when its done and something broke on it can't just roll in the first garage and ask them to fix it....
so please if you can shed some light on my build or have any sugestion let me know please
i also plan to keep extending the battery pack until i reach the limit that the car can hold,so the range will keep growing , 80 miles is the starting range .
Please dont try to suggest to chose a little car or something light etc as i do 40-60 miles a day in it and also put a large chunk of money into it so it will be one of the above state cars.
thank you
