250 kw is about 335 hp if I am not mistaken, Which after a little more research into motors may be somewhat more than I need.
I think you just about have my idea pegged! I'm not exactly trying to build a Tesla, but something similar to it where i have all the control over the design. I have been thinking about my requirements and two things come to mind. Range being the first. I live in Austin, TX and would like to have the ability to travel to some of the major cities on a single charge. That being said 250 to 300 miles would be ideal. Secondly i would like a good deal of power to be able to get up and go. I do a considerable amount of interstate driving, so being able to get up and around people would be nice if needed. I assume that the 250 kw that i stated would be peak power, only used when say going uphill or to pass someone. I will have to figure out specific figures later, but are electric motors rated by their peak power? I read the amount of kw produced depends on your controller and if your motor and batteries can handle the load. I think i need to buy a book and do more research on this matter as I feel so lost! Any suggestions?
