How do I choose right battery for my electric vehicle? Not the type one but rather the capacity of the battery(e.g 120V 70Ah) And how to calculate the range from that battery?
Hi, Basara -
Well...simple enough question, but not so simple answer!
Why? Because the more AH, the more range you'll have - but the heavier and more expensive the batteries will be.
So. Your mission is to decide at what point the benefits outweigh the added cost and weight. Most of the time people take the highest AH battery they can afford - they make batteries up to 200 AH or so. I don't think I'd go any lighter than 100 AH, or you'll be charging it all the time; )
There are various range calculators here there and everywhere - it depends on your electric car setup. This EV Calculator seems pretty good to me.
Hope this helps, and good luck with your EV project!
