I would not even attempt to run a vehicle as large as a Caravan with only 48V. When you step into heavy-weight vehicles, you need heavy-weight components. I would consider 300V to be the minimum voltage, and I would prefer to run at 700V+. At that level, 200A is good for ~180hp. And electric HP at that.
As for un-sprung weight, I'll say it again, I don't think that many people understand just how much weight there is there already, and can be done away with. The entire un-sprung assembly on your average Caravan weighs in excess of 100lbs. |
300V+ gear is very expensive, and 300V is highly dangerous. You can put in an ADC 9" and 144V 1000A controller for far cheaper than a 300V setup.
Keep the transmission and you'll have much better than stock performance.
