During my initial planning, I got mired in lots of small optimizations that are not really my core design motivations. I remember hours spent talking about the "parking plug option" for a direct drive transmission as a must have feature. Regen is a nice feature of an AC system, but not a rationale for buying one.
<br><br>If budget and getting on the road quickly are important (they were for me) then start with a DC system. For example, Larry Elliot (another electric RAV4 linked from my blog) wanted an EV showcase for his 3rd project so he chose AC. If you want to maximize your range or performance then consider an AC system and/or advanced batteries.
