hello, i have not yet bought a PHEV, still in the research phase, but its looking like the best option for me, anyway, i have noticed during my research about Nissan Leaves, and other pure EV's there is a thriving "hacking" culture around the cars, such as adding additional battery capacity to the Leaf, to get longer range, etc, i have seen the Pure EV mode, and like that a lot, but there is nothing about adding to the PHEV battery, or replacing it with higher capacity cells, or different pack altogether to give better EV range. fortunately, i like to tinker with things and Hack them, to modify things, but sadly there is no hacking scene with the PHEV outside of the pure EV box mods.(that i have found) is there anyone modifying PHEV's in other ways? things like trying to get a i-miev battery pack to replace the PHEV pack, for that little bit extra? or adding another PHEV pack, so to double the existing capacity? or will i be on my own with this sort of hacking?
