I live in an apartment block. So far I've charged my Vectrix at the public plug in the garage.
I'd like to extend my charging cable from my apartment to my garage parking space, so I can charge Vectrix on my electricity bill.
In the EU, we have 220-230V at the plug.
The length of the cable to the garage would be 80 meters and cable would be 3x2.5m2 thick. Now, the voltage drop at that length would be noticable (aprox. 4.25%) = 9-10V drop. So at the plug in the garage, I'd have aprox 210-220V.
Vectrix manual states, that the recharge requirements are 110V-230V.
Would everything be ok, if my charging voltage would be 210V?
Further more, if I buy Mitsubishi MiEV next year (or Citroen's licenced car), which charges, presumably, at 15A, voltage drop would be 7.8% = 17V. Do you think Vectrix' charger and MiEV's charger can handle 200-210V if they are rated from 110V-230V?
Is it better to install 4mm2 cable, even though it's more expensive?
