What I did for my ZS EV was to put the supplied charger out for cell balancing charges and install a 7 Kw charger outlet programmed to feed excess power from my 5 Kw solar roof panels to the car before feeding it back to the grid. OK, so I live in Northern New Zealand at 36 South, but over the first year over 93% of my driving has been using solar power despite a very bad summer.
My type 2 plug is locked in place unless the car is unlocked. The real point is that a plug in mains charger is limited to about 2.2 kW hours per hour of charge in NZ and about 3 kW in the UK because you have 13 Amp outlets instead of our 10 Amp ones. Under good conditions my fixed installation is giving about 4 kW hours per hour from solar energy and that supplies almost all my driving. So far electric vehicles are much more practical in NZ because of our weather and latitude. The only problem so far is an inadequate number of charging stations but this is finally being adressed
An odd new problem has arisen lately, I have a mobility sticker (I am 82) and far too often see drivers without one taking up mobility parking spaces. Now something new the other day. The driver of what I refer to as "Gas Buggies" parking his car in one of the only 2 charging points in a local retail area!!!
