We bought our first EV in June 2017,so we are just over a year on. We have a BMW i3. I'll admit we wimped out a bit and got the rex (range extender), due to range anxiety. Turned out at should have saved the extra rex cost, as it's barely been used. We very quickly got used to checking where charge points are available. We haven't ventured from Yorkshire to London yet, but that's mainly due to the fact that we need a larger car to transport my elderly father and his wheel chair when there.
We were keen to try electric, but were a bit anxious about the practicalities, especially as where we are, about 15 miles from Hull, public chargers are very few and far between. A quick glance at Zap map shows how poorly we are served here, in contrast to nearby York. But hey ho, hopefully it'll improve in time.
Having said this, we love the car and the experience. We also have 4Kw solar panels, so although we can't charge for free (the Pod point charger is 7Kw), by being smart with when we recharge we can reduce the cost when the sun is shining.
We did look into the cost of storage batteries for the solar panels, but it's really not economical yet. However, the idea of a smart charger, charging at optimal times, and feeding back into the grid at other times, is really attractive. Depending on the cost, we'll definitely be interested in installing one. What would be helpful for existing charge point owners would be a part ex scheme of some sort, to encourage a swap out to smart charging.
The biggest downside to our electric car is that it's too pricey to insure our 20 year old on it, due to the super duper nippiness of the motor. Hopefully in 6 months, when she's 21, it'll be more economical.
All in all though, I can't see us buying another ICE car. It's EV all the way for us from now on.
