If you have an EV that has a maximum range of about 130km, what would you expect it would cost to charge this vehicle overnight at home to 100% assuming that the battery had gone down to 10km range? The old model BMW i3 might be an EV that would have this sort of range.

I realise that the answer to this depends on what electricity company you are with and where you are located etc, so a rough estimate would be helpful, thanks.

I'd guess that it would cost around $4.

I would expect to go through under $2.50 per day to recharge for my 70km return trip to work and back.

Yes, petrol vehicles will be here a long time, the market will manage that. EV upfront cost, lower maintenance, low fuel costs and the ICE equivalents.

Where to charge? Home, work, supermarket, parking meters, parking buildings, a lot of that is quite easy

funny , driving around the area where i live i dont see any of those things . Guess you live in a big city not like the majority who live in Rural and small town NZ.

Have a look at Plugshare.com.

Where do you live?

A typical electric car can charge from any 3-pin wall socket (2.2kilowatts). A car with a smaller battery - like the 24kWh LEAF - can fully charge from empty to full in about 10 hours (that's the maximum) this way. The most you can charge one of them is to 22.1kw....which is 2.2kw for ten hours. If you install a 16amp "blue commando" (campground) power socket (3.3kw) then that same car will charge from empty to full in about 7 hours. That's 7 x 3.3kw = about 22kWh.

If you have a LEAF with a 6.6kw internal AC charger (I do), then you can charge at 32amp (7kw) and you'll be able to charge the car from empty to full in 6.6kw x (about) 3.5 hours.

This can all be done at home....or wherever such a power point if available. They are relatively cheap to install.

If you want to charge really fast, then the current 'standard' is 50kw DC....and a car that only needs 22.1kw will obviously charge from empty to full in about half an hour. I typically top up from about 30% to 80% if I need to and it takes under 15 minutes. Barely time for loo break and a *very* quick flat white - allowing for ordering it, they make it and then you drink it.

A year ago there weren't many fast chargers. Now there are a lot more and you can easily drive from Auckland to Wellington via Napier or SH1. The gaps in the rest of the country are being filled in.

You probably don't notice the chargers because they don't take up much space and can be located pretty much anywhere....as there are no hazardous or flammable chemicals to worry about.

But have a look at Plugshare...and remember all those campgrounds are perfectly good for a top-up if you need one should there still be a gap in the fast charger network.

Bottom line....it's do-able for anyone who wants to do it....and it's easier every day.

In terms of cost, if you use 22kWh of electricity to charge from empty to full, then we would pay about $6 for this. I know we aren’t on the cheapest electricity plan available, but I guess it still represents very good value compared with filling with petrol?

The only thing, of course, is that you have to charge up a 24kWh EV several times to travel say, 750km, but this range is easily obtainable from a single petrol fill if you have a 40 litre (or greater) petrol tank.

40 literally for 750kms!
My ‘trusty 1.6l Corolla only gets 550ks on a ‘good’ tank with freeway driving 😀

He might be talking about some hybrid. Or confused petrol for diesel. I wonder what Ford's 1L turbo that fits in a briefcase can produce, but in that instance you'd be walking home coz it probably breaks down.

Involuntary autocorrect in operation on mobile device. Apologies in advance.

As an example, the Honda Jazz RS CVT is quoted as requiring 5.4 litres of petrol per 100km. So, with a 40 litre tank, you would get about 740km of range. In "real world" driving it might be a bit less than this, but I think 700km would probably be achievable with careful driving.
