Not hybrid obviously.

Has anyone done a study on electric bill changes when buying a full electric vehicle.

Thinking on the lines of someone who does a fairly regular/constant  xxx kilometre a day, say work and back.

I suppose it would require a record of home electric bill over say a 6 month or year period pre car purchase compared to the same period post car purchase.

Car cost or insurance not factors to come into it. Only electric bills to be looked at.

As has repeatedly been pointed out elsewhere, cars can be charged overnight, when rates are much lower.

 

Here's a link to a article that discusses how much it would cost to charge a Tesla in the USA. You can easily substitute Thai rates for those in the US

Simply consider the size of the battery.  MG ZS for instance is 50Kw, and 1 unit of PEA, is approx 4.25 per.  0-100% charge would be in the ฿215 +/- range.  Depending on driving speed / load, MG ZS estimates / rated at 403 kms @ 37 kph (NEDC), or 320 kms @ 47 kph (WLTP). http://tiny.cc/tpkpuz

 

So I would personally expect about 200 kms for an 80% charge top up, if just around town driving, to avoid going below 20% reserve.  Always good to calculate on the negative side.  Would hope to squeeze 250 kms around town, but really depends, if using all options, AC, sound system, lights/night driving, 1 or 4 people load.

 

We don't drive more than 200 kms a week, so about 800 km for the month, if that. 

EV cost est: ฿690 (high end est) vs ICE cost: ฿2352 (exact cost)

MG ZS (800 kms / 11 kpl = 72.72 L X 32.34 (E85 today)
