I agree there with Rob that they are coming and I am really looking forward to it. Once Tesla can get this technology working https://www.youtube.com/watch?v=GJrsB0MJMsM my greatest fear of a $34,000 replacement battery after 7 years will put to rest as long as Tesla give the battery a million mile warranty as well so I know if I get a lemon I am not going to get stuck with the bill.

If the car is kept for several years the overall costs of ownership are way cheaper than ice cars as there’s no engine, exhaust, cat, radiator or other components to need replacing.


I have three customers with Nissan Leafs purchased two years or more old. None of them can get more than 70 miles in the best possible conditions, i.e. daylight, no heating or aircon etc. The batteries may not have to be replaced but they are nothing like 90% of the claim.

Unfortunately I have to agree with Nick, the few people i know with Leafs are not getting a good range and there are a lot of scary stories expensive battery replacements, you could easily replace every moving part in an ICE car for less. Maybe Canberra is just too hot in summer and too cold in Canberra for batteries to last. 43 degrees yesterday and -5 is pretty common in winter.

I think they use a heat transfer pump which is something like a reverse cycle air conditioner. Plus a radiator to cool the battery pack and the excess heat to heat the interior. This article is interesting. https://cleantechnica.com/2018/04/25/heat-pump-helps-audi-e-tron-trump-tesla-performance/

A friend of mine has built an electric motor bike that he races and really enjoys. He has done a great job and a real EV supporter but he still commutes on an ICE bike saying the main reason is the difficulty getting the EV bike registered. Talking to him he also agrees that the cost of batteries and the number needed to get any decent range makes it hard to build a practical EV vehicle for the road, the bike is setup with the least batteries for a short race. But he does try to encourage me to give it a go, I would love to build my own EV car if batteries could come down to a reasonable cost and weight.

Here is a police motor bike rider having a go on his bike, my friend in black is just telling the policeman that it is a 1984 bike with 1984 quality brakes but thanks to the batteries double the weight of the donor bike so don't expect it to stop like a new police bike would.
