Electric Avenues - dear lord, HJ still peddling the myth that EV batteries will 'need replacing.'

HJ, how many EVs are you aware of that have needed their battery packs replacing? You can include first generation Leafs if you wish but a simple search of You Tube will find reports of Tesla's with over 200k miles and still on their original packs and, even venerable Leafs that have only 'lost' 4 and 5% of their battery capacity.

To the reader who wants to replace his Honda Civic and whom HJ advised to consider a BMW 2-Series Active Tourer: not only is your Civic worthy of a good trade-in price but the Active Tourer should come at a good discount. My BMW dealer tells me, off the record, that when BMW UK obliges the dealership to take an Active Tourer there are long faces all round as they wonder 'How on earth are we going to sell that?'

Actually, if you search hard enough, you will find reports of leaf batteries needing replacing.

However, look further and you find they are all in countries/places that get VERY hot in the summer.

The Leaf lacks certain battery thermal protection circuitry, and this coupled with high ambient temperatures has caused premature battery ageing.

Pure EV is the future, and I am watching the Swedish induction charging motorway research trials with great interest; it is something I suggested on the "Future Ecology and Alternative Fuel Sources" Birmingham uni course back in the late 1970's.

It depends upon how they're driven and stored - batteries don't like extremes of temperatures, and, I suspect, people in the US (who own most Teslas and will make up the vast majority of YT reports) where typically they do far greater annual mileages than in the UK, I'm not suprised that the batteries 'last longer' in terms of miles done, NOT age. A taxi doing 50-100k miles pa would be fine as most decent batteries (even AAs) drop a few percentage points in the first 2-3 years, then more so as they get older.

Battery effectiveness decreases throughout their life, so for the most part will only give a range of half that from new after about 7-10 years, assuming they still work at all (older generations). Newer batteries are better at keeping going at this age (10-12 years), but having a range of only 100-150 miles won't be of use to many, especially in the UK with our poor charging network and slow (relative to ICE cars) charging times (even for Teslas).

"For less money a new 7-seater Honda CR-V hybrid might make more environmental sense: /road-tests/honda/honda-cr-v-hybrid-2019-road-test/"

Are you sure HJ? Your road test seems to indicate that the CR-V hybrid is only available in the 5 seat configuration.

"Always best to insert a thin smear of high temperature 'Copperease' grease between the alloy wheel and an iron alloy hub."

Seems to be standard advice. Never really understood why antiseize, when ordinary chassis grease does the job, is cheaper, and more available (antiseize is effectively unobtainable in Taiwan, where I'm at)

Perhaps the reasoning is that chassis grease might melt, (never did, with me, but perhaps with more "spirited" driving), and/or if antiseize melts it will leave a residue of copper?

I've also used aluminium foil, which is a bit of a hassle. These days I use a thin sheet of polythene cut from a plastic bag. That does the job too.

"But the quick way to release corroded on wheels is to slacken the wheel bolts only slightly, leaving all of them in place, then lower the car back onto the ground and use the weight of the car to snap the wheel off the hub."

Using that method I've had to twice then take it for a run over some speed bumps, but I'm not lucky, and I buy rather old cars.
