1000 cycles, is what roughly 4-years for your average commuter? I hope they are cheap to replace every four years.

Here in NS we still use coal, but it is being phased out. I dunno why they don't run a pipeline from some close by gas fields like sable Island to the coal fired plants and switchover while we upgrade to renewables and energy storage. We have enough wind, wave and tidal power to do the job, with adequate energy storage to stabilize the grid. Turbojet generators running on NG can fill in occasionally when the wind doesn't blow, which isn't often! We are sitting on mountains of coal here in CB and there is plenty in NS, it will remain in the ground and eventually the tar sands in Albertastan will be left there too.

Hydrogen Will Not Save Us. Here's Why.

Replacing fossil fuel with hydrogen seems like an ideal solution to make transportation environmentally friendly and to provide a backup for intermittent energy sources like solar and wind. But how environmentally friendly is hydrogen really? And how sustainable is it, given that hydrogen fuel cells rely on supply of rare metals like platinum and iridium? In this video, we have collected all the relevant numbers for you.

You may know more about this as you're an EV driver if I recall correctly, is a cycle not considered the full use of the battery capacity? So the standard range Ford Lighting that has 230 mile range, 1 cycle should be 230 miles unless overly harsh conditions? Thinking about getting in line for an EV soon, so trying to compare with the latest ICE's and still pretty confusing. If 1000 cycles is only 4 years, not sure it makes sense for me to keep looking at EV's.

We must have just about the same YT feed. I saw that vid earlier.

We agree on something!

Also being rear ended followed by the potential to explode isnt an ideal thought.

We may not agree on EVs though. If you scale up production in an attempt to replace combustion engines, the environmental impact would be devastating, the amount of lithium needed isn’t sustainable and mining it uses an extremely valuable resource: water. Unless lithium is somehow replaced (which isn’t likely in the near future.)

It depends on your terrain. Around here a lot of people commute "over the hill", and a round trip would be pretty close to a full cycle in real world conditions. Of course, you also don't want to be driving down to zero percent on a regular basis either.

I was under the impression that if you start at 100%, drive to say 50%, charge back to 100%, then when back at 50% it would be considered 1 cycle. I can see significant savings and justify the larger upfront cost as long as battery would last 10+ years, shorter than that assuming battery costs don't drop significantly, not sure it makes financial sense. Would you get another EV or go with an ICE if you had the option?

Yes, I think that your assessment is correct in terms of drive cycles. I think that I didn't explain the terrain issue well. In my case I have an older (2016) Leaf, so it only has a 24kWh battery pack. It's rated for 100miles. To get that 100 mile range, you need to be driving on a flat level road at a moderate speed. Once you go above 65 you are losing range. Once you have to go up hills, you are losing range. When you accelerate you lose range. You do gain range downhill or when stopping, but not enough to make up for the losses. My car being a 2016 has also lost some range. One a full charge under ideal conditions, I'm at 85miles range on a "tank", but I also don't really like going below 20% charge unless I know that I will have a place to charge up soon, so that makes my range more like 70 miles. If I were to drive from where I live to San Jose, that's around 45 miles, but due to the fact that I have to drive over a hill, it will take my entire charge to get there, so ,my range is effectively halved.

Would I get another EV? Absolutely, yes. Would I also own an ICE vehicle? Absolutely, yes. I currently have both, plus my motorcycle. I pick the vehicle to drive depending on specific needs. I do need to buy another vehicle in the next year or so, as my ICE car is getting old. I only keep it because it still runs, and I need it from time to time. I will most likely get a truck next. I need a truck again.

After market batteries are starting to appear, prices plummeted for cells and they have gotten better. More options are coming, an EV shouldn't wear out very fast, if a rebuilt pack is used. Look for more 3rd party options that will improve performance as the aftermarket industry grows.

That explains the range/cycle issue I was confused on. Thanks for giving more detail on the terrain issue, wasn't something I even considered but need to pay some attention to. I will need to factor in cold weather adjustments and if going with a truck, what weight and/or towing does to range. Can't imagine it will be long before there is a trailer chassis that has its own battery and drive system that connects to the vehicle so there is no range losses when towing.

I will definitely keep one of the ICE vehicles for the foreseeable future, just trying to determine if the wife's super short commute in a far less expensive EV makes more sense than my requirements of larger work truck that would save more due to distance driven daily.

Thank you, I appreciate the feedback.

my little Honda actually gets better mpg on a mountain round trip than a flat one, unless the wind is upslope.

I'm not sure if this is the best place to put this, but it does have a little climate related content. (it could have gone into the covid or GOP leadership threads)

Honestly I've been pretty happy with the battery pack in my 2016. I'm over 65k miles on the pack now, and it's only dropped 1-bar (out of 12) of it's capacity. I'm guessing that the 2nd bar will drop soon though.

Cold weather (and hot weather too) is also a range consideration. If you operate the heater or AC it will deplete your range as well. Luckily I live in a pretty moderate climate, so rarely need AC, and can also generally survive in the winter without the heater if necessary.
