I am going to try and address several comments.
As Far as Tesla saying that using Supercharger is better:
Not sure if this is still the case, opinions seem to change but,
Tesla would begin to limit the speed of the Supercharger after
a number of sessions. The claim was that it was for battery life.
I believe that All " Native " Tesla charging is DC.
From Las Year:
https://electrek.co/2017/05/07/tesla-limits-supercharging-speed-number-charges/Nissan has also come under fire for slowing charge rate after the first or second
fast charge on a trip. Their claim, again is because of battery heat generation.
Nissan Leaf uses passive cooling until the 2019 Model
As far as trickle vs fast, while all charging and discharging creates heat,
I believe that the longer slow charge sessions create less heat. This is
and has been the belief for as long as I can rember for all battery charging,
not just for EVs. I live in Las Vegas where ( on average ) the temperature is above
100 degrees more than 20% of the year, with the average high temperature closer
to 110 from May through September. This year, it was 113 degrees on the last day of spring.
I have been driving / riding EVs for more than a decade. I also run my house on
Solar and Batteries ( Big Lead Acid batteries ), and I have never noticed any heat related battery issues
I got my 2013 FX at about a year old. Maximum battery level was generally 95% at the time.
I could coax it to 100% but the return was negligible so didn't do it often. Today, it is still 90%~95%
on a full charge. Most if it's life it has charged from the onboard 650 watt charger with addition
of a Quik or Elcon charge now and then.
As far as " Value ", I don't think that anyone is disputing the Value of the SuperCharger,
just wishing that it was less expensive. There are always "options" for DIY, but, Brandon has put
the time effort and energy into making this as much of a plug and play as possible.
You are not just paying for the parts, but his time as well.
Regeneration, as mentioned, is a " fast(er) charge of a shorter duration. In most everyday
situations, you are not in a situation where this becomes an issue. Harlan told me years back
that they did not use regeneration on the race bikes. I believe that heat was one of the reasons.
Lastly, I agree.
