Exactly the point I was trying to make. Even that relatively slow "fast charge" speed is likely damaging the battery. The battery won't be any cooler in a warmer climate or when driving at 80 mph, which is what one does on long road trips in the many states that have that have high speed limits. Add in 100 kW Supercharging and it figures to be damaging to an uncooled battery. (By the way, when driving and Supercharging like this, the Tesla cooling system is going full blast when one pulls in to a Supercharger Station and it keeps going for quite some time, and again periodically during the charging session.)DaveinOlyWA said:try QC'ing at 125 amps up to 85%. I see 10 TBs every day.... like right now but then again, its not all that cool today
I expect that Tesla would be pleased to have Nissan or another manufacturer join in the Supercharger network for just the reasons you (and others) state. But the cars would have to be able to fast charge at Supercharger speeds without damage and the LEAF just isn't there yet. With current battery technology I don't think any cars can charge at Supercharger speeds without some sort of TMS. Slow charging at 50 kW or less just clogs up the stalls and would not be practical (or allowed by Tesla). Hence, my position that Nissan isn't likely to join the Supercharger network unless the coming cars have TMS.Nubo said:evnow said:Here is the question to all the people who hope someday, somehow Leaf will support Tesla SC.
Its very clear it would be advantageous to Leaf owners. But what is in it for Tesla ? Afterall with Model 3 the fear is the SCs would get heavily clogged.
Exactly why Tesla might be interested in a venture to expand SC infrastructure, sooner rather than later. Having a manufacturer the size of Nissan join would be a strong move towards SuperCharge becoming the de-facto standard.
It would make sense only if Leaf pays so much money to Tesla that Tesla can build more SCs that will lessen the expected clogging - even while adding more cars (Leafs). That can't be cheap - and Nissan would have to pass on that cost, and given the target market of Leafs - few would be willing to pay that cost....
As the saying goes, "Skate to where the puck is going to be". Nissan's EV program won't end with LEAF, nor is their target market static. Enhanced distance facilities expand the target, and ChaDeMo just isn't going to win the standards war -- a significant roadblock. Cost? Yes, but it doesn't have to be amortized over just LEAF production. Again, take the long view. Tesla and Nissan cooperating in such a fashion could be synergistic. I.e., double the size of the SC network, and the attractiveness to both Tesla and Nissan owners could grow by much more than a factor of 2.
So far as the fast charging "standards war" goes, I think that the Tesla version may be replaced eventually by CCS; that already seems to be happening in Europe. Tesla's is more elegant, to put it mildly, but with so many other manufacturers putting their weight behind CCS it seems likely to win out in the end. Or, perhaps, something better will come along (although I have little patience for inductive charging — favored by some — due to inefficiency).
