    The holidays are hard on Tesla’s Superchargers, long lines reported, Barstow broken again

    [​IMG]

    There’s been a lot of talks lately about the upcoming Supercharger V3 with a significantly higher charge rate and while it could be a future solution to wait times at charging stations, it will not affect the current fleet, which is already having difficulties during high demand periods.

    The recent Christmas break was no exception and record wait times were reported at several Supercharger stations and an exceptionally long line at the Barstow Supercharger even made the headlines. more…

    In addition to idle fees, Tesla should consider whether repeat leave-and-disappear offenders should be fined with a significant penalty or be blacklisted with the offence counter reset annually.

    In deciding the penalty, Tesla will have to decide whether it is important to retain the rights of those who regularly abuse the system or the rest of the customers who are kind to fellow users yet have to suffer.

    Supercharger V3 eliminates all or at least most of this backlog. It's only going to get better, even with the rollout of the Model 3. Assuming they can implement V3 stations and broaden the Supercharger network in general, which they seem to be doing.

      Agreed. The goal is to reduce congestion - the goal is NOT to penalize Tesla owners. Penalizing owners is a short-term solution given the current situation. It sucks as a solution, but is better than doing nothing. V3 is the correct long-term solution, and I hope they can start rolling those out SOON.

        The thing is we don't have any idea as to when the improved Supercharger components will be deployed to the current network.

        All we have is an informal tweet from Elon that confirms they have something planned that will have higher performance. While I enjoy his off the cuff remarks it's frustrating to not have formal information from Tesla on the plans and timeline.

        The time to let everyone know is ASAP, preferably at the same time as the details of the credit system are announced, supposedly by the end of the year which is just days way. Hurry up Tesla!

          the quarterly call is coming up, so hopefully some info on SCing will come out of it.

            In an ideal world that is true.

            However, the reality is that the recently announced idle fee is indeed a penalty. Tesla is in a much better position to identify the best approach that also scales well into supercharger v3, v4, ... upgrades, the addition of further supercharger locations and the impending explosion in demand after model 3, model Y, and so on. IMO starting with the idle fee, Tesla has started to lay the groundwork in rules and procedures that would complement their effort to manage future supercharger supply and demand.

            I agree, it is. But the penalty is just a means to an end. It is not the goal. There are better ways to meet the goal of "reducing supercharger congestion" that don't involve a penalty (basically, faster charging & longer range vehicles), but none of those better alternatives can be implemented quickly enough to solve the immediate problem. And I agree that they'll probably keep the idle fee in place even when those alternatives exist, perhaps with some tweaks.

            In other words, I think we're in violent agreement. :p

              Can anyone speculate about the transformation of existing SCs to V3? Is it a software issue, new equipment or both?

              While having no personal knowledge, I can't imagine that that big of a juice boost would just be software. I would think there would be some serious hardware upgrades needed, but again...I'm no electrical engineer.

                Oh, it will definitely require new hardware. The cables will need to either be thicker or water-cooled (probably both) to handle that much power flowing through them.

                Also, the components on the car side may need to be updated as well. While the battery itself may be able to handle a higher current (given that it can dump ludicrous amounts of current to the motors), the charging components may not have been developed to handle much more than what current superchargers can deliver. We'll have to see.

                  Garsh, the SCs are DC, so the on board battery charger is not in play, just the wires to the battery.

                    @Badback There will also be some switching components in addition to the wires.

                      So for those of us that are COMPLETELY electric illiterate, will current cars, the way they are built now, be able to handle the new V3 Superchargers, will there need to be a physical update to current cars or will it not be possible for current cars to utilize the new charge speeds?

                      Thanks in advance for any info.

                      We're not sure. There might be some hardware upgrades required, or the current ones may have been designed to handle higher current. We'll just have to wait and see.

                      BadBack & I were just describing which parts could require an upgrade. It seems like it should be very minimal. So even if an upgrade is required, I would be cautiously optimistic that Tesla would offer an upgrade for current vehicles.

                        True, there is a contactor or a solid state switch, but are they not in the SC?

                        Yes, definitely. But I'm assuming that there is also something on the vehicle side, to isolate the charge port from the battery/motor system. I could be wrong.

                          You are probably right, otherwise the terminals in the charging port would have a dangerous DC voltage exposed.

                          shows a contactor in the vehicle, but this may apply only to the leaf.

                            How does a faster charger make a person who idles their car in a spot, leave faster? Faster chargers address a different problem from idle fees.

                            The limitation will be in the charging that any individual cell can take. There might be some room to charge faster into current packs; they are already near the recommended top charging rate, so not 3 times faster. After that, faster charging will require more cells per pack.

                            Thank you kindly.

                            If you make it fast enough, people will have no incentive to "idle". As proof, I give you "gas stations". If charging only takes 5-10 minutes, people won't bother leaving their car sitting there and going to dinner.
