OK, so how is it that a TESLA can connect to a standard level 2 charger but the LEAF cannot connect to a TESLA charger?

If you could make the right adapter, a LEAF COULD charge from a Tesla Level 2 EVSE. Indeed, Tony Williams is modifying the Tesla portable EVSE by doing nothing more than hacking off the Tesla connector and substituting a J1772 handle.rawhog said:OK, so how is it that a TESLA can connect to a standard level 2 charger but the LEAF cannot connect to a TESLA charger?

That depends on your definition of "win", I guess. If you mean sheer number of chargers (and only in the USA), it appears that for the near term (5 years?) that you would be right. However, that does not make it a successful standard in my book. I do not believe that most (any?) of the other large manufacturers will adopt their "standard"...they will not be willing to pay a competitor the license fees.Nubo said:At this point I think Tesla will win the "standards war" for quick charging. They aren't bogged down by consortiums or the SAE and are free to design instead of spending years dithering about.

The Tesla Model S can connect to a Level 2 J1772 AC charging station using a simple mechanical adapter with no electronics inside. This works because Tesla planned ahead to be electrically and software compatible with J1772 before the standard was finalized. They chose to not be directly mechanically identical because they wanted to use a single port on the car to also support their DC Supercharger. In Supercharger mode the Model S port must be able to accept almost 300A DC at 120 kW, much higher than the maximum J1772 AC current.rawhog said:OK, so how is it that a TESLA can connect to a standard level 2 charger but the LEAF cannot connect to a TESLA charger?

Given this news I would think it would be possible to create an adapter. If they are willing to allow people to use their patents I would assume that would include the charging systems.
Agreed. However, perhaps we will see Supercharger hardware manufactured by third parties for sale to businesses and/or governments that want to offer Supercharging in locations not served by Tesla's network. I think this would be in the spirit of what Tesla is trying to accomplish.GeekEV said:Without having seen the patents, it's important to keep in mind that they can be pretty high level. They often address techniques and approaches without getting into implementation details. As the saying goes "the devil is in the details".

I have not seen anything that suggests this is the only way it could happen. I see no reason why other manufacturers couldn't take an approach of a pay-per-use scenario. I don't know if the superchargers have card readers of any kind, but there could be a smart-phone app that people might be able to use to authorize and pay for a charge at a particular station.
But until some way exists to physically plug a Tesla station into a non-Tesla car, it is sort of a moot point.
