The adapter has a firmware. This firmware must be updated at the service center from time to time. I assume updates could be:
- Better stability by improving hand shake
- Throttle the power so certain charging stations don't overheat
- Increase power after seeing that certain charging stations can handle higher load over time
- Bug fixes
If the business holds on to it, the adapter will most likely never be updated. Whereas a Model S owner will easily be able to update it. The 90/10 split was just an estimation. We don't know yet which one will work best. Maybe it will be 50/50 if the response from the business are good.
However, I want to involve 24/7 business only. From my own experience, people need charging at any time of the day/night. Having to plan or rush to get to a charger before the business closes is a serious disadvantage. Being able to refuel at any time is as important as being able to charge at any time.
If somebody has borrowed the item for 1 week and doesn't return for 4 weeks, how is that going to work? There are so many problems with this idea.
I will write a policy for lenders and borrowers. The borrower should estimate how long the adapter is needed. If there is a change in plans, let the lender know. There could also be a 1 week free loan and then some fee for every day over.
There are problems and disadvantages with all solutions, including the restaurant solution. Solution A (Model S owner lend) was supported by many Norwegians who will go on a Europe road trip. We can't cover up all of Europe with adapters. And we don't know which one will be in use. Some Norwegians go to Spain. Some go to Croatia. And some go to Italy. Same goes for foreigners coming to Norway. Some go to North Cape. Some go to the western parts. This solution suits for those "holiday drivers".
But I agree that popular charging stations should have a dedicated adapter available. It just needs to be worked out. So far I have one feedback from Fortum (
Fortum Markets - En av Nordens største strømleverandører
). They have provided one adapter at a charging station in Nes (Ådal). I suggested doing the same in Oslo near E6/Furuset where there's a McDonald's. His response was that the restaurant will have to prioritize their food customer.
So the best solution for the charging customer would be to have the adapter locked to the charging station.
Pros:
- Fast and easy to use
- No need to deposit anything
- Available 24/7
Cons:
- Susceptible to vandalism, weather and schmutz
- Firmware won't be updated
- Could get stolen
I wonder if it's possible for Tesla to see who's using a specific adapter. Each adapter have its own serial number. So if I would report an adapter as stolen, they could possibly find out that the adapter is being used by which car. Even if they can do this, there's not much the customer can do due to privacy. It's highly unlikely they will give any information for such a small crime. It has to be serious crime before they can hand out information. And even so, it must be directly to the police and not the owner.
