Robert:
Current solutions:
- Card in the Car
- App on the mobile phone to start stop charging.
Discussion:
Michel:
Stay aware of eMI3 use cases on car sharing.
There is a eMI3 meeting next week.
Michel will provide feedback.
Michel:
I see 2 types of car sharing:
- Renting
- Sharing in a closed community:
- Group of known users (5 to 6 families), sometimes guest users.
- Supported with an app.
- Diffent
Reinier:
I see a 3th type: Company Cars
Ali:
2nd case can be solved with the existing ParentId in OCPP.
Michel:
Does car sharing have impact on billing?
Robert:
Is billing the responsibility of OCPP?
Ali:
Proposes to always authorize an RFID card at the server for scenario 1 (renting)
This way the server can always check if somebody is allowed to start/stop any transsaction.
Robert:
This might be a solution, we need to add a field to the authorize.conf telling the charge point to stop/start a specific connector.
How about off-line scenario's? Somebody rents a car, but cannot stop the transaction, Charge Point is off-line, driver wont be happy.
Sibo:
Chargelink with a partner is doing tests in the car sharing market:
Proposes to Tunnel credentials through OCPP, no matter what the credentials are, the Charge Point should do nothing with them.
Problem from the field: somebody parking the car but not starting the charging.
They are testing with a sensor in the parking lot, combined with embedded system in the car and the charger to detect car parked but not charging.
They have a SIM card in the car for for example location monitoring.
Michel:
CarToGo has some kind of check to see if car is parked and charging, if not you will get a penalty.
App on the mobile phone to open/close car, start stop charging: using the RFID on the phone.
Zach:
Are looking into a blend between Company Car Sharing and Community Car Sharing.
After business hours open for public.
Using Honda fit EV
App to unlock the car.
Unlock the cable by unlocking the car.
Car can charge always charge at a Charge Point, no credentials (RFID) required.
Michel:
Locker that detects if the key is back in the car
Try to get in contact with CarToGo
Ask BMW for input
Robert:
Kor (Allego) is in contact with BMW.
They leave the RFID Card in the EV.
Sergiu:
Lives close to a company that makes most of the boxes used in car sharing projects.
Has no direct connection to them.

Brendan:
Rental company could require a vehicle to be returned to it home location.
Ali:
We should authenticate the car.
Robert:
With 15118 Plug-n-Charge that should be possible.
Michel:
Check eMI3: There are no use cases in eMI3, will ask next week.
Ali:
Could we create a Group of parentIDs?
Brendan:
ParentId should be GroupId, more clear, this was proposed for OCPP 2.0
Problem is that any RFID can only be part of 1 group.
Reinier:
By allowing multiple parentIds we can make OCPP more flexible.
Lambert:
Allowing a list of groupIds in every token will use up a lot more memory in a Charge Point.
Think about the Cache and White-lists as well.
Robert:
Would this really be used, most likely you will get 1 RFID card for every group.
Look at the current RFID and SmartCards, they all can be used for more then one service and
we still have 1 for every service.
If you would be using 3 different Car Sharing services, they will all want to give you there own RFID card anyway.
Group/ParentId is currently almost not used anyway.
Michel:
Group/ParentId will be used for Car Sharing.
Rental Charge Points are not allowed to be used by other cars.
Conclusion:
Robert:
For now we don't see reasons to extend OCPP for Car Sharing.
For scenario 1 & 3 the current ParentId/GroupId will work.
No need to allow more then 1 GroupId.
Scenario 2: rental, these always need to be returned to rental location.
Chargers at rental locations will probably not be allowed to be used be non-rental vehicles.
They have to be available when a rental EV returns.
They will most-likely be behind a barrier and allow all EVs that can reach them to charge.
15118 Plug-n-Charge could be used in the future to allow only certain vehicles to connect.
