Tesla specific requirements

As Tesla has specific requirements for using their Supercharger network any EMP wishing to use the Tesla network must follow these guidelines.

Access to the Tesla network is contingent to signing a contract amendment and fulfilling various requirements, in addition to making necessary changes to your App.


Geosearch

In addition to normal OCPI tariffs Tesla has introduced a new “type” and several new “restrictions”.


Type

In addition to FLAT, TIME, PARKING_TIME and ENERGY there is also CONGESTION_TIME. This is a duration based fee like TIME and PARKING_TIME but initiated by Tesla based on the “state of charge” and “location utilization” e.g. battery at 80% and location usage at 90%. It is recommended to provide an informative message in the app similar to Tesla has in their app.


Restrictions

Tesla has introduced the following restrictions:

  • Min_vehicle_soc – the price is effective when the battery state of charge is at this level or above
  • Max_vehicle_soc – the price is effective until the battery state of charge is at this level
  • Min_congestion_threshold – the price is effective when the location is at this level or above. Can be used for CONGESTION_TIME and PARKING_TIME.
  • Max_congestion_threshold – the price is effective until the location is at this level. Can be used for CONGESTION_TIME and PARKING_TIME.

Example

{'min_vehicle_soc': 80, 'min_congestion_threshold': 80}

This would mean when the location is more than 80% utilised and the car’s battery has exceeded 80% then CONGESTION_TIME starts.


Events

When a charging session starts to incur CONGESTION_TIME or PARKING_TIME Tesla informs Plugsurfing via an event. Often this means that the fee associated with this time will commence in 5 minutes, although this may change in the future. Tesla demands that the user is immediately informed when this occurs so that they are prompted to end their session so that others may easily find a connector to charge their car on. In order to use the Tesla network the EMP must listen for events with the “feeType” CONGESTING or PARKING and immediately inform their driver.


CDR

For now no changes are made to the CDR as Tesla is unable to provide data on how to calculate the congestion or parking fee. Therefore Plugsurfing is forced to pass on the CDR cost from Tesla when Tesla applies parking or congestion charges and this is seen in the price type FLAT i.e. a mix of energy and time based charges.
