Table A7
The driver profile.
| Variable | Unit | Permissible value range | Description |
|---|---|---|---|
| Driver type | – | – | The driver type is an individualized instantiation of the abstract driver profile. It provides a range of values for each parameter. In this work, a “commuter” and “leisure” profiles were defined. |
| Daily driving distance | km | 0–180 km (Toyota) | This distance is covered on the days of the week that the driver profile specified (otherwise every day) and is split evenly over two trips (leaving home and returning home). The assumed boundary range is given for each vehicle technology based on its average fuel consumption and legal speed limits (max. 90 km/h in Japan). The simulation sets the average daily driving distance across the fleet according to Sun [69]. |
| 0–196 km (Tesla) | |||
| 0–143 (Nissan) | |||
| Driving hours | HH:mm–HH:mm | 00:00–23:00 | This refers to the specific period in which a car should be moving at an average speed so that the planned distance can be covered. During this period, an FCEV may decide to refuel but a BEV cannot decide to charge. For one trip the starting time must be earlier than the finish time. Further, the first trip of the day must end before the second trip begins. |
| Parking hours | HH:mm–HH:mm | 00:00–23:00 | This refers to non-moving periods that are not at home. These are automatically assigned to follow the first driving time of the day and to end when the second driving time begins. Home chargers cannot be accessed during this period. |
| Home hours | HH:mm–HH:mm | 00:00–23:00 | This refers to non-moving times when the vehicle is at home. These are automatically assigned to follow the last driving time of the day and to end when the first driving time of the next day begins. Any type of charger can be accessed during this period. |
| Driving hours flexibility | HH:mm–HH:mm | ±2 on weekdays | This refers to the permissible variability in driving times between subsets. That is, if the driving time is set to start at 8:00 with a permissible flexibility of 2 h, then the driving time of any subset could start between 6:00–10:00. |
| ±3 on weekends | |||
| Minimum want charge | % | 0–100 | This refers to the minimum fill level that the battery or tank has to reach for the driver to begin requesting a charger/HRS connection. If the attempt is unsuccessful, the driver will request again the next hour but not queue. |
| Minimum must charge | % | 0–100 | This refers to the minimum fill level that the battery or tank has to reach for the driver to queue after an unsuccessful charger/HRS connection request. |
| Driver type spatial split (MMA/rest of region) | Ratio MMA : rest of region | 0:10 | This refers to whether and how much bias for a specific driver type there should be between metropolitan areas and the rest of each region. For instance, at a 0:10 ratio for a driver profile, that profile would be completely absent from MMAs. |
