Rækkevidde
Hvilket interval får du faktisk?
Det officielle tal er et laboratorieresultat ved en moderat temperatur. To ting bryder det på en virkelig rejse: vedholdende hastighed og kulde.
Hvorfor hastighed koster så meget
Ved byhastigheder går det meste af din energi til at accelerere massen, og regenerativ bremsning får en god del af det tilbage. På en motorvej gør næsten ingen af det — du skubber luft ud af vejen kontinuerligt, og den omkostning skalerer med kvadratet af din hastighed, mens den krævede effekt skalerer med kuben.
Den praktiske konsekvens er, at forskellen mellem 110 og 130 km/h er meget større end de 18% hastighedsforskel antyder. På en lang køretur sparer det ofte en ladestop at sænke hastigheden med 20 km/h, hvilket sparer mere tid, end det koster.
Hastighed og forbrug
Vinterstraffen
To effekter kompenserer. Kabinen har brug for opvarmning, og i en bil med resistiv opvarmning, der trækker direkte fra trækkraftbatteriet. Og pakken selv accepterer og leverer energi mindre villigt, når den er kold, hvilket også bremser hurtig opladning. Studier, der måler effekterne af omgivelsestemperatur på forbrug, kvantificerer det samlede resultat [1].
| Betingelser | Planlæg for | Bemærk |
|---|---|---|
| By, mild | 100% eller bedre | Regenerering arbejder til din fordel |
| Blandet veje, mild | ~85% | Tæt på den officielle cyklus |
| Motorvej 110 km/h, mild | ~75% | Modstand dominerer |
| Motorvej 130 km/h, mild | ~65% | Den kubiske effektforhold bider |
| Motorvej, nær frysepunktet | ~50-60% | Opvarmning plus en kold pakke |
| Træk eller tagboks | Meget mindre | Frontalarealet er fjenden |
