Stop
Hvor mange ladestop kræver en rute?
Peak opladningskraft er et marketingtal, der kun gælder i et par minutter. Hvad der bestemmer din rejse er gennemsnitlig effekt over det vindue, du faktisk bruger.
Opladningskurven
Et batteri accepterer ikke energi med en konstant hastighed. Effekten er højest ved lav ladetilstand og falder, efterhånden som pakken fyldes, fordi det at presse strøm ind i en næsten fuld celle risikerer lithiumaflejring og permanent skade. Modeller for hurtig opladning på celle-niveau beskriver denne adfærd direkte [3].
Så to biler, der reklamerer med samme peak-effekt, kan variere med femten minutter på det samme stop, afhængigt af hvor længe hver holder effekten, før den falder. En bil, der har en lavere top, men holder den fladere, er ofte hurtigere i praksis.
Opladningshastighed og ladetilstand
Hvorfor 10-80%
Under cirka 10% risikerer du at ankomme uden margin. Over cirka 80% er faldet så stejlt, at du venter længe på en lille mængde energi. Opladning fra 80 til 100 kan tage lige så lang tid som 10 til 80 gjorde.
For en lang køretur slår to 10-80 stop næsten altid et 10-100 stop plus et kortere andet. Undtagelsen er den sidste etape, hvor det giver mening at oplade højt én gang, fordi du ikke betaler tapergebyret to gange.
Stop er også for dig
Forskning om førertræthed understøtter konsekvent regelmæssige pauser på lange ture, og det interval, der fremkommer, er tæt på, hvad en moderne elbil har brug for. Det stop, du fortryder som en opladningsbegrænsning, er et stop, du bør tage.
Det, der gør det tåleligt, er, hvor du stopper. En oplader i en ubelyst detailparkering uden faciliteter er en anden oplevelse end en, der er knyttet til et sted, hvor du ville spise — hvilket er tilfældet for vores motorvejs madsite.
