The bigger battery costs more to fill but is not necessarily more expensive to run — cost per mile depends on efficiency, not battery size. Costs include ~12% AC charging losses, and both figures rise in the cold — typically 10–30% in winter. On an off-peak tariff both cars cost roughly two thirds less per mile.
