Most delivery vehicles work 8am-6pm. Supermarket deliveries work with other schedules but also just for a few hours per day. That gives 14 hours charging window with (at least partly) low energy costs. For trucks that are not used a lot, this solution could end up cheaper because the battery can be used profitably while the truck is waiting.
