Separate energy from power
Daily energy answers how much electricity the fleet needs. Peak power answers how quickly that energy must be delivered. The charging window links the two, but departure priorities and charger sharing determine the practical load profile.
Build a half-hour operating model
Map vehicle arrivals, required energy and departure deadlines in half-hour intervals. Add the site's non-vehicle load, then test normal days, peak days and a disrupted operating day.
- Existing maximum demand
- Fleet charging demand by interval
- Control limit and reserve
- Future vehicle growth
Compare upgrade and flexibility options
Compare grid augmentation with managed charging, on-site generation, battery-supported peaks and staged fleet conversion. The lowest-capital option is not always the lowest-risk option; operational resilience and expansion cost matter.
