Dwell time is how long a vehicle actually stays parked, the single variable that most determines the right charging power for a facility. In a parking facility:
- Eight hours of workplace dwell needs about 6 kW to deliver a full 48 kWh charge; a 40-minute turnover stay needs DC or nothing.
- Dwell is read from the facility’s own transaction data, not assumed.
Considerations
- A vendor proposal that opens with equipment rather than the dwell profile is a sales document. Dwell time is where every honest charging design begins.
