Depot Charging
Charging infrastructure located at a central facility where fleet vehicles return to park and charge, typically overnight.
Technical Details
Typically involves lower power DC chargers (50-100kW) or AC chargers (22kW) compared to public fast-charging, as dwell times are longer.
Fleet Applications
The primary charging model for public transit and logistics. Requires careful layout planning to match parking workflows and operational schedules.
