Choose a passenger van over a particular commercial electric vehicle when the electric candidate cannot accommodate the required passengers, luggage, access needs, or operating schedule. An electric cargo van is not a substitute for group seating simply because its exterior is van-shaped.
The categories overlap: a passenger van can itself be electric. Passenger van describes a vehicle's accommodation, while commercial electric vehicle describes a broad business-use and powertrain category. First compare vehicles capable of the same passenger task. Then decide whether their range, charging, refueling, and service arrangements fit the route. For battery-electric vehicles, charging must support the complete assignment; plug-in hybrids also have an engine and need a separate operating assessment.
