# Car parks and DC sites

Density and cost per plug: Plaza Charge puts up to twelve plugs on one shared 3×35 A connection for overnight top-ups. DC fast-charging sites use it to add cheap overnight AC charging for taxis, vans and buses.

## Car parks

Residents, employees and fleets park for the night. They do not need 22 kW; they need enough for tomorrow. [Plaza Charge](/products/plaza-charge) gives every car plugged in for at least 8 hours at least 50 km (cars that charge on three phases) on one shared 3×35 A connection. Cars can stay plugged in, and charging can follow a flexible energy contract.

## DC and fast-charging sites

A fast-charging site has the grid connection and the traffic. Fleets that return at night, taxis and delivery vans, want to charge slowly and cheaply while parked. Plaza Charge poles next to the DC chargers use the same connection at night when the fast chargers are idle.

## Parts

Plaza Charge poles; NFC readers; the platform with per-user or per-fleet reporting.
