Energy
A small battery, charged often, from a charger that carries its own.
Fast charging where the grid is thin
A fast charger draws a lot of power for a short time. In a dense, historic district the connection to do that either does not exist or takes years and a substation to build.
A battery-buffered charger decouples the two. It draws a modest, steady feed from an ordinary connection all day, stores it, and releases it quickly when a vehicle plugs in. The site needs a wall socket's worth of grid and gets a depot's worth of charging.
The QAF depot unit
Supplied by an established maker of buffered charging systems and white-labelled for the fleet, so vehicle and charger arrive from one supplier with one warranty.
| Buffer | 100–140 kWh lithium iron phosphate |
|---|---|
| Grid feed | Three-phase, from 32 A |
| Outputs | Two CCS2 leads, up to 60 kW each |
| Climate | Rated for 50 °C ambient, shaded installation |
| Turnaround | 20 to 80 % in about 20 minutes |
| Vehicles per buffer | About eight before the unit rests |
Inside the network that exists
The Kingdom already has a national charging network and the operators to run it. QAF depot units sit inside that world, not beside it.
Every QAF charges on the same CCS2 standard as any other electric vehicle in the Kingdom. The depot units use open protocols, so an operator can bring them into an existing back office, meter them, and manage them from the same screen as the rest of its estate. King Salman Gate is planned around seamless connection to public transport; QAF depots sit at those interchanges, where transit stops and the walking district begins.
