Main system
Transport
Moving people and goods by road, rail, sea and air, from vehicle technology to the way cities are planned.
Road, aviation, shipping and mobility
Electric buses and depot charging
Battery-electric buses charged overnight at the depot or briefly along their routes.
The problem
Diesel buses run all day in the busiest streets, adding emissions and local air pollution where people live and work.
Approach01
How it works
Charging is planned around timetables, so buses start each day full and top up where they wait.
Buses carry large batteries and run on electric motors, with no exhaust.
Most charge overnight at the depot; some also charge briefly at the ends of routes.
Timetables, routes and charging are planned together so every service can run.
Limitations02
Where it falls short
Depots often need a bigger grid connection, which can take time to arrange.
Range falls in cold weather and on long, hilly routes.
Drivers and maintenance staff need training for new vehicles and equipment.

Electrifying a bus depot
Planning chargers, grid connections and timetables around a battery-electric fleet.
Moving a bus fleet to battery-electric changes how a depot works, from its power supply to daily timetables.
