City driving rarely tests an electric vehicle's range. Highways do. For long-distance travel to feel normal, drivers need to know there will be a working fast charger at sensible intervals, and that it will not leave them waiting in a queue. Building that confidence takes more than placing chargers on a map.
Spacing that matches real range
Advertised range is measured in ideal conditions. At highway speeds, with air-conditioning on and a full car, real range drops noticeably. We plan corridors around a conservative usable range and a reserve, so that a driver who skips one stop can still reach the next. Gaps are most dangerous in hilly sections and between major towns, so those get closer spacing.
Power levels for different vehicles
- Cars: 60–240 kW CCS2 chargers bring most vehicles from low charge to around 80% during a meal or rest break.
- Buses and coaches: 240–600 kW chargers fit the short layovers of intercity routes.
- Heavy trucks: megawatt charging up to 1,200 kW lets long-haul trucks recharge during mandatory driver rest periods.
Sites that will see trucks need very different layouts, with drive-through bays long enough for a tractor and trailer, separate from car charging.
Power availability decides the site
The best location for drivers is not always where power is available. Highway sites often sit far from substations, and new high-voltage lines take time. We assess grid capacity early, and where it is short we look at phased power build-up, battery storage to support peak demand, and local solar generation to reduce reliance on the grid.
A corridor plan should show not just where chargers go, but where the power for them will come from in year one and year five.
The stop itself
A fast charge still takes long enough for a driver to want somewhere to go. Charging works best alongside food, clean washrooms, shade and safe lighting at night. Partnering with existing highway restaurants and fuel stations makes the stop useful and gives site hosts a reason to invest.
Reliability is the brand
One broken charger on a city street is an inconvenience. On a highway it can strand a family. Highway sites need redundancy, with more than one charger per site, remote monitoring that flags faults before drivers find them, and maintenance teams that can reach the site quickly. Clear, live availability information in apps lets drivers plan around any problem.
Building corridors with PxT
PxT Energies works with highway authorities, site hosts and fleet operators to plan, build and operate charging corridors, from the first route study to round-the-clock monitoring. If you own land or hospitality sites along a major route, we would like to talk.
