Interval load data
Use actual site demand and available-capacity data rather than the entered planning allocation.
AETRENCharging Infrastructure Systems
Capacity Planner · Scenario V2
Test the charging duty against an entered site-power allowance.
This planning tool converts vehicle count, energy need, dwell time, simultaneous use, charger class and an entered charging-power allowance into a concept duty profile. It does not calculate network maximum demand, cable/protection sizes, transformer capacity or electrical compliance.
Operating + site assumptions
Use measured fleet/site data where possible.
What to verify next
Turn the scenario into an electrical and operating brief.
The project team should now close measured site capacity, vehicle compatibility, charger architecture, load management, backend, climate, payment/access and destination compliance.
Vehicle compatibility
AC onboard limits, DC capability, connectors, duty cycle and future vehicle mix.
Managed charging
Define whether chargers share capacity dynamically and what priority/fairness rules apply.
Power quality + protection
Transformer/service, protection, earthing, isolation, harmonics and cable design remain local electrical work.
Climate + derating
Ambient heat, direct sun, dust, salt and enclosure thermal behaviour can reduce usable output.
Backend + resilience
OCPP, payment/access, network failure behaviour, reporting, remote support and redundancy.
