What is EV charging simulation for a fleet depot?

EV charging simulation models how buses or trucks return overnight, plug in, and draw power under a chosen strategy. A good depot run reports charger need, readiness by first pull-out, and high-percentile peak demand (kW) so operations and the DNSP see a credible planning case — not a single average night.

What is EV depot charging?

EV depot charging means restoring fleet energy at a home yard or operations base — usually overnight for route buses, and overnight or between shifts for many trucks. A useful plan states charger count and kW, readiness by pull-out, and P95 peak demand in kW against site supply in kVA. It is not public fast charging and not a residential wallbox.

How many chargers does an electric bus depot need in Australia?

Charger count depends on fleet size, daily kilometres, battery size, charger power (kW), and the overnight window. As a planning rule of thumb, many Australian route-bus depots land between roughly one charger for every 2–4 buses when using 80–150 kW depot chargers and smart charging — but Monte Carlo simulation is more reliable than rules of thumb because arrival state-of-charge and energy use vary night to night.

What is smart charging for an EV depot?

Smart charging spreads vehicle charging across the overnight window instead of plugging every bus or truck in at full power as soon as it returns. That typically lowers P95 peak demand (kW), reduces demand charges, and can keep a site under its DNSP supply limit without buying as many chargers.

How do I estimate peak power demand for a truck or bus depot?

Peak demand is driven by how many vehicles charge at once and at what power. Uncontrolled charging often creates a sharp evening peak. This EV charging simulation runs Monte Carlo scenarios and reports P50, P90, and P95 peaks so you can plan for a high-probability night rather than an average night.

What grid connection do I need for an Australian EV depot?

Connection size is usually discussed in kVA with your DNSP (for example Ausgrid, Endeavour Energy, Essential Energy, Energex, or SA Power Networks). This tool maps simulated peak kW to indicative connection bands and lead times. Always confirm with the network before procurement — augmentation can take months to years for larger sites.

Can smart charging reduce electricity costs for fleets?

Yes. On commercial Australian tariffs, demand charges ($/kW/month) and time-of-use energy rates mean lower peak demand and more off-peak energy can cut annual cost. The simulator compares smart or peak-limited strategies against uncontrolled charging using indicative Ausgrid-area and other network blended rates.

Is this tool suitable for council bus depots and freight operators?

Yes. Presets cover small, medium, and large bus depots plus a medium truck depot. You can switch to Australian vehicle models (for example BYD, Yutong, Volvo, Fuso), climate and terrain modifiers, and export a CSV load profile or printable feasibility report for internal and DNSP discussions.
