EV infrastructure feasibility modelling and design

EV Charging

EV Charging Infrastructure feasibility, fleet modelling and detailed design. Depot 112 Vehicles, Civic Centre 39 Vehicles.

Key Achievements:

  • EV Fleet electrical demand modelling of medium and worst-case charging scenarios.
  • Detailed modelling proved that expensive grid upgrades were not required; and with load management of EV infrastructure, all vehicles could be charged when and as required.
  • Detailed design of internal electrical infrastructure, chargers and load management systems.

Project Scope

  • Feasibility assessment and preliminary design, strategy, and cost estimate for Electrical Vehicle Supply Equipment (EVSE).
  • Assessment of existing Electrical infrastructure by in-house electrician.
  • Modelling of future EV fleet electrical demand and requirements, including load management systems, to minimise capacity of grid supply whilst ensuring all vehicles can be charged when required.
  • Detailed design for costing and for construction.

Project Details

  • Two sites assessed including Depot (117 Vehicles including 38 trucks) and the Civic Centre (39 Vehicles)
  • Detailed EV fleet modelling proved that current incoming supply can meet the future EV charging requirements with smart load management, including preferential charging for critical vehicles.
  • Smaller capacity AC chargers recommended for vehicle parking bays with every car parking space having access to a charging port.
  • Fewer high-capacity chargers for emergency use.
  • Internal upgrades include new MSB, external distribution boards and extensive trenching and cabling.

Project Challenges

  • Worst- case charging scenarios, including emergency situations.
  • Gathering accurate information on vehicle fleets, vehicle using and milage.
  • Specific vehicle parking spaces limiting flexibility and electrical infrastructure design.
