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.
Impact
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.
