EV Infrastructure Feasibility for Residential Stata Buildings

EV Charging

30 EV Charging Infrastructure Feasibility assessments for apartment buildings with up to 350 spaces, for facility/owners corporations.

Key Achievements:

  • Electrical assessment of existing infrastructure for EV charging capacity to meet immediate, medium and long term requirements.
  • Identification of low-risk connection points for EV infrastructure.
  • Recommendations and detailed costing estimations for additional electrical infrastructure, charging ratings, types and load management systems (LMS); with the long term aim of providing chargers to every car parking space; whilst minimising expensive electrical upgrades.

Project Scope

  • Feasibility assessment and preliminary design, strategy, and cost estimate for Electrical Vehicle Supply Equipment (EVSE).
  • Assessment of existing common or house electrical infrastructure by in-house engineers and electricians.
  • Recommendations for a staged approach to future EV charging infrastructure requirements.
  • Concept layout design for preliminary costing purposes.
  • CAPEX and OPEX.
  • Cost recovery methods.
  • Key financial impacts and peak demand assessment.
  • Carpark concept layouts.
  • Shared EV charging.
  • EV backbone and last mile connection for individual carpark spaces.
  • Risk identification and mitigation.
  • Report presentation to owners corporations.

Project Details

  • Over 30 apartment buildings sites assessed some with multiple common/house NMIs including up to 350 car spaces.
  • 7kw AC chargers, with load management systems, recommended for individual and some shared parking bays.
  • Fewer high-capacity chargers for shared use in visitor parks.

Project Challenges

  • Meeting future EV charging requirements whilst minimising electrical and grid supply upgrades required.
  • Limited existing electrical documentation and labelling on site.
  • Strata planning requirements and issues.
  • Stakeholder requirements unknown at the early stage.
  • Education, new technology isn’t well understood by stakeholders.
