Destination country and local electrical standard
AETREN · PROJECT AUTHORITY CENTRE
Move from product interest to a controlled project specification.
Plan EV charging as site infrastructure: vehicle demand, dwell time, electrical capacity, charger power, load management, OCPP/backend, protection, networking, civil interfaces and destination evidence must work as one system.
NZ remains excluded from the AETREN public product pathway until exact products and certification are approved.
01 · PROJECT INPUTS
Define the conditions before the exact system is released.
These inputs are deliberately upstream of model selection so the product does not dictate the brief.
Site type, vehicle mix, fleet/public use and parking dwell time
Daily energy requirement and simultaneous charging assumptions
Available electrical capacity, transformer/switchboard context and future growth
AC/DC charger mix, connector standard and cable-management strategy
Load balancing / dynamic load management / energy-management requirement
OCPP/backend, payment, RFID, app and data/network ownership
Civil works, bollards, signage, accessibility, weather exposure and service access
02 · EVIDENCE CONTROL
Keep project claims attached to what the evidence actually proves.
Generic declarations, outdated catalogues or unrelated certificates should not be carried into a project as exact-system evidence.
Exact-model destination electrical/safety certification
OCPP version and independent interoperability evidence where claimed
Metering / payment compliance where relevant
IP/IK, temperature, humidity and environmental performance
Load-management architecture and supported communication protocols
Warranty, spare modules, service tooling and firmware/update pathway
Exact connector/cable evidence and destination compatibility
03 · CAD / DRAWING REGISTER
Planning references are not exact-system construction drawings.
Every drawing/model status stays visible so consultants know what can be used now and what only exists after configuration or project-specific design.
| Resource | Status | Purpose |
|---|---|---|
| Charging-site concept / planning layout | Public planning | Early scope, interface and consultant coordination only. |
| Generic technical reference / typical detail | Public planning | Explains system logic without representing an exact supplied configuration. |
| Exact-system GA / dimensional drawing | Exact-system | Issued only after the quoted system/configuration is known. |
| Native CAD / DWG / DXF | Verify availability | Availability and revision must be confirmed against the exact supplied system. |
| BIM / Revit / IFC object | Verify availability | Only described as BIM where a genuine verified native model exists. |
| Foundation / fixing / setting-out drawing | Project-specific | Depends on site/building conditions, local engineering and the selected system. |
| Services / electrical / controls interface | Project-specific | Coordinates the supplied system with local power, data, water, drainage or controls. |
04 · SPECIFICATION STARTER
Write the project around performance, interfaces and evidence.
These clauses are a project-planning structure, not a substitute for local professional specifications or exact-system documentation.
Charging use case and service level
AC/DC power architecture
Vehicle/connector compatibility
Electrical capacity and diversity assumptions
Dynamic load management / site controls
Backend/OCPP/payment/network requirements
Environmental and impact protection
Civil/foundation/cable-routing interfaces
Evidence, commissioning, warranty and service requirements
05 · TENDER / RFP SCHEDULE
Ask bidders for the same controlled information.
A consistent schedule makes technical comparison easier and reduces hidden assumptions.
Site single-line / electrical information
Parking and charger layout
Vehicle/use profile
Charger power and quantity schedule
Backend/payment/network specification
Load-management requirement
Environmental/impact requirements
Certification/document schedule
Commissioning/service/warranty scope
06 · OPERATIONS & HANDOVER
Specify how the system will be maintained after delivery.
Maintenance, spares, records and inspection should be defined before purchase, especially for remote or high-use projects.
Charger availability and fault log
Cable/connector inspection
Enclosure and impact-protection inspection
Backend/OCPP connectivity monitoring
Meter/payment reconciliation where applicable
Firmware and cybersecurity/update control
Critical spare modules and service response
Periodic capacity review as fleet/usage grows
AUTHORITY GUIDES
Go deeper on the decisions that usually control the project.
These guides sit below the owner page and above exact product selection, so search, specification and project planning all point to the same technical logic.
AC vs DC EV charging for commercial projects.
Compare AC and DC commercial EV charging by dwell time, daily energy, electrical capacity, vehicle mix, turnover, load management and operating model.
