Start AETREN BriefTechnical Centre · International project guidance
AETREN projects are qualified around vehicle use, dwell time, site capacity, controls, climate and destination compliance. This Technical Centre explains the decisions that need to be resolved before an exact charger platform is released into a project.
Core technical decisions
These are planning pathways, not blanket claims about every charger. Exact specifications remain tied to the selected platform and destination evidence.
Best suited to longer dwell times such as workplaces, hotels, apartments, mixed-use parking and overnight or destination charging. Final charger quantity and output depend on dwell time, user demand and the site's available electrical capacity.
Used where vehicles need materially shorter charging windows or operational turnaround. The correct output class depends on vehicle capability, utilisation, simultaneous demand, site power and thermal performance rather than headline kW alone.
AETREN treats backend compatibility as a model-specific requirement. OCPP version, backend independence, remote management, firmware behaviour and any vendor dependencies must be checked against the exact charger platform.
Dynamic load management can reduce the need to size every charger at full simultaneous demand. The design still requires a real site load assessment, charger behaviour rules and a clear interface with the local electrical design.
RFID, metering, contactless payment and billing are separate decisions. A project should define who charges, who pays, whether public access is required and what evidence or metering standard applies in the destination market.
High ambient temperature can reduce usable charger output. Apollo does not use a generic 'GCC suitable' claim: the selected model needs an operating-temperature range and, where relevant, a thermal derating curve or table.
AC or DC?
A hotel guest parked overnight and a delivery fleet needing rapid turnaround should not be solved with the same charging logic.
Workplaces, apartments, mixed-use parking, hospitality, clubs and other sites where vehicles remain parked for meaningful periods.
Fleet, depot, public-facing and high-utilisation sites where charging time has direct operational value.
Project inputs
How long are vehicles normally parked? This is often the first decision separating destination AC from faster DC.
Passenger EVs, commercial vans, buses and operational fleets can have very different charging windows and onboard charging limits.
Existing maximum demand, transformer capacity and future electrical upgrades can materially change charger count and power class.
The project should decide how many vehicles need to charge at once and whether load sharing or priority rules are acceptable.
Private staff, hotel guests, residents, fleet drivers and public users create different RFID, billing, payment and support requirements.
Connector standards, certification, metering, electrical rules, climate and payment expectations vary by market and must be checked before release.
AETREN release control
A certificate or thermal claim from one charger family is not automatically carried across another enclosure, power class or configuration.
Model-specific certification and issued evidence
Destination electrical and connector requirements
Ambient-temperature performance and thermal derating
OCPP / backend interoperability and site-management scope
Metering, RFID, payment and communications configuration
Warranty, support, spares and project documentation
Supply-only boundary
Apollo can coordinate charger selection, available product evidence, configuration review, technical documentation and supply.
The appointed local electrical team remains responsible for site electrical design, protection, cabling, switchboards, earthing, grid / utility interfaces and installation unless expressly agreed otherwise.
Civil works, foundations, trenching, parking layout, bollards, line marking and accessibility requirements remain project-specific local works.
Commissioning responsibility, backend activation, payment onboarding and ongoing network support must be defined in the project scope rather than assumed.
APOLLO CITATION AUTHORITY · TECHNICAL REFERENCE
OCPP is treated as an exact-platform interoperability requirement, not a generic marketing claim. Charger certification, metering, connector, electrical and destination requirements remain model- and market-specific.
