EV Charging Enclosures for AC Terminals and DC Power Cabinets
FN makes enclosure bodies for AC charging terminals, DC power cabinets and station auxiliaries. Before fabrication, review the display and payment cutouts, module layout, cable handling, cooling interfaces, foundation and service access against the charger design and site drawings.
01 / SYSTEM POSITION
The enclosure role depends on the charger architecture
A public-facing AC terminal, a DC power-module cabinet and a station auxiliary cabinet need different cable routes, thermal openings, mounting and maintenance access. They are separate enclosure projects.

02 / TYPICAL CONFIGURATIONS
Three enclosure routes for AC, DC and site equipment
An AC public terminal, a DC fast-charging power cabinet and a site auxiliary cabinet have different public, thermal, cable and service requirements.
AC Charging Terminal Housing
Public-facing pedestal or wall-mounted bodies around controls, communication and charging interfaces.
- Display and control cutouts
- Cable exit and holster position
- Public contact and lock details
- Wall, pedestal or base mounting
DC Fast-Charging Power Cabinet
Larger cabinets around power modules, cooling hardware and serviceable equipment zones.
- Module lineup and heat load
- Cooling interface and service side
- Heavy-device support
- Door and replacement path
Site Auxiliary / Distribution Cabinet
Separate station cabinets for auxiliary power, communication or distribution equipment.
- Equipment and cable layout
- Foundation or pad interface
- Site access and security
- Responsibility separate from charger terminal
03 / FAILURE MODES
Public-Site and Service Failures That Change the Charger Body
Public contact, display and payment cutouts, cable handling, heat, foundations and module replacement all affect the body. A broad weatherproof claim does not define these interfaces.
Display or payment cutout uses nominal dimensions
Consequence: Visible misalignment, sealing conflict or field rework.
Mechanical decision: Cutout, studs, rear depth, support and front-panel geometry.
Required input: Exact vendor drawing, bezel, hardware and service envelope.
Public impact and exposed fasteners are not reviewed
Consequence: Panels, locks or interfaces are vulnerable at the site.
Mechanical decision: Panel stiffness, hinge or lock design, fastener exposure and base geometry.
Required input: Site risk, security specification and impact-protection concept.
Charging cable and holster geometry is added late
Consequence: Cable strain, awkward handling or door conflict.
Mechanical decision: Exit, bracket or holster, bend space and panel reinforcement.
Required input: Cable or connector model, reach, weight and operating path.
Power-module heat is declared after layout
Consequence: Cooling openings, cabinet volume or service side changes.
Mechanical decision: Airflow hardware, module spacing and removable panels.
Required input: Module loss data, ambient and selected cooling concept.
Foundation and anchor plan is provisional
Consequence: Base, door orientation or site installation conflicts.
Mechanical decision: Plinth, anchors, leveling, lifting and site clearance.
Required input: Approved foundation or site drawing and structural responsibility.
Module replacement path is blocked
Consequence: Service requires removing unrelated panels or site equipment.
Mechanical decision: Door width, rails, removable panels and access aisle.
Required input: Replacement sequence, tool space and module weight.

Review question: Who accesses each compartment and from what side?
Release evidence: Access-control specification + maintenance sequence.
05 / CONFIGURATION ROUTES
Select the Enclosure Route From Charger Architecture and Public Exposure
A modified cabinet can work for stable interfaces; custom public terminals and serviceable DC cabinets need a coordinated body release.
Modified Standard Cabinet
Use when a known body fits a non-public auxiliary or power function and only controlled openings, plates or base features change.
- Fastest route for stable interfaces
- Approved modification drawings
- Confirm site and service constraints
Custom Charger Enclosure Body
Use for public-facing AC or DC equipment with project-specific display, cable, cooling, doors and base interfaces.
- Coordinated public, equipment and site review
- Custom panels and structure
- First-article CTQs from approved drawings
Repeat OEM Charger Platform
Use when one released architecture supports controlled power, display or branding variants across production batches.
- Master body and option matrix
- Revision-controlled interface variants
- Finish, hardware and batch evidence plan

10 / FAQ
EV Charging Enclosure FAQ
Questions specific to AC terminals, DC fast-charging cabinets and site auxiliary enclosure-body projects.
Does FN supply a complete EV charger?
This page covers enclosure bodies and approved mechanical interfaces. Power electronics, wiring, software, payment, communication, charging functions, commissioning and complete-charger certification remain with their responsible parties unless separately contracted and verified.
What is the minimum package needed for quotation?
Send the charger route, equipment or module layout, display and payment drawings, cable or connector data, heat and cooling inputs, foundation or site drawing, maintenance sequence, material and finish, quantity and date.
Can FN make display, payment and control cutouts?
FN can manufacture approved geometry and mounting provisions from exact vendor drawings. The selected device, sealing, wiring, software, payment and final functional validation remain with the responsible charger OEM.
How should charging cable and holster interfaces be reviewed?
Provide the exact cable and connector assembly, reach, weight, bend or strain limits, operating path and approved bracket or holster drawing.
What site information affects the base and doors?
Foundation and anchor pattern, leveling, lifting, bollards, curbs, adjacent chargers, vehicle exposure, pedestrian path, door swing and technician access can all change the body.
How are replaceable power modules accommodated?
Provide module size, weight, connectors, rail or support method, removal direction, tools and required service aisle. FN can manufacture the approved mechanical path; the OEM validates the service procedure.
Does the enclosure body guarantee final charger or site protection performance?
No. Installed modules, openings, cable interfaces, assembly, foundation, bollards, field work and complete-system verification determine final performance.
