Aluminum enclosures for EV charging
EV chargers live outdoors and run hot. We build the extruded aluminum housings, cabinets and battery enclosures those units need — IP-rated, EMC-aware and cooled where the power module demands it.
What an EV charger enclosure has to do
Protect electronics from weather, keep EMC contained, and move heat from the power stage — often in one extruded section.
An EV charger enclosure sits beside a road or in a car park, so it must resist rain, dust, UV and impact while staying cool enough for the rectifier and DC stage inside. Extruded aluminum suits this because the wall can carry both structure and heat: integral fins on the inside pull heat off the power module, while the same profile forms the gasket channel and mounting rails. For outdoor units we design to IP54 / IP65 class and confirm it on the finished part.
The cooling opportunity in EV charging is in the enclosure and power-stage housing, not in a separate heatsink product. High-power DC charging stacks IGBTs and SiC devices that need a thermal path; we provide that path as part of the housing, then add a liquid cold plate only where air cooling is not enough.
Enclosure types we build
From wallbox to cabinet, sized to your power level and site.
EV charger enclosure
Extruded housing with machined openings, gasket channels and internal fins for the power module.
See enclosures →Outdoor cabinet
Taller EV charger cabinet for DC fast charging, with IP-rated doors and cable management.
Battery enclosure
EV battery enclosure and pack housing, structurally stiff and thermally manageable for storage units.
IP class, size and thermal load are confirmed against your drawing and site spec — we give typical ranges on the enclosures page.
When to add a cold plate
Air cooling covers most AC chargers; liquid enters at high DC power.
For a 7–22 kW AC wallbox, integral extruded fins and natural convection are usually enough. Above roughly 50–100 kW DC, the power module's heat rises past what the enclosure alone can shed, and a liquid cold plate clamped to the devices becomes the economical choice. We design the two together — enclosure plus plate — so the coolant lines and mounting seats line up and the assembly stays leak-safe.

Questions buyers ask first
Short answers on build and compliance.
Do you make EV charger enclosures or heatsinks?
We make the aluminum enclosures and power-stage housings for EV chargers, with integral cooling where the spec needs it. For high-power DC units we add a liquid cold plate as part of the same assembly. We do not sell a separate consumer-style EV charger heatsink — the cooling lives in the housing we build.
What IP rating can you reach?
Typical outdoor charger enclosures are designed to IP54 or IP65 class, confirmed by gasket selection and verification on the finished part. The exact class depends on your door, seal and cable-entry design, so tell us the target and we design the extruded section around it.
Can you build the battery enclosure too?
Yes. An EV battery enclosure or pack housing is a structural extruded assembly we can machine, bend and weld, then anodize or powder coat. Stiffness and thermal management are designed against your pack layout; we confirm tolerances and finish to your print.
