Rivian Level 2 EV Charger Pedestal

Rivian’s Level 2 charger pedestal is an outdoor mounting and cable-management system designed to support one- or two-charger wallbox configurations, combining structural support, service access, and a cleaner field-ready charging experience around an existing charger platform.

The Challenge:

Engineering the system around the charger

This was not a charger development program in the usual sense. The charger already existed. The challenge was to engineer the pedestal system around it

Pro Max first engaged Inertia to support the industrial design refinement and mechanical engineering of a production-intent pedestal architecture for Rivian’s Level 2 wallbox charger. The system needed to support both single- and dual-charger configurations, integrate an off-the-shelf cable retractor, conceal hardware wherever possible, and maintain a clean architectural presence while still being practical to install and service.

When the accessory is actually the hard part

The requirements became more demanding as they stacked up. The pedestal had to withstand a 300 lbf horizontal load at its tallest point, accommodate conduit routing through the structure, align with Type 3S enclosure intent under UL 50E guidance, manage water intrusion and drainage, and allow the retractor to be serviced by removing only the top cap. It also had to move on an aggressive schedule toward prototype release

The real work was not simply to design a pedestal that looked resolved. It was to reconcile structural performance, enclosure logic, serviceability, cable management, manufacturability, and schedule inside one coherent system.

The Approach:

Architecture before detail

Inertia approached the work as a systems architecture problem rather than a housing exercise.

The team began by developing the pedestal architecture around a central structural body that could support both the single- and dual-charger variants. That meant studying how charger faces, aesthetic faces, top-cap facets, rear structures, and the retractor housing could work together as a modular system instead of creating separate pedestal designs for each configuration.

Integrating the retractor without breaking the product

A major part of the work centered on integrating the cable retractor without letting it distort the rest of the product. The design had to maintain the same pedestal body dimensions across both single- and dual-mount versions while housing the cable-management system and preserving service access. Inertia worked through the geometry, packaging, access strategy, and top-cap construction needed to make that possible.

From concept geometry to production-intent mechanics

From there, the work moved into detailed mechanical engineering. Inertia developed the base structure, brackets, caps, extrusions, retractor interfaces, charger mounting details, and other production-intent parts needed to turn the concept into a buildable assembly. Structural analysis was performed across key load conditions, and the results informed changes to the base and support geometry where additional stiffness or reinforcement was needed.

Controlling fit before it became a manufacturing problem

The team also carried out a significant tolerance stack-up and GD&T effort across the assembly. That mattered because the pedestal relied on several interdependent manufactured parts, including extrusions, weldments, cast or molded elements, and formed covers. Without disciplined dimensional control, the likely outcome would have been visible gaps, interference, fit issues, or assembly workarounds discovered too late.

Prototype-oriented validation was used to reduce that risk before release. Fit checks and physical reviews helped verify assembly relationships, service access, and gap conditions while drawings and CAD were being finalized. In parallel, Inertia incorporated manufacturability feedback on items like the extrusion strategy, casting details, hardware approach, and assembly sequence so the design would hold up beyond the screen.

The Outcome:

A coherent pedestal architecture ready for prototype release

The result was a production-intent pedestal design package that translated Rivian’s requirements into a coherent mechanical system.

By the end of the program, the pedestal architecture had been resolved across structural support, charger mounting, retractor integration, service access, dimensional control, and manufacturability. The design supported both single- and dual-charger configurations within a shared body architecture, which helped preserve modularity without forcing a ground-up redesign for each variant.

More than a clean form

Just as importantly, the project moved beyond concept-level confidence. The pedestal had been engineered against real load and enclosure requirements, the dimensional relationships across the assembly had been worked through, and the design package had been prepared for prototype release with production intent in mind

This is the kind of program that can look deceptively simple from the outside. In practice, it required the coordination of enclosure design, structural engineering, cable-management integration, service logic, and manufacturing detail inside a product that still needed to feel clean and straightforward in the field. Inertia’s role was to make that complexity behave.
