Hyundai Files Patent for a Different Kind of EV Battery Layout

Hyundai has submitted a patent filing that outlines an alternative way to mount battery packs in electric vehicles built on a traditional body-on-frame chassis. Rather than treating the battery as a single sealed slab tucked beneath the cabin, the proposed design distributes pack elements in relation to the separate frame structure that sits under the body.

The idea addresses a long-standing tension between body-on-frame platforms, which remain common for trucks and rugged SUVs, and the flat, low-mounted battery layouts that most electric cars rely on. By rethinking how cells and modules are arranged around a separate frame, Hyundai appears to be exploring how electrification could fit into vehicles that are not built like conventional passenger EVs.

As with any patent, this is a filing rather than a production announcement, and Hyundai has not confirmed whether the concept will reach a showroom model. The document nonetheless signals that the company is weighing how its larger, frame-based vehicles could eventually go electric without abandoning their structural approach.

Additional details from the filing, including any specific claims about the battery mounting method, remain limited in the available source material.
