Hyundai's New Patent Rethinks EV Batteries for Body-on-Frame Trucks

Hyundai has filed a patent for a fresh approach to packing batteries into body-on-frame vehicles, the rugged architecture used by pickup trucks and large SUVs. Instead of treating the battery as one big slab bolted underneath, the design arranges cells in a way that fits the frame’s structure more naturally. The patent describes how this layout could solve a long-standing tension: body-on-frame platforms are strong and tow-friendly, but their shape makes it awkward to house enough battery capacity without compromising ground clearance or cabin space.

The idea is essentially modular. By positioning battery modules within the frame rather than as a single under-floor pack, Hyundai’s patent suggests the vehicle could carry usable energy while keeping the chassis traits that truck buyers expect, such as durability and off-road capability. It is a technical filing, so it does not guarantee a production vehicle, but it points to how the company is thinking about electrifying the heavier end of its lineup.

Hyundai has not issued a public statement tied to this patent, and the filing itself does not include a company quote. That means the details remain speculative until Hyundai confirms how, or whether, the concept reaches showrooms. For now, the patent is best read as an engineering signal: the automaker is exploring ways to make electric body-on-frame trucks and SUVs viable without abandoning the formula that makes them useful.
