Hyundai patents ladder‑frame EV truck
- Hyundai’s newly issued U.S. patent shows a body-on-frame EV layout that mounts the battery inside the frame rails for tougher trucks and SUVs. - The patent, No. 12,620,663, was issued May 5 and describes a pack that overlaps inward from the side members to protect cells. - It matters because Hyundai is building a midsize pickup around 2028, where towing, clearance, and battery durability still limit EV trucks.
Electric pickup trucks have a packaging problem. The easiest EV layout is a big flat battery under the floor, but that setup gets awkward when the vehicle also needs ground clearance, axle travel, towing strength, and underbody protection. That is why Hyundai’s new U.S. patent matters. It shows a body-on-frame EV architecture that tries to solve the truck version of the battery problem instead of just stretching a crossover-style skateboard. ### What did Hyundai actually patent? The patent is called “Battery Pack Mounting Structure for Vehicle,” and it was issued in the United States on May 5, 2026 as patent No. 12,620,663. The core idea is simple: instead of hanging one big pack below the cabin like most EVs do, Hyundai places the battery within the ladder-frame structure, with the pack overlapping inward from the frame side members and enclosed by a protective case.

That matters off-road and under tow, where the chassis gets worked hard in ways a low, flat EV floor does not always love. Hyundai’s patent is basically trying to keep the truck virtues of a body-on-frame vehicle while still making room for a large battery. (electrek.co) ### Why not just use the normal EV “skateboard”? Because the normal skateboard is great for crossovers, but trucks ask for different compromises. A low battery helps handling, but it can hurt breakover angle, underbody protection, and suspension packaging. In a work truck or trail truck, the battery is also the expensive thing you really do not want exposed to rocks, flex, or impacts. Hyundai’s layout tries to tuck the pack into the structure itself, which could protect it better without giving up cabin or cargo space. (electrek.co) ### Does this mean a Hyundai electric pickup is confirmed? No — a patent is not a product announcement. But the timing is not random. Hyundai has already been talking publicly about a more rugged midsize pickup for the U.S. market, and executives have pointed toward body-on-frame construction as the competitive direction. Separate reporting this year put that pickup around 2028, with an SUV on the same architecture expected before 2030. (electrek.co) ### Is Hyundai betting only on a pure EV? Probably not. The interesting part is that Hyundai’s broader truck plan sounds flexible. Recent reporting around the upcoming pickup says the platform under consideration could support EV, hybrid, internal-combustion, and extended-range electric versions. That suggests Hyundai is treating the frame as a multipurpose truck base first, then deciding how electric each model should be. That is a pretty pragmatic read of where truck demand is right now.

Bigger batteries help range and towing, but they also add weight, and weight is brutal on efficiency, payload, brakes, and tire wear. If Hyundai can package the pack as part of the frame and still keep the truck tough, it could end up with a cleaner answer to a problem everyone in this segment is still wrestling with. (electrek.co) That is the real point of the patent. ### What is the catch? The catch is that patents are cheap compared with production. Hyundai still has to prove thermal management, crash performance, repairability, charging layout, and cost. A battery integrated deep into the frame can be clever, but it also risks becoming harder to service if something goes wrong. The truck market is unforgiving about that stuff. (autoblog.com) ### Bottom line? This patent does not prove Hyundai has cracked the electric truck formula. But it does show Hyundai is working on the right problem — how to build an EV that still behaves like a real truck. If the company can turn this frame-integrated battery idea into a production pickup by 2028, it will have something more interesting than just another electric lifestyle truck.
