Hyundai patent reveals new body-on-frame EV battery setup

Hyundai has filed a patent revealing a novel body-on-frame electric vehicle (EV) battery configuration, signalling a potential shift in EV design philosophy. Unlike the prevalent skateboard chassis, which integrates the battery pack into the floor of a unibody structure, Hyundai’s approach involves mounting the battery within a separate frame beneath the vehicle’s body. This design could offer enhanced modularity and ease of repair, marking a departure from current industry standards. The patent details a structural frame that supports the battery pack independently from the vehicle’s body, allowing for easier replacement or upgrading of battery modules. This setup may also improve crash safety by isolating the battery from impact forces transmitted through the body. Additionally, the body-on-frame architecture could facilitate the development of multiple vehicle types using a common battery frame, potentially reducing production costs and increasing flexibility. Industry experts have noted that while body-on-frame designs are common in traditional internal combustion engine vehicles, especially trucks and SUVs, their application in EVs has been limited. Hyundai’s innovation might bridge the gap between rugged vehicle construction and electric powertrains, appealing to customers who prioritise durability and off-road capability. The company has yet to confirm whether this patent will translate into a production model, but the concept reflects ongoing experimentation within the EV sector. If realised, Hyundai’s battery frame design could influence future EV manufacturing by enabling easier battery maintenance and possibly extending vehicle lifespans. It may also open new avenues for vehicle customisation and modular upgrades, addressing some of the challenges faced by current integrated battery systems. Observers will be keen to see how this technology develops and whether it gains traction among other manufacturers seeking alternative EV architectures.
