Ford Innovates Easier Repair for Electric Vehicle Battery Packs
Ford is exploring ways to simplify the repair process for electric vehicle battery packs, especially as their cooling systems become more advanced. A recent patent filing reveals the company’s efforts in this area.
The patent, published by the United States Patent and Trademark Office (USPTO) on December 12, 2024, showcases Ford’s concept of replacing battery modules without the need to remove the entire pack from the vehicle. This innovation has the potential to lower repair costs and promote sustainability by enabling the rehabilitation of packs with new modules instead of full replacements.

Ford’s design retains the standard layout of a battery pack mounted beneath the vehicle floor, comprising multiple modules with numerous battery cells. The inclusion of electrical terminals with removable caps and spring-loaded connectors facilitates the easy removal of modules as required.
The patent filing also introduces the concept of immersion cooling, where battery components are directly cooled by a non-conductive fluid to prevent electrical shorts. This cooling method represents a departure from traditional liquid cooling systems used in most modern EVs, which typically cool the components externally.

While Ford explores immersion cooling, other automakers like Mercedes-Benz are considering air-cooling alternatives. General Motors and Canoo are also investigating different cell and module configurations to enhance cooling efficiency and structural integration.
Immersive cooling systems, such as those detailed by Rimac, offer advanced thermal conditioning for individual cells. This technology, if brought to the mass market, could position Ford ahead of competitors like Tesla in the electric vehicle industry.
