Tesla patent reveals dual-battery system for trailer-mounted range extender

Tesla has patented a dual-battery system that could allow an auxiliary battery pack, potentially housed in a trailer, to extend a vehicle's range. This development suggests Tesla is still working on range-extender technology despite canceling a similar product for the Cybertruck. For owners, this could eventually offer a flexible solution for significantly increasing driving distance on long trips or when towing.
