Pittsburgh – November 10, 2026 -- A Massachusetts inventor is offering THE FIFTH WHEEL, an adapter that generates electricity while an electric vehicle is moving, for licensing or sale to manufacturers and marketers.
Adapter charges the auxiliary battery while the vehicle is in motion
The inventor, from Canton, Mass., designed the device as an auxiliary battery-charging feature for electric vehicles. It is intended to remove the need to stop and recharge at home or at a public charging station, which the inventor says increases efficiency and avoids delays. The stated goal is to let drivers cover longer distances without recharging stops.
Design targets new-production vehicles and existing EV owners
The inventor describes the design as easy to employ and aimed at two groups: manufacturers of new-production electric cars and light trucks, and owners of existing electric vehicles. No performance data, such as charging output or range gain, was provided.
Prototype and technical drawings are available on request
A prototype model and technical drawings can be requested. The original design was submitted to the Boston sales office of InventHelp, which is handling the submission under reference Dept. 25-BKC-1015. The invention is currently available for licensing or sale to manufacturers or marketers.
