In a bid to become a major player in the global EV space, Ford has filed an interesting patent with the USPTO for a huge, roof-mounted backup battery pack that can charge the primary high-voltage – its electric vehicle’s voltage battery, which increases the vehicle’s range when driving through areas where no electric vehicle charger is available. If installed, this would enable future electric Ford vehicles to travel greater distances without plugging in an external energy source.
Ford has already unveiled its all-electric F-150 Lightning, Mustang Mach-E, and E-Transit models, which are getting quite a bit of attention. The automaker is also developing a number of other models. Beyond that, Ford is working on several projects to ensure more support for its EV owners. One of them is a backup battery pack mounted on the roof. The Lightning Owners Forum posted the news along with a patent image showing a sketch of a Bronco-like SUV with a roof rack that houses a large box similar to a traditional roof box. A charging cable sticks out from the back of the box, making it look more or less like a spare battery that an EV could use to charge its main battery.

According to reports, the patent application said that when electric vehicle owners go on a trip, the supply of electric vehicle chargers is insufficient, and a backup battery can be installed. Furthermore, it can be unloaded at home, where the owner installed an EV charger to recharge the main high-voltage pack. This is more or less similar to using a power bank to charge your smartphone. Only in this case, the volume of the mobile power supply is much larger, and the charging device is the original battery pack of the electric vehicle.
The automaker claims that the roof-mounted spare batteries have air ducts on both sides of the case to improve battery cooling, and they can be fitted with remotely operated valves that can be closed to keep out water or sand. casing and possible damage to the battery. The patent filing images also show that the enclosure includes a lid and a tray lined with polyurethane foam to help manage thermal energy levels inside the enclosure and keep its interior relatively cool.
