CTOnews.com, June 10 / PRNewswire-Asianet /-- Ford has applied for an interesting patent to install an external battery on the roof of an electric vehicle to charge the main battery pack in an area where there is no charging pile.

Ford's filing with the U.S. Patent and Trademark Office (USPTO) shows a Bronco-like SUV with a luggage rack on the roof and something similar to an ordinary roof suitcase. However, a charging cord protrudes from the back of the box, in which there is a spare battery.

Ford said in its patent application that the spare battery can be installed when preparing for a trip to an area where the charging posts are scarce and unloaded after returning home, and the car owner can use the electric car charger installed at home to charge the battery. Therefore, it can be seen as a large mobile portable battery for charging electric vehicles.

"the backup battery pack includes multiple battery modules and a connection port, and a cable can be used to electrically connect the backup battery pack to the electric vehicle by plugging into the connection port of the backup battery pack and the charging port of the electric vehicle," the patent application said. " In addition, Ford said the roof backup batteries have air pipes on both sides of the shell to improve the heat dissipation of the cells, and they can be equipped with remotely operated valves that can be closed to prevent water, cold or sand from entering the shell and may damage the battery.

In addition, the battery also contains a control module, which can be connected with the communication module of the vehicle to facilitate the owner to control the battery in the vehicle.

This is a very creative patent that can solve the problem of charging without a charging post when using electric vehicles off-road, but CTOnews.com found a problem with this solution: weight. As we all know, lithium-ion batteries are quite heavy, and putting them on the roof will cause the center of gravity of the vehicle to get higher and capsize easily at high speed, so this is not a small problem.
