Overall scheme of patent application for improving charging efficiency of 400V voltage with double charging holes for electric vehicles

Recently, in order to improve the charging flexibility and efficiency of electric vehicles, General Motors applied for a patent for dual charging holes. By connecting the charging holes of different battery packs, the owner can freely choose to use the charging voltage of 400V or 800V V. Of course, two charging holes can also use the charging efficiency of 400V at the same time. This system is expected to cooperate with the Autodyne electric platform developed by General Motors, which will bring more charging convenience to car owners.

The battery pack in the Autron platform reduces the cobalt metal content in chemical composition; Battery packs can be stacked vertically or horizontally, and the installation mode can be changed according to different body structures, providing more battery pack options. Take the Hummer EV owned by General Motors as an example. Under the Otneng platform, its battery pack is stacked in turn with 12 battery modules as one layer, and finally the total battery capacity exceeds 100 kWh.

It turns out that only a single battery pack can be connected under the configuration of a single charging hole; However, through the configuration of double charging holes, GM engineers can connect the two charging holes with different layers of battery packs, further improving the charging efficiency. Not only that, the patent content also reveals that one of the 400V charging holes will have an output function, which means that a vehicle with two charging holes can also charge another vehicle at the same time.
