GM apply for a patent for dual charging holes: support charging and discharging at the same time

If you fill a pool with water, the efficiency of using only one water pipe is average, but wouldn’t the efficiency of using two water pipes to fill water into it at the same time double?

In the same way, using a charging gun to charge the electric car is relatively slow, and if you use another charging gun, it will be faster!

Based on this idea, GM applied for a patent for dual charging holes.

In order to improve the charging flexibility and charging efficiency of electric vehicles, GM applied for this patent. By connecting to the charging holes of different battery packs, the car owner can freely choose to use 400V or 800V charging voltage, and of course, two charging holes can be used at the same time. 400V charging efficiency.

It is understood that this system is expected to cooperate with the Autonen electric platform developed by General Motors to bring more convenience to car owners.

Of course, this patent is not as simple as adding an extra charging port for the power battery, and it needs to be used in conjunction with GM’s brand-new Autonen platform.

The battery pack in the Altener platform is chemically reduced in cobalt metal content, the battery pack can be stacked vertically or horizontally, the installation method can be changed according to different body structures, and more battery pack options are available.

For example, the HUMMEREV (pure electric Hummer) from this platform, its battery pack is stacked in sequence with 12 battery modules as a layer, and finally achieves a total battery capacity of more than 100kWh.

The common single charging port on the market can only be connected to a single-layer battery pack, but through the configuration of dual charging holes, GM engineers can connect two charging holes to different layers of battery packs, further improving charging efficiency.

What’s more interesting is that the patent content shows that one of the 400V charging ports also has an output function, which means that the vehicle with dual charging ports can also help another vehicle when charging.
