While we expect to find a single fuel door in a car, this is not always the case, and vehicles like the 1970’s Chevrolet 1500 actually had two fuel tanks and two filler ports. Now, GM may be, to some extent, bringing that idea into the electric age.
The company has filed a patent for an electric vehicle with multiple charging ports that could give owners more freedom of choice when charging. Its patent, entitled “Dual Charge Ports on a Mobile Platform in an Adaptive Fast-Charging of Multi-Pack Battery System” was first discovered by Green Car Reports.
The system can work with the Ultium platform, which has 12 modules wired in series to create a “battery pack”. It is connected in parallel with a second, almost identical pack with the same number of modules. Through a series of controllers and switches, this patent offers to configure them to charge one at a time or simultaneously via dual charging ports.

This will give owners the freedom to use an 800V charger for one module and a 400V charger for another or to charge at 400V simultaneously. And the flow of electricity will not be one-way.
One car can charge at 800V while simultaneously charging another car at 400V, allowing multiple vehicles to be charged at once, which can be effective in one worksheet. A work site will also be helpful when charging a car and using it as a power supply for equipment and other electrical equipment.
Although the patent application drawings show two plugs next to each other, they can be placed on either side of the vehicle to facilitate parking at the charging station. It is unknown at this time what he will do after leaving the post.
