GM Applies for Patent for EV with Two Charging Ports


You could fill a pot a lot more quickly with two taps, you know.

That may perhaps not sound like a great engineering insight that revolutionizes transportation in The usa. But it may possibly be the start off of a thing.

Common Motors has filed a patent application with an amazingly uncomplicated idea, but a single that is illustrative of the way automobiles are changing.

It is an EV with two plugs.

Lasers, Conveyor Belts, and Tear Gasoline: Vehicle Companies and Their Patents

1st, a quick take note on patents: Automakers are some of the most aggressive people of America’s patent program. They routinely file for patents they may possibly hardly ever use.

Tesla, not kidding you listed here, holds a patent for a laser windshield cleaning program. Toyota retains a patent for an in-vehicle fragrance system that can also dispense tear gas for self-protection. Ford holds a patent for a conveyer belt that brings items from the trunk to the entrance seat.

Even businesses that only believe about creating automobiles maintain patents for them. Google holds a patent for a hood sticky adequate to immobilize a human becoming. It is meant as a security product – if you hit a pedestrian with your automobile, they’d stick to the hood alternatively of bouncing off and obtaining a second set of accidents from hitting the road. But think about washing it following a push as a result of Louisiana in bug season.

An concept does not have to be excellent to make a patent. It just has to be novel. And carmakers routinely patent concepts they never execute.

GM’s Batteries are Previously Two Batteries

GM’s new technology of electric powered automobiles, like the GMC Hummer and Cadillac Lyriq, is crafted on a platform the automaker phone calls Ultium. Ultium is a single, skateboard-like device of batteries, motors, and suspension that suits beneath a car’s cabin.

Engineers can scale it up or down to build vehicles as big as the Chevy Silverado EV and as modest as (likely even lesser than) the Chevy Blazer EV. The style will underlay an complete technology of GM vehicles. It’s successful plenty of that even Honda ideas to use it for its first committed EV, the future Honda Prologue.

The way GM scales the battery up for larger sized cars is, primarily, to wire two of them together. The Hummer and Silverado the two use a two-layer battery. So why not cost them separately?

EV Voltage

Some electrical autos (EVs), these as Tesla items, use a 400-volt architecture. Some, like the Hyundai Ioniq 5 and Kia EV6, use an 800-volt set up. Electrical charging is sophisticated and not as straightforward as 800-volt batteries charging 2 times as speedy as 400-volt batteries. But the 800-volt units at this time on the marketplace do demand quicker than 400-volt EVs.

What would be even a lot quicker? Using both.

GM’s patent would let consumers charge the entire battery from a single 800-volt port, the entire battery from one particular 400-volt port, or half of it from 1 of each individual. The ports are bi-directional, so they could also be utilized to electrical power other EVs or equipment in the field.

Electrical Engineers Are the New Garage Tinkerers

The patent may perhaps by no means become a performing procedure. A lot of automaker patents by no means do. This could be just another drawing of a sticky hood.

But it illustrates something new about the motor vehicle market.

Engineers discovered to tease as a lot overall performance as attainable from the inside combustion engine as a result of a century of tinkering and striving wacky factors with fireplace.

A pair of charging cords (and a driver applying two charging stations at as soon as when automobiles line up for their switch) could not be the innovation that helps make EVs much easier for Us citizens to dwell with day-to-day. But electrical engineers are the new artistic thinkers who will reshape what our cars charge and do for us.
