GM Applies for Patent for EV with Two Charging Ports

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

That may not sound like a great engineering insight that revolutionizes transportation in America. But it might be the get started of a thing.

Typical Motors has filed a patent application with an unbelievably uncomplicated idea, but one that is illustrative of the way automobiles are transforming.

It’s an EV with two plugs.

Lasers, Conveyor Belts, and Tear Gas: Car Providers and Their Patents

Very first, a fast take note on patents: Automakers are some of the most aggressive customers of America’s patent system. They routinely file for patents they may possibly never ever use.

Tesla, not kidding you below, holds a patent for a laser windshield cleansing technique. Toyota holds a patent for an in-vehicle fragrance system that can also dispense tear fuel for self-protection. Ford holds a patent for a conveyer belt that delivers objects from the trunk to the front seat.

Even organizations that only think about constructing cars maintain patents for them. Google holds a patent for a hood sticky plenty of to immobilize a human currently being. It is intended as a basic safety product – if you hit a pedestrian with your auto, they’d adhere to the hood instead of bouncing off and getting a next established of injuries from hitting the road. But envision washing it following a push by means of Louisiana in bug season.

An plan doesn’t have to be great to receive a patent. It just has to be novel. And carmakers routinely patent suggestions they never ever execute.

GM’s Batteries are Currently Two Batteries

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

Engineers can scale it up or down to establish autos as massive as the Chevy Silverado EV and as small as (likely even more compact than) the Chevy Blazer EV. The style and design will underlay an full generation of GM automobiles. It is profitable ample that even Honda strategies to use it for its very first focused EV, the approaching Honda Prologue.

The way GM scales the battery up for larger vehicles is, effectively, to wire two of them with each other. The Hummer and Silverado both of those use a two-layer battery. So why not demand them separately?

EV Voltage

Some electrical autos (EVs), this kind of as Tesla merchandise, use a 400-volt architecture. Some, like the Hyundai Ioniq 5 and Kia EV6, use an 800-volt setup. Electrical charging is challenging and not as easy as 800-volt batteries charging two times as quickly as 400-volt batteries. But the 800-volt programs now on the market do charge faster than 400-volt EVs.

What would be even faster? Applying both equally.

GM’s patent would let customers cost the overall battery from a single 800-volt port, the full battery from a person 400-volt port, or fifty percent of it from a person of each individual. The ports are bi-directional, so they could also be made use of to electric power other EVs or machines in the industry.

Electrical Engineers Are the New Garage Tinkerers

The patent may under no circumstances turn out to be a performing process. A lot of automaker patents never do. This could be just an additional drawing of a sticky hood.

But it illustrates a thing new about the auto sector.

Engineers figured out to tease as much functionality as feasible from the inside combustion motor by means of a century of tinkering and striving wacky things with fire.

A pair of charging cords (and a driver working with two charging stations at after when cars and trucks line up for their transform) may not be the innovation that helps make EVs less difficult for Us residents to dwell with day-to-day. But electrical engineers are the new creative thinkers who will reshape what our cars and trucks cost and do for us.
