Twin cost ports may enable electrical vehicles lots of vitality flexibility

Normal Motors lately filed a patent utility for a twin cost port setup that might assist get probably the most out of Ultium battery system within the automaker’s electrical pickup vehicles.

GM has developed a double-layer battery pack that is already getting used within the GMC Hummer EV, and is slated for the forthcoming Chevrolet Silverado EV and GMC Sierra EV. The proposed setup may present extra flexibility in how these two layers are charged.

Utilizing a collection of controllers and switches, in addition to the pack’s built-in skill to function as two completely different packs in collection or in parallel, the appliance describes completely different charging eventualities for the dual-layer autos.

For reference, within the GMC Hummer EV 12 battery modules are wired in collection to make up one layer, which is functionally a separate battery pack. That layer is linked in parallel to a different similar layer with the identical variety of modules. Within the Hummer EV, that provides as much as greater than 100 kwh of battery capability, with 800-volt charging to reap the benefits of speedier 350-kw DC fast-charging {hardware}.

GM outlines that one charging port may very well be configured to cost at 800 volts or 400 volts, whereas the opposite port can be linked to the second layer of the pack and be restricted to 400V. The system may join them in collection, charging each the higher and decrease layers concurrently at 800V utilizing the primary port solely. Or it may cost each layers at 400 volts by connecting them in parallel.

A 3rd configuration would isolate the 2 layers, charging them one after the other, GM famous. Alternatively, the second port may very well be used for charging equipment at 400 volt whereas the automobile continues to cost at 800 volts. That might enable GM vehicles to energy instruments or different gear whereas they cost. Ford has marketed its F-150 Lightning as a cell energy supply, however it solely has one cost port and thus cannot do this.

GM additionally famous that, with the addition of one other swap, it might be attainable to improve the second cost port to 800 volts. An illustration submitted with the patent utility reveals each ports aspect by aspect—a format that in all probability makes extra sense for fleet autos being charged at firm garages than private autos, which might doubtless profit from a port on both sides.

It is unclear if GM will truly put twin cost ports into manufacturing, however extra vehicles with dual-layer battery packs are on the best way. The Chevy Silverado EV and GMC Sierra EV are each anticipated to hit the market in 2023 as 2024 fashions.
