Dual charge ports could allow electric trucks a lot of energy flexibility

Common Motors a short while ago submitted a patent application for a dual cost port set up that could help get the most out of Ultium battery process in the automaker’s electrical pickup vans.

GM has made a double-layer battery pack which is now getting employed in the GMC Hummer EV, and is slated for the forthcoming Chevrolet Silverado EV and GMC Sierra EV. The proposed setup could present far more versatility in how all those two layers are billed.

Utilizing a sequence of controllers and switches, as nicely as the pack’s created-in ability to work as two different packs in sequence or in parallel, the software describes diverse charging situations for the dual-layer automobiles.

For reference, in the GMC Hummer EV 12 battery modules are wired in series to make up one layer, which is functionally a separate battery pack. That layer is related in parallel to one more identical layer with the exact selection of modules. In the Hummer EV, that provides up to additional than 100 kwh of battery capability, with 800-volt charging to get gain of speedier 350-kw DC rapidly-charging components.

GM outlines that a person charging port could be configured to cost at 800 volts or 400 volts, even though the other port would be linked to the second layer of the pack and be constrained to 400V. The procedure could hook up them in collection, charging both the upper and decreased layers concurrently at 800V utilizing the initial port only. Or it could charge equally layers at 400 volts by connecting them in parallel.

A 3rd configuration would isolate the two levels, charging them one at a time, GM mentioned. Alternatively, the second port could be employed for charging extras at 400 volt even though the vehicle carries on to cost at 800 volts. That could allow for GM trucks to power resources or other gear though they cost. Ford has advertised its F-150 Lightning as a cellular electrical power resource, but it only has one particular cost port and consequently cannot do that.

GM also noted that, with the addition of one more switch, it would be feasible to up grade the 2nd cost port to 800 volts. An illustration submitted with the patent software demonstrates both ports side by side—a structure that probably will make much more sense for fleet motor vehicles getting charged at company garages than individual vehicles, which would most likely reward from a port on each individual side.

It’s unclear if GM will truly put dual cost ports into generation, but more vans with dual-layer battery packs are on the way. The Chevy Silverado EV and GMC Sierra EV are the two anticipated to strike the current market in 2023 as 2024 versions.
