Electric vehicles have the potential to become mobile power banks for our houses and worksites. But as more scenarios become viable, would two ports be better than one?
That appears to be something GM has either pondered, or saved for the future, with a recent patent
filing showing a setup that might get the most out of GM’s double-layer pack that’s already being used in the GMC Hummer EV and in the forthcoming Chevy Silverado EV and GMC Sierra EV.
GM outlines that one charging port could be configured to charge at 800V or 400V, while the other charge port would be connected to the other “pack” and only be 400V. It could connect them in series while charging both the upper and lower packs at the same time using 800V and the first port. Or it could use both ports to charge the upper and lower packs simultaneously at 400V, with the controller capable of selectively connecting them in parallel.
