GM Patents Twin Cost Ports To Cut back Charging Time, Enhance Flexibility


One of many causes Common Motors designed the batteries for its newest EVs as double-layer packs (that may be switched from being linked in collection to parallel) could have been to cost each halves on the identical time from two separate chargers. Such a battery pack is already in use within the GMC Hummer EV, however comparable ones can even energy the upcoming GMC Sierra EV and Chevrolet Silverado EV.

The automotive big lately utilized for a patent on twin charging ports for its EVs. However except for charging the 2 sides of the pack independently, and thus theoretically chopping cost instances considerably, GM additionally presents extra use circumstances for the twin ports, like charging one other EV whereas the one with the dual port is itself being juiced up – this is able to be helpful when there’s just one charger, and the GM EV would supply a port for the opposite electrical automobile to attract from.

A number of different conditions had been additionally talked about, like having one port cost the battery pack, whereas the opposite would energy instruments and tools that you may plug into the automobile. Based mostly on what we collect studying the patent software, it appears like GM is trying to make one port quick charging-capable, at as much as 350 kW, whereas the opposite will simply cost the automobile at slower charges of as much as 22 kW.

This is able to not be one thing out of the peculiar, although, since there’s already a automobile in manufacturing right this moment, the Porsche Taycan, which has two charging ports of which just one is quick charging-enabled. GM’s patent software does say that for its twin port resolution, you’ll be capable of pay to have the second port upgraded to 800 volts, presumably with a purpose to cost either side of the pack at fast charges.

What units this twin port resolution aside from the one used within the Taycan is that not like on the Porsche, which has the ports one on all sides, the GM method is to have them on the identical aspect, one subsequent to the opposite. This stems from the truth that within the Taycan they weren’t designed for use on the identical time.
