An electric vehicle patent filed by Ford in 2021 was recently made public.

It appears aimed at facilitating “pass-through” electric vehicle charging.

Pass-through charging could charge multiple EVs, ultimately off the same charger plug.

Electricity would daisy-chain from a host vehicle to its surrogate, passing through each one connected to the other.

To do so? Two charger outlet ports per vehicle instead of one.

The F-150 Lightning’s existing bidirectional equipment is supposedly capable of jump-starting a second EV.

Expanding this capability with pass-through charging, then, would seem to add versatility to spacing accommodations for vehicles parked around stationary EV charging service equipment. 

Could this allow the equivalent of siphoning gas from a rubber hose? Not quite, because the pass-through charging function would be controlled by a web-based application.
