GM Patents a Daisy-Chain EV Charger That Lets One Station Power Several Cars

General Motors has filed a patent for a new type of charging station that lets multiple electric vehicles share a single power source. The system works like a daisy chain: instead of each car needing its own dedicated charger, the first vehicle connects to the grid and then passes electricity along to the next car in line, and so on.

The patent aims to make charging more practical in places where installing separate high-power chargers for every parking spot would be too expensive or logistically difficult. By linking cars together, a single charging point could serve several vehicles, potentially lowering costs for businesses or property owners who want to offer EV charging.

GM hasn’t publicly commented on the patent, but the filing shows the company is exploring ways to simplify EV infrastructure. If it reaches production, this daisy-chain approach could be especially useful for fleet operators or residential complexes where many EVs need to charge overnight. The patent doesn’t guarantee a product, but it signals GM’s interest in making charging more accessible as EV adoption grows.
