In China, electric vehicle chargers come to you. 

It's a fascinating concept being built by several companies for parking garages, removing the need to roam around in search of a plug-in, according to Electrek.

A video clip shared on the social platform X shows the boxy contraptions moving on roof rails. They drop a charge line when they reach the vehicle that needs a boost.

The story noted Li Auto and CGXi as companies leading the development of these types of systems. In the U.S., a group of firms and designers helped to bring a unique parking garage to fruition at Lume Apartments in Menlo Park, California. An automated parking process transports EVs to charging stalls and then parks them after they are recharged. A robotic arm places a cable in the EV to fill the battery, according to San Francisco's Heller Manus Architects, one of the firms that helped with the project. 

The goal is to bring ease to the EV experience in sometimes crowded environments where public ports can come at a premium. That's why charging at home is a value. EV owners can save hundreds of dollars a year by plugging in at their house. It's far cheaper than gas, and even a value when compared to public stations that charge fees, per a cost breakdown from experts at Qmerit. 

The Chinese system arrives to drop a line automatically, with no app required to trigger the service. The design saved money by eliminating the need to wire a connector for each spot. It's all built through the roof-hung rail line. The system's power supply is limited to a Level 2 speed, according to Electrek. 

When it comes to chargers, a standard wall outlet — or Level 1 — is the slowest option and often takes more than 40 hours to fully charge an EV. Level 2 chargers are a middle-ground option, fully powering a battery in one to eight hours, depending on pack type and other factors. Public stations with DC fast chargers can provide 80% battery life in 20 to 40 minutes, Qmerit reported. But stall operators charge fees, which is part of the reason powering up at home is cheaper.

Electrek detailed some other unique overhead tech that's on the way to ease public charging. Stateside, an alliance of automakers is working on a project dubbed Ionna, which is designed to add 30,000 ports to America's roadways by 2030.

Another idea offered by experts at EnergySage is to leverage the country's robust campground network, which is already lined with reliable electric hookups, to offer charging opportunities for long-distance travelers even in remote areas. 

Unique options in parking garages could greatly reduce searching and line-waiting that's often needed to secure a recharge. 

"The overhead rail charging robot is the kind of practical, unsexy innovation that China excels at," Lambert wrote.
