[DigitalToday reporter Jinju Hong] Tesla is innovating how it installs Superchargers and sharply speeding up the expansion of electric-vehicle charging infrastructure.

On March 26 local time, EV outlet InsideEVs reported that Tesla recently introduced a new Supercharger system based on a "Folded Unit" (FU). The system delivers eight charging stalls and a power cabinet preassembled on a single steel base. Tesla's existing prefabricated Supercharger unit (PSU) installed four stalls on a concrete base and could transport up to 12 stalls at a time. The new folding unit expands in eight-stall blocks and significantly improves efficiency.

It also eliminates the need to install individual equipment on site, requiring only crane placement. This pre-fabrication approach improves both logistics and construction efficiency. Tesla said one truck can carry two folding units, allowing it to transport about 33 percent more charging stalls than before. It said installation costs fall about 20 percent and build time is cut by about half.

A hinge structure is a key feature. Units can be unfolded on site and repositioned to fit different spaces, increasing flexibility for installation conditions. All cables are also pre-wired at the factory to minimise on-site work.

Performance has also been upgraded. The system uses Tesla's latest V4 Supercharger, enabling up to 500 kW per stall, while the power cabinet supports up to 1.2 MW. That is about double the existing V3, which has a maximum of 250 kW, and reflects a change to meet growing demand for high-power charging.

Lucid Motors, Porsche and BMW, among others, now support higher charging speeds in their latest EV models, increasing the need for infrastructure upgrades.

Tesla's charging division said this is the first version of the system and development is expected to reach a third version as early as next quarter.

The industry views this change as a potential turning point that could alter how EV charging infrastructure is expanded, rather than a simple equipment upgrade. With installation speed and costs long cited as key bottlenecks, attention is on whether Tesla's factory-built charging-site strategy will spread across the broader market.
