Two products.
One architecture.

One architecture across residential and commercial static pads.

— The solution

Meet SIGMA-WPT.

Resonant wireless transfer with bidirectional, software-defined control. The pad sleeps in the ground until your vehicle is above it.

— Target applications

Wherever the next mile
begins.

Whether it's a sedan at home or a forklift on third shift — the SIGMA pad is the same platform.

01 · Static charging

Park & forget.

Urban car-sharing, residential and commercial garages — drive over the pad, walk away.

02 · Fleets & logistics

No cable. No downtime.

AGVs, warehouse robotics, hospital and campus mobility — top up at every stop without connector wear.

— About SIGMA Easy Charge

We build the part
you never touch.

SIGMA Easy Charge is a power-electronics company spun out of the University of Porto in 2023. We design wireless inductive chargers that disappear into floors, parking lots and roads.

The cable is the friction. The plug is the failure point. Apps, RFID cards, broken connectors, mis-aligned cables in the rain — none of it should exist when vehicles park themselves.

So we removed all of it.

One platform scales from a driveway pad to a commercial depot.

We're a focused team in Porto at UPTEC. We ship hardware. We answer the phone.
