— About SIGMA Easy ChargeWe build the part
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.
