EV Charger


To supply power to these vehicles, a device is needed that makes the electricity from the general grid compatible with the vehicle’s battery, while managing its consumption. This device is a charger that, for reasons of convenience and safety, must meet a number of technical requirements while at the same time being designed to supply the vehicles with comfort.

EV Charger

Designed to be installed (both indoors and outdoors) at private homes, communal blocks, workplaces and car parks.

Concept Design
eNext has been designed to simplify the charging process. We developed an autorization method via app that allows the user to start charging without any interaction with the charger.

In terms of the exterior design, we kept black and white as the core design colours while introducing curved lines and rounded shapes. The appropriate proportions and the perfect size, along with the piano black combined with matt white makes the eNext series the best choice to match any wall.

EV Charger

Designed to be installed in both public access environments (urban spaces, shopping centres, airports, road-side rest areas…) and private areas (companies with EV fleets, taxi ranks…) where vehicles need to be ready to continue their journey in less than half an hour.

Concept Design
Designed to address the main problem identified by charge point owners/ operators when fast charging (low uptime), the Raption 50 series is bases on state-of-the-art modular power technology.

Another key attribute considered was its exterior design. Sophisticated, slim and robust are just some adjectives that can be used to describe this series and features that make it ideal for any type of site (from the most stylish urban area to industrial sites).
