Free interactive tool

Design your EV charging hub
in 3D.

Lay out chargers, bays and grid equipment on your own site plan. Cables size themselves, Willbert list prices fill in as you go, and your client gets a 3D proposal behind one link.

Runs in your browser. Start without an account; register free for prices and proposals.

How it works

From site plan to proposal in three steps.

  1. Lay out the site

    Drop in a PDF site plan or a satellite screenshot, set its scale, and place chargers, bays, transformers and storage on it — or start from the demo site.

  2. Size and price it

    Connect the equipment and every cable run sizes itself. With a free account, Willbert list prices fill in as you go and you add your own margin.

  3. Send the proposal

    Save one or more options under a proposal. Your client opens a single link and compares them in 3D, prices included.

Features

Everything you need to size, cost and pitch a charging site.

Site plans

Start from the real site

Upload a PDF site plan or an image — a satellite screenshot works — and give it its print scale, such as 1:500, or its real width. It lies under your layout at true size, so everything you place is to scale.

  • First page of a PDF, rendered sharp
  • Scale by print ratio or width in metres
  • Move, rotate and fade it under the layout

3D layout

Real equipment, to scale

Amber II chargers modelled from Willbert's own CAD files, S-Hub canopies that snap onto them, transformers, switchboards, battery storage, bays, surfaces and street furniture — in a 3D scene you can present in daylight.

  • Snaps to a 1 m grid and 15° steps
  • Live distances between selected objects
  • Multi-select, copy and paste, 100 undo steps

Cabling

Cables that size themselves

AC feeds, S-Hub buses, DC links and battery feeds each get the cheapest cable that carries the load with a margin, keeps voltage drop within 3% and fits the equipment's terminals. Move anything and every run re-sizes.

  • Run lengths follow the route, trench depth included
  • Earth and neutral added on AC runs
  • Override any cable — failed checks are flagged

Live pricing

Prices as you design

With a free account every layout prices itself from Willbert's Amber II list: units, power modules, cable sets and every cable run. Set a discount or add your margin once, and the customer price follows.

  • Bill of materials by brand, with a conductor order list
  • Quote price per unit, shown against the list price
  • Copy the BOM as text for your own quote

Client proposals

A proposal your client can open

Save each option as a scenario of one proposal and send a single link. Your client sees them in a 3D daylight viewer — power at every bay, the wiring, and a side-by-side summary with totals — on a laptop or tablet, without signing in.

  • Charging power at each bay, and what limits it
  • All options side by side, with installed power and totals
  • 5 proposals a month free, unlimited with Studio

Studio

Compare Amber II with the alternatives

Studio opens the Alpitronic and Kempower libraries. Lay out a competing or mixed-vendor configuration on the same site, save it next to your Amber II option, and let the proposal summary compare them.

  • Alpitronic HYC400 and HYC1000, with MCS dispensers
  • Kempower power units, satellites and station chargers
  • Third-party prices are indicative — adjust them per design

No. The editor, site-plan underlays, cable sizing and material quantities all work without one. Register free — name, work email and company — to see prices and save proposals for your clients.
Willbert Amber II prices are our current list prices. Alpitronic and Kempower prices are indicative, and you can override any price for a single design. Transformers, switchgear, storage and canopies aren't priced yet, so totals cover the chargers — with foundations, installation and options — and the cabling.
A link to a read-only 3D presentation of every option in the proposal: the site in daylight, the charging power at each bay, the wiring, and a summary table with totals. It opens in any modern browser, on a tablet too, without signing in.
While you design, nothing is uploaded — and nothing is saved, so a reload loses unsaved work. When you save a proposal, the layout and any site plan you attached are stored on Willbert's servers, and anyone with the link can open it.
Studio costs €89 per user per month, paid by card through Viva.com. The first month is charged when you upgrade, then every 30 days. Stop renewals in the app at any time and Studio stays on until the paid period ends.
Not today. You can copy the bill of materials as text into your own quote, and share the layout itself as a proposal link.
Design on a laptop or desktop — the editor needs a mouse. The proposal viewer your clients open works on tablets and phones as well.
