Home charging
See the annual cost of home charging on the G11, G12 or G12w tariff, check whether your session fits the cheap night window, and work out how fast a specific wallbox pays for itself.
How many kilometres you typically drive in one day.
Real, priced home AC wallboxes from the EvCompass catalogue — power and price decide whether the session fits the night window and when the wallbox pays for itself.

PGE Dystrybucja — tariffs and price lists
PGE Dystrybucja's standard two-zone schedule — a different grid operator may set slightly different hours, and the source page's own content could not be automatically re-verified word-for-word. This calculator only models the overnight window, 22:00-06:00; the real tariff also has a shorter midday window (13:00-15:00 in winter, 15:00-17:00 in summer), shown on the strip but not treated as a second charging opportunity, since home charging happens overnight in practice.

Home charging FAQ
- Where does the cheap night window come from?
- It's PGE Dystrybucja's standard two-zone schedule: cheaper from 22:00 to 6:00 every night (and, under G12w, all weekend too). A different grid operator may set slightly different hours — check your own meter for the exact window.
- Which wallboxes does the calculator use?
- Only real, published home AC wallboxes from the EvCompass catalogue that carry both a price and a max power — not every wallbox in the catalogue meets both, so the list can be shorter than the full catalogue.
- What is home charging compared against?
- Savings and wallbox payback are measured against an indicative average price for public DC charging in Poland — an illustrative midpoint, not a measured figure, so treat the result as an order of magnitude, not an exact bill.
