EV and e-bike charging at a tiny home
Updated 4 Nov 2026. Charging a vehicle can be the biggest single load at a tiny home. Here's what it takes.
1. Energy needed (estimates)
| Vehicle | Typical battery | Est. energy from the wall per full charge |
|---|---|---|
| E-scooter | ~0.3 to 0.75 kWh | ~0.35 to 0.9 kWh |
| E-bike | ~0.4 to 1 kWh | ~0.5 to 1.2 kWh |
| E-moped | ~2 to 4 kWh | ~2.3 to 4.6 kWh |
| Electric car, 40 km commute | — | ~6 to 9 kWh per day |
All figures on this page are estimates for planning. Real use depends on climate, appliances and habits.
2. What works off-grid
- E-bikes and scooters: easy on a small solar and battery system. See charging from a power station.
- Electric cars: a daily commute can double or triple a tiny home's solar needs, so plan for about 2 to 3 kW of extra panels and charge in daylight, or use shore power or public charging. See solar sizing.
- A portable cable (Mode 2, about 1.8 to 2.4 kW) is often enough at a tiny home. A 7 kW wall charger needs a strong supply.
3. Choosing a charger
See our full guide to home chargers for e-bikes, e-scooters, e-motorbikes and EVs, including connector types, kW ratings and UK smart charge point rules.
Where to buy
E-bikes: E-bikes at ENGWE (US) (affiliate link). Portable power: Power stations at ALLPOWERS (US & CA) (affiliate link).
EV wall chargers: we're still waiting on approval from charger brands. Until then, use a reputable local installer.
Tiny home rules by country (summary)
General information only, checked against official sources on 4 Nov 2026. Rules change and vary by state, province and council, so always confirm locally.
| Country / region | Key rule | Official source |
|---|---|---|
| New Zealand | A tiny house that is immovable and lived in long term is generally a building needing consent. Since 15 Jan 2026, a new single-storey standalone dwelling up to 70 m² can be built without building consent if it meets the exemption conditions, uses licensed professionals, and you get a PIM first and notify council at the end. | MBIE tiny houses · MBIE granny flat exemption |
| Australia (NSW) | A tiny house on wheels is usually a moveable dwelling/caravan. Approval exemptions are limited (for example short stays of up to 2 days in a row and 60 days a year). Otherwise expect a development application and Local Government Act s68 approval. | NSW Moveable Dwellings Regulation 2021 |
| Australia (Victoria) | A fixed "small second dwelling" up to 60 m² on a lot with an existing home often needs no planning permit, but a building permit is always required. | Victorian Building Authority |
| United States | Permanently occupied tiny houses fall under the International Residential Code (Appendix AQ, 400 sq ft or less, where adopted locally). Wheeled units built as Park Model RVs (ANSI A119.5, up to 400 sq ft) are for recreational or seasonal use, and local zoning decides where they can stay. | ICC tiny house white paper · RVIA |
| Canada | Year-round tiny homes must meet the local building code and zoning. RV-certified units (CSA Z240 RV) are not for permanent residence. | City of Calgary example |
| United Kingdom | A unit can legally be a "caravan" if movable and within 20 m × 6.8 m (3.05 m internal height). Living in one as a separate home usually needs planning permission. Ancillary use by the same household in a house's garden may not. | Caravan Sites Act 1968 s13 · GOV.UK caravan definition |
| France | A tiny house without foundations, quickly removable and used as a main home at least 8 months a year can count as a "résidence démontable", which still needs a planning declaration or permit. | Ordre des architectes (cites Code de l'urbanisme R111-51) |
| Germany | A permanently lived-in tiny house, even on wheels, is generally treated as a building that needs a permit under the state building code. | City of Munich guide (PDF) |
| Japan | A trailer house counts as a vehicle rather than a building only if it can be moved at any time and is legal on public roads, with no fixed stairs and only quick-disconnect utilities. Otherwise it needs building approval. | Hamamatsu City (Japanese) |
Electrical work: in most countries, mains wiring and grid-connected solar or batteries must be installed and certified by a licensed electrician. NZ example: WorkSafe DIY solar.
