Energy stored
Battery capacity is measured in kWh. Usable capacity matters more than a nominal headline.
Electric narrowboat buyer guide
Electric Narrowboat Range, Batteries and Charging.
Range is the result of boat speed, hull and propeller efficiency, battery energy, weather, waterways, domestic demand and available charging.
A better way to discuss range
Start with the cruising day, not a single mileage claim.
Canal speed, lock time, current, wind, shallow water, propeller condition and throttle use can all change consumption.
Energy used
Motor demand rises with speed and difficult water conditions, while domestic appliances use the same stored energy.
Energy returned
Solar, shoreline and generator support determine how quickly the system can be replenished.
Battery specification
Capacity should follow the intended use.
A boat used for shorter summer cruising has a different requirement from a liveaboard making consecutive winter journeys. Cooking, refrigeration, laundry, working aboard and heating controls all belong in the energy budget.
Oakums plans propulsion and domestic loads together, then considers charging opportunities and sensible reserve.
Charging strategy
Solar, shoreline and generator each have a role.
A resilient system is designed for changing seasons and real waterways rather than one ideal summer day.
Solar
Quiet daily contribution affected by roof area, season, weather and shading.
Solar power guide →Shoreline
Dependable charging when a suitable supply and berth are available.
Generator
Optional support for sustained demand, winter use or extended cruising where required.
