hotel load

Definitions

The electrical load caused by all systems on a vehicle (especially a marine vessel or a truck) other than propulsion.

Examples

“Auxiliary power units provide⟳ electricity to all systems aboard a ship except main propulsion. These systems include⟳ hotel services (lighting, plumbing, and pumps for water), […] Cruise ships […] have⟳ big hotel loads; hence, quiet, unobtrusive fuel cell auxiliary power units may be particularly suited for this type⟳ of ship.”

“As well as providing the propulsive power, the batteries also have⟳ to provide⟳ power for the operation of sensors, weapons and auxiliary machinery and those for habitability, ventilation and air-conditioning of the crew. They constitute a steady drain on the batteries, governed by the length of time submerged, and together are termed the Hotel Load⟳.”

“The "hotel load⟳" (i.e., the electricity required for people), in watts per square foot, was multiplied by the module area[…].”

“[I]n heavy-duty, long haul trucking as much as 40 percent of engine run⟳ time is spent idling to provide⟳ auxiliary (nonmotive) power. Many of these energy demands are "hotel" loads, for example, heating or cooling a sleeping/living compartment, refrigerators, stoves, entertainment systems, and so forth.”

“Here the total electrical power consumed by the vehicle, P, is equal to the sum of the propulsion power, P#95;#123;prop#125; and hotel load⟳, H. Hotel load⟳ is simply the power consumed by all subsystems other than propulsion.”
