DC Direct Current Battery Power

The 21st Century DC Battery Powered Stairlift

 

Today, in the 21st century, the direct current (DC) storage battery is a dominant  factor,  which is now used extensively in a host of personal, residential and commercial applications such as the modern DC Battery Power, battery powered stairlift, cell phone, iPod, computer and tablet, smoke detector, electric razor, power drill, mp3 player, thermostat, laptop or smartphone. These products plug in to an AC outlet, and yet its technology relies mainly on direct current (DC) battery power.

 

Direct current (DC) is the unidirectional flow of electric charge produced by sources such as batteries or solar cells while Alternating Current (AC) is the form in which electric power is delivered to businesses and residences.

 
Thomas Edison, world’s greatest inventor, was entirely self-taught. Everything he knew about science he had learned from books and by tinkering with chemicals and telegraph equipment. Edison engages in a "war of the currents" with George Westinghouse as he challenges the safety of the new alternating-current (AC) electric systems with evidence conducted at his laboratory.
 
In 1909 Edison markets his direct current (DC) alkaline storage battery, which is now used extensively in a host of personal, residential and commercial applications.

AC and DC Power

Simple AC Generator
Simple AC Generator
Earlier AC Electric designed stairlifts run off the Mains electricity power supply and require a higher voltage trailing cable to power and drive the stairlift motor. Many designs have been employed by stairlift manufacturers in the way this is accomplished.
 
The original stairlifts typically had AC (alternating current) drive motors which operated at full mains house voltage about 110 volts in the USA and 230 volts in Europe. A “power cable “passes beside or through the track rail to carry the electrical power from the supply point to the carriage. 
 
 

AC/DC what is the Difference?

 
In 1887 direct current (DC) power was king. At that time there were 121 Edison power stations scattered across the United States delivering DC electricity to its customers. But DC power had a great limitation -- namely, that power plants could only send DC electricity about a mile before the electricity began to lose power. So when George Westinghouse introduced his system based on high-voltage alternating current (AC), which could carry electricity hundreds of miles with little loss of power, people naturally took notice. A "battle of the currents" ensued. In the end, Westinghouse's AC alternating current prevailed. Alternating Current (AC) is the form in which electric power is delivered to businesses and residences. The AC power system used today developed rapidly after 1886, during the latter part of the 19th and early 20th century.
Rechargeable Sealed DC Stairlift Battery

The original stairlifts typically had AC (alternating current) drive motors which operated at full mains house voltage about 110 volts in the USA and 230 volts in Europe. A “power cable “passes beside or through the track rail to carry the electrical power from the supply point to the carriage.
 
Earlier AC Electric designed stairlifts run off the Mains power supply and requires a higher voltage trailing cable to power and drive the stairlift motor. Many designs have been employed by stairlift manufacturers in the way this is accomplished.
 
Increasingly today, modern home stairlifts are power-driven from rechargeable sealed batteries housed inside the carriage to refresh the capacity of electric power required and use DC battery (direct current). A Battery Power DC stairlift will safely continue operating in an electrical home power outage, provided the batteries are fully charged and will generally power 15-20 trips (30-40 roundtrips) up and down the stairs.

Power Generator

  • Stair lifts are either AC powered directly using the electricity from your home or are DC rechargeable battery pack powered.
  • If there is an electrical power failure, the Battery Operating System (BOS) will operate for as long as the batteries last (typically 20 return trips).
  • It is a good idea to buy a backup power generator in the case of an extended long term electrical power failure, possibly after a severe storm or hurricane. When it might take days for the power to come back on.
  • Since stair lifts are essential in aiding a person up and down the stairs, a backup power generator will ensure that a person will not be confined to one level of the home; if the electricity is not reinstated for an extended period of time.
