A power wheelchair is an electric vehicle that propels the user forward by means of the power of batteries. These vehicles are characterized by a front- or back-wheel drive system. These wheelchairs are usually equipped with a manual tilt and recline system to enable the user to change positions as needed. The first electric wheelchairs that were commercially produced were heavy manual folding-frame wheelchairs powered by lead-acid batteries. These wheelchairs were primitive and had no programmability. The seating systems were typically sling-seats and back upholstery. Those designs offered limited postural support and were not designed for use by wheelchair users with limited mobility.
The design of an electric wheelchair has changed dramatically over the past decade, from simple push-button controls to complex microprocessing. A direct drive system delivers power to a single pair of wheels, with additional sets of wheels providing stability. These types of systems also typically feature active and dynamic braking, which stop the motor when the wheelchair is moving, and offer greater control than coasting. Depending on the manufacturer, some models even feature an optional joystick controller that can be used to operate the wheelchair with one hand.
The range of an electric wheelchair depends on the model and its weight. The maximum range is around 20 miles, and some models can reach six mph. The design of electric wheelchairs differs from one another. Those with mobility problems may require a smaller power wheelchair. Unlike a mobility scooter, an electric wheelchair is more compact and maneuverable. It is also a great option for indoor use.Using an electric wheelchair should be supervised by a medical professional, who can instruct the patient on how to use the device.
As per latest report published by Coherent Market Insights, the global electric wheelchair marketwas valued at US$ 6,387.3 Mn in 2021, and is expected to exhibit a CAGR of 10.7% over the forecast period 2021-2028.
The first thing to look for is a good battery life. An electric wheelchair can be overcharged and the result could be a damaged battery. The battery life can also be impacted by rust. To prevent this problem, it is important to regularly check the batteries. A visual inspection should detect green acid at the terminals of the battery, which is a sign of a malfunction. Moreover, an abnormally low voltage can cause the power wheelchair to stop working completely.Along with checking the batteries, the electric wheelchair should also be checked for worn or rusted seats. A weak battery can affect the structural integrity of the chair. In order to check the batteries, the user should look for abnormally low battery voltage and signs of rust.
There are many advantages to an electric wheelchair. They are useful for people with disabilities who are unable to push a manual chair or do not have the dexterity to drive it. These powerchairs offer many functions that manual wheelchairs cannot. They can tilt and recline manually, lift legs and seats, and have adjustable arm and leg rests. These features help the disabled person feel more comfortable and can be used anywhere they want. A powerchair with a battery charger and additional batteries can be used anywhere.
