Before you buy a smart TV, think about these seven things. The majority of televisions sold today are smart TVs, also known as connected TVs. Smart TVs are the convergence of computers and entertainment, with built-in internet and a plethora of free and paid apps. This buying guide will assist you in deciding which smart TV to purchase based on your needs, budget, and preferences. What Exactly Is a Smart TV? A smart TV includes an operating system, which allows users to access streaming content without the need for an external device. People who enjoy watching the latest shows on Netflix, Hulu, and other streaming platforms are fans of smart TVs. A smart TV allows you to access, manage, and view online and network-based content. Almost all TVs sold today are considered smart TVs, and many manufacturers sell them, including LG, Vizio, and Samsung. Top 7 Things to Think About When Purchasing a Smart TV When shopping for a smart TV, there are seven key factors to consider: Cost Size Reso...

Every vehicle on the road requires two basic components: something to propel it forward and something to stop it. The internal combustion engine (ICE) used in gasoline-powered cars has met the first need for over a century, while wasteful friction brakes have met the latter. One feature that distinguishes electric vehicles (EVs) is their ability to hit both targets with a single shot: the same electric motor that powers an EV can also serve as a generator, slowing the vehicle while also storing extra electricity in a process known as regenerative braking. What Exactly Is Regenerative Braking? Regenerative braking is a term that means exactly what it says. When regenerative brakes are engaged, the vehicle slows while also regenerating some of the electricity that was used to accelerate it. That electricity is recycled into the batteries, where it can be used to power the vehicle again in the future. This is in contrast to traditional brakes, which produce only heat and noise when slowin...

Although gasoline-powered vehicles continue to dominate the auto market, EV technology has matured to the point where you may be wondering if your next car will be electric. If you're interested in electric vehicles but don't know where to begin, we can teach you what they are, what they can do, and where they're going. What Is an EV, Exactly? Electric vehicles (EVs) are becoming more popular, with sales increasing year after year and a wide range of models available from nearly every major manufacturer. An EV is simply a vehicle that runs on batteries rather than fossil fuels. An EV, like a gasoline-powered vehicle, has a gas tank that supplies fuel to the engine and a set of batteries that power an electric motor. There are many different types of EVs, including battery electric vehicles (BEVs), which only use battery power, and hybrids, which use both gasoline and battery power. Some electric vehicles even use hydrogen-powered fuel cells, but only pure battery-powered e...

One of the most common misconceptions about electric vehicles (EVs) is that they do not perform as well as gasoline-powered vehicles. Performance is a complicated subject, but EVs outperform their fossil-fueled counterparts in some key areas. High-performance EVs have blisteringly fast acceleration, impressive top speeds, and excellent handling. Gasoline-powered vehicles face stiff competition and benefit from over 100 years of research and development, but this race may be closer than you think. How Do Electric Vehicles Compare to Gasoline-Powered Vehicles? Electric and gas-powered vehicles are available in a range of performance levels, from low-performance budget models to high-performance luxury models and everything in between. Because there are many more gas vehicles on the road, there are more low- and high-performance gas models than electric vehicles, but electric vehicles have an advantage at both ends of the spectrum. One advantage that EVs have over gasoline-powered vehicl...

Consider electric vehicles a 21st-century fad. Nope! EVs have a history that dates back nearly two centuries. For years before gas-powered cars appeared on the scene, the first electric vehicles shared the road with horse-drawn and steam-powered carriages, and they grew in popularity as advances in battery technology and the growing availability of electricity made them ever more convenient to operate. The widespread availability of cheap gas in the early twentieth century aided in pushing EVs out of the public consciousness, but various automakers continued to work on related technology over the years. The modern electric vehicle was poised to reemerge near the turn of the century, thanks to further advances in battery technology and a push to reduce vehicle emissions. The First Electric Vehicles Below the images is a roadmap view of the electric car's history, complete with years and a timeline. Dos Diaz, Alex Over the last two centuries, electric vehicles have traveled a long a...

Why Do Electric Vehicles Outperform Gasoline Vehicles? In some ways, electric vehicles have gotten a bad rap over the years. However, being electric does not imply poor performance. In fact, it can imply the inverse. Torque, Horsepower, and Other Engine Paraphrases If you say "low emissions" and "high performance" in the same sentence, you'll probably get strange looks. Have you ever seen a muscle car with good fuel economy in over a century of automobiles? Even if it is difficult to believe, electric vehicles provide exceptional performance and low emissions. The key to incorporating both is how electric motors and internal combustion engines (ICE) generate torque and power. Torque is measured in pound-feet (lb-ft), and power is how much work the engine can do in horsepower (hp) or kilowatts (kW) (kW). Electric vehicle motors provide torque and power without the need for acceleration. Conventional ICEs (used in gasoline-powered vehicles) generate torque and po...

From the outside, electric vehicles may appear to be small toys in comparison to larger gas-powered vehicles. Although some may appear small on the outside and may fit better in smaller parking spaces, don't be fooled by their size: EVs actually pack the most space into the least amount of space.That's because EVs have more space than gas-powered counterparts because they have fewer moving parts. Furthermore, advances in design and technology make many parts of the vehicle smaller overall, giving EVs more space for passengers and cargo. The Complete Idiot's Guide to Electric Vehicles More Space = No Engine Engines, gas tanks, multi-speed gearboxes, exhaust systems, catalytic converters, and other large parts have always been included in gas-powered vehicles. EVs, on the other hand, do not require all of those large parts. They don't need an exhaust system or a catalytic converter because they don't burn fuel. A grille is unnecessary in an EV because there is no radi...

What's the Difference Between an EV (BEV), a PHEV, an FCEV, and a Hybrid? The electric vehicle landscape can be difficult to navigate, but the various types of EVs can be divided into the following basic categories: EV/ BEV: Because battery electric vehicles are entirely electric, they are sometimes abbreviated as EV as well as the more specific BEV. An electric motor is powered by a rechargeable battery in this type of vehicle. They can be charged slowly by a household outlet or quickly by a charging station. HEV: Hybrid electric vehicles have both an electric motor and a gas-powered internal combustion engine. There are various versions, but the majority of them begin with an electric motor and then switch to a gas engine. Standard HEVs cannot be charged by plugging them in. Instead, the batteries are charged while driving by the gas engine and regenerative braking. PHEV: Plug-in hybrid vehicles are hybrid electric vehicles that can be charged by plugging them in. This type has...

Just as gasoline and diesel engines were once considered new technology and derided by the horse-driven public, modern battery electric vehicles (EV) face the same criticism. Will electric vehicles last as long as gasoline and diesel vehicles? Yes, and automakers are already doing so. Myth: Neither EVs nor gasoline cars are invincible. Car and truck lifespan has increased since the first automobile went from production to daily driver to a cube in the junkyard. Despite a few outliers, such as Irv Gordon's 3.2-million-mile 1966 Volvo P1800S and Matt Farah's million-mile 1996 Lexus LS400, the average car's increasing life is encouraging. The average American car was only 5.5 years old in 1977. By 1995, the average was 8.4 years, and by 2020, it had risen to 11.9 years. That reveals a lot about today's typical driver expectations and the technological advances used to meet them: People want long-lasting automobiles. They expect any car they buy today, whether electric or ...
