The Future is Electric: Your Guide to EVs

As electric vehicles (EVs) become more advanced and accessible, they’re reshaping the future of transportation with cleaner, quieter, and more efficient options. From innovative battery technology to expanding charging networks, EVs offer substantial benefits for both drivers and the environment. With reduced emissions, lower running costs, and impressive performance features, EVs represent an exciting shift towards sustainable mobility, driving us closer to a greener, electrified world that’s within reach for everyone.

The Evolution of EVs

“My goal is the acceleration of the advent of electric cars.”

This statement was made by futurist and entrepreneur Elon Musk back in 2015. Since then, the tech giant, Tesla, has become a champion in the electric vehicle industry. But they’re not the only company making waves.

A new era of automobiles has dawned with the entry of electric vehicles into the automobile sector. As the world runs out of non-renewable sources like fossil fuels, it’s essential to shift to more environmentally friendly transportation.

Electric vehicles are the most sustainable and eco-friendly substitute for vehicles that run on petrol or diesel. This massive industrial conversion marks a “shift from a fuel-intensive to a material-intensive energy system,” according to the International Energy Agency (IEA).

Most people ask, “Why should we shift from fuel-intensive vehicles to EVs?”

Well, there are innumerable benefits, some of which are:

1. EV’s are environmentally friendly.
2. EVs can help improve fuel economy.
3. They’re ultimately cost-effective.

But there’s more to know. Let’s dive deeper!

Types of Electric Vehicles

Vehicles are partially or fully electric, and based on that, there are four types of EVs:

• Battery EV: These EVs don’t have an Internal Combustion Engine (ICE) that conventional vehicles use. BEVs consist of a battery that is charged by plugging in at the electricity grid. The battery, in turn, provides energy to the electric motor to run the EV.
• Hybrid EV: HEVs have an Internal Combustion Engine (ICE) as well as an electric motor. The battery can only be charged by the combustion of fuel in the ICE, the motion of the wheels, or both. There is no provision for charging the battery through a port.
• Plug-in Hybrid EV: PHEVs also have both an ICE and an electric motor. However, in PHEVs, the battery can be charged by fuel combustion in ICE and plugging into an electric outlet.
• Fuel Cell EV: These are called zero-emission vehicles and are one of the most promising forms of transportation. These EVs work on fuel cell technology where hydrogen is used as a fuel. The chemical energy liberated is converted to electrical energy, which in turn runs the electric motor.

Types of Batteries

There are four types of batteries used in EVs:

Lithium-Ion Batteries

This is the most common type of battery used in EVs. Lithium-Ion batteries have a low “self-discharge” level, which makes them better at holding a full charge. The discharge efficiency is 95-99%, and the self-discharge is 1-5% per month.

Nickel Metal Hydride Batteries

These batteries are primarily used in hybrid electric vehicles, but they are more expensive than lithium-ion batteries. The discharge efficiency is 65-80%, and the self-discharge is around 30% per month.

Lead-acid Batteries

Compared to lithium-ion and nickel metal hydride batteries, lead-acid batteries are heavier and cheaper. Their discharge efficiency is 70-92%, and the self-discharge is 3-20% per month.

Ultra-capacitors

These are used as secondary batteries in vehicles to handle more load. They provide extra power during acceleration and power-braking.

Driving Range

Most of the customers have “range anxiety” when they consider buying an EV. They fear being stranded on the road with an empty battery pack and no charging station in sight.

According to the Washington Post, people’s anxiety over this is largely overblown. The average range of an EV is 120-250 miles, which easily covers most people’s daily distance.

As battery technology continues to advance, the distances an EV can cover on one charge grows, so there’s no need to be worried about this.

Fully vs. Hybrid Electric Vehicles

A hybrid EV can run both on fuel and electrical energy. Depending on your lifestyle and usage of your vehicle, you can opt for either of them. If a fully electric vehicle is not practical for you, either opt for an HEV (it still produces fewer emissions than traditional cars) or wait until battery tech improves, which is happening at a rapid rate.

Battery Life and Maintenance

Battery life is one of the most crucial factors while buying an EV. Invest in an EV with a long battery life as replacing a battery can increase the maintenance cost significantly, and in some cases, prohibitively.

However, most EVs on the market have reasonable battery lives. “The average EV battery pack’s lifespan to be at around 200,000 miles, which is nearly 17 years of use if driven 12,000 miles per year,” according to Consumer Reports.

The maintenance cost of EVs is low, as the number of moving parts – and therefore the number of parts that wear out – in these cars are few. On average, EV drivers pay half as much to repair and maintain their vehicles compared to their gasoline counterparts.

Power, Torque, and Acceleration

Power, torque and acceleration are three factors that determine the performance of an EV.

Power is the mechanical output provided by the electrical energy produced by the battery. Power is represented in horsepower, and it affects the acceleration of the vehicle. The higher the value of power, the better the acceleration.

Torque is the rotating force produced by the motor. This helps the vehicle accelerate initially and is why heavier automobiles use engines that deliver higher torque. A higher torque value means better load-bearing ability.

Acceleration is the rate of change of velocity, and it depends on the value of torque. The acceleration of EVs is at par with fuel-powered vehicles because the torque produced by electric motors is comparatively higher. In a fuel-powered car, a lot of power is absorbed by the moving parts. On the contrary, EVs are more efficient as they have fewer moving parts. The value of acceleration also depends on the number of electric motors installed in an EV.

Charging an EV

There are different ways to charge a EV and the required time depends on the power source and charger capacity. Your car battery can be fully charged in as little as half an hour or it could take as long as half a day.

Electric automobile technology is booming, and it has developed fast charging technology for EVs. The different ways to charge an EV are:

There have been new advancements in the charging technology of EVs recently. Engineers at Penn State University have developed a battery that has a range of 320-480 km with just 10 minutes of charge.

The Director of Electrochemical Engine Center at Penn State, Chao-Yang Wang believes that “the 10-minute trend is the future and is essential for the adoption of electric vehicles because it solves the range anxiety problem”.

Benefits and Challenges of an EV

As a consumer, EVs have more benefits than challenges. These include:

Users all across the world are taking an interest in EVs as the technology is advancing rapidly. It’s safe to say that electric vehicles are the future of sustainable transportation.

However, the public’s willingness to shift from fuel-intensive vehicles to EVs is a crucial factor. Let’s make informed choices while buying a new vehicle and move towards a sustainable future together.
