Charging in The Future: Why is Fast Charging Important for Electric Vehicles

Auth Anushka Agarwal | Apr 28,2020

Charging electric vehicles isn’t the same as refueling combustion in a vehicle. Several EV campaigns postulated, it takes 8-10 hours to charge an electric vehicle. Embracing electric vehicles is not going to help us until we power it with technologies that ensure the comfort and safety of the driver. There has been quite development in the market owing to electric vehicles, but there are far more concerns that we have to fight before adopting EVs.

Transitioning to electric vehicles transportation will require a behavioral shift for drivers, from refilling their fuel tanks every week or two, and going for a top-up charge daily. Since charging doesn’t provide longevity as the fuel-powered units, choosing EVs will be a paradigm shift for the users. As for the charging stations, convenience and stability are two things that’ll matter a lot. EV charging should happen anywhere and anytime, so refueling stations have to be converted into power sockets.

EV charging is, however, very easy because there are only two types of fuels available, AC and DC. As the adoption of electric vehicles is on a surge, especially in the urban settlements, so does the need for charging stations worldwide. The most notable installations have to be near expressways, highways, and transportation corridors. The coming decade is going to see several innovations in the field of AA and AAA rechargeable batteries. Charging infrastructure needs to be developed to power vehicles along with the major circuits worldwide. Since EV is becoming a reality, fast charging and hassle-free charging stations are the two most important considerations that need to be discussed.

In the coming times, charging that can provide at least half-a-tank in about 10 minutes.


An electric vehicle for a 200-mile operation requires a battery size of approximately 60kWh. For charging half a tank i.e., 30kWh in 10 minutes requires a power of 180kW. This means that a power station needs to deliver around 200kWh in 10minutes. To explain it in layman terms, this is the amount of power used by an entire residential unit. Since these chargers will be expensive and big, they need to be shared with thousands of vehicles every day. The charging stations have to be equipped with such tech, which enables it to charge thousands of vehicles at a very fast rate.

One of the biggest problems researches will face is the deterioration suffered by the battery if charged fast for every running cycle. Data for the same suggests that without any fast charging, the battery will remain 90% of its original state eve after 700 running cycles. However, when engaged in fast charging phenomenon, the battery life is decreased substantially. This is the rapid degradation of the car batteries in a very short time even degrading the resale value of the cars. Customers today, are really smart. They’ll undergo extensive research before stepping into the arcade of electric vehicles. Such problems are going to undermine its adoption in the coming time. Therefore, proper research in the same fields needs to be conducted if the automobile industry has to be electrified in the coming decades.

What is AC Charging all About?

When talking about developing charging units, the idea is to think in terms of kilometers per hour- that is, how many kilometers can be added to a vehicle battery in an hour. AC chargers are specifically known to charge at slower rates. Since most of the vehicles come with their own cord set, it can be plugged into any conventional socket anywhere. The impact on the electricity grid is going to be tremendous, and it needs to be thought of. In case, you need a fast charge supply, it can be purchased from several different providers to supply an increased charging rate at home or for other applications like a commercial or residential block. This also increases the needs of the dedicated workplace or general chargers that have a limited impact on the electricity grid. Modern EV chargers have to be developed so that people can take advantage of the lower electricity charging rates.

What is Top-up Charging?

Most of the electric car drivers’ plug-in vehicles whenever they park, generally overnight, or during the day at available stations. This is called as top-up charging. Instead of letting your battery run empty, drivers use the time when the vehicle is idle or is parked somewhere. Overseas locations where electric vehicles running on the road is prominently increasing, people generally run their car to and fro to the office. Also, public and workplace charging points range from 7kW to 22kW. This is an effective way to keep your electric car ready to go at all times.

Factors that Affect the Charging Speed of EVs

Five major factors decide the charging potential of electric vehicles.

Size of the Battery:

The bigger your vehicle’s battery capacity, the more time it needs to completely charge it.

State of the Battery:

If you are charging your vehicle when the battery is completely empty, it’ll take longer to charge compared to a partial empty battery state.

The Maximum Charging Rate of the Vehicle:

You can charge a vehicle’s battery at the maximum charge rate stated by the manufacturers. Exceeding it, can hamper the long life of your battery.

The Maximum Charging Rate of the Charge Point:

The time a battery takes for completely charging will also depend on the charging rate of the charge point station.

Various Environmental Factors:

A cold temperature extends the charging time of a vehicle.


A comprehensive approach needs to be devised to electrify the global automobile and transport circuit. Opting for environment-friendly batteries, like SmartCell batteries is a start towards an electrically powered future.
