Introduction to EV
Electric vehicles (EVs) are vehicles that are partially or entirely powered by electricity. They have fewer emissions than petrol or diesel vehicles and produce no exhaust emissions. EVs are also environmentally favourable because they utilise little or no fossil fuels.
EVs have minimal operating expenses since they have fewer moving parts to maintain. They can also be charged with renewable energy to further reduce their carbon footprint.
As EVs and charging facilities are built, hazardous emissions in the transportation industry can be dramatically reduced.
Many considerations should be addressed while selecting charging equipment, including:
⦁ Networking
⦁ Capabilities for payment
⦁ Maintenance and operation
Charging times might range from less than 20 minutes to more than 20 hours. Level 1 or level 2 charging at 110-240 volts takes 2-8 hours to completely charge. Level 3 charging, at 480 V, takes about 20 to 40 minutes.
Demand for electric vehicle (EV) charging infrastructure
Several factors are driving up demand for electric vehicle (EV) charging infrastructure, including
⦁ Heightened environmental concerns
⦁ Innovations in technology
⦁ Consumer preferences are changing.
⦁ Initiatives by the government to encourage the development of EV charging stations
⦁ EV output is increasing.
⦁ Charging load variations
By 2028, the number of electric vehicles on the road is predicted to reach 310 million. rise meet these vehicles' charging needs, the EV charging industry will need rise nearly tenfold.
The presence of charging stations along popular travel routes can make it easier for EV drivers to refuel their vehicles. This provides them confidence that they will be able to complete their journey without having to worry about running out of battery power.
There were 2.7 million public charging points globally as of the end of 2022. With over 1.8 million publicly accessible electric vehicle chargers, China had the most extensive public charging infrastructure. The United States came in third place, with 100,000 slow chargers and approximately 28,000 fast charges.
There will be 26 million electric automobiles on the world's roads in 2023, a 60% increase from 2021. According to the International Energy Agency, over 14 million EVs will be sold globally by 2023, accounting for around 18% of total car sales. This would be a 35% increase year over year.
China continues to dominate the worldwide EV market. China now accounts for more than half of all electric vehicles on the road worldwide. The country has already surpassed its target for new energy vehicle sales by 2025.
There will be over 1,385,000 plug-in automobiles in the UK by the end of August 2023. This comprises around 850,000 battery-electric vehicles and 530,000 plug-in hybrid electric vehicles. More than 365,000 plug-in hybrid and battery-electric vehicles were registered last year, representing a 20% increase over 2021.
By 2028, the number of electric vehicles on the road is predicted to reach 310 million. rise meet these vehicles' charging needs, the EV charging industry will need rise nearly tenfold.
EV Charging Solution Types
There are multiple types of EV (Electric Vehicle) chargers available to meet a variety of charging requirements. Based on charging speed and power output, these chargers are classified into three major levels.
1. Charger Level 1 (AC Charging)
⦁ Voltage is 120 volts in North America and 230 volts in Europe.
⦁ Typical power output: 1.3 to 1.9 kW
⦁ NEMA 5-15 (North America) or Type 2 (Europe) common connector.
⦁ Charging Time: The slowest charging option, appropriate for charging at home overnight.
⦁ Usage: Simple chargers that plug into a typical household socket. Frequently seen in electric automobiles.
2. Charger Level 2 (AC Charging)
⦁ Voltage is 240 volts in North America and 230 volts in Europe.
⦁ Power output: 3.3 kW to 22 kW (residential to commercial) is typical.
⦁ J1772 (North America) or Type 2 (Mennekes) (Europe) Common Connector
⦁ Faster charging time than Level 1, suited for home and public charging.
⦁ Common applications include home charging stations, office charging, and public charging networks.
3. Charger Level 3 (DC Fast Charging)
⦁ Voltage: 200-600 volts or higher is typical.
⦁ Power Output: Typically ranges from 25 and 350 kW or more.
⦁ CCS (Combined Charging System), CHAdeMO, and Tesla Supercharger are examples of common connectors.
⦁ Fast charging can deliver an 80% charge in as little as 20-30 minutes.
⦁ Usage: Primarily utilised for long-distance travel and speedy charging along high streets.
Wireless Charging Solution
There are other wireless charging solutions, often known as "inductive charging," that eliminate the need for physical cords.
These technologies transfer power between a charging pad (on the ground) and a receiving pad (on the EV) via electromagnetic fields.
Wireless charging is still in its infancy and is only present in a few sectors and applications.
Charging Connector Specifications/Standards
Electric vehicle (EV) charging connector standards are becoming more stringent. The SAE J1772 connector is the industry standard for all Level 1 and Level 2 charging electric vehicles. It is popular in the United States and Japan. In Europe, the IEC 62196 type 2 connector is used. China employs a variant of the GB/T connection.
The CCS (Combined Charging System) connector enables both AC and DC charging to take place on the same port. It includes a J1772 outlet. The CCS format has been adopted by both European and American automakers.
Tesla's formerly unique charging connector has been dubbed "North American Charging Standard" (NACS). They opened the standard to allow other EV manufacturers to use the standards.
Benefits of EV Charging Solutions
Electric vehicles (EVs)
have a number of environmental advantages, including:
Reduced emissions: Because EVs do not
have tailpipe emissions, vehicles do not emit carbon dioxide or other harmful
emissions when driving. This aids in the reduction of air pollution, smog, and
global warming.
Lower carbon footprint: EVs emit less pollution
than gasoline-powered vehicles, even when the electricity they utilize is
derived from fossil fuels. If more renewable energy sources, such as wind and
solar, are used to generate electricity, the total greenhouse gas (GHG)
emissions connected with EVs might be considerably lower.
Silent operation: Because EVs do not
have an engine under the hood, they may operate quietly.
However, most electric
power plants emit pollutants, and there are additional emissions connected with
the extraction, processing, and distribution of the basic energy sources used
to generate electricity.
Because electric cars
(EVs) are more efficient than typical petrol or diesel vehicles, charging an EV
is less expensive than filling up. Charging an EV is less expensive than refueling
since electricity is less expensive than petrol or diesel.
Furthermore, because they do not incur
considerable wear and tear, EVs have cheaper maintenance expenses. According to
a 2020 Consumer Reports study, EV owners spend 60% less on fuel than owners of
internal combustion engine vehicles.
EVs, on the other hand,
typically have greater initial purchase pricing. The cost of charging an
electric vehicle is determined by various factors, including:
- Where you will charge
- The cost of electricity
- The time of day at which you charge
- Your vehicle's efficiency
In India, for example,
charging an EV at a charging station costs between Rs100-200, While Charging at
home cost between Rs 180-500.
Charging an EV at home can be more convenient and
efficient than using a public charging station. You can leave
your car plugged in overnight or whenever you're not using
it and wake up to a completely
charged battery.
Consider the following factors when selecting a home EV
charger:
How many amps are available for charging in your
home?
If your panel is nearly or completely filled, you may need to
improve your electrical service.
Purchasing a charger based on your EV's maximum charging
rate
Having the charger installed by a professional
You can track your charge history and set particular
charging schedules for each day.
