Electric vehicles (EVs) are becoming more popular and affordable, as they offer many benefits such as lower emissions, lower maintenance costs, and higher efficiency. However, one of the main challenges that EV owners face is the availability and accessibility of charging stations. Unlike petrol stations, which are ubiquitous and convenient, EV charging stations are still scarce and often require long waiting times. Therefore, many potential EV buyers are deterred by the so-called “range anxiety”, the fear of running out of battery power before reaching their destination or a charging station.

So, when will EV charging stations replace petrol stations? The answer depends on several factors, such as the demand for EVs, the supply of charging infrastructure, the cost and speed of charging, and the policies and regulations that support or hinder the transition. In this article, we will explore some of these factors and their implications for the future of EVs and petrol stations.

Demand for EVs

The demand for EVs is influenced by various factors, such as consumer preferences, environmental awareness, technological innovation, and economic incentives. According to a report by BloombergNEF, global EV sales are expected to grow from 3.1 million in 2020 to 14 million in 2025, and to 54 million in 2040. By then, EVs will account for 58% of new passenger car sales and 31% of the global car fleet. The report also predicts that China, Europe, and the US will be the largest markets for EVs, with China leading the way with 48% of global EV sales by 2025.

One of the main drivers of EV demand is the increasing environmental awareness and concern among consumers and governments. As climate change becomes more evident and urgent, many people are looking for ways to reduce their carbon footprint and contribute to a greener future. EVs are seen as a viable solution, as they emit zero tailpipe emissions and can run on renewable energy sources. Moreover, many governments are implementing policies and regulations to encourage or mandate the adoption of EVs, such as subsidies, tax credits, emission standards, bans on internal combustion engine (ICE) vehicles, etc. For example, the UK has announced that it will ban the sale of new petrol and diesel cars by 2030, while Norway aims to achieve 100% zero-emission car sales by 2025.

Another factor that boosts EV demand is the rapid technological innovation and improvement in battery performance and cost. According to a report by McKinsey & Company, battery costs have declined by 87% from 2010 to 2019, reaching $156 per kilowatt-hour (kWh) in 2019. The report also projects that battery costs will drop below $100 per kWh by 2024, which is considered to be the tipping point for EVs to achieve cost parity with ICE vehicles. Furthermore, battery technology is also advancing in terms of energy density, durability, safety, and charging speed. For instance, Tesla has recently unveiled its new battery cell design that promises to increase energy density by 16%, reduce cost by 14%, and extend lifespan by 54%.

Supply of charging infrastructure

The supply of charging infrastructure is another crucial factor that affects the adoption and diffusion of EVs. Charging infrastructure refers to the network of public and private charging stations that provide electricity to EVs. Charging stations can be classified into three types based on their power output and charging speed: Level 1 (up to 2 kW), Level 2 (up to 19 kW), and Level 3 or fast charging (above 20 kW). Level 1 charging can take up to 20 hours to fully charge an EV battery, while Level 2 charging can take up to 8 hours. Level 3 or fast charging can reduce the charging time to less than an hour, but it is also more expensive and requires higher voltage and current.

According to a report by International Energy Agency (IEA), there were about 7.3 million chargers worldwide at the end of 2019, of which 6.5 million were private chargers at homes or workplaces, and only 0.8 million were public chargers. The report also estimates that there will be about 140 million chargers by 2030, assuming that there will be one public charger for every seven EVs. However, this ratio may vary depending on the availability of private chargers, the driving patterns and behaviors of EV owners, and the geographic distribution of EV demand.

One of the main challenges that hinder the expansion of charging infrastructure is the high cost and complexity of installation and operation. Charging stations require not only hardware components such as chargers, cables, connectors, and meters, but also software systems for communication, billing, and management. Moreover, charging stations need to be connected to the grid, which may require upgrades or reinforcements to cope with the increased electricity demand and load fluctuations. Furthermore, charging station operators need to consider the optimal location, size, and pricing of their stations to attract and retain customers, while also competing with other operators and petrol stations.

Another challenge that affects the availability and accessibility of charging infrastructure is the lack of standardization and interoperability among different charging systems and networks. Currently, there are various charging standards and protocols in different regions and countries, such as CHAdeMO, CCS, GB/T, Tesla Supercharger, etc. These standards differ in terms of their physical design, communication method, and data format. As a result, EV owners may face compatibility issues when they try to charge their vehicles at different stations or across borders. Moreover, charging networks may have different payment methods and membership requirements, which may create inconvenience and confusion for EV owners.

Cost and speed of charging

The cost and speed of charging are two important factors that influence the convenience and affordability of EVs. Charging cost refers to the amount of money that EV owners have to pay to charge their vehicles, which depends on the electricity price, the charging station fee, and the battery capacity and efficiency. Charging speed refers to the amount of time that EV owners have to spend to charge their vehicles, which depends on the power output of the charger, the battery capacity and state of charge, and the ambient temperature.

According to a study by BloombergNEF, the average cost of charging an EV in the US was $0.15 per kWh in 2020, which translates to about $10.5 for a full charge of a 70 kWh battery. The study also compares the cost of charging an EV with the cost of refueling an ICE vehicle, and finds that EVs are cheaper to run in most cases. For example, assuming a gasoline price of $2.4 per gallon and a fuel economy of 25 miles per gallon, an ICE vehicle would cost $16.8 to travel 280 miles, while an EV would cost only $10.5 to travel the same distance with a full charge.

However, while EVs may be cheaper to run than ICE vehicles, they are still slower to charge than ICE vehicles. According to a report by McKinsey & Company, the average charging time for an EV was about 50 minutes in 2019, while the average refueling time for an ICE vehicle was only about 5 minutes. The report also projects that the average charging time for an EV will decrease to about 30 minutes by 2030, but it will still be significantly longer than the average refueling time for an ICE vehicle.

Therefore, one of the key challenges for EVs is to reduce the charging time and increase the convenience for EV owners. Some possible solutions include increasing the power output and efficiency of chargers, developing new battery technologies that can charge faster and last longer, creating smart charging systems that can optimize the charging process and avoid peak hours, and integrating wireless or contactless charging methods that can eliminate the need for plugging in.

Policies and regulations

Policies and regulations are another factor that can affect the transition from petrol stations to EV charging stations. Policies and regulations can either support or hinder the adoption and diffusion of EVs and charging infrastructure, depending on their design and implementation. Some examples of policies and regulations that can support the transition include:

• Subsidies or tax credits for EV purchases or leases
• Subsidies or tax credits for charging station installation or operation
• Emission standards or targets for vehicles or fleets
• Bans or restrictions on ICE vehicle sales or use
• Zoning or parking rules that favor EVs or chargers
• Road pricing or tolling schemes that favor EVs or chargers
• Grid access or interconnection rules that favor EVs or chargers

Some examples of policies and regulations that can hinder the transition include:

• Taxes or fees for EV ownership or use
• Taxes or fees for electricity consumption or generation
• Subsidies or tax credits for petrol production or consumption
• Regulations or standards that limit the power output or compatibility of chargers
• Regulations or standards that limit the data sharing or interoperability of chargers
• Regulations or standards that limit the innovation or experimentation of chargers

Conclusion

In conclusion, EV charging stations will not replace petrol stations overnight, but they will gradually increase their presence and market share as EVs become more popular and affordable. The transition from petrol stations to EV charging stations will depend on various factors, such as the demand for EVs, the supply of charging infrastructure, the cost and speed of charging, and the policies and regulations that support
