With electric vehicles (EVs), drivers can enjoy a longer driving range than with conventional vehicles. However, EVs have a lower charging capacity than their fossil fuel counterparts. This leads to congestion on roads when EV drivers need to recharge their cars at night or during the day as they drive long distances between home and work. In this article, we will take a look at how congested roads become with limited charging capacity of an EV, especially in major urban centers or city corridors where there are high numbers of EVs with limited battery capacity. We will also see how congestion worsens as the number of EVs increases with limited charging capacity and what measures can be taken to alleviate the issue.
What causes congestion in cities?
EV charging stations are an important part of an EV infrastructure that enables longer driving ranges, but the fast charging station is even more important. Fast charging stations with a charging capacity of at least 50% can be a savior for EV drivers during long commutes. The charging capacity of the average home charging station is around 22%, and a large number of EVs with this capacity would create traffic jams when a large number of them are in the area for charging. The same problem would arise if everyone in the city suddenly wanted to charge their car at night. EVs with limited battery capacities would also experience congestion if there is a sudden increase in the number of EVs with limited battery capacity that need to charge at night or during the day. This is because at times of slow demand on the grid, EV drivers are incentivized to charge their cars, leading to congestion. During peak hours, EV charging stations can also be overburdened when there is high demand on the grid, which leads to congestion.
EV charging infrastructure required to reduce congestion
EV charging stations with a large charging capacity are required to reduce congestion on roads by EV drivers. A large number of charging stations of different sizes is required to ensure that a large number of EVs can charge at any given point in time. Furthermore, charging stations are also required in locations with low access points such as parks and public spaces so that owners of EVs can charge their vehicles when they park their cars in those places. To further reduce congestion on roads due to EV charging, it is also important for EV drivers to charge their cars at daytime hours. The charging capacity of a car at night is very less, and the demand on the grid is also very low. If everyone in the city suddenly wanted to charge their cars at night, the grid will become extremely overburdened and could collapse.
Spread awareness about fast charging facilities
The prime reason why EV drivers have a limited charging capacity is that they rarely use the home charging station and prefer to charge at public stations. This behavior can be changed by spreading awareness among EV owners about the benefits of using the home charging station. Awareness can be spread through various channels such as online forums, social media posts, and awareness-building events. During the awareness-building events, information such as the location of the charging station, the average charging time, the average charging cost, the access time, and the access cost should be collected and shared with the community.
Smart road infrastructure for efficient and seamless travel
The road infrastructure is being revolutionized to enable smart driving with the use of sensors and road analytics. Sensor-enabled intersections that help EV drivers make smooth transitions from one road to another are becoming a norm. Traffic lights can be made sensor-enabled to enable smooth transitions from one lane to another. Sensor-enabled traffic signals can also be used to optimize the travel time for EV drivers. Sensor-enabled road markings such as lane markings, speed markings, and turn markings can be used to inform EV drivers about the best path on their journey.
Conclusion
EVs are becoming more popular, but they have a limited charging capacity. This means that when EV drivers need to charge their cars, they form traffic jams on the roads. This can be alleviated by installing charging stations at homes with large charging capacity and also by encouraging EV drivers to charge their cars at daytime. These measures will help reduce the congestion on roads due to the limited charging capacity of EVs.
