Empowering Sustainable Mobility: The Role of Electric Vehicle Chargers

The way people power their vehicles is changing dramatically. Electric vehicles (EVs) are becoming more popular as battery technology continues to advance, making EVs more affordable and practical for everyday use. As EV adoption increases, so does the need for infrastructure to support these vehicles. Specifically, more public electric vehicle chargers will be required to give people confidence in long distance travel and to power the growing number of EVs on the road.

Types of Electric Vehicle Chargers

There are various types of electric vehicle chargers available, each with different power levels and charge times. The type of charger needed depends on several factors like the battery capacity of the EV and how quickly a charge is required.

Level 1 Chargers - Level 1 chargers provide charging through a standard 110-120 volt outlet. They are the slowest option, typically adding 2-5 miles of range per hour of charging. Level 1 chargers are best suited for overnight home charging.

Level 2 Chargers - Delivering power through 240 volt outlets, Level 2 chargers provide a medium charge rate. An Electric Vehicle Charger can gain 10-20 miles of range per hour of charging using a Level 2 charger. Many public charging stations and home charger installations use Level 2 technology.

DC Fast Chargers - Sometimes referred to as Level 3 chargers, DC fast chargers use high powered 480 volt or higher DC current to provide an 80% charge in 30 minutes or less. Fast chargers are ideal for public stations and highways to enable long distance travel. However, fast charging does degrade batteries more quickly over time compared to slower Level 1 or 2 charging.

The Need for More Charging Infrastructure

In order for widespread EV adoption to take place, a robust public fast charging network is essential. Range anxiety, or the fear of an EV running out of charge away from home, is a major concern for many considering switching from gasoline vehicles. Simply put, people need to know public chargers are conveniently located along major roadways and routes to allow comfortable long distance driving.

While the United States has seen expansion of charger deployment in recent years, the infrastructure remains inadequate compared to needs. A study by the International Council on Clean Transportation estimates the U.S. will require about 43,000 fast chargers by 2030 in order to support increasing EV sales. Currently there are less than 5,000 fast chargers publicly available nationwide.

Regional leaders and laggards are emerging based on charging infrastructure development. States like California, which has seen the most EV adoption, are proactively adding chargers across cities and highways. Meanwhile, other parts of the country are lagging in providing a reliable network. As new EV models launch, chargers must be ready well in advance of demand to inspire consumer confidence.

Challenges and Advancing Technology

Deploying thousands more chargers presents both logistical and technical challenges. Locating and permitting stations, particularly along major routes, requires planning and cooperation between governments and stakeholders. The electrical grid will need upgrades in some areas to accommodate increased charging load without straining local distribution systems. Standardization of payment systems among charging networks is another ongoing issue.

Technology continues to evolve, promising more efficient and consumer friendly options. "Bidirectional" or "vehicle-to-grid" capable EVs may one day provide energy storage services that benefit the grid during high demand periods. Dynamic or "intelligent" charging aims to optimize station usage and load management. Faster charging techniques like 350kW are entering use cases beyond taxis and fleets. Advances in battery composition and ultrafast charging could eventually enable fueling times comparable to gas vehicles.

The Switch is On

With ambitious targets to electrify transportation, major automakers are committed to rolling out new EV models at an unprecedented pace over the next 5 years. governments are responding with incentives, regulations and infrastructure mandates necessary to support electrification goals. As battery and vehicle technology maturation drives down costs to the point of mainstream affordability, adoption will accelerate rapidly. The next decade will see an explosive growth in electric vehicles on roads worldwide. Building out a widespread, reliable, fast charging network is crucial to satisfying consumer demand for long range transportation freedom. Investments made today will help pave the way for the electric transportation revolution of tomorrow.
