The electric vehicle (EV) market is experiencing unprecedented growth, creating a strong demand for EV charging infrastructure. As an electrician, you can capitalize on this trend by expanding your service offering to include EV charging station installation. This guide provides vital information and resources for electricians becoming EV charging station installers.


The Growing Demand for Electric Car Charging Stations

In 2023, global electric vehicle sales reached a record high, with over 10 million units sold. This represents a 35% increase compared to 2022, highlighting the rapid adoption of EVs by consumers and businesses alike. Projections for 2024 show that EV sales will continue to rise, potentially exceeding 12 million units. With this surge in EV ownership, the demand for reliable and accessible charging infrastructure has never been greater.


In the United States, the number of public charging stations grew by 24% in 2023, reaching roughly 130,000 charging stations nationwide. This growth is fueled by both federal and state-level incentives that promote the development of EV infrastructure. For example, the U.S. government has allocated billions of dollars in funding through programs like the National Electric Vehicle Infrastructure (NEVI) Formula Program, which aims to install 500,000 public chargers by 2030.


Residential, Commercial and Public EV Charging Installations

Understanding the differences between the three types of EV charging installations is crucial for customizing your installation services to meet your client's needs and project requirements. 


Residential EV Chargers

Homeowners are increasingly installing home Level 2 EV chargers. These residential projects provide cost-effective and convenient charging solutions for everyday use. For these projects, you’ll help homeowners integrate EV charging into their daily routines seamlessly.


Commercial EV Charging Installations

You can tackle various projects in the commercial sector, from small-scale setups for companies or condominium complexes to extensive installations for businesses, shopping centers, and office buildings. Commercial installations often involve working with business owners to provide scalable and efficient charging solutions that meet the needs of employees, customers, tenants, or company fleets and can include multiple charging stations and advanced features.


Public EV Charging Stations

Public charging installations are high-visibility projects in shopping malls, transit stations, highway rest stops, or public parking areas. These projects require you to understand and implement accessibility standards and manage high-volume use to ensure that the charging stations are both user-friendly and reliable. Your role will involve designing systems that accommodate frequent use and adhere to regulatory requirements.


Opportunities for Electricians Installing EV Chargers

As the EV market expands, so does the need for skilled professionals to install and maintain electric vehicle supply equipment (EVSE). By diversifying your services to include EV charger installation, you can tap into a lucrative market that offers numerous benefits:

  • Increased Revenue: The average cost of installing a Level 2 home charger ranges from $800 to $2,500, depending on factors like the distance from the electrical panel and the complexity of the installation. Commercial EV charging station installations often exceed $10,000. Adding EV charger installation to your service offerings can significantly boost your income.

  • Business Growth: Expanding your skill set and service portfolio can attract new clients, including homeowners, businesses, and municipalities looking to install EV charging stations.

Understanding EV Chargers

When considering expanding your services to include EV charger installations, it’s crucial to understand the different types of chargers available. There are three main levels of EV chargers, each with its own characteristics and suitable applications. Keep in mind that charging time also varies depending on the battery capacity and charge level of the vehicle.


Types of Electric Car Charging Stations

EV charging station equipment fits into three general categories.

  • Level 1 EV Chargers

  • Description: Level 1 chargers use a standard 120-volt AC outlet typically found in homes, so no electrical work is needed for these chargers.

  • Charging Speed: They provide a slow charging rate, adding about 2-5 miles of range per hour.

  • Applications: Best suited for overnight residential charging, plug-in hybrid vehicles with small batteries, or locations where vehicles will be parked for extended periods.


  • Level 2 EV Chargers

  • Description: Level 2 chargers use a 240-volt AC outlet, similar to some large appliances like dryers and electric water heaters.

  • Charging Speed: They offer a faster charging rate, adding about 10-60 miles of range per hour.

  • Applications: Commonly installed in homes, workplaces, and public locations. Ideal for daily use and can charge most EVs in several hours.


  • DC Fast Chargers

  • Description: These chargers use direct current (DC) to deliver high power quickly, making them ideal for long-distance trips. Because of their high cost, they are primarily installed for high-use applications.

  • Charging Speed: They can add 60-100 miles of range in just 20 minutes.

  • Applications: Typically found in commercial and public charging stations along highways and busy routes. DC fast chargers are ideal for quick charging during long trips or while running errands. The electricity cost per kilowatt hour is often greater at DC fast chargers compared to Level 2 charging stations.


Key EVSE Components and Technologies

Understanding the components and technologies involved in EV chargers is essential for proper installation and maintenance. Here are the primary components you’ll encounter:


Types of EV Connectors

  • SAE J1772 Connector

  • Usage: Commonly used for Level 1 and Level 2 charging in North America.

  • Compatibility: Works with most EVs except Tesla without an adapter.

  • Combined Charging System (CCS)

  • Usage: Used for DC fast charging.

  • Compatibility: Widely adopted by American and European automakers.

  • CHAdeMO

  • Usage: Used for DC fast charging.

  • Compatibility: Commonly used by Japanese automakers such as Nissan and Mitsubishi.

  • Tesla Connector

  • Usage: Used for both Level 1, Level 2, and DC fast charging (Superchargers).

  • Compatibility: Specifically designed for Tesla vehicles, but adapters are available for other EVs.


Electrical Infrastructure Requirements for EV Chargers

  • Power Supply: Adequate electrical supply is crucial for charging stations. For Level 2 chargers, a dedicated 240-volt circuit is typically required. In contrast, DC fast chargers need significantly more power and may require three-phase power, which makes it more difficult to install these chargers in certain areas.

  • Site Assessment: Conducting a thorough site assessment helps determine the necessary electrical upgrades and infrastructure for installing electric car chargers.


By familiarizing yourself with these types and components of EV chargers, you’ll be better able to advise clients on the best options. Because the connectors on EVs vary, EVSE must be compatible with the specific vehicle model. 


EV Charging Station Installation Training and Certification

As the EV market expands, the need for proficient and certified electricians to install and maintain EV charging stations becomes increasingly critical.
