Welcome to 2023, where the electric vehicle market is thriving like never before! Regardless of where you are in the world, you can't help but notice the surge of EVs on the road. This year's growth has exceeded all expectations, setting a new standard for what's possible in sustainable transportation. There are two significant factors driving the shift towards electric vehicles (EVs) in the automotive industry. Firstly, an increasing number of automakers are introducing new EV models and are actively promoting them, leading to a rise in consumer awareness and interest in these vehicles. As a result, EVs have now become a viable option for many new car buyers. Secondly, governments across the world are considering a shift towards zero-emission vehicles (ZEVs) as a means to decarbonize their transportation sectors. This move comes with a strong support for both OEMs and consumers in terms of favorable policies and subsidies to make and buy EVs. If we look at some numbers to gain perspective, the sales of electric cars across the globe in the first quarter of 2022 hit 2 million, up 75% from the same period in 2021.
While these numbers are optimistic and encouraging, the state of EV charging infrastructure remains a big hurdle in the large-scale adoption of EVs. The lack of adequate charging stations is causing what is known as 'range anxiety' among existing and potential EV owners.
The Current State of EV Charging Infrastructure in the U.S.
According to the U.S. DoE's Alternative Fuels Data Center (AFDC), there are over 100,000 charging stations in the U.S. as of 2022. A quick analysis of the AFDC data tells us that over 25% of them are located in California and the rest of them are scattered across the country.

While this may sound like a significant number, it is still not enough to meet the growing demand for EVs. According to a report by the National Renewable Energy Laboratory (NREL), the U.S. needs 9.6 million public charging ports to support 50 million EVs by 2030. To support the growing demand for charging stations, the Biden-Harris Administration announced a new plan of action that sets a course for achieving the national goal of building a national network of 500,000 electric vehicle chargers along America’s highways and communities by 2030. The Bipartisan Infrastructure Law has pledged USD 7.5 billion in EV charging, USD10 billion in clean transportation, and over USD 7 billion in EV battery components, critical minerals, and materials. Along with several other initiatives, the government on February 15, 2023, signed a partnership with Tesla, Inc. to enhance the network of EV chargers in the U.S. Through this partnership, Tesla has agreed to open a portion of its U.S. Supercharger and Destination Charger network to non-Tesla EVs, making at least 7,500 chargers available for all EVs by the end of 2024. These chargers will be accessible to non-Tesla drivers through an app and at an additional cost. Many in the industry wonder why Tesla has agreed to open up its exclusive charging network to its competitors. Tesla's Super Charger network is one of its key value propositions that provides it with a competitive advantage. So, what's in it for Tesla? An in-depth analysis of the charging stations data from AFDC could help answer the question. But first, lets talk about connectors!
The Question of Connectors
Challenges in the charging infrastructure industry are not just limited to the number of accessible stations. There is more to it. One of the biggest obstacles facing the EV charging infrastructure is the lack of standardization. There are currently different types of charging stations with different connectors. Compare it to the different chargers that we have for Android and iOS devices, if you will. There are also different charging speeds, with some stations offering fast charging and others only providing slow charging. This makes it difficult for EV owners to charge their vehicles conveniently.
The most common classification of charging infrastructure is based on the rate at which vehicles can be charged, once plugged in. The EV chargers are broadly divided into Level 1, Level 2 and DC Fast Chargers. Level 1 chargers offer approximately 5 miles of range per 1 hour of charging. They use the J1772 connector and comprise of less than 2% of the total chargers in the U.S. as a result of their inefficiency. Over 80% of the public charging ports are Level 2 chargers which offer about 25 miles of range per hour of charging. They offer up to 30 Amps, delivering 7.2 kW of power, making them popular at most home, public and workspace charging stations. These chargers also use the J1772 connectors. It is important to note that Tesla vehicles have a unique connector that works for all their charging options, including their Level 2 Destination Chargers and chargers for home. All Tesla vehicles come with a J1772 adapter, which allows them to use non-Tesla charging equipment.
The third type is the Direct-current fast charging (DCFC) equipment (typically a three-phase AC input) that enables rapid charging along heavy traffic corridors at installed stations. The AFDC data analysis shows that just over 15% of all EV chargers in the U.S. are DCFCs, with Tesla owning most of them (over 19,000) as of 2022. This monopoly in the DCFC space might have encouraged the company to open its charging network to non-tesla vehicles. It is believed that Tesla will charge a premium rate for other vehicles to utilize the Supercharger network. The quick rise in adoption of electric commercial vehicles such as buses, delivery trucks and long-haul trucks presents Tesla with an opportunity to capitalize on its Supercharger network and increase its market share and revenues in the EV charging industry space.
At the end of the day, partnerships between the government and private charging network providers are a big win for EV adoption in the U.S. With the proposed plans and investments, we can hope to see a significant improvement in the EV charging infrastructure in the coming years. It is time to spark conversations about EV charging infrastructure and work towards a sustainable future.
