In the U.S., 6.7% of all light duty vehicles sold in 2022 were electric vehicles.
Costs are cheapest when installing an EV charging station during renovation or construction of a new building or parking lot.
More EV charging stations are needed to meet anticipated demand.
In 2022, 918,464 plug-in electric vehicles (EV) were sold in the U.S., 6.7% of all light duty vehicle sales (ANL 2022). This is a 45% increase over EV sales in 2021. The federal government and automakers have aimed for EVs to make up 50% of vehicle sales by 2030 (US 2022).
About 36% of Americans plan to buy an EV for their next vehicle (Bartlett 2022). The primary barrier for those not planning to buy an EV is concerns about EV charging. The average range for EVs in 2020 was 260 miles (DOE 2021).
EV Charging Stations. There are three types of EV charging ports (Table 1). Level 1, level 2, and DC fast charge (DCFC) charging ports charge EVs about 5, 25, and over 200 miles of range per hour, respectively (Brown 2022).
There are currently 50,133 public charging stations in the U.S. and 128,924 individual public charging ports (DOE 1 n.d.).
Typical EV charging station locations include homes; tourist destinations; businesses such as hotels, grocery stores, and restaurants; transportation facilities, including airports and park-and-rides; and community sites such as libraries, schools, business districts, and curbside parking spaces.
Two analyses have estimated future EV charging station needs and their results differ based on assumptions of future EV sales (Woods 2017; McKenzie 2021). The U.S. has met from 17%-41% of level 2 charger needs and 11%-100% of DCFC charger needs. However, 61% of all DCFC ports in the U.S. are on the Tesla network and only accessible to Teslas (DOE 1 n.d.).
The Bipartisan Infrastructure Law established the National Electric Vehicle Infrastructure Formula Program (NEVI) to provide $7.5 billion to states to build a network of 500,000 EV charging stations around the nation. The Missouri Department of Transportation already has a plan approved through NEVI and plans to open requests for proposals in 2024.
Charging station costs depend on several factors including the power it delivers; type of charger; the number of charging ports; and the presence of communication, data collection, and billing features (Table 1; Smith 2015).
Installation costs can vary greatly (Table 1). Some factors that can increase installation costs include laying or connecting electric supply conduits, upgrading the electrical capacity to run the charging stations, and meeting Americans with Disabilities Act requirements (Smith 2015).
Soft costs, such as the cost of meeting building codes and obtaining utility connections and local building permits are some of the largest opportunities for reducing costs (Nelder 2019).
Maintenance costs for charging stations include regular checking of parts, cleaning, and occasional repairs (DOE 2 n.d.). Repairing broken chargers may be expensive if they are no longer under warranty. Owners should plan for $400 per charging station per year for maintenance.
Usage fee structures that are commonly used include charging per kWh, by session, by time, or a subscription (DOE 2 n.d.). Session and time fee structures are common in states where non-utilities are not allowed to sell electricity. More than 25% of public charging stations are free.

|Charger Type||Miles of Range Added per Hour||Equipment Cost||Installation Cost (per unit)||Average Installation Cost (per unit)|
|Level 1||∼5||$300-$1,500||$0 - $3,000||Not Available|
|Level 2||∼25||$400-$6,500||$600 - $12,700||~$3,000|
|DCFC||200-400+||$10,000 - $140,000||$4,000 - $66,000||~$21,000|
