Electric Charging Toolbox
Why is Electric Vehicle Charging important to us?
OTO’s long range transportation plan Destination 2045 sets a goal to build a transportation system that supports a resilient region that is prepared for the future, specifically to maintain environmental quality, develop resiliency to external factors, manage congestion, and plan for electric vehicles and other upcoming technologies. This vision was shared by local leaders and the public which described the scenery and the natural environment as the top strength of the region’s transportation system, as well as identifying electric vehicle planning as an opportunity to address the region's needs.
As a center for regional and national travel, the region should also plan to provide a convenient EV infrastructure network. This allows people to use the highway network to travel to their destination without concerns for where they need to stop to complete their journey. This toolbox will provide local municipalities, private enterprises, and the public with a basic understanding of electric vehicle charging and resources on how to plan for future needs.
Electric Charging Basics
-
There are different types of Electric Vehicles that use electricity in various ranges to improve vehicle efficiency.

BEVs and PHEVs are considered Plug-In Electric Vehicles (PEVs) because they can be fueled fully or partially through electricity. The driving range of PEVs depends on the manufacturer and model of the vehicle and also the driving behavior. The average range of Electric Vehicles is between 200 and 300 miles on a fully charged battery and the average American household drives around 50 miles per day. A comprehensive list of electric vehicles can be found on the website of the U.S. Department of Energy - Alternative Fuels Data Center under "Availability of Electric Vehicles."

Charging Infrastructure varies depending on the available electric infrastructure. Currently most PEV owners do the majority of their charging at home, which mostly provides a lower supply of voltage and amperage and thus has longer charging times. Public facilities aim for faster charging with different levels of power available.
What is an Electric Vehicle Charging Station?
An electric vehicle charging station is a designated location where electric vehicles (EVs) can recharge their batteries. These stations are commonly found in various public places, such as parking garages, shopping malls, and along highways, allowing drivers to easily access charging while on the go.

In this context, a charging station is called a "location." This means it’s a specific site that has one or more electric vehicle service equipment (EVSE) units. For example, a mall parking lot might have several charging stations, each able to power up different vehicles.
Port
The "port" refers to the charging unit itself that provides electricity to one electric vehicle at a time. This means that if multiple cars arrive at a charging location, they will each need their own charging unit to charge simultaneously.
Connector
A connector is the physical piece that connects an EV to the charging station. It can be a socket or a cable. Each charging unit may have different types of connectors, like CHAdeMO or CCS (Combined Charging System). However, only one connector can be used at a time, so drivers need to choose the right one for their vehicle.
In summary, an electric vehicle charging station includes the location, the charging unit (port) that supplies power, and the connector that links the vehicle to the charging station. This infrastructure is essential for making it easy for everyone to use electric vehicles.
Overview of Charging Equipment
Charging equipment for plug-in electric vehicles (PEVs) is grouped by how quickly it charges the batteries. Level I and II charging use alternating current (AC) charging, which means an electric current that reverses its direction many times a second on regular intervals. Fast Chargers use direct current (DC) meaning an electric current that flows in only one direction and thus allows faster charging through constant voltage. The below table shows some of the differences of the different charging levels.
Please click on the image, to view the full image with a mobile device or tablet. Charging ranges and speeds depend on multiple factors, including battery level, vehicle type and manufacturer, charging station, and weather. A battery will charge faster when it has a lower state of charge and slows as it reaches full capacity. Level I and Level II charging stations maintain relatively consistent charging speeds, however DC fast charging stations are typically most rapid between 20% and 60%, with speeds slowing significantly between 80% and 100%. The installed batteries from different manufacturers also have different maximum allowable charging rates, meaning that a station might offer a higher kilowatt (kW) output than then the maximum input of the car, thus the vehicle charge time might be longer due to the vehicle type. Lastly the outside temperature can slow down the charging speed. Electric vehicle batteries prefer temperatures not being too cold or hot. For example, the charging of a battery creates heat and the battery thermal management system (BTMS) prevents the battery from overheating and will slow down the charging speed if the battery gets too hot.
A note on connector types:
The shown connector types are the currently common connectors in North America. There are adapters available for all connector types to connect to other systems. However, EV manufacturers have agreed to adopt the North American Charging Standard (NACS) and starting in 2025 or 2026 all new vehicles will be equipped with NACS.

Equipment and Installation
The installation costs of an EV charging port depend on the charging level of the port(s) and the existing infrastructure. In 2024, the estimated costs for the equipment for a residential Level 1 charger is about $300 to $600 and for a residential Level 2 charger around $500 to $700. These costs are only for the charging equipment, while the labor costs can be up to $1,000. Equipment for commercial Level 2 charger costs between $8,000 to $10,000 for a charger with two ports. DC fast chargers cost around $70,000 to $150,000 for a charger with two ports. Additional costs for the installation can vary widely based on the location and the existing infrastructure. For example, some sites will require the installation of a transformer as well, which can cost $5,000 or more.
Maintenance
Maintaining charging stations involves securely storing cables, regularly checking parts, and keeping the equipment clean. Chargers may need occasional repairs, and warranty costs differ by manufacturer. Maintenance can be low-key, but fixing broken chargers can be expensive if they’re out of warranty. It’s crucial to clarify who pays for maintenance—whether it’s the site host, charging network, or installer. Maintenance contracts should specify response times and uptime requirements. On average, owners should expect to spend about $400 to $1,000 a year per charging port on maintenance, depending on the charger type and if it's connected to a network. Depending on your funding source there also may be maintenance and reporting requirements which have an effect on the costs.
Fees
The costs for the electricity depends on the responsible utility provider and it is important to include the utility provider early in the planning phase for the installation of EV charging infrastructure. The local utility provider is an important partner that can help provide information regarding installation and operation costs. The common pricing structure for charging users include by kilowatt hour (kWh), by session, by length of time, or through a subscription. In 2024, DC fast charging prices per kWh range from $0.24 to $0.70 in the OTO area with idle fees of $15 to $20 per hour for vehicles staying connected and parked in the charging spot longer than half an hour after completing charging. Level 2 charging prices range from $0.18 to $0.23 in the OTO area in 2024. Some locations offer free charging or take a flat fee for charging per hour or per spot. For more information on current pricing visit websites like plugshare.com, which provide information on pricing, charging speeds and availability of locations and also offer reviews from other users.
Planning ahead
Many electric vehicle (EV) owners charge at home, while currently most charging stations are built by private companies. This puts the responsibility on local municipalities to create accessible public EV infrastructure for everyone, including renters, travelers, and business fleets that need frequent charging.
In the Springfield metro area, the small number of EV owners presents an opportunity for better planning of future growth. Local municipalities can encourage employers and private developers to integrate EV charging options in office spaces and new multi-family housing projects. This includes planning for EV parking spots that won’t take away from other residents and ensuring they are close to existing electric infrastructure or can access existing electric infrastructure easily.
Additionally, municipalities can develop public EV charging options in on-street parking and public lots near commercial areas, parks, and government buildings.
The below map gives an overview of available and planned charging stations in the OTO area. It can also be used to plan for future public EV infrastructure projects by showing current infrastructure, demographic data, and multi-family housing density. The Alternative Fuels Data Center also provides an EV Infrastructure Toolbox, which offers resources for estimating charging Infrastructure needs.
