Electric Vehicle Charging Installations
Incentives from government, utilities and electric vehicle charging installations companies can help offset the costs of installation. In addition, the installation of EV chargers can increase workplace loyalty and demonstrate sustainability commitments.
As an electrician, following the NEC and Occupational Safety and Health Administration standards is important for your safety while performing EV charging installations. In addition, securing the proper permits and scheduling inspections are critical.
Cost
Many factors impact the upfront cost of installing an EV charger, including the type and level of charge, labor rates in your area, installation supplies like conduit and wiring, and any complexities involved with the project. The best way to estimate the total cost of an EV charging station is to work with an experienced, local electrical contractor who can conduct a thorough site assessment, prepare a detailed plan of action and install your charge stations.
Home charging stations can be hardwired directly into a garage or an existing 240-volt outlet, but larger installations may require additional electric system upgrades and a new service panel with a dedicated 240-volt breaker. Other considerations include cable length, whether a charger will be used for multiple vehicles, and any requirements for trenching or drilling if the installation location is outside of a garage.
Some electricity providers offer rebates on smart WiFi-enabled EV chargers and on home wiring upgrades needed to accommodate them, and federal tax credits for plug-in EV drivers are available to reduce the up-front costs of installation.
Benefits
As EV ownership increases, businesses and property owners are looking for ways to make charging available to employees and customers. Onsite charging stations are seen as premium amenities that can increase customer loyalty, demonstrate sustainability commitments, and support workforce retention. They can also help businesses save money on energy costs by eliminating demand charges and reducing the need for fuel.
Proper placement of EV chargers can also ensure maximum usage and availability. Aim for locations that are easy to access, unobstructive, and close to the building. In addition, minimizing the distance between the power source and the charging station can help lower installation costs. Running power to EV chargers through surface mounted conduit or through soft landscaping can also be cost effective.
Additionally, EV drivers should be provided with signage that allows them to easily locate chargers and prevent conventional vehicles from occupying them. This will help improve EV charging equity, especially in areas with lower EV adoption rates.
Technology
The charging station uses an assembly of electrical connectors and sensors to transfer energy from the grid to a vehicle. The system can also communicate with the vehicle to determine how much electricity is needed and monitor the EV’s battery status. The technology enables fast, convenient and safe EV charging.
There are several EV charger installation models, including repurposing telecom boxes in Scotland and pole-mounted systems that use streetlight infrastructure. Some of these models are ENERGY STAR certified and meet ADA and ABA accessibility standards.
Some EV chargers allow users to pay for the power they consume using a credit or debit card. Others allow the vehicle owner to select a payment method through a smartphone app. EV charging stations can also incorporate smart grid features, such as communicating with the electricity grid to limit service during peak demand. They may even support vehicle-to-grid scenarios that enable the EV’s battery to supply energy to the grid during times of high prices.
Installation
In many states, electrical work on EV charging stations must be performed by a licensed electrician and must comply with local codes and standards. The process of obtaining permits and inspections can add to project timelines.
The existing electrical capacity of your property and the location of the charger will significantly impact installation costs. For example, if the charger is located far from your home’s main electrical panel, an electrician may have to upgrade your entire electrical system or run new wiring. These upgrades can significantly increase your upfront costs.
You should also factor in any labor costs for the actual installation of the charging station equipment. An experienced electrician can install an EV charger quickly and efficiently, reducing the total cost of your project. This will allow you to start providing EV charging services sooner and attract more customers and employees.
