Installing Charging Stations

When you have decided to install charging stations, call one of our electric vehicle advisors and we’ll help you review your charging plan. We’ll also discuss the installation process and address any considerations that are unique to your business. The equipment and rate options you select will determine what kinds of electrical upgrades will be required. You’ll need an Electric Vehicle Supply Equipment (EVSE) installer or qualified electrician to inspect your business, upgrade your wiring and panel as needed, install your new equipment, and obtain required city permits and inspections. Afterward, we will inspect and, if necessary, upgrade the electrical service equipment that connects your business to the electric grid.

Equipment Types

As you plan for electric car charging, you’ll find a range of equipment available. Some basic models simply enable safe charging, while other types come outfitted with options like credit card-payment technology and programmable timers. In addition to equipment, you’ll find that Electric Vehicle Supply Equipment (EVSE) manufacturers and vendors offer installation, maintenance, and other services for monitoring and managing your energy use and costs. You can find third-party resources to help you choose the right equipment manufacturer on our Tools & Resources page.

Equipment Costs

The cost of charging equipment varies widely by model, and the method of installation depends on your existing infrastructure and the equipment you select. Contact the equipment manufacturer and a qualified electrician for a quote. You may qualify for federal, state and local rebates and incentives to help subsidize your costs.
