Charging Station Equipment & Installation

Getting Equipped & Installed

Whether you’re the proprietor of a small eatery, the office manager of a large corporation, or a property manager, we’re here to help if you’re considering incorporating electric vehicle charging into your business. Read on for the basics about charging equipment, installation, and charging levels.

Charging: Levels & Times

Currently there are 3 charging levels—or voltages—for charging electric cars. As you might expect, higher voltage levels charge batteries faster, but often require additional investments in equipment and wiring upgrades. For a quick view of the different available charging levels, speeds and estimated equipment costs, check out our comparison chart.

The Installation Process

When you have decided to install charging equipment, call one of our energy advisors to discuss your charging equipment and rate options, which will determine any necessary electrical upgrades to your building. You’ll need an Electric Vehicle Supply Equipment (EVSE) installer or qualified electrician to inspect your business, obtain required city permits and inspections, upgrade your wiring as needed, and install your new equipment. Afterward, we will inspect and, if necessary, upgrade the electrical service equipment that connects your business to the electric grid.

Picking Out Equipment

You can choose from a range of available electric car charging equipment, from basic models to stations outfitted with options like electronic payment technology and programmable timers. In addition to equipment, manufacturers and vendors often offer installation, maintenance, and other services for monitoring and managing your energy use and costs. Ready to choose a model and manufacturer? You can find help choosing the right equipment vendor on our Tools & Resources page.

Cost Considerations

Your investment in electric car charging will fall within a wide range, as the price of charging equipment varies by model, and the cost of installation depends on your existing infrastructure, planned location for charging stations, and the equipment you select. Contact your equipment supplier and a qualified electrician for a quote. You may also qualify for federal, state and local rebates and incentives to help subsidize your costs and help you make the upgrade.
