  • Comes with every electric vehicle
  • Plug directly into a standard 120-volt outlet
  • Can serve employees who do not require faster refueling

Level Two

  • Typically found along major highway corridors

Where to Install EV Charging

EV chargers can easily be located in parking lots and garages. When evaluating your parking lot for charging station installation, selecting a location near existing electrical infrastructure will reduce costs and installation complications. Also, remember to plan longer-term for future employee EV adoption to save on design and construction costs. Other expenses we can help you consider are equipment, maintenance and energy needs.

How Many to Install

To best understand how many EV chargers to install, consider the following questions:

  • How many employees/customers drive electric?
  • Do you plan to electrify your fleet?
  • How many EVs do you anticipate needing to accommodate over the next five years? 

Create a Charging Policy

Organizations can benefit from setting clear guidelines around usage, sharing and pricing to help ensure a safe and successful charging experience for employees. For example, some companies prefer employees to pay for electricity, while others consider it an employee benefit and do not require employees to pay for charging. To develop your charging policy, consider engaging your employees in the effort to understand their charging needs fully. Here is an example of a workplace charging policy (PDF) by the U.S. Department of Energy.

Once charging stations have been installed, continue to communicate with employees to educate them on how they can best take advantage of this new benefit.
