While there is not a one-size-fits-all solution for a workplace charging program, there are a number of resources available to help employers design, implement, and manage the right program for their organization.
Assess Demand for a workplace charging program
Employers considering whether workplace charging is right for their organization will want to start by assessing employee demand with an employee survey (https://energy.gov/eere/vehicles/downloads/sample-employee-survey-workplace-charging-planning). Once this assessment is complete, employers may set goals for meeting workplace charging demand, either by planning to meet the entire need (i.e., all drivers that have expressed or will express interest in PEV charging) or by dedicating a percentage of parking spaces to PEV charging. For example, Google has a goal to dedicate 5% of all parking spaces to workplace charging.
Procure and Install
Employers should determine what types of charging stations to purchase. There are a few decisions to make, including the following:
- Charging Level: There are benefits and drawbacks to both Level 1 and Level 2 charging stations in the workplace. Employers must evaluate which option is best for their facilities. For more information about the differences between charging levels and their merits for workplace charging, see the U.S. Department of Energy’s (DOE) Workplace Charging Station Basics page (https://energy.gov/eere/vehicles/workplace-charging-station-basics).
- Networking: Charging station networks provide maintenance, customer service, and energy monitoring capabilities, and collect payment on behalf of the station owner. However, networks require a fee, and employers will need to consider whether the convenience of charging networks outweighs the financial cost. For more information, see the DOE’s Workplace Charging Level 2 page (https://energy.gov/eere/vehicles/level-2-charging-workplace).
Employers should also be sure to get quotes from a number of charging station providers. For more guidance, see the DOE’s Workplace Charging Sample Request for Proposal document (https://energy.gov/eere/vehicles/downloads/request-proposal-guidance). Employers will work with their electrical contractor to determine charging station placement; station installation can be an expensive process, but employers can minimize costs by siting stations in locations that require minimal trenching, boring, and electrical panel upgrades. For more information about siting and installation, see the DOE’s Workplace Charging Equipment and Installation Costs page (https://energy.gov/eere/vehicles/workplace-charging-equipment-and-installation-costs).
Manage your workplace charging program
A well-managed, well-planned workplace charging program can ensure station access to all employees, promote strong communication between employers and station users, and encourage responsible station use.
- Registration and Liability: Many employers require employees to register their PEV, which allows the employer to identify the number of vehicles using their charging stations. For example, employers can give registered vehicles a mirror hangtag or window sticker that identifies the vehicle as having permission to use the charging stations. A registration form may also include language that requires vehicle owners to agree not to hold the employer responsible for any damage to the vehicle that occurs while it is parked at the charging station. For more information, see the DOE’s Workplace Charging Registration and Liability page (https://energy.gov/eere/vehicles/workplace-charging-management-policies-registration-liability).
- Station Sharing: It is important to emphasize that workplace charging is a privilege, not a right. Employees may be obligated to share stations with their colleagues and comply with established charging time limits. While an employer can set up systems for sharing stations, such as reserving the station (similar to how an employee would reserve a conference room) or establishing a set schedule for use, most employers allow users to resolve station-sharing conflicts themselves. However, it is important to establish consequences for violating station policies, such as using a station for less than four hours. By framing workplace charging as a privilege, an employer reserves the right to restrict access for employees that routinely violate company policy. For more information about how to establish workplace charging policies and encourage station sharing, see the DOE’s Workplace Charging Station Sharing page (https://energy.gov/eere/vehicles/workplace-charging-management-policies-sharing).
- Pricing: While most employers offer workplace charging for free, charging for station use can be a good way to manage demand. Employers may charge for electricity (e.g., per kilowatt hour) or for time (e.g., per hour), depending on preference and applicable regulations. Employers can motivate employees to move their vehicles and share the stations by charging a nominal fee (or no fee) for the first set number of hours (e.g., four hours) and then raise the fee for subsequent time that the vehicle is parked in the space. For more information, see the DOE’s Workplace Charging Pricing page (https://energy.gov/eere/vehicles/workplace-charging-management-policies-pricing).
