This document discusses workplace electric vehicle charging options for employers. It provides examples of charging installations at different companies and considerations for choosing charging levels and fees. The key points are: - Employers can choose between Level 1, Level 2, or DC fast charging, with Level 2 being suitable for employees parking 1-4 hours and fast charging for under an hour. - Examples include free Level 1 charging, a fee-based Level 2 network, and dedicated fleet spaces. - Employees generally prefer lower or no fees, while faster charging requires higher costs to install and maintain the equipment.

5. • Started with Level 1 with no fee.
– Many users, not enough room for all
– Some not charging at home because work
was free
• Switched to Level 2 with a fee
– Less users
– Typically only those that need to charge
• Some with PHEV complained that the
fee was too high
– Typical driver comment: “I’m not opposed to
paying, but prefer to charge at level 1, so I
don’t have to move my car during the day. I
expect the fee to be similar to home charging
or at least less than gas.”
