Large Manufacturer

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.”
