The state plans to take bids from charging station manufacturers this summer and select a contractor to do the installations in the fall. The state may want to reconsider the maximum 80-mile span between charging stations, though. Mainstream EVs like the Nissan Leaf and next year's Ford Focus Electric will only have a nominal range of 100 miles. At night, in the cold or in other non-ideal conditions the range will be considerably less. Level 3 stations will generally also not fully charge a battery. This is done to prevent over-charging and damaging the battery. That means the available range will be reduced further, so the charge stations should really be no more than 50 miles apart.
