Deploying electric vehicles at scale will require the construction of a network of charging infrastructure, both public and private.
While a substantial portion of charging can be done overnight at home and during the day at the workplace, public charging options will provide drivers with added confidence and flexibility. The costs for public Level II (220/240V) electric vehicle supply equipment (EVSE) are highly dependent upon location, but hardware costs currently average less than $1,000 per unit. Level III direct current chargers used for ‘fast charging’ are significantly more expensive, but may provide a more conventional refueling option for customers in the near future.
Public charging stations will be needed to help with range anxiety, but the data available shows that most charging events happen overnight at residences. Therefore, public charging infrastructure should be installed in a thoughtful manner so that it maximizes people’s desire to use it and helps to minimize range anxiety in a cost-effective manner.
In order to support the development of a robust network of public and private charging infrastructure, the Coalition recommends:
- Make all infrastructure-related tax credits available at the point of sale
- Extend the existing tax credit for electric vehicle charging infrastructure through 2018 and expand the range of eligible costs to include upgrades performed by a utility to support fleet electrification and to facility owners for electrical power distribution equipment upgrades necessary to operate and monitor charging infrastructure.
- Modify building codes to require pre-wiring for 240-volt EVSE
