2011 MIT Energy Conference EV Infrastructure Panel
Electric Vehicle (EV) charging is expected to take place primarily in homes in the near-term. But, even today, EV owners would benefit from chargers at office buildings, garages, and public locations, and widely available charging infrastructure might alleviate range anxiety concerns and encourage second-stage adopters to buy EVs. Much of the charging infrastructure that has been deployed is heavily subsidized by the Federal government. Is there a profitable business model for public charging, or must it continue to be subsidized by the government for the foreseeable future? Do electric utilities have a role to play in the deployment strategy?
The growth of charging infrastructure will have an effect on the electrical grid. In the short term, potential problems may be localized to hot-spots of EV penetration. But in the longer term, when will utilities and regulators need to plan for the load growth? How can utilities, regulators, EV manufacturers, and other stakeholders work to address the potential problems, and are there regulatory barriers or technical issues that will need to be overcome? To what extent is future smart grid technology required for deployment of charging infrastructure?
