Infrastructure for Portable Power

The problem with electric cars is and always has been range issues. Most of America is laid out in a way that we are very car dependent. While public transportation, walking, biking, and current electric vehicles can meet much of the daily needs of the average American, there are still times when people want to be able to go more than the range of one charge. To allow this to occur, America must install an infrastructure for portable power. There are two primary means of charging electric cars, the first is simply to plug into homes, offices, and parking garages. PHEVs and EVs connected to the electrical grid can be used as an efficiency and emergency power measure, providing power when the grid is down and also absorbing power at off peak times and being able to release it at on peak times, increasing the efficiency of the grid. This would require beginning to design homes, offices, and parking lots/garages with dedicated car charging ports. This electricity at work places and parking lots could be paid for with a monthly service or by KWh, like a parking meter. The other method of charging would involve next-generation PHEVs and EVs with removable batteries that are going to allow for swapping of batteries at service stations, much like propane tanks. These stations would act like current gas stations and would allow for an essentially unlimited range.
Metrics: What it is:
  • Number of charging locations and their locations

Where we get it:

  • Follow the following projects:
  • GM partnership with the Electric Power Research Institute
  • Project better place in Isreal, San Francisco, and 25 or so other countries
  • Portland
  • UK: EDF and recharging station producer Elektromotive
  • Coulomb \"ChargePoint Network\" and \"Smartlet Charging Stations\"

How often it's updated:

  • Hopefully frequently
