Benefits
BREEZ ~Battery Range Extender EZ~

efficient

  • Double your miles per gallon and get over 100+ MPG on urban and highway driving.

environmental

  • Reduce CO2 & Greenhouse Gases Emissions by over 50%.

domestic

  • Reduce reliance on imported, finite resources and improve national security by replacing foreign oil with a domestic energy source. Less than 2% of U.S. electricity is generated from oil.

economic

  • Fill up for under $1. Driving costs drop to $0.02-$0.04/mile from $0.08-$0.20/mile for gasoline cars.

available

  • Use our existing and increasingly renewable electric grid without any new infrastructure.

unlimited

  • Never worry about ‘not having enough charge to get home’. With the BREEZ, you will never be stranded. When the BREEZ battery is depleted, you continue to drive as a regular hybrid vehicle.

convenience

  • Charge from any standard 110V/15A wall outlet at your work, home, or wherever there is an outlet.

  1. Fuel economy numbers from EPA, FHWA's National Highway Statistics
  2. Average number of miles traveled per year from EPA, FHWA's National Highway Statistics
  3. Average number of miles traveled per day from US Department of Transportation
  4. CO2e includes all GHG emissions: CO2, CH4, N2O, and HFCs (CH4,N2O, and HFC emissions represent roughly 5-6%of the GHGemissions)
  5. Calculated as [Pounds of CO2e/year (from gallons of gasoline) + Pounds of CO2e/year (from electricity)] divided by Annual Vehicle Miles Traveled
    Assumes 20.4 pounds of CO2e per gallon, from EPA, FHWA’s National Highway Statistics.
    Pounds of CO2e/year (from gallons of gasoline) is calculated as:
    [Annual miles traveled * pounds of CO2e per gallon / Vehicle MPG]
    Pounds of CO2e/year (from electricity) is calculated as:
    Total kWh used per year * state-level emission factor (pounds CO2e/kWh)
  6. Calculated as [Miles traveled per year] / [MPG]
  7. As compared to Prius + BREEZ’s average of 125 MPG in combined urban and highway driving.
  8. Cost is calculated as annual gasoline cost and annual electricity cost.
    Assumes average cost of $3.50 / gallon of gasoline and average off-peak charging rate of $0.08 / kWh.
    Annual gasoline cost is calculated as:
    [Gallons of Gasoline used per year * average cost of gasoline]
    Annual electricity cost is calculated as:
    [Miles per day / PHEV max range] * [max kWh pack size] * [Annual miles traveled / Miles per day] * [average off-peak $/kWh]
  • * One barrel of oil yields approximately 20 gallons of gasoline
