Pearson Prentice Hall - Upper Saddle River, NJ FIGURE A smart phone can be used to link On-Star in the Chevrolet Volt, which can send state-of-charge and estimated range information.

34 15 General Motors Hybrid Vehicles Hybrid and Alternative Fuel Vehicles, Third Edition James D. Halderman © 2013 Pearson Higher Education, Inc. Pearson Prentice Hall - Upper Saddle River, NJ FIGURE After the Volt has been charged it uses the electrical power stored in the high-voltage battery to propel the vehicle and provide heating and cooling for 25 to 50 miles (40 to 80 km). Then the gasoline engine starts and maintains the SOC between 25% and 35%. The gasoline engine cannot fully charge the high-voltage batteries but rather the vehicle has to be plugged in to provide a higher SOC level.

35 15 General Motors Hybrid Vehicles Hybrid and Alternative Fuel Vehicles, Third Edition James D. Halderman © 2013 Pearson Higher Education, Inc. Pearson Prentice Hall - Upper Saddle River, NJ FIGURE (a) The Chevrolet Volt is charged using a standard SAE 1772 connector using either 110 or 220 volts. (b) After connecting the charging plug, a light on the top of the dash turns green and the dash display shows the estimated time when the high-voltage battery will be fully charged and the estimated current range using battery power alone.
