Advanced Automotive Technology: Visions of a Super-Efficient Family Car

TABLE 4-8: Computation of Incremental Costs and RPE

for 2005 Mid-size EV

Component | Size | Cost basisa | Cost/price |

Battery (lead acid) 34.9 kw-hr $150/kw * 34.9 kwh $5,240

Motor/controller 105.9 kw $300 + (30/kw * 105.9 kw) 3,480

Electric power steering.. $65 65

Heat pump air conditioner | .. | $300 | 300 |

Total electric system -- -- 9,085

Engine 125 kw $400 + $18/kw * 125 kw 2.650

Transmission | 5-spd auto | $300 + $2/kw * 125 kw | 550 |

Emission controls Evap + Exhaust $300 300

Net savings -- -- 3,500

Total variable cost (v) | -- | -- | 5.585 |

Unit fixed investment (F) See appendix B^900

RPE -- (1.4 v+F) * 1.25 10.900

aThe costs are much lower than current costs and include the "learning curve” effects for batteries, motors, and controllers. Battery charger

cost not included.

KEY: RPE = retail price effect.
