Cost Performance Estimating Relationships for Hybrid Electric Vehicle Components

摘要

This report documents hybrid electric vehicle (HEV) component cost performance estimating relationships (CPER) developed by Science Applications International Corporation (SAIC) for the Office of the Deputy Assistant Secretary of the Army for Cost and Economics under contract DASW0l-97-D-0061 (Delivery Order 6). These CPER are tools that support cost estimation of HEV components. While this technology is still developing, recent advances make it likely that future military vehicles will contain HE systems. This technology is a significant departure from the power package and drive train technology seen on current generation vehicles. Estimation methods based upon these older technologies would miss important insight into the current state of technology. These estimating tools develop methodologies for energy storage components, drive system components, and a supplemental armor solution. Using these, cost estimates for different combinations of components can be generated. This provides the basis for cost comparisons among those alternative configurations. It does not include the traditional vehicle components such as the frame, weaponry, C41, wheels or tracks, crew stations, NBC, or special equipment. Separate estimates of these other vehicle systems would be combined with the hybrid electric system estimate to arrive at a vehicle cost estimate. The report is divided into three sections. Section 1, which encompasses chapter 1, provides the organization of the report and outlines the general methodology used to collect the data and develop the estimates contained in this report. Section II, encompassing chapters 2 through 5, describes the primary designs for hybrid electric power designs and provides estimates for the individual components of a hybrid electric vehicle system. Section III, which includes chapters 6 and 7, provides additional considerations for the cost estimation and modeling of hybrid electric vehicles.
