摘要

This paper presents the results of research into the application of an active battery switching system in the drivetrain of a prototype electric vehicle. The system's purpose is to increase the drivetrain's electrical efficiency especially in the partial-load range. Efficiency is increased using a switching unit that allows the vehicle's traction-battery circuitry to be changed during operation and thereby adjusting the intermediate circuit voltage stage to that actually required. The system consists of three electronic switches, which allow two different voltage stages in the intermediate circuit. This paper presents further results of roller dynamometer test series with the active battery switching system. The focus is thereby put on efficiency measurements in driving cycles.
