The selection of modern drives requires very high precision testing facilities. Different ways to measure the efficiency of drives for electric vehicles are evaluated. The main topic of this evaluation is the accuracy of the measurement. In this paper a high precision, computer controlled test bench to measure the efficiency of electrical drives as a function of torque, speed and supply voltage is described. The influence of the type of battery on the efficiency of the drive can be measured. Drives can be tested up to a maximum speed of 10000 rpm and a maximum power of 100 kW. Detailed measurements will be presented about the efficiency of drive systems. This data is used to compare different drive types and to optimize them. The measured values will serve as a database for a simulation software to calculate the energy consumption of electric vehicles under various conditions.
