The use of electric vehicles is increasing day by day since more and more people are aware of the impact of the negative effects of internal combustion engines on the environment. The automotive industry is therefore focused on the production of electric vehicles, which should be equivalent to conventional vehicles. For the perfecting of electric vehicles it is necessary to constantly test and analyse them. Because we need certain data for the analysis, the thesis describes the manufacturing process and the description of the measurement system for determining the efficiency of an electric vehicle. The vehicle in our case is a reduced remote vehicle, with alternating synchronous electric motors with permanent magnets on the rotor. Based on the measurement chain, components are used to capture the necessary measuring signals, the operation of which is also presented in more detail. Our implementation of the measuring system is useful in the case of accelerated movement due to the method of measuring mechanical power.
