Abstract [eng] In the world there is rapid advance in electric vehicles and with the advance there are more and more problems associated with this industry. It is a big problem in this area with the electricity accumulation and use. The aim is to increase possibility for electric vehicles to travel the greatest possible distance with the lowest possible energy consumption. This requires a high capacity batteries and adequate control algorithms. Bad selection of control algorithms may lead to unnecessarily wasted batteries accumulated energy reserves and reduce the range of traveled distance. This paper provides an overview of the most common system control algorithms, such as PID controller, speed profiling and fuzzy logic. After review of each of these methods use cases in the scientific literature, it was decided to create automatic speed control system for electric train designed to reduce energy consumption on the basis of speed profiling. The paper also reviews wireless systems management techniques with Bluetooth. The paper describes both the hardware and the software system development processes. The developed system is automatic and the initiation and collection of data is only done remotely. The system has been experimentally tested in the power consumption and after that compared with the previous system power consumption. The comparison showed that the new system is capable to sustain fluent movements of the electric train model and can reduce energy consumption.
