In specific energy saving measures, special attention is paid to driving technologies, as electric drives account for two thirds of industrial energy consumption. Paper deals with appropriate selection of electric motor with higher efficiency for shuttleless weaving grapple machine in order to retrofitting the electric drive. Such machines are not single pieces, but are always a certain set of a given production company. Once electricity consumption is reduced by investing in energy-saving engines, this can be the basis for intelligent and efficient energy management, accurate predictions of electricity consumption for future periods, which ultimately leads to increased energy efficiency of manufacturing enterprises.and systems.

Paper deals with general overview of the electric vehicles on-board chargers, available in operation – both for new such vehicles and for those that have been obsolete, but are still moving on the roads in our country and around the world. Studies have been conducted and useful information on battery-powered electric vehicles and plug-in hybrid electric vehicles has been systematized. All this is done in connection with the ubiquitous decisive steps for large-scale and global introduction of electric vehicles, such as appropriate choice and necessity and the related topics for drastic change of the car fleet, which will cover firstly urban vehicles, the energy balances of power grids of the individual countries with a careful analysis of the expected load for normal operation, the environmental benefits, the energy efficiency and economic benefits from the use of electric vehicles and their technical improvement in the long run. In addition, under good management, the development of electric mobility can be one of the ways for achievment of employment and industrial growth.

Paper deals with specifics of converting a conventional car into an electric one. The main stages of the conversion process are dealt concise but thorough. The findings are the basis for launching a large scale project with the necessary duration and financing, as a result of carrying out the necessary development activities and experiments will proceed to the development of a prototype, which will ultimately be realized. The overall focus is on research and application in the students’ learning process.
