An electric vehicle battery charger based on the Faraday disk generator is developed in this paper to reduce the amount of time it takes for the rotational energy to be converted into electrical energy. The kinetic energy of the generator during charging is transformed effectively into electric energy by rotating the compact formed from the disk permanent magnet and conducting shield by means of an electric motor supplied from the power grid using possibly renewable energy sources. One of the advantages of the Faraday disk generator is its high power capability, which is applicable for high rate of charging and reducing the amount of time it takes for the rotational energy to be converted into electrical energy. Computer simulations have been performed for various sets of the charger element parameters and after selecting the obtained results, the optimal set was established. Simulation results for charging processes corresponding to the optimal element parameter tests are included.
