Operating Modes of a Two-Unit Fast Charging Station for Electric Vehicles
Abstract
For the development of electric vehicles, both in Russia and abroad, it is necessary to create an extensive network of efficient electric charging stations. One of the factors restraining the spread of electric charging stations is the limitations on the consumption current and area of the installation, which are determined by the existing infrastructure. An electric charging station containing two power units was studied. Taking into account the identified limitations and current capabilities, operating modes of an electric fast charging station were proposed that provide simultaneous charging of two electric vehicles with minimal downtime. These modes were tested by computer modeling using the MATLAB/Simulink software package and experimentally tested at the EDISON60 fast charging station. Compared to existing modes, the proposed solution allows to reduce the time of simultaneous charging of two electric vehicles by up to 23% with a given limitation of consumption current from the three-phase infrastructure network, taking into account the possible maximum output current of the power modules. The presented material is intended for developers of electric charging stations with increased throughput.
