The development of a system for charging electric vehicles with alternating current in the mining industry

This article shows the trend of increasing the number of electric traction vehicles at mining facilities and notes the importance of ensuring a high-quality and safe process of charging onboard batteries in difficult conditions of mining enterprises. The development of special technical means is proposed, both for the purposes of testing charging stations during mass production, and during their inspection and maintenance at operating enterprises. The development of a simulation model of an alternating current charging system “charging station-electric vehicle”, made in the MATLAB application software package and designed to debug all functions provided for by GOST R IEC 61851 and SAE J1772 standards, is presented. When compared with the requirements regulated in the standards, it is concluded that the sequence of actions performed, signal parameters, time intervals between states in the simulation model fully meets these requirements. Based on the simulation model, the hardware and software parts of the laboratory research facility were developed, in which the power part and the control system of the charging station, as well as a system emulating the operating modes of an electric vehicle were implemented. Software that allows testing the operation of charging stations to verify compliance with the requirements of current standards has been implemented. It can be finalized in accordance with industry regulatory documentation, which is important for facilities with increased safety requirements, which include mining enterprises.
