PV Sourced Battery Management System with IoT Based Real Time Monitoring System for Electric Vehicle

In this work, the solar fed EV battery charging application is proposed with battery energy management strategy (BEMS) and monitored through Internet of Things (IOT) in which the data over the power generation by PV source, load consumption and energy stored in battery. The SEPIC converter provides load regulation while the bidirectional DCDC converter provides the charging and discharging of battery in following modes of operation, 1. PV provides supply to Load and Battery (peak irradiation), 2. PV provides supply to only Load (medium irradiation) and 3. Battery provides supply to Load in the absence of PV source (Lower irradiation). The proposed controller operates the devices according to the loading arrangements and amount of available PV power. The simulation work is carried out using PROTEUS software. It is validated and verified with an experimental setup as the readings are taken throughout a day for power generation, load demand and battery status which covers all the modes and control the switching devices with the Arduino control.
