User Need Based Charging Strategies for Electric Vehicle

Electric vehicle (EV) users require a flexible charging strategy that adapts to their needs. In routine scenarios, users can opt for normal charging, which enhances battery longevity and efficiency by delivering power at a controlled rate. However, in emergencies or time-sensitive situations, users can select fast charging to quickly replenish the battery and resume their journey with minimal delay. In case of vacation mode, users can provide their EV need of use time and date so that the charging system will delay the charging accordingly to avoid the calendar aging due to idle time of EV with high State of Charge. To demonstrate the effectiveness of this strategy, a MATLAB simulation has been developed to model both normal, fast and delayed charging modes for a 320 V, 94.5 Ah Tata Nexon Indian eV Car.
