Abstract

Electric Vehicle (EV) technology has advanced to allow bidirectional power flow, enabling EVs to not only consume energy but also supply it back to the grid. However, research on time-based charging and discharging patterns is limited, particularly in Indonesia, where electricity tariffs remain constant throughout the day. This study proposes a time-based control strategy, assuming
dynamic pricing with higher rates during peak hours, to create mutual benefits for EV users and utilities. The system integrates a State of Charge (SoC) management mechanism and a Proportional-Derivative (PD) controller to optimize battery performance and energy flow. Tests at initial SoC levels of 25%, 55%, and 85% reveal that the parameter combination Kp = 0.02 and Kd = 1 achieves the lowest
error, ensuring efficient control. This strategy encourages EV users to sell energy during peak hours, providing financial rewards while helping utilities balance energy demand during critical periods.
