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.
