Abstract: The concept of a smart charging regulator, a novel technology designed to enhance battery efficiency and extend lifespan through intelligent control mechanism. Traditional charging techniques frequently fail to adapt to changing conditions, resulting in overcharging / undercharging or exposure to unfavourable working situations, all of which can harm battery health. The smart charging regulator is a potential improvement in battery management technology, providing a holistic approach to optimizing efficiency and lifespan. Uncoordinated charging of Electric Vehicles (EVs) can cause voltage fluctuations, power outages, and incremental overloads, all of which are taxing and damaging to the distribution networks. In this paper, a new method to minimize the cost of charging electric vehicles based on the Day-Ahead Electricity Price (DAEP) is proposed on taking battery degradation cost, taking into account the EVs' maximum power charger, state of charge (SOC) limits. The full charging of the EVs' batteries at the end of the charging period, and the distribution feeder subscribed power is analysed. Additionally, the EVs' initial SOC uncertainties are evaluated using their daily mileage. Lastly, a single-phase Low Voltage (LV) distribution network with an EV penetration rate of 50% and 100% has been installed in a residential area to demonstrate the effectiveness of the suggested strategy. In this paper, the linear programming approach is used to address the optimization problem. The findings demonstrate that, in comparison to uncoordinated EV charging, the suggested strategy can lower EV charging costs by 50% and 38% for 100% and 50% of EV penetration rate, respectively.

Keywords: battery efficiency, lifespan, volage fluctuations, cost of charging, linear approach.
