Study on Battery Charging Strategy of Electric Vehicles Considering Battery Capacity

This paper proposes an improved fast charging strategy for electric vehicles (EVs) by considering available battery capacity. According to previous research and experiment reports, the energy capacity of batteries is not fixed, it can decrease temporarily depending on magnitude or discharging power. addresses decreased in proportion power which leads a reduction driving range. For effective practical use EV users, change expressed through equation, new state charged indicator proposed. To improve conventional method that uniformly supplies regardless capacity, this optimal injecting constant The proposed provides reference minimize costs energy, time, usable loss based billing system charging. verify effectiveness method, each calculated characteristics, total cost compared. results show performance minimizing both reduced economic burden users.
