The EV charging station in this study is meticulously designed to feature eight 60 kW DC fast charging piles, a configuration that aligns with the current dominant trend in Taiwan’s EV charging infrastructure.
Solar-and-energy storage-integrated charging stations typically encompass several essential components: solar panels, energy storage systems, inverters, and electric vehicle supply equipment (EVSE). Moreover, the energy management system (EMS) is integrated within the converters, serving to regulate the power output.
Furthermore, the utilization of energy storage with EMS for real-time charging and discharging scheduling allows for the effective control of the wholesale store’s electricity consumption within a lower contracted capacity, thus further reducing the charging station’s electricity costs.
Author to whom correspondence should be addressed. Under net-zero objectives, the development of electric vehicle (EV) charging infrastructure on a densely populated island can be achieved by repurposing existing facilities, such as rooftops of wholesale stores and parking areas, into charging stations to accelerate transport electrification.
According to the system design, the energy storage device has a capacity of 300 kW/800 kWh. Taking into account the depth of discharge (DoD) of the lithium-ion battery, the SOC is set to be between 20% and 90%.
The primary objective of the control strategy is to manage the power requirements of the charging station, ensuring optimal use of grid electricity while adhering to contracted capacity limits. In this phase, if the charging station requires power, the demand is initially met by the grid.
