Does the outdoor power supply have DC fast charging

DC fast charging stations have become the leading charging option when fast charging speed is required. The cost of charging EVs with DC fast charging can vary considerably because of the non-linearity of the charging power and comparatively higher costs of charging than the domestic charging setup.

A fast-charging station should produce more than 100 kW to charge a 36-kWh electric vehicle's battery in 20 min. A charging station that can charge 10 EVs simultaneously places an additional demand of 1000 kW on the power grid, increasing the grid's energy loss .

Literature associated with the DC fast chargers is categorized based on DC fast charging station design, optimal sizing of the charging station, CS location optimization using charging/driver behaviour, EV charging time at the station, and cost of charging with DC power impact on a fast-charging station.

TABLE 1. DC charging levels. As DC charging systems are primarily designed for use in outdoor stations, they require suitable wiring. They are more efficient, allowing for faster charging. In reality, modern charging stations transform DC voltages to levels more suited for EV battery packs.

Overall, fast-charging stations exhibit a higher usage rate compared to public Level 2 charging stations, with Fast DC stations displaying a utilization rate nearly three times higher than AC charging points [19, 20]. There are three types of chargers available: Level 1, Level 2, and Level 3.

It is divided into a number of categories, including DC fast charging station design, optimal sitting, and sizing of the charging station, CS location optimization using charging/driver behaviour, DC power impact on fast charging station, EV charging time at the station and cost of charging.
