- Electric vehicle charging stations typically include an input power source from the public grid, energy storage from BESS systems, generator backup systems, etc., and an output power source for charging vehicles such as cars, trucks, and buses. These are charging stations with medium power ranging from 40-60kW to fast or ultra-fast charging stations with power up to 200kW or higher.
- The power source from the public grid can be directly from a 3-phase 4-wire low-voltage grid or from a 22kV medium-voltage source with a charging station load exceeding 30kW. Low-voltage transformers in this case may include oil-insulated or dry-type transformers, depending on the design space of the charging station area.
- The solution provides a complete set of substations and charging stations, aiming to optimize the investment efficiency of customers in the business of providing charging services for electric vehicles, and to popularize safe, economical, and highly efficient electricity usage solutions.
