FAQS 4

How does ultra-fast charging affect the power grid?

However, the specific impacts on the power grid, such as the current and voltage distortions, peak load demand, voltage fluctuation, etc. of the unpredictable EV loads undergoing ultra-fast charging have not been thoroughly quantified.

How much energy does a power station generate?

The energy storage power station has a capacity of 70 MW/140 MWh. Based on calculations of charging and discharging 1.75 times per day, it can generate nearly 81 million kWh per year, equivalent to the electricity needs of 3.5 million users during peak hours in a day, reducing carbon dioxide emissions by over 45,000 tons.

Is ultra-fast charging a good idea for EVs?

One solution to overcome this obstacle is the use of ultra-fast charging (UFC) of EVs. UFC of EVs brings the charging time down significantly such that it becomes comparable with the refueling experience of conventional vehicles in gas stations. However, UFC comes with its share of negative impacts on the electric grid.

What are the different configurations of a fast/ultra-fast EV charging station?

There are two possible configurations of a Fast/Ultra-fast EV charging station: AC-Bus configuration and DC-Bus configuration . In the AC-bus configuration, each charger unit has a separate AC-DC rectifier and a DC-DC converter as shown in Fig. 1 (a).
