CENTRALIZED CHARGING STATION
First Claim
1. A Centralized Charging Station (CCS) for rapid charging and discharging of electric vehicles (EVs) comprising:
- a. a power converter unit (PCU) comprising;
i. a bidirectional converter for converting an input AC supply to an output DC voltage and converting an input DC voltage to an output AC supply; and
ii. a master control unit (MCU) for regulating operations of the bidirectional converter, the MCU providing a communication interface for the CCS;
b. one or more vehicle interface power converter units (EVPCUs) coupled with the PCU and one or more vehicle interface units (VIUs) for charging and discharging of one or more EVs, each EV being connected to the EVPCU via a VIU; and
c. a storage unit interface module (SUIM) coupled with the PCU and a battery storage unit for fast charging and discharging of the battery storage unit;
the battery storage unit being used for recharging one or more EVs under predefined conditions;
the CCS being capable of charging a first set of EVs and discharging a second set of EVs simultaneously.
