Electric vehicle fast charging station with solar energy system and its method

摘要

A high power EV fast charging station with solar energy system (EVFCS-SES) having a HV DC bus, several EVFCS-SES cells connecting in parallel, and a storage battery is operated as either a solar energy generation system, or a solar energy generation plus a direct storage battery charger, or as a high power EV fast charger with solar energy/storage battery/AC grid power, or a PWM rectifier battery charger to perform EV battery charging and solar energy generation for AC grid power.
