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 with their universal battery interfaces, and a storage battery system provides the following functions: solar energy generation; solar energy generation plus a direct storage battery charging; high power EV fast charging with either solar energy or storage battery or AC grid power. These functions enable EVFCS-SES system to charge any EV battery with solar energy in minutes, convert solar energy to AC grid power, and supply electricity to building loads at same time. In addition, it stores unused solar energy into storage battery for supplementing solar energy in cloudy days or at night. Combining EV fast charging system and solar energy generation system into one system achieves a low cost, high efficient and high power EV fast charging station with solar energy generation system. Furthermore, this system takes full advantage of solar energy and eliminates or reduces AC grid power usage effectively. As a result, it makes both EV fast charger and solar energy generation system more desirable and economical.
An EV Fast Charging Station with Solar Energy System (EVFCS-SES) maximizing solar energy usage to charge EV battery in minutes and produce building electricity, said system comprising:
An optimized solar energy method to reduce utility bill, the said method comprising minimum AC grid power import means through charge/discharge storage battery to maximize solar energy and minimize AC grid power usage during on-peak hour period.
A EV fast charging station with solar energy generation along with the method of maximizing solar power usage for EV battery charger and building loads by means of storage battery and unique system configurations of an EVFCS-SES system comprising:
