A novel and useful hybrid fast charging system for electric vehicles incorporating an efficient hydraulic storage and regeneration system (ESRS) that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to charge an accumulator array with high pressurized oil. Subsequently, energy is released rapidly in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, to power one or more fast charge circuits. The output mechanical power supplied is used to supply electricity to one or more EV charging stations. The rapid discharge of the accumulators is sufficient to generate electricity at a high enough power to charge one or more electric vehicles relatively quickly with either ac or dc current, e.g., 350 kW for 10 minutes at 400 VDC or higher. Relatively low power supplied by the grid (utility) can be used to run an electric motor to charge the accumulators between discharges. In addition, the fast charge circuit can aggregate electricity generated by the ESRS with grid power to meet the high power requirements for fast charging EVs.
