A method of operation for a hybrid energy storage system, the method comprising:
- charging an energy storage bank of the hybrid energy storage system using a flyback converter of the hybrid energy storage system, the energy storage bank comprising a plurality of lithium-ion hybrid ultracapacitors;
- determining whether an electrical voltage of the energy storage bank is above a predetermined threshold;
- responsive to determining that the electrical voltage of the energy storage bank is above the predetermined threshold, shutting off the energy storage bank;
- responsive to determining that the electrical voltage of the energy storage bank is not above the predetermined threshold, providing direct current (DC) power from the energy storage bank;
- and
- converting DC power from the energy storage bank to alternative current (AC) power at an inverter of the hybrid energy storage system.
