System and method for hybrid power backup using graphene based metal air battery

A stationary power backup system comprising;

• a main power source, and wherein the main power source comprises a primary metal air battery, and wherein the primary metal air battery is a graphene-based metal-air battery (GMAB) for generating electrical power;
• one or more auxiliary power source connected to the main power source for receiving and storing the generated electrical power for supplying to a load;
• an electrolyte flow management system to regulate a circulation of electrolyte through the cells of the primary metal-air battery module;
• an electrolyte characteristics management system to maintain a temperature of the electrolyte within a desired limit or pre-set range or threshold level through a heating-cooling mechanism/system;
• a real-time monitoring and feedback system to regulate the temperature, flow, power and energy of the overall system;
• electronic power control system comprising a switching circuit, DC-AC inverter, DC-DC converter, and DC-DC charger;
• and
• Hydrogen Harvesting/Collection System to store the hydrogen gas produced during the operation of primary metal-air battery;
• wherein the one or more auxiliary power sources are charged with the electrical power generated from the GMAB to supply electrical power to a load and wherein the one or more auxiliary power sources are connected to the load through the switching circuit, and wherein the output of the auxiliary power source is fed to the load through an inverter, and wherein one auxiliary power source is in a charging condition with the electrical power from GMAB, while the other auxiliary power source is in a discharge condition to supply power to the load at any instant, and wherein a state of charge—SoC (which relates to the amount of power left in the battery) is monitored continuously, and wherein the auxiliary power source supplying power to the load is cut off with the help of switching circuit, and the second auxiliary power source, under charging condition with the power from GMAB, is switched on to supply electrical power to the load and the first auxiliary source is charged with the power from GMAB, when the auxiliary power source reaches a pre-set SoC level.
