A system for extending a range of an electric vehicle includes a graphene-based metal-air battery system (GMABS), an electrolyte management system (EMS), a flow management system (FMS), one or more auxiliary power sources, and a real-time monitoring and feedback system (RMS). The GMABS includes multiple cells electrically connected to each other and filled with an electrolyte for initiating a reaction to generate power. The EMS regulates a temperature of the electrolyte flowing through the cells. The FMS regulates a circulation of the electrolyte in the GMABS. At least one auxiliary power source is connected to the GMABS to receive and deliver the power to components of the electric vehicle. The RMS continuously computes and monitors a state of charge of each auxiliary power source in real time to facilitate a continuous power delivery to the electric vehicle, thereby extending the range of the electric vehicle.

Embodiments of the invention relate to an open metal-air fuel cell system capable of uninterrupted supply power, which relates to the field of metal-air fuel cell stacks and comprises a sensing subsystem, a controller, a circulating filtration subsystem, an electrolyte solution tank and several open metal-air fuel cell units. Open metal-air fuel cell units are sequentially arranged within the electrolyte solution tank, and each open metal-air fuel cell unit is connected with each other in parallel. An air electrode of the open metal-air fuel cell unit has a tank structure, and the trough structure has a concave surface upwards. The sensing subsystem is arranged within the electrolyte tank. The electrolyte solution tank is connected with a circulating filtration subsystem. The controller is used for controlling a circulating flow of the circulating filtration subsystem depending on electrolyte solution temperature information collected by the sensing subsystem.
