A power system of a series hybrid vehicle, comprising a fuel source; a control system; at least two auxiliary power units, each of which auxiliary power units, under control of the control system, independently receives fuel from the fuel source, and converts chemical energy in the fuel into electrical energy and outputs the electrical energy to a common current bus; a power battery electrically connected to a common current bus to, under control of the control system, receive electrical energy from the common current bus to perform charging or perform discharging through the common current bus; and a traction motor electrically connected to the common current bus to, under control of the control system, receive electrical energy from the common current bus and convert the electrical energy into mechanical energy and transmit the mechanical energy to a power train of the vehicle so as to drive the vehicle to run. |
