Abstract:
1. A power system of a series hybrid vehicle, comprising: a fuel source; a control system; at least two auxiliary power units, wherein each of the 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, wherein each of the auxiliary power units comprises: a power battery electrically connected to the 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; 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 it into mechanical energy and transmit the mechanical energy to a power train of the vehicle so as to drive the vehicle to run; and an AC grid-connection device, which converts the corresponding AC electrical energy outputted by the respective auxiliary power units into corresponding alternating currents at the same voltage, the same frequency and the same phase with each other and outputs them to the common current bus.
