Document Type and Number:
WIPO Patent Application WO/2019/192420
Kind Code:
A1
Abstract:
An extended-range-type fuel cell electric car power device and a control method therefor, the device comprising: a driving motor (1), a bidirectional converter (2), a chopper (3), a power cell (4), a fuel cell (5), a high-pressure hydrogen storage tank (6), an electric control valve (7), a controller (8), an accelerator pedal (9) and a brake pedal (10). An output of the driving motor (1) is connected to a transmission shaft of an electric car by means of a speed change gearbox, and an input of the driving motor (1) is connected to an alternating current output end of the bidirectional converter (2); a direct current input end of the bidirectional converter (2) is connected in parallel to an output of the power cell (4) and an output of the chopper (3), and an input of the chopper (3) is connected to a power source output of the fuel cell (5); a fuel inlet of the fuel cell (5) is connected to an output of the high-pressure hydrogen storage tank (6) by means of the electric control valve (7); and an output of the controller (8) is connected to a control port of the electric control valve (7) and a control port of the bidirectional converter (2) respectively, and an input end of the controller (8) is connected to output signals of the accelerator pedal (9) and the brake pedal (10) respectively. The control method uses a BP neutral network for control.
