EXTENDED-RANGE ELECTRIC VEHICLE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/134180
Kind Code:
A1
Abstract:
Provided is an extended-range electric vehicle, comprising: a driving system, which comprises an electric motor A (2) serving as a driving electric motor, and wheels (1) coaxially connected to the electric motor A (2); a battery system (11), which is electrically connected to the electric motor A (2); an energy recycling system, which comprises an electrically controlled clutch (3), an air compression pump A (5) and a high-pressure gas bottle (6); and a range extender, which comprises a micro gas turbine and a power generator (18) that are connected to each other, wherein the micro gas turbine comprises a rotary shaft, a gas compressor (19), a combustion chamber (20), a turbine (21) and a heat regenerator (24), and may further comprise at least one thermal element (25), the thermal element being connected to the power generator (18). Further provided is a control method for an extended-range electric vehicle. The high-pressure gas bottle (6) is taken as an energy balancer to recycle braking energy of a vehicle, potential energy is stored by means of air compression, energy loss is avoided, and thrust can be provided for the vehicle when the vehicle needs to speed up; and the heat regenerator (24) and the thermal element (25) are provided, thereby further improving the energy utilization rate, and also ensuring safe shutdown of the micro gas turbine.
