The invention provides a power system and a control method thereof. The power system comprises a controller, a gas supply device, a throttle valve and a battery pile. The control end of the gas supplydevice is electrically connected with the first control end of the controller, and the control end of the battery pile is electrically connected with the second control end of the controller. The throttle valve comprises a throttle valve body, a motor and a valve plate, the valve plate is arranged in a gas channel of the throttle valve body, a first port and a second port of the throttle valve body communicate with the gas channel, the control end of the motor is electrically connected with the controller, and a rotation shaft of the motor and the valve plate are in transmission connection. The gas output end of the gas supply device communicates with the gas inlet end of the battery pile, and the gas outlet end of the battery pile communicates with the first port of the throttle valve body. The controller drives the motor, the motor is used for driving the valve plate to rotate, the flow of gas supplied to the battery pile through the gas supply device to be combusted and exhausted is controlled, and through control over the gas backpressure, the combustion conversion efficiency of the fuel is effectively improved.
Description
technical field [0001] The invention relates to the field of dynamics, in particular to a power system and a control method thereof. Background technique [0002] With the continuous growth of the national economy and the improvement of people's living standards, the use of automobiles is becoming more and more common. According to the global demand for energy and power, more users use new energy vehicles with relatively less environmental pollution. The power system of new energy vehicles is mostly a fuel cell. During the use of the fuel cell, when the fuel of the fuel cell is burning, the gas delivery flow is fixed and cannot be adjusted. The combustion conversion efficiency of the fuel is low, which shortens the service life of the battery. . It can be seen that the existing power system has the technical problem of low fuel combustion conversion efficiency. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a pow...
