Problems solved by technology
[0003] Based on the research results of energy recovery technology for electric vehicles and micro electric vehicles, the idea of applying these technologies to auxiliary braking of automobile retarders / runners came into being. Traditional retarders / runners can be divided into different types according to their working principles. Eddy current, hydraulic and permanent magnet types, especially for eddy current retarders / movers, may burn out due to excessive heat generated

The invention relates to an automobile braking energy recovery slowing method and a system thereof, which utilizes the braking energy recovery of the automobile retarder / runner to generate electricity, and connects the retarder / runner brake power generation device in series with the gearbox and the first transmission of the automobile Between the shafts, there is an electric motor in the retarder / traveler braking power generation device, and a power conversion device is connected to the motor. The power conversion device is connected to a generalized load. The electric motor generates electric energy to supply power for the auxiliary power supply of the car body or generalized loads. The invention can convert the braking kinetic energy of the automobile into electric energy, store and utilize it, provide a new energy source for the vehicle, and utilize the previously unused braking energy of the vehicle, especially for the auxiliary power supply capacity of the automobile. Significant significance; the system has the advantages of simple structure, fast response, convenient modification, easy installation, etc., especially suitable for alternating power drive mode, and can be used in various vehicles such as automobiles and electric vehicles.
Description
technical field [0001] The invention relates to a method and a system for slowing down an automobile, in particular to a method and a system for slowing down by recovering braking energy of an automobile. Background technique [0002] The working principle of motor energy recovery is to convert the braking torque into electric energy by using the motor as a generator to realize energy recovery of kinetic energy. At present, this method has been widely used in the braking energy recovery of electric bicycles, electric tricycles, micro electric vehicles, and electric vehicles, and has achieved good results. The kinetic energy of the car body is converted into electric energy to supply the battery or super capacitor, which not only achieves the effect of providing braking torque, but also improves the mileage of the electric car. At the same time, it can also supply power for the auxiliary power supply of the car body, saving energy, and has great advantages. High economic val...
