Automobile deceleration inertial kinetic energy recovery system and method

Abstract

The invention discloses an automobile deceleration inertial kinetic energy recovery system and a method. The system comprises a gear recognition sensor, an automobile speed sensor, an original automobile generator pressure sensor, an accelerator position sensor, a brake signal sensor, an electric energy storage device, a controller, an electric energy storage device management module and a display. The method includes that an original automobile engine is connected with a switch of the electric energy storage device by the controller under the condition that an automobile gear position signal, an automobile speed signal, a generator output voltage signal, an accelerator position and a brake signal meet set requirements, the engine which is dragged by inertia of an automobile drives a generator to charge the electric energy storage device under monitoring of the electric energy storage device management module, simultaneously, the display can display charging and discharging conditions, accordingly, inertial kinetic energy is effectively recovered when the automobile decelerates, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile deceleration inertial kinetic energy recovery system and method. Background technique [0002] We know that the engine of the car and the original car generator are connected by a belt. As long as the generator runs, the generator rotor will also rotate. The original car generator not only charges the original car battery when the car is running, but also provides Other on-board electrical appliances provide power. Due to the existence of the generator voltage regulator, it will continuously adjust the excitation current of the generator according to the change of the engine speed and the demand of the on-board electrical appliances to ensure a fixed output range of the generator. To ensure the power demand of the vehicle, the voltage regulator will increase the excitation current when the power of the on-board electrical appliances is increased, and the output po...

[0003] We also know that when the car is decelerating, there are actually two braking methods at play, one is the traditional braking system, and the other is the drag of the engine due to the inertial kinetic energy of the car, and the resistance generated by the engine on the car. That is to say, engine braking. Although the accelerator pedal is off and no additional fuel is supplied to the engine, the engine still has a high speed at this time. If the energy carried by such a high speed cannot be fully utilized , in today's increasingly tense energy environment, it is a pity
