Electric automobile and operating method thereof

Abstract

The invention discloses an electric automobile and an operating method thereof, relates to a technically improved electric automobile capable of saving the energy and increasing the braking efficiency, and provides an electric automobile and an operating method thereof, and the electric automobile can reduce the kinetic energy during vehicle brake so as to improve the vehicle braking efficiency, and can improve the comprehensive safety performance and energy-saving performance of vehicles. The electric automobile comprises a chassis, a brake pedal, a storage battery, a driving motor, a gearbox, a driving wheel, a driving shaft and a front bumper and also comprises a stored energy assistance device, wherein the stored energy assistance device comprises an energy accumulator, an inflating device, a charging device and a controller; the energy accumulator comprises a shell and an airbag; the airbag is arranged in the shell; the shell is fixedly connected to the inner surface of the front bumper; and an air inlet, an air outlet and a safety air valve port are formed in the airbag. The airbag is arranged in a non-sealed rigid shell to form the energy accumulator, and even if the airbag is burst, the phenomenon that people are injured under the limitation of the shell is avoided.

Description

technical field [0001] The invention relates to an electric vehicle and a working method thereof, in particular to a technical improvement for saving energy and improving braking performance of the electric vehicle. Background technique [0002] On August 28, 2009, the brake pedal incident of a certain brand of car, the problem existed in the design defect of the pedal pad, which caused the pad to get stuck on the accelerator, resulting in continuous operation of the accelerator, the car could not brake, resulting in a serious accident. The crash prompted the marque to issue its largest-ever recall, affecting 3.8 million vehicles in several model years dating back to 2004. [0003] The existence of this problem is that when the car is braking, the engine will continue to provide power to the gearbox and even the wheels, so that the braking force generated by the brakes is offset by the power generated by the car engine; when the car's engine speed is low, the transmitted...

AI Technical Summary

Problems solved by technology

[0002] On August 28, 2009, the brake pedal incident of a certain brand of car, the problem existed in the design defect of the pedal pad, which caused the pad to get stuck on the gas pedal, causing the gas pedal to continue to work, and the car could not brake, resulting in a serious car accident

[0003] The existence of this problem is that when the car is braking, the engine will continue to provide power to the gearbox and even the wheels, so that the braking force generated by the brakes is offset by the power generated by the car engine; when the car's engine speed is low, the transmitted power It is also relatively low, and the braking force of the brake can overcome the power of the engine and the inertia of the car to produce a braking effect; when the engine speed of the car is high, the transmission power is relatively high, and the inertia of the vehicle is also large. On the premise of overcoming the driving inertia of the car, it is also necessary to overcome the working power of the engine, so that it is difficult to guarantee the braking effect.
