Description
Technical field
The utility model belongs to field of automobile.
Background technology
At present, development oil-electric vehicle and battery-driven car have become the new trend of auto trade, but the drive motor generating voltage is very low under the low moving velocity of electronlmobil, at this moment electrical generator generating characteristics are low-voltage and high-currents, feedback energy can not be recharged in this case battery pack and realize that energy reclaims.Therefore generally all this part energy dissipation has been fallen.
Summary of the invention
The purpose of this utility model is: a kind of electronlmobil low speed energy regenerative recovery control device is provided, and it can generate electricity the driving engine that hangs down moving velocity to charge to battery-driven car.
The technical solution of the utility model is: the cable of energy regenerative power generating system connects the input end of rectifier bridge, and rectification bridge output end connects the input end of resonance step-up, and the mouth of resonance step-up connects the positive and negative electrode of rechargeable battery.Brake pedal is connected start-up circuit plate input end with the Das Gaspedal input signal cable, the start-up circuit mouth connects recovery resonance step-up control circuit.
The beneficial effects of the utility model are: the low speed energy reclaims, and according to different demands, organic efficiency is greater than 70%.Auxiliary electrical drag function is provided; The identification of chaufeur driving intention, according to different driving habits and the speed of a motor vehicle, intelligent starting energy take-back model.Adopt power supply resonance step-up control technology, the electric energy of large current low voltage is converted to the energy realization energy recovery of large voltage low current.Control loop adopts overvoltage protection, and the overcurrent protection design is safe.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram;
Fig. 2 is cell pressure and energy regenerative voltage pattern;
Fig. 3 is that energy regenerative reclaims map of current after the resonant transformation;
Fig. 4 is pulse generation and IGBT driving circuit figure;
Fig. 5 is current feedback and voltage feedback circuit figure;
Fig. 6 reclaims degree of depth given circuit figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 2, Vb is cell pressure, and Vk is brake process electrical generator generating voltage, and Ik is the waste of heat electric current of motor, and through after the conversion process, Ic is charging current.
As shown in Figure 1, new-energy automobile is in brake process, and the kinetic energy of car load is converted into electric energy by the anti-electric generator that drags, because the speed of a motor vehicle is lower, at this time generating voltage also is lower than the voltage of electrokinetic cell, therefore can not realize recharging of electric energy.Energy regenerative generating is alternating current, enters the resonance major loop through overcommutation is laggard, and the electric energy of large current low voltage is changed high-tension electric energy, realizes that the energy regenerative of low speed reclaims.Present recoverable entry condition and finished by other system, start-up system is according to the driving intention of chaufeur, and according to the action relationships of Das Gaspedal and brake pedal, whether the startup that the decision energy reclaims.Sliding with braking is two kinds of different mode of operations, the entry condition that brake pedal reclaims as energy, the driving handling of raising new-energy automobile.
