Abstract
The invention relates to an electric motor coach power control method: (1) when the coach is in a starting state, a generator set and a battery pack provide low current to make up the dropout voltage of a super capacitor according to the allocation principle; the super capacitor outputs high current to a driving system for driving a motor; (2) when a control system has an electric braking signal, braking energy starts to feedback, at the beginning, the super capacitor is used for bearing high load current to feed back and store the braking energy, and the generator set has no output power; when the feedback peak current is dropped out, the braking feedback energy charges the battery pack to carry out energy interaction mutually. In the electric motor coach power control method, the electric quantity of the purely electric motor coach can be utilized rationally, so as to drive longer distance with limit electric quantity.
Description
Technical field
The present invention relates to a kind of Poewr control method of electronlmobil.
Background technology
Cause the variation of weather along with the greenhouse gas emission that increases day by day, the application of pure electric coach extraordinarily is subjected to the attention and the approval of the whole society, but the restriction of applying or be subjected to the control of himself power of pure electric coach, there is generator set in the system, electrokinetic cell, three power cells of super capacitor, the necessary co-operative control of the power of three unit, the stack of three's power can guarantee the tractive performance of automobile, it is too fast to avoid peak current to cause voltage to rise again, damage total system, cause insulation breakdown, cause danger,, will make the popularization of pure electric coach encounter difficulties if do not solve the problem of the co-operative control of power.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed a kind of battery-driven car electric weight that can make and rationally utilized, and make can the travel electrobus control method of longer mileage of limited electric weight.
The present invention is achieved by the following technical solutions:
A kind of electric motor coach power control method:
(1) when car load is in starting state, be distribution principle according to the optimal discharge efficient and the maximum discharge current of electrokinetic cell, generator set and battery pack provide little electric current that the voltage that super capacitor falls is remedied; Super capacitor is exported big electric current and is given drive system, is used for drive motor, and the two carries out energetic interaction, satisfies the power requirement;
(2) when control system has the electric braking signal, braking energy feedback begins, initially bear big load current feedback and store braking energy by super capacitor, generator set no-output power, the moment of energy feedback battery pack hidden the impact of peak current effectively to battery pack, when the peak current of feedback had fallen, the feedback braking energy was given batteries charging again, and the two carries out energetic interaction.
(3) when car speed is in smooth running, provides power to the vehicle consumer by generator set and dynamic lithium battery, and can charge to electric capacity by generator set.
The present invention is by reasonably distributing the electric energy of controlling battery-driven car and using power, thereby make the electric energy of battery in the electrobus can access reasonable use, improved the travelled distance of electrobus, improved the organic efficiency of energy, improved the efficient of driving engine in the generator set, because the stack of three's power, increased the tractive performance of vehicle again, meet the demand of urban public transport to vehicle.
The specific embodiment
Electric motor coach power control method of the present invention:
(1) when car load is in starting state, be distribution principle according to the optimal discharge efficient and the maximum discharge current of electrokinetic cell, generator set and battery pack provide little electric current that the voltage that super capacitor falls is remedied; Super capacitor is exported big electric current and is given drive system, is used for drive motor, and the two carries out energetic interaction, satisfies the power requirement;
(2) when control system has the electric braking signal, braking energy feedback begins, initially bear big load current feedback and store braking energy by super capacitor, generator set no-output power, the moment of energy feedback battery pack hidden the impact of peak current effectively to battery pack, when the peak current of feedback had fallen, the feedback braking energy was given batteries charging again, and the two carries out energetic interaction.
