Description
Technical field
The utility model relates to the improvement technology of battery-driven car, relates in particular to the improvement of two-wheeled, three-wheeled electric vehicle power system.
Background technology
Energy-conserving and environment-protective are themes of the world today, so battery-driven car arises at the historic moment.Battery-driven car is supplied power to electrical motor by vehicle-borne storage battery, and it is low, pollution-free to have energy consumption, has obtained great popularization and use.The electronic two-wheeled of selling in the market, three-wheel vehicle use chargeable batteries such as plumbic acid, ni-mh, lithium ion as power supply, but receive the restriction of capacity of cell, and travelled distance is limited.Although people also change point at research and development battery charging plant or storage battery; But the user is when using battery-driven car; Be difficult to avoid appearing at that the electric energy of storage battery exhausts in the road, the generation of charge condition in time, can use the user and bring very burden this moment.If battery discharge is dark excessively, can influence the service life of battery greatly.If the employing large-capacity battery can increase very big cost again, be unfavorable for promoting.
Summary of the invention
Limited in one's ability to the electric power storage of prior electric car battery, the problem that can not go on a long journey, the utility model provides a kind of hybrid power that can continue a journey, solves the not enough problem of long journey storage battery electric energy.
In order to solve the problems of the technologies described above; The utility model provides a kind of mini electric vehicle power system; Comprise the storage battery, electric machine controller and the drive motor that are installed on the vehicle body, the power end of said storage battery is connected with the input end of said electric machine controller, and the mouth of said electric machine controller is connected with the input end of said drive motor; It is characterized in that; Compact internal combustion engine and electrical generator also are installed on vehicle body, and the bent axle of said compact internal combustion engine is connected with the rotor of said electrical generator, and said electrical generator is electrically connected with the input end of charge controller; The mouth of this charge controller is connected with the charge power supply end of storage battery, and the mouth of said charge controller also is connected with the input end of electric machine controller.
The control end of said charge controller is connected with said compact internal combustion engine.
The mouth of said electric machine controller also is connected with the power input of said electrical generator.
The good effect of the utility model is:
Through the mode of operation of charge controller coordination storage battery and compact internal combustion engine, the preferential storage battery power supply that adopts when the battery-driven car cruising of this hybrid power; When the storage battery electric energy is not enough, start compact internal combustion engine, compact internal combustion engine drives magneto alternator work generating; The magneto alternator electricity can charge to storage battery and is drive motor power supply through charge controller; Realize that converting electric energy into by fuel consumption realizes continuation of the journey, it is limited that this effectively solves the battery-operated motor cycle batteries to store energy, the problem that should not go at a distance; Can make Vehicular accumulator cell when electric weight is not enough, also can continue a journey.
Adopt generator powered when the storage battery electric energy is not enough simultaneously, avoided battery overdischarge, overdraw to use, in the service life of having improved storage battery greatly, also reduce the requirement of battery-driven car the storage battery power capacity.
The electric energy that charge controller detects storage battery (generally all is the voltage that detects storage battery to a certain degree of depth; Be that voltage reaches a certain numerical value); The control output end output control signal of charge controller makes compact internal combustion engine quit work, and can reuse storage battery and go this moment.
Description of drawings
The principle of work scheme drawing of Fig. 1 the utility model charge condition;
Fig. 2 the utility model starts the principle of work scheme drawing of compact internal combustion engine state.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done further explain.
As depicted in figs. 1 and 2, a kind of mini electric vehicle power system comprises the storage battery, electric machine controller and the drive motor that are installed on the vehicle body; The power end of storage battery is connected with the input end of electric machine controller; The mouth of electric machine controller is connected with the input end of drive motor, and compact internal combustion engine and electrical generator also are installed on vehicle body, and electrical generator is that three-phase is many to utmost point magneto alternator; The bent axle of compact internal combustion engine is connected with the rotating shaft of the rotor of electrical generator; Electrical generator is electrically connected with the input end of charge controller, and the mouth of this charge controller is connected with the charge power supply end of storage battery, and the mouth of charge controller also is connected with the input end of electric machine controller.Wherein the control end of charge controller is connected with compact internal combustion engine.The mouth of electric machine controller also is connected with the power input of electrical generator.
In the time of use, the battery-driven car of this hybrid power preferentially adopts storage battery power supply.When the storage battery electric energy is not enough, starter-generator, and then by electrical generator startup compact internal combustion engine; Compact internal combustion engine drives permagnetic synchronous motor work generating; The electric energy that permagnetic synchronous motor sends charges to storage battery through charge controller and is the drive motor power supply, is battery charge while realize continuing a journey, thereby realizes that converting electric energy into by fuel consumption realizes continuation of the journey; It is limited that this effectively solves the battery-operated motor cycle batteries to store energy; The problem that should not go at a distance makes Vehicular accumulator cell when electric weight is not enough, and battery-driven car also can be continued a journey.When battery charge arrived certain voltage, the control output end of charge controller output control signal was shut down compact internal combustion engine, and can reuse storage battery and go this moment.
This shows that the utility model passes through the mode of operation that charge controller is coordinated storage battery and compact internal combustion engine; Both can utilize the storage battery electric energy; Can utilize the fuel oil energy to be converted into electric energy again at the storage battery electric energy after a little while and realize continuation of the journey, simultaneously can also be to battery charge.Because fuel oil can be easy to add to, and the fuel oil energy metric density is higher, the fuel oil energy converts the continuation of the journey that therefore electric energy can realize the utility model battery-driven car to.Adopt generator powered when the storage battery electric energy is not enough simultaneously, avoided battery overdischarge, overdraw to use, in the service life of having improved storage battery greatly, also reduce the requirement of battery-driven car the storage battery power capacity.
The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
