A kind of highway electricity generation system based on linear electric motors mainly comprises linear electric motors, energy storage device and is connected between the two charging circuit, also comprises the control circuit that energy storage device is discharged and recharged control.The stator of linear electric motors is embedded in the car lane breeze way, preferably at the center, track and occupy the width in track 2/3, is fixed on vehicle undercarriage as the magnet of its mover, and magnet is preferably electromagnet.Stator comprises stator core and is wrapped in stator coil in stator core, and stator coil is embedded under the road surface position of 3 to 5 centimetres, is parallel to the road surface and arranges.
The car lane breeze way comprises car lane descending highway section, turning of motor vehicle highway section and the car lane charge station highway section of entering the station.When being equiped with the motor vehicle process car lane breeze way of magnet, stator coil output pulse current.Charging circuit is used for the pulse current of stator coil output is converted to charging current, is the energy storage device charging with charging current.Energy storage device comprises a kind of in storage battery and super capacitor or both combinations.In the present embodiment, also comprise for the electric energy conversion that energy storage device is collected based on the highway electricity generation system of linear electric motors becoming the power frequency electricity to flow to the micro-grid system that power consumption equipment used or flowed to electrical network.
According to Lenz's law as can be known, when the stator coil of the motor vehicle of carry magnet and motor stator part does relative motion, can produce an electromagnetic resistance, this electromagnetic resistance stops the generation of relative motion, therefore produce and weaken motor vehicle traction and along the effect of the partical gravity on road surface, play a kind of non-contacting braking effect.Because this braking procedure is contactless mode, therefore the phenomenon of wheel lock up or motor vehicle drift can not appear, can not cause mechanical damage to motor vehicle yet, can reduce the driver to the useful life of the upkeep cost of motor vehicle and prolongation tire.Preferably, the length in descending highway section is more than or equal to 50 meters, and the angle of turn in turning highway section so, when utilizing the motor vehicle generating, is not prone to the situation that motor vehicle normally travels that affects, for example the situation of transition auxiliary braking more than or equal to 60 degree.

Thus, can find out, linear motor stator electric is embedded on highway, utilize built-in pulse charging circuit that the pulse current of motor vehicle through out-of-date generation charged to energy storage device, the auxiliary machine motor-car braking simultaneously of can generating electricity, the energy of recovery section loss.
Native system has adopted following strategy in order to maximize the energy that reclaims loss:
1, the inhomogeneous placement of stator core and stator coil
Along the travel direction of motor vehicle, in the descending highway section, the enter the station generating district in highway section of charge station, stator core and stator coil adopt first close rear thin disposing way.Because when stator coil was sensed the variation magnetic field of bringing from motor vehicle excitation electromagnet, by Lenz's law as can be known, stator coil can hinder the variation in magnetic field, namely hinders advancing of motor vehicle.Therefore, such disposing way can be so that motor vehicle can effectively slow down when just entering the generating district.Along with advancing of motor vehicle, stator coil is put and is become sparse, can be so that the unnecessary energy of motor vehicle is effectively utilized in generating is distinguished;
In the generating district of car lane angle of turn more than or equal to the turning highway section of 60 degree, the coil of curve inner side than the coil in the bend outside more crypto set a bit, can allow car deceleration faster, turn more steady;
If in steeper descending highway section, adopt comparatively intensive disposing way.Because in the process of descending, the unnecessary energy of motor vehicle also comprises the gravitational potential loss of energy, and the energy equivalence of this part is huge, must adopt the more disposing way of crypto set, could effectively guarantee the safety of travelling and the maximum using of energy.
2, height and the adjustable excitation electromagnet of electric current
Electromagnet is installed on a liftable support, and this liftable support is fixed on vehicle undercarriage.The controller of liftable support is connected with motor vehicle control system with on-vehicle battery.When motor vehicle enters the generating district, the driver can be by connecting the switch of electromagnet, allow the highway electricity generation system start working, controlling simultaneously liftable support descends, the electromagnet of originally pressing close to chassis is dropped to safe distance apart from ground, allow the air gap of motor diminish, improve generating efficiency, wherein electromagnet can be connected by different switches from vehicle battery with liftable support, realizes controlled and is controlled by motor vehicle control system.For example, the height that can descend by adjusting electromagnet, realize adjusting energy conversion efficiency, for example liftable support drops to minimum point immediately after startup, then progressively rise, allow the motor vehicle can be the poor conversion of sizable a part of kinetic energy to motor when just entering breeze way (generating district), the electromagnet that then slowly raises, the conversion that makes motor vehicle reduce energy when being about to roll the generating district away from keeps certain speed.Also can be arranged on when running into emergency (brake for example being detected is floored), realize rapid auxiliary braking in generating is distinguished by the big or small and height that descend of electric current in the adjustment electromagnet.Then, get up and be sent to corresponding micro-grid system and unify to process by the power storage that energy storage device sends highway, the electric energy that highway is sent in realization converts the power frequency electric energy to for the user directly, simultaneously charging station can also be installed on highway, for the new energy source machine motor-car provides charging device, required electric energy is from the electric energy by providing after little electrical network conversion.
Native system is by adopting micro-grid system, can realize that highway electricity generation system and electric power system be incorporated into the power networks, can be the peripheral electricity consumption facility normal power supply situation of guarantee when the generating peak period under additional electric energy sell electric power system by being incorporated into the power networks.Therefore build on highway radio frequency identification equipment is arranged, the energy of contribution in the time of recording each motor vehicle and process generating district thereof, as long as motor vehicle has been carried electric energy in the district that generates electricity for micro-grid system and will have been gone on record, mode by network, information is sent in the system of charge station, can encourages and promote this technical scheme by the high speed expense of reducing or remitting a part.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
