The energy regenerating of existing pure electric vehicle increases journey system to be implemented substantially under two states: inertia kinetic energy during brake and descending kinetic energy, stop at electricity, machine stops in combined switch and utilize electricity to stop switch by reversible for drive motor one-tenth electrical generator, recuperated energy dynamically charges to battery, and this cover technical scheme is ripe and use on vehicle.Because this energy regenerating depends on condition of road surface and driving technique and custom, increase Cheng Zuoyong and there is uncertainty and limitation, increase journey limited efficiency.
The present embodiment is on the basis of prior art thinking and scheme, and the energy dynamics obtained by changing operation scheme in global extent reclaims, and feeds back to power battery pack, to reach the object increasing journey.Its operation logic is: on follower, install hub generator, power battery pack exports energy to the wheel hub motor of drive wheel, moved ahead with certain acceleration/accel by the speed regulating device band motor vehicle of system controller, drive wheel and follower is made all to obtain kinetic energy, when the speed of a motor vehicle reaches the upper speed of a motor vehicle of setting, disconnect the power supply of power battery pack, vehicle must move ahead with deceleration/decel, the kinetic energy (wheel hub motor is reversible is electrical generator) of drive wheel and follower is converted to electric energy and recharges to power battery pack by increasing range controller output energy, when the speed of a motor vehicle is decelerated to the lower speed of a motor vehicle of setting, turn again by electrokinetic cell power make drive wheel accelerate advance, during to the upper speed of a motor vehicle, transfer to again and increase range controller work, power-off is decelerated to the lower speed of a motor vehicle, switching kinetics is battery-powered again, circulation like this, inertia kinetic energy in utilization between the speed of a motor vehicle and the lower speed of a motor vehicle is converted to electric energy and recharges to power battery pack, its computing formula is:

embodiment 4:
The present embodiment is on the basis of embodiment 3, add the recovery of the kinetic energy to drive wheel, its diagram of circuit as shown in Figure 5, adds in step s 13: the wheel hub motor on drive wheel is reversible is electrical generator, the kinetic energy of drive wheel is converted to electric energy, and is transferred to increasing range controller; Step S14 is further: increase range controller and the electric energy that hub generator and wheel hub motor transmission come is exported to power battery pack, is its charging.The inertia kinetic energy of drive wheel also can be able to be recycled like this, recovering effect is more effective, and increase Cheng Xiaoguo more stable, the time that continues is longer.
embodiment 5:
The present embodiment utilizes hub generator that the kinetic energy of follower is converted to electric energy, and be transferred to increasing range controller, and as shown in Figure 4, it comprises the following steps its diagram of circuit:
S51: in pure electric vehicle ride, the kinetic energy of follower is converted to electric energy by hub generator, and is transferred to increasing range controller;
S52: increasing range controller and utilize hub generator to transmit next electric energy for exporting to power battery pack again after himself power supply and/or cumlative energy, is power battery pack charging.
Pure electric vehicle unloading phase, i.e. acceleration phase, utilizes hub generator that the kinetic energy of follower is converted to electric energy, and is transferred to increasing range controller, when energy comparison hour, utilizes those energy to power for increasing range controller; When energy accumulation is to time a certain amount of, increase range controller and excess energy is exported to power battery pack, for power battery pack is powered.When pure electric vehicle reaches the predetermined upper speed of a motor vehicle, energy reclaiming method is in the same manner as in Example 4.
Existing electric bicycle is all the energy with electrokinetic cell, run through control system drive motor, and motor is by directly combining the propulsion source as drive wheel together with (or connecting with wheel hub through shaft coupling) with wheel hub, drive wheel is connected with follower (one or more) by support, thus drive vehicle forward by drive wheel, its energy conversion relation is:
Electric energy (electrokinetic cell) → kinetic energy 1(drive wheel)+kinetic energy 2(follower)+power consumption.
Conveniently thoughtcast, according to conservation of energy theorem, as one with the qualified car load dispatched from the factory, its energy consumption relation is determined, so the energy conservation in energy conversion relation, energy regenerating can not be had, so it is generally acknowledged and to ride while feedback energy is impossible to electrokinetic cell in ride.
But be through research to find, kinetic energy 2(follower) can be decomposed again, that is:
Kinetic energy 2(follower) rotational that mates with drive wheel of=kinetic energy 3() the implicit excess energy of+kinetic energy 4();
Kinetic energy 4 in above formula as energy regenerating, can convert back electrical energy to electrokinetic cell.Here implicit excess energy producing cause is: drive wheel and follower disalignment, connected by machinery mount between them, and controller and inductor are mainly for drive wheel, so there is an induction sensitivity in follower, namely the friction drag increase caused because load increases (weight increase or with electrical generator as passive wheel belt output load) for follower has a response lag, utilization can be recovered for the energy of (not response) in threshold value, so-called implicit excess energy that Here it is, when this threshold is passed, the load effect of follower can synchronously cause electrokinetic cell energy to increase, be in conservation energy state, now can not recuperated energy.
The increasing Cheng Fangfa of the present embodiment takes full advantage of this part implicit excess energy of follower, converts it to electric energy by hub generator, powers for increasing range controller and/or exports to power battery pack again after cumlative energy, is power battery pack charging.Achieve the energy regenerating in full operational process and dynamically recharge, i.e. limit operation limit charging, the implicit excess energy of follower and inertia kinetic energy are all recycled, accumulative increasing Cheng Xiaoguo is more obvious, and it is less that the average velociity of battery-driven car can be made to change.
Pure electric vehicle unloading phase, i.e. acceleration phase, also utilize hub generator that the kinetic energy of follower is converted to electric energy, and be transferred to increasing range controller, when energy comparison hour, the kinetic energy only reclaiming drive wheel is that power battery pack is powered, and the electric energy that the kinetic energy of follower converts to is only used for powering for increasing range controller and/or exporting to power battery pack again after cumlative energy, is power battery pack charging.Specific implementation process is: changed into by the step S13 in embodiment 4: the kinetic energy of follower is converted to electric energy by the hub generator on follower, and is transferred to increasing range controller, powers for increasing range controller; And wheel hub motor on drive wheel reversible be electrical generator, the kinetic energy of drive wheel is converted to electric energy, and is transferred to increasing range controller; Correspondingly, step S14 changes into: increase range controller and the electric energy that wheel hub motor transmission comes is exported to power battery pack, is power battery pack charging.When the energy accumulation of follower is to time a certain amount of, the kinetic energy of the kinetic energy and follower that simultaneously can reclaim drive wheel is power battery pack charging, now identical with embodiment 4.
embodiment 6:
The present embodiment is the increasing Cheng Fangfa of the increasing journey system for embodiment 3, and as shown in Figure 7, it comprises the following steps its diagram of circuit:
S91: power battery pack opens power supply, for the wheel hub motor on drive wheel is powered, drives drive wheel to rotate, drives pure electric vehicle to move ahead with certain acceleration/accel;
