The combustion engine current supply circuit includes the power generation assembly that a combustion engine and connects combustion engine, and the generating of internal-combustion engine drives power generation assembly so that power generation assembly produces an electric power, and is exported electric power by the power output end of power generation assembly.The super capacitor current supply circuit then includes at least one super capacitor, and its electric power of supplying is to export via the super capacitor current supply circuit.
The loop control switching circuit is connected in combustion engine current supply circuit and super capacitor current supply circuit, under the control of loop control switching circuit is switched, make combustion engine current supply circuit and motor form path and give motor by the power output end output power of power generation assembly, and make super capacitor current supply circuit and motor form path and give motor by the super capacitor output power, so electric power supply apparatus can be in response to different electricity needs, and then form path and supply power to motor with the motor of electric vehicle system at the same time or separately.In addition, the loop control switching circuit also includes a charge circuit, can make the electric power of the power output end output of power generation assembly be able to charge to super capacitor via charge circuit.
The present invention contrasts the effect of prior art:
Via the technology used in the present invention means, be by the instrument of super capacitor as store electrical energy, because the photoelectric transformation efficiency of super capacitor is than general storage battery height, so super capacitor provides good with the general storage battery of efficiency ratio of store electrical energy at short notice, that is super capacitor can be in the quite short time charge and discharge, and the energy storage process of super capacitor is compared based on the process of chemical reaction with traditional storage battery, without any the combination or the disconnection of chemical bond.So super capacitor have have extended cycle life, advantages such as high-energy-density, superpower fan-out capability and compliance with environmental protection requirements, can effectively improve known hybrid electric when starting, quicken, slowing down or climbing, because under the frequent highpowerpulse, and reduce life-span of its storage battery, and cause battery-driven car jiggly shortcoming in travelling.
In addition, because super capacitor has the advantage of lightweight, corpusculumization, the comparison traditional storage battery can effectively be improved its big weight and must expend the problem that macro-energy more just can make car drive.
Moreover, technological means via loop control switching circuit controlling combustion engine current supply circuit and super capacitor current supply circuit, can effectively control the voltage of the motor that exports battery-driven car to, promote stationarity and the traveling comfort of battery-driven car in travelling, increase the whole efficiency of electric vehicle system.And needed a large amount of electric energy when this technological means can effectively be improved hybrid electric because of car starting, acceleration or climbing, and cause combustion engine to improve rotating speed, make to produce more multicontaminated problem by fuel incomplete combustion in combustion engine.
