Abstract
The utility model relates to a novel power system of an electric vehicle. The structure of the power system is as follows: wheel motors are respectively arranged at two ends of a drive shaft, a first battery pack is electrically connected with the two wheel motors through a controller, a generator is connected with the drive shaft through a transmission mechanism, a second battery pack, a charger and a charge regulator are further arranged in the power system, wherein the charger is respectively electrically connected with the first battery pack and the second battery pack through the charge regulator, the second battery pack is electrically connected with the controller, and the generator is electrically connected with the charger through the charge regulator. The two battery packs in the power system work by turns and charge by turns, thereby recycling a large amount of dissipated energy for driving the vehicle to drive and further improving the battery life of the electric vehicle.
Description
Technical field
The utility model relates to a kind of automobile dynamic system, specifically a kind of novel electric vehicle power system.
Background technology
For solving the environmental pollution that automobile quantity is increased sharply and caused, the research of new type power system vehicles such as clean fuel automobile, electronlmobil, hybrid vehicle is more and more deep, and new type power system vehicle operation more and more widely.Present used Electric Vehicle power system is at the two ends of axle drive shaft wheel electrical machine to be housed respectively, and battery pack is electrically connected with two wheel electrical machines by controller, and electrical generator connects axle drive shaft by transmission device.The use of this electrical generator is for providing the storage battery of electric power that charging power is provided to small-sized current consumers such as car light, locks.But the bigger defective that existing electronlmobil exists is exactly that flying power is lower, have to install increasing storage battery additional in battery pack for this reason, to improve capacitance of storage and continuation of the journey mileage.In a electronlmobil that China produces, the storage battery in the battery pack even be added to 100 more than, its travelled distance can reach about 300 kilometers.
The utility model content
The purpose of this utility model just provides a kind of novel electric vehicle power system, so that the flying power of electronlmobil is greatly improved.
The utility model is achieved in that a kind of novel electric vehicle power system, wheel electrical machine is equipped with at two ends at axle drive shaft respectively, first battery pack is electrically connected with two wheel electrical machines by controller, electrical generator connects axle drive shaft by transmission device, in described power system, also be provided with second battery pack, charger and charging modulator, charger is electrically connected with first battery pack and second battery pack respectively by the charging modulator, second battery pack is electrically connected with controller, and electrical generator is electrically connected with charger by the charging modulator.
The quantity of the storage battery in first battery pack described in the utility model and described second battery pack is identical.
Design philosophy of the present utility model is divided into two the battery pack in the power system of electric automobile exactly, promptly is divided into two battery packs that work alone, and adds parts such as charger and charging modulator simultaneously in power system.When first battery pack provides for power system in the process that energy makes running car, utilize an electrical generator bigger than original power, cooperating charging modulator and charger is that second battery pack carries out synchronous charging operations, and, in this process, the frequent braking energy of electronlmobil also can overlap charge system by this and feed back to second battery pack to greatest extent, gives accumulation of energy.Like this, when the electric weight of first battery pack exhausts substantially, in second battery pack, just charged into cooresponding electric weight, and automatic conversion and control or the manual intervention conversion and control under the instrument indication by controller, just can make second battery pack change into the work battery pack, first battery pack then transfers to be connected with charging modulator and charger, the electric weight that electrical generator charges into when working to receive and to store second battery pack.Such two group storage battery group alternate turns work, alternate turns charging.Though change the trend that the electric weight that charged into behind the battery pack can taper off at every turn,, by this structure design of the present utility model, the energy that originally much dissipates is recovered utilizes and drive running car.Through experimental test, be a battery pack with 50 storage batterys, two battery packs are possessed under the condition of 100 storage batterys, and the travelled distance of car type electronlmobil can reach more than 500 kilometers, and flying power obviously improves.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is to be separately installed with wheel electrical machine 2 at the two ends of the axle drive shaft 1 of electronlmobil, connects a transmission device 6 altogether on the dynamical axis of axle drive shaft 1 and electrical generator 5.Transmission device 6 can be belt gear or gear drive.In system, dispose two battery packs---first battery pack 3 and second battery pack 7.Two battery packs are electrically connected with controller 4 and charging modulator 9 respectively.Controller 4 is electrically connected with two wheel electrical machines 2 respectively, to realize that first battery pack 3 or second battery pack 7 are to the electric power supply of wheel electrical machine 2 and the regulating control of power supply voltage or supply current.9 of modulators of charging are electrically connected charger 8 and electrical generator 5 respectively, to realize the charging of electrical generator 5 by charging modulator 9 and 8 pairs first battery packs 3 of charger or second battery pack 7.Can select needs storage batteries group by charging modulator 9, and charging valtage or supply current are carried out regulating control.
Controller 4 and charging modulator 9 can adopt chip microcontroller intelligence to regulate and control.The quantity of the storage battery that disposes in two battery packs should be consistent.According to the difference of vehicle, the configurable 30-60 piece of the storage battery storage battery in every group.
