Front wheels and back wheels of the electric automobile provided with a lithium battery pack are respectively provided with a front wheel motor and a back wheel motor, the front wheel motors and the back wheel motors are connected with a reversion switch by virtue of lines, two lines of the reversion switch are serially connected with two automobile controllers and then are respectively connected with a charging positive pole and a discharging positive pole of the lithium battery pack, the other two lines of the reversion switch are serially connected with two silicon rectifiers and then are respectively connected with the charging positive pole and the discharging positive pole of the lithium battery pack, and the lithium battery pack is provided with a shared discharging and charging negative pole. By adopting the device, when the electric energy is used during normal driving, only the back wheel motors are adopted to drive; when the automobile climbs up or accelerates, the front wheel motors and the back wheel motors can be simultaneously used; when the automobile climbs down or taxis, the reversion switch can change the charging method of the front wheel motors and the back wheel motors into the charging of the lithium battery pack, then the endurance capability of the electric automobile is enhanced, and the driving potentiality of the electric automobile is fully realized.
Description
Technical field
The present invention relates to a kind of electronlmobil, specifically a kind of electronlmobil charge and discharge device.
Background technology
Along with day by day exhausted with oil resources of gradually reducing of natural resources, exploitation and use electronlmobil have become the optimumitem of each auto vendor of the world, but in the developing of electronlmobil, a maximum difficult problem is exactly the use flying power after the charging of car lithium battery group, because this difficult problem perplexs automobile industry circle all the time, make it the exploitation of electronlmobil and use still to fail so far to be solved at all.
Summary of the invention
The object of the present invention is to provide a kind of electronlmobil charge and discharge device, the motor arranging before and after electronlmobil is adopted to electrode conversion, when electric discharge is used, can be exchanged into the charging of lithium cell group, can improve thus the flying power of electronlmobil.
The present invention includes lithium cell group, the concrete technical scheme adopting is as follows: the electronlmobil front and back wheel that lithium cell group is housed is installed respectively to front turbin generator and rear-wheel motor, motor in front and back wheel is connected with a change-over swith by circuit, after a side of change-over swith divides two circuits series winding to connect two automobile controllers, is connected respectively with two charge and discharge positive poles in vehicle-mounted lithium cell group; The opposite side of change-over swith is connected respectively with two charge and discharge positive poles in lithium cell group after dividing two circuit series windings to connect two silicon rectifiers; The connection mode forming thus can realize front and back wheel motor by change-over swith all can allow lithium cell group both can discharge and travel under switch condition, it can in the time sliding, be again the charging of lithium cell group, a shared charge and discharge negative pole can be set in lithium cell group, that is: the circuit of both sides all can share this negative pole.
The present invention passes through technique scheme, due to the front and back of electronlmobil are adopted respectively to front and back wheel electric machine structure, and connect with silicon rectifier series winding the mode being connected with lithium cell group through automobile controller by change-over swith, in addition in lithium cell group, arranging two can fill respectively, the positive pole of electric discharge connects, while normally travelling after charging electric vehicle, available rear-wheel motor drives and travels, go up a slope while maybe needing to accelerate to strengthen power, can open all motors of front and back wheel, and in the time of automobile slide or descending, can transfer front and back motor to charging modes through change-over swith is the charging of lithium cell group, make thus electronlmobil in the process of moving, can be according to road conditions and actual conversion adjustment reason of carrying out charge or discharge, can greatly improve the electric energy effect of lithium cell group, thereby improve the flying power of electronlmobil, efficiently solve the difficult problem that cannot improve flying power in present electronlmobil R&D process, have scientific and reasonable for structure, can fully improve and bring into play the effective utilization of lithium cell group and greatly improve the remarkable result of electronlmobil flying power.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing is structural representation of the present invention.
In figure: 1, lithium cell group, 2, front turbin generator, 3, rear-wheel motor, 4, change-over swith, 5, automobile controller, 6, silicon rectifier, 7, charge and discharge positive pole, 8, charge and discharge negative pole, 9, circuit.
The specific embodiment
Shown in accompanying drawing embodiment: the electronlmobil front and back wheel that lithium cell group 1 is housed is respectively arranged with front turbin generator 2 and rear-wheel motor 3, and front and back motor is connected with change-over swith 4 by circuit 9; Change-over swith 4 is connected respectively with two charge and discharge positive poles 7 in lithium cell group 1 after having two circuits, 9 series windings to connect two automobile controllers 5; Another two circuits 9 series windings connect after two silicon rectifiers 6 with 7 points, two charge and discharge positive poles in lithium cell group 1 and are connected and communicate; In lithium cell group 1, be provided with a shared negative pole 8 that discharges and recharges.
While implementing the technical program, the front and rear wheel of electronlmobil is all set to wheel motor and forms front turbin generator 2 and rear-wheel motor 3, change-over swith 4 and automobile controller 5 and silicon rectifier 6 are installed in the handled easily position in operator's compartment, and lithium cell group 1 selects electric energy lithium cell capable of circulation assembly to put use.Described automobile controller 5 can flow location electricity and become three plase alternating current value motor and use, and silicon rectifier 6 can be converted to motor alternating current after generating, and to become direct current (DC) be that lithium cell group 1 is charged.If it is when facilitating electronlmobil to need in the process of moving to charge that the technical program arranges two charge and discharge positive poles 7 in lithium cell group 1 simultaneously, carry out respectively with two positive poles, two charge and discharge positive poles 7 can be mutually general.
Implementing when this technology, also can several wind power generation plants to be set in the front side of automobile, in the time of electric automobile during traveling, jointly charge to lithium cell group with car generating electricity by front wheel machine, can better improve thus the flying power of electronlmobil.
