Abstract

The invention discloses a starting system for a range-extending type electric automobile. The starting system comprises a DC/DC, a control switch and a direct current/alternating current inverter. The control switch is in series connection between the DC/DC and the direct current/alternating current inverter. The starting system for the range-extending type electric automobile has the following beneficial effects that power supply is directly from output of a battery case of the electric automobile, a starter of a traditional automobile is not needed, and a lead-acid battery for starting an engine of the traditional automobile is not needed. In this way, the cost of the whole automobile is lowered, and reliability is improved.

Description

A kind of engine starting gear for stroke-increasing electric automobile
Technical field:
The invention belongs to new-energy automobile field, relate to a kind of engine starting gear.
Background technology:
The present whole world all suffers from environmental pollution, the threat that petroleum resources are exhausted, and internal-combustion engines vehicle is one of major reason causing this crisis, and internal-combustion engines vehicle not only consumes petroleum resource, but also gives off harmful substance. Coping with challenges, Ge great motor corporation of the world and all actively developing energy-conservation and new-energy automobile research about research institution, wherein the research contents of emphasis is exactly electric automobile. The development course of electric automobile is based on plug-in hybrid (PHEV) and extended-range. Plug-in hybrid-power automobile relies solely on battery just can exercise longer distance, it is necessary to time still can work as common hybrid vehicle.
Extended-range electric vehicle is very similar with plug-in hybrid-power automobile mode of operation, both can be individually entered energy to travel under electric-only mode by electrokinetic cell, and when electrokinetic cell capacity all turns, after the lower limit set, the energy continued needed for offer vehicle by another power source. Extended-range electric vehicle can avoid stopping for charging continually as far as possible. Plug-in hybrid-power automobile is to be evolved by hybrid vehicle, it inherits most of feature of hybrid vehicle, no matter extended-range electric vehicle is operated in electric-only mode or increases under journey pattern, its wheel is only independently driven by motor all the time, if and plug-in hybrid-power automobile is operated under hybrid mode, electromotor can participate in the ranks driving wheel together with motor (after power coupling).
Extended-range electric vehicle is because equipped with petrol engine, so needing to start device. If started by the trigger of orthodox car, it is desirable to have independent power supply (such as with lead-acid battery) and it needs to electromotor charges for it.
Summary of the invention:
It is an object of the invention to provide the startup system of a kind of extended-range automobile, this system cost is low, safety, reliable and non-maintaining.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions:
A kind of engine starting gear for stroke-increasing electric automobile, including DC/DC, controls switch, DC/AC inverter.
Control switch it is in series with between described DC/DC and DC/AC inverter.
The engine starting gear of the stroke-increasing electric automobile of the present invention has the advantage that
Power supply exports directly from the battery case of electric automobile;
The trigger of orthodox car does not need;
Orthodox car starts the lead-acid battery of electromotor and does not need.
This makes the cost of car load reduce, and adds reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the engine starting gear of stroke-increasing electric automobile;
In figure: 1, battery case positive pole; 2, battery case negative pole; 3, DC/DC; 4, the control relay of trigger; 5, DC/AC inverter; 6, electromotor; 7, the connection axle of electromotor and electromotor; 8, electromotor.
Detailed description of the invention
With reference to Fig. 1, the engine starting gear of a kind of stroke-increasing electric automobile, including DC/DC, control relay, DC/AC inverter, electromotor, the connection axle of electromotor and electromotor, electromotor.
Solution:
Utilizing the principle of reversibility of magneto alternator, when to electromotor input AC electricity, it can work in a motor mode. Therefore when controlling relay and closing, electromotor works under electric model, drives engine rotation. When engine speed reaches certain speed, its electric injection system is started working, and at this moment controls relay and disconnects, and electromotor will work under normal power generation mode, charge to battery system.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, without departing within the scope of technical solution of the present invention, when method and the technology contents of available the disclosure above make a little Equivalent embodiments changing or being modified to equivalent variations, in every case it is the content without departing from technical solution of the present invention, according to any simple modification that above example is made by the technical spirit of the present invention, equivalent variations and modification, still fall within the scope of technical solution of the present invention.
