Description
Technical field
The present invention provides a kind of range extender of electric vehicle starting-generating switching control method, belongs to Control of Electric Vehicles technical field.
Background technology
Pure electric automobile has high efficiency, low noise, the advantages such as zero-emission, there is incomparable advantage in environmental protection and energy-saving square mask, its application and the universal inexorable trend having become auto industry sustainable development, but pure electric automobile continual mileage is limited, before not arriving at, if the electric energy of battery exhausts, electric automobile cannot advance, at this moment battery is badly in need of electric energy supplement, a kind of by high efficiency, the engine of the low emission generating set distance increasing unit integrated with starter-generator, can quickly give battery electric energy supplement, solve the too short problem of pure electric automobile continual mileage, therefore a kind of control method that range extender of electric vehicle can be made normally to work is invented necessary.
Content of the invention
It is an object of the invention to provide a kind of when storage battery charge state is less than 30%, start engine to run, after engine is properly functioning, starter-generator is converted to generator operation, the quick range extender of electric vehicle starting-generating switching control method giving battery electric energy supplement, control method stable, safe and reliable, its technology contents is:
Range extender of electric vehicle starting-generating switching control method, governor circuit is coordinated control starting circuit and starting-generating change-over circuit, is made starter-generator work, it is characterised in that: the duty of starter-generator is divided into starting state and generating state；
Starting state, when governor circuit obtains the state-of-charge SOC of battery less than 30%, close starting-generating change-over circuit, mu balanced circuit is protected, the rotor-position signal of starter-generator detected according to signal transducer, starting circuit is sent to after calculating the pulse signal needed for starter-generator, drive pulse signal is carried out power amplification and is input to inverter circuit by starting circuit, inverter circuit control current switching is simultaneously converted to three-phase alternating current the direct current of battery and flows to starter-generator, so that starter-generator work, starter-generator drives engine to run；
Generating state, after engine is properly functioning, governor circuit stops sending pulse drive signal to starting circuit, close starting circuit, starting circuit and inverter circuit are protected, send pulse signal to starting-generating change-over circuit simultaneously, starting-generating change-over circuit control starter-generator is converted to generator operation, starting-generating change-over circuit sends control signal to mu balanced circuit again, make the electric energy that starter-generator exports after mu balanced circuit voltage stabilizing and rectification, flow to battery and load, when governor circuit detects that battery is fully charged, governor circuit sends control signal, close engine.
The present invention compared with prior art, when storage battery charge state is less than 30%, starts engine and runs, and after engine is properly functioning, starter-generator is converted to generator operation, quick to battery electric energy supplement, increases electric automobile continual mileage.
