Power following is used when vehicle power demand is greater than Pemin, vehicle power demand uses invariable power mould when being less than Pemin
Formula.
The energy control method of the range extended electric vehicle power system, the detailed process of the constant power mode
Are as follows: it according to the SOC threshold value of accumulator of electric car, determines the open and close of distance increasing unit, sets the upper limit value of battery SOC
SOCmax and lower limit value SOCmin, when SOC value of battery is greater than SOCmax, distance increasing unit is closed, when SOC value of battery is lower than SOCmin
When, distance increasing unit starting, when battery SOC is between SOCmax and SOCmin, distance increasing unit keeps the work shape of previous moment
State.
The energy control method of the range extended electric vehicle power system, the specific mistake of the Power following
Journey are as follows: when vehicle demand power is high or battery SOC value is relatively low, distance increasing unit can be opened, only when battery SOC is higher than on default
When limiting threshold values SOCmax and vehicle demand power and being less than Pemin, distance increasing unit is closed.
The energy control method of the range extended electric vehicle power system is in series with driving on the DC bus
Electric machine controller and driving motor.
The utility model has the advantages that

For driving motor for electric automobile power supply, electric car is made to realize the ability that continues for being up to several hundred kilometers.Stroke-increasing electric automobile vehicle
It carries battery weight and only needs 50% or so of pure electric automobile, the cost and weight of on-vehicle battery can be greatly reduced；Battery
Will not short of electricity and overdischarge, the service life extended.
2. distance increasing unit of the present invention uses starting/power generation integrated formula motor, the special motor for starting engine can be saved,
Reduce the volume and weight of distance increasing unit, save the cost improves functional reliability；Intelligent controller leads to according to the signal detected
Control algolithm realization is crossed to the intelligent control of distance increasing unit working condition.
3. distance increasing unit of the invention is installed in vehicle over long distances when driving for convenience of the portable free standing unit of disassembly
On, it is connected by mechanical and electric interfaces with vehicle dynamical system, when driving, the side for not installing distance increasing unit may be selected in short distance
Formula farthest mitigates complete vehicle quality.
4. the present invention is combined using invariable power and Power following, distance increasing unit and battery is made to work opposite
Efficient region, takes into account distance increasing unit discharge and life of storage battery problem is followed that is, when vehicle driving demand power is big using power
Control strategy avoids battery from being large current discharge；When vehicle driving demand power is small, according to SOC state at that time, closes and increase
Journey device improves system effectiveness, improves discharge.
