Reach optimum state, it is ensured that vehicle security, the design requirement of power performance.
The enterprises for participating in developing all kinds of electric cars most at present, to motor used in automobile, automatically controlled, battery parameter
Selection on, typically by under the predetermined driving status of automobile, calculate and drive at a constant speed torque, the acceleration moment of resistance, ramp row
Sail the moment of resistance, the sum of moment of wind resistance and required max. speed, maximum continual mileage determine the power of motor, revolving speed,
The parameters such as peak torque, battery voltage, gross energy kilowatt hour (KW.h), are then carried out ordering each component by parameter.
Above-mentioned design calculates, and for conventional vehicle, or it is feasible for being included in the example vehicle of design study course, but for still
It is in the electric car of budding period, there are many determinations of parameter, and not say on existing teaching material does not have, even many authority scientific research department
Door and well-known scholar, all not mature design considerations.Therefore according to the above method simple designs come out electric car, often with
There is a big difference for design anticipation, and this gap must complete just have conclusion, but this when vehicle is installed into walking along the street examination
When many components determine that attachment, which manufactures several aspects and has, have been fixed, if adjustment or change will be paid from arrangement installation, position
The energy to get half the result with twice the effort out.
Summary of the invention
The purpose of the present invention is to provide a kind of experimental facility of power system of distance-increasing electric vehicle and methods, by increasing journey
The effect of formula power source control system makes extended-range power source, motor, torquemeter, generator overall work a kind of best
State, to obtain peak efficiency.
Technical solution of the present invention: experimental facility of power system of distance-increasing electric vehicle of the present invention will be selected
Extended-range power source, motor, torquemeter, generator, tunable load, power meter are installed in order；It is characterized in that, increasing
Formula power source, makes motor drive generator by torquemeter, and the electrical power of generator output becomes thermal energy by tunable load
It consumes；Tunable load consumes the size of power, directly proportional to the torque of motor reel output, defeated with extended-range power source
Power out is directly proportional.
Experimental method:
1) start extended-range power source, so that motor is driven generator by torquemeter, the electrical power of generator output is by adjustable
Load becomes thermal energy consumption, and is shown on power meter；
2) necessary torque value and the speed of service under following operating status that provide are calculated according to electric car design and can
Continue mileage travelled:
Straight road surface is set in drive at a constant speed as Mf；Having resistance when wind is Mw；The gradient resistance that climbing is is Mi；Add
Acceleration resistance when fast is Mj；
By adjusting the size of tunable load, torquemeter is set to stablize the value for showing above-mentioned Mf, Mw, Mi, Mj, at this time function
Rate table shows the performance number of motor output, which includes revolving speed, torque, voltage, electric current value parameter.
3) if the extended-range power source of motor can satisfy tetra- kinds of torque value difference of above-mentioned Mf, Mw, Mi, Mj
Occur or sets requirement any several while when occurring, then above-mentioned motor and extended-range power product-derived can be attached to choosing
On fixed vehicle, it is just centainly able to satisfy power performance requirement of the design calculation to the vehicle, otherwise it is dynamic to readjust extended-range
Power source or the parameter of electric machine repeat above-mentioned experiment, until satisfaction.
Beneficial effects of the present invention: the experimental facility of power system of distance-increasing electric vehicle and method tune through the invention
Whole experiment can make extended-range power source, motor, torquemeter, generator overall work in a kind of optimum state, obtain highest
Efficiency；Simultaneously before being packed into vehicle, selected motor, automatically controlled, battery are first carried out into performance matching test, design to be achieved
It moves and is attached on vehicle again after it is required that, reduce component change bring and do over again.
Detailed description of the invention
