Description
The present invention relates to a kind of controller for electric vehicle, be applicable to that battery-driven car when drag and descending slip, can be converted to electric energy with mechanical inertia, be the battery charging of battery-driven car.
Electrical Bicycle is a kind of zero pollution, low noise, safe, energy-conservation, the environmental protection vehicle of low fault have vast potential for future development at home and abroad, still, problems such as the biggest obstacle of puzzlement Electrical Bicycle industrialization is that the storage battery specific energy is low, and operating range is short.At present, be subjected to the restriction of engineering factor and material science, it is unpractical increasing substantially the storage battery specific energy by battery manufacturer fully.Electrical Bicycle does not all possess the energy back charge function that mechanical inertia can be changed into electric energy both at home and abroad, therefore, when Electrical Bicycle drag and downhill running, with the loss in vain of its mechanical kinetic energy, after the power consumption for the treatment of battery stores is used certain value, can only be by the external charge device to battery charge.
The purpose of this invention is to provide a kind of controller for electric vehicle, by the energy back charging control circuit, effectively utilized the rechargeable characteristic of storage battery, the mechanical inertia of Electrical Bicycle when drag and the descending can be converted to electric energy, in time the battery pack to battery-driven car charges, thereby improved the energy effective utilization rate, increased the continual mileage of battery-driven car.
In order to achieve the above object, the present invention adopts following technical measures: utilize the rechargeable characteristic of storage battery, when Electrical Bicycle drag and downhill running, mechanical inertia can be converted to electric energy, the anti-storage battery that is charged to, be an effective way that increases its specific energy, designed controller for electric vehicle.

When electric vehicle and bicycle drag or downhill running, block the storage battery power supply loop, charge circuit is provided, utilize pump to rise principle, make the counter potential of armature induction be higher than accumulator voltage, thereby form charging current, reaching can braking deceleration, again can feedback electric energy, to the purpose of battery charge, and then prolonged the continual mileage of battery-driven car.
The present invention compared with prior art has the following advantages and effect:
Mechanical kinetic energy when having made full use of braking of Electrical Bicycle frequently braking and downhill running is automatically converted to electric energy, in good time to battery charge, reaching can braking deceleration, again can feedback electric energy, to battery charging, improved the energy effective utilization rate, increased running distance of eletric vehicles, energy back during the descending brake increases electric weight 10-20%, and circuit structure is simple, detect by the Electrical Bicycle real-world operation, draw following data:

Fig. 1 is a kind of controller for electric vehicle electrical block diagram.
Below in conjunction with accompanying drawing the present invention is described in further detail.
According to Fig. 1 as can be known, 1 pin of controller IC 1 and 2 pin respectively with power switch pipe BG1, the G of BG2 is extremely continuous, controller IC 1 and resistance R 1, the upper end of R2 links to each other, resistance R 1, R2 lower end ground connection, resistance R 1, the main effect of R2 is in order to reduce VDMOS power switch pipe BG1, the input impedance of BG2, prevent to disturb, the D end of power switch pipe BG1 links to each other with the negative pole of sustained diode 1, link to each other with the positive pole of storage battery E simultaneously, the S end of power switch pipe BG1 links to each other with the D end of power switch pipe BG2, simultaneously with the negative pole of sustained diode 2, the left end of the positive pole of sustained diode 1 and reactor L1 links to each other, the S end of power switch pipe BG2 links to each other with the positive pole of sustained diode 2, link to each other with the negative pole of storage battery E simultaneously, also link to each other with the motor M right-hand member, the left end of motor M links to each other with the right-hand member of reactor L1, connects the loop thereby constituted semibridge system.When the battery-driven car cruising, 1 human hair combing waste of controller IC 1 goes out Continuity signal, make power switch pipe BG1 conducting, 2 human hair combing wastes of controller IC 1 go out cut-off signals, and power switch pipe BG2 turn-offs, the positive pole of storage battery E is powered to motor by D end, S end and the reactor L1 of power switch pipe BG1, it is rotatablely moved, and its current return is ABCDEA, when drag or descending, the control of power switch pipe BG1 and the controlled device IC1 of power switch pipe BG2 conducting sequential was divided into for three steps:
Sequential (one): power switch pipe BG1, BG2 turn-off simultaneously, and the energy that is stored in machine winding LM and reactor L1 forms counter potential, consumes by the DFCD loop.
Sequential (two): when counter potential was reduced to zero, controller IC 1 sent signal, power switch pipe BG2 conducting, power switch pipe BG1 turn-offs, simultaneously, because the mechanical inertia of battery-driven car, motor continues equidirectional rotation, and electrical motor becomes electrical generator, forms electric current by the CFDC loop.According to Kirchhoff's law, can draw following equation:
iR+E+Ldi/dt＝0 7-1
i＝-E/R+(I
2+E/R)
e -RT/L 7-2
E=K
eN
2In the 7-3 formula: E is the motor powered gesture, N
2Be motor speed, I
2Loop current for sequential (two) beginning.
Sequential (three): as power switch pipe BG2 after conducting a period of time, controller IC 1 sends signal again, make its shutoff, because being stored in the energy of machine winding LM and reactor L1 can not suddenly disappear, the automatic pump liter becomes counter potential to battery charging, its charge circuit is DCBAED, at this moment, to the electric energy of battery charge is:
W＝S
o ToffEidt
=E[(U
i-E)/R+ (I
On-(Ui-E)/R
e -R/L] therefore reached mechanical energy changes electric energy into to dt, automatic pump rises electrically-charged purpose, and RM is the DC machine equivalent resistance, and LM is the DC machine equivalent inductance.
