Abstract

The invention discloses a vehicle-mounted charger with a drive motor function. A self-charge function is realized by using an electric vehicle drive motor. A complete charge controller can be formed by using the electric vehicle drive motor as well as the traditional structure and components of the controller without changing the inside structure.

Description

The onboard charger of band drive motors function

Affiliated field

The invention belongs to a kind of charger, especially a kind of onboard charger with the drive motors function.

Technical background

The known charge function needs to be born by independent charger (station), then needs to set up numerous charging stations for extensive development electric automobile, and this not only needs extensive fund, brings great inconvenience also for the charging of electric automobile.

Summary of the invention

The present invention utilizes driving motor for electric automobile to realize self-charge function.Utilize existing structure of driving motor for electric automobile and controller itself and device, simultaneously can constitute a complete charge controller not changing internal structure.

The present invention solves the technical scheme that its technical problem takes: by alternating current 220V ACThe supply socket power supply behind rectifying and wave-filtering, forms 310V DCDirect voltage, electric current is by motor coil B-A (equaling an inductance), and via controller inverter bridge B descends brachium pontis BT-switch modulation mutually, and when the BT-pipe turn-offed, the electric current in the inductance passed through to go up mutually the N+ end of the fly-wheel diode of BT+ pipe to battery; When the conducting of BT-pipe, the electric current in the inductance has formed one-period by the N-end that BT-manages battery.Duty ratio by PWM modulation BT-pipe can be adjusted charging current and voltage, utilize the charging procedure of the ferric phosphate lithium cell that former CPU includes then, battery is carried out constant current-constant voltage-trickle program control, treat to stop automatically after battery is full of electricity, finished charging process.

Usefulness of the present invention is:

1, needn't set up charging station separately, utilize civil power can realize vehicle-mounted charge.

2, be applicable to BS series permanent-magnet brushless DC electric machine and other serial driving motor for electric automobile.

Description of drawings

Fig. 1 is the onboard charger circuit diagram.

Among Fig. 1,1, rectifier, 2, filter capacitor, 3, controller inverter bridge B, 4, the PWM modulator, 5, descend brachium pontis BT-mutually, 6, go up brachium pontis BT+ pipe mutually, 7, motor coil B-A, 8, driving motor for electric automobile, 9, battery pack.

Specific implementation method

By alternating current 220V ACThe supply socket power supply behind rectifier (1) and filter capacitor (2) rectifying and wave-filtering, forms 310V DCDirect voltage, electric current is by the motor coil B-A (7) (equaling an inductance) in the driving motor for electric automobile (8), via controller inverter bridge B (3) descends brachium pontis BT-pipe (5) switch modulation mutually, because of the electric current in the inductance can not suddenly change, when descending brachium pontis BT-pipe (5) to turn-off mutually, electric current in the inductance arrives the N+ end of battery pack (9) by the fly-wheel diode of going up brachium pontis BT+ pipe (6) mutually, when descending (5) conducting of brachium pontis BT-pipe mutually, electric current in the inductance has formed one-period by descending the N-end of brachium pontis BT-pipe (5) to battery mutually.Duty ratio by brachium pontis BT-pipe (5) under PWM modulator (4) chopping phase can be adjusted charging current and voltage, utilize the charging procedure of the ferric phosphate lithium cell that former CPU includes then, battery is carried out constant current-constant voltage-trickle program control, treat to stop automatically after battery pack (9) is full of electricity, finished charging process.

Claims (1)

1. onboard charger with the drive motors function is characterized in that:
By alternating current 220V ACThe supply socket power supply behind rectifier and filter capacitor rectifying and wave-filtering, forms 310V DCDirect voltage, electric current is by the motor coil B-A (equaling an inductance) in the driving motor for electric automobile, via controller inverter bridge B descends brachium pontis BT-pipe switch modulation mutually, because of the electric current in the inductance can not suddenly change, when descending brachium pontis BT-pipe to turn-off mutually, the electric current in the inductance is held by the N+ that the fly-wheel diode of going up brachium pontis BT+ pipe mutually arrives battery pack, when descending the conducting of brachium pontis BT-pipe mutually, electric current in the inductance is managed the N-end of battery by descending brachium pontis BT-mutually, has formed one-period.
