Embodiment 1

[0035] This case discloses a split-type six-phase motor control method integrating AC charging, the main control module is respectively connected to the control terminals of the inverter unit module, the pre-charging module, the motor control switch and the AC control switch , to control its opening and closing;

[0036] Wherein, when the system is in the drive mode, the inverter unit module outputs electric energy to the motor drive circuit, and when the motor control switch is in a closed state, the AC control switch is turned off;

[0037] Conversely, when the system is in the charging mode, the external AC power supply inputs electric energy to the current conversion module through the AC charging socket, the AC control switch is in the closed state, and the motor control switch is turned off.

[0038] In this case, the power input end of each single motor in the six-phase motor is equipped with multiple motor inductors, and the motor is connected to multiple inverter unit...

Embodiment 2

[0041] Specifically, the main control unit module ( figure 2 (not shown) are respectively connected to the low-voltage signal output terminals of the AC charging socket 205 to receive the low-voltage signal in the charging socket. The main control unit module judges the working mode according to the received low-voltage signal or the signal of the vehicle controller.

[0042] For example, when the charging gun of an electric vehicle is connected to the AC charging socket, the low-voltage signal of the charging gun will activate the low-voltage control power supply on the main control unit module. After the main control unit module is powered on, it will switch the working mode of the system to the charging mode .

[0043] Afterwards, the main control unit module detects that the charging gun is connected to the system, and conducts information interaction with the charging pile through the PWM signal in the charging gun to confirm the power supply capability of the charging ...

Abstract

The invention discloses a split type six-phase motor control system integrated with alternating current charging. The system comprises a main control module, a driving module, a direct current module,a pre-charging module, an inversion unit module, a split type six-phase motor and a PFC inductance module connected to an alternating current socket. An alternating current charging port and a splittype six-phase motor port of the inversion unit module drive alternating current to input voltage signals to control a six-phase motor, and the inversion unit module is electrically connected with thealternating current socket through the PFC inductance module. According to the control method disclosed by the invention, a quick charging method of the alternating-current charging is adopted, and quick electric quantity input of the six-phase motor is realized through shunting and converging control of the inversion unit, so that the purpose of quick charging of the electric automobile is achieved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and more specifically, the invention relates to a split six-phase motor control system integrated with AC charging and a method thereof. Background technique [0002] With the development of modern science and technology, the increasingly serious environmental problems have gradually attracted people's attention, and how to better protect the environment while developing science and technology is particularly important. Green and environmentally friendly new energy vehicles have become the main focus of the future development of the automotive industry. At present, my country has comprehensively promoted the strategic development of new energy vehicles. The electric motor has replaced the traditional fuel engine as the core device of the automobile drive system. Discrete devices are used to control the motor in parallel, but how to solve the stability and charging of the device in the actual applic...
