Abstract
An electrified vehicle may include: a main battery and an auxiliary battery; a motor system including a dual inverter connected to the main battery and driving a motor depending on a motor driving mode, and a transfer switch for switching between first and second driving modes included in the motor driving mode; and a charging switch connected between the motor system and the auxiliary battery, and configured to form a boost charging path connected from the auxiliary battery to the main battery through the motor system when the first driving mode switches to a charging mode while driving.
Claims20
An electrified vehicle comprising:
- a main battery and an auxiliary battery;
- a motor system comprising a dual inverter connected to the main battery and driving a motor depending on a motor driving mode, and a transfer switch for switching between first and second driving modes included in the motor driving mode;
- and
- a charging switch connected between the motor system and the auxiliary battery, and configured to form a boost charging path connected from the auxiliary battery to the main battery through the motor system in a charging mode while driving,
- wherein in the charging mode while driving, the boost charging path from the auxiliary battery to the main battery is formed through a neutral point of the motor formed in the first driving mode.
An electrified vehicle comprising:
- a main battery and an auxiliary battery;
- a motor system configured to drive a motor through an inverter connected to the main battery;
- and
- a controller configured to perform, when a charging mode while driving is performed, a preconfigured pulse width modulation control on the inverter to control a DC offset for a phase current of the motor such that the motor system boosts the voltage of the auxiliary battery to charge the main battery,
- wherein in the charging mode while driving, a boost charging path from the auxiliary battery to the main battery is formed through a neutral point of the motor.
A method of controlling an electrified vehicle, the method comprising:
- driving a motor through an inverter based on a voltage of a main battery in a motor system;
- and
- forming a boost charging path connected from an auxiliary battery to the main battery through the motor system when a charging mode while driving is performed in a state in which the motor is driven,
- wherein in the charging mode while driving, the boost charging path from the auxiliary battery to the main battery is formed through a neutral point of the motor.
