Abstract
An embodiment multi-input charging device includes a disconnector actuator system (DAS) controller configured to release an engagement of a DAS in response to receipt of a multi-charging input signal, a charging efficiency calculator configured to calculate a charging efficiency of a battery according to a rotor position of a rotor of a drive motor, a rotor controller configured to change the rotor position through a motor speed control until a particular rotor position having a highest charging efficiency is detected, and a charging controller configured to start multi-charging at the particular rotor position.
Claims20
A multi-input charging device, the device comprising:
- a disconnector actuator system (DAS) controller configured to release an engagement of a DAS in response to receipt of a multi-charging input signal;
- a charging efficiency calculator configured to calculate a charging efficiency of a battery according to a rotor position of a rotor of a drive motor;
- a rotor controller configured to change the rotor position through a motor speed control until a particular rotor position having a highest charging efficiency is detected;
- and
- a charging controller configured to start multi-charging at the particular rotor position.
A multi-input charging method, the method comprising:
- releasing an engagement of a disconnector actuator system (DAS) in response to receiving a multi-charging input signal;
- confirming a first rotor position of a rotor of a drive motor;
- calculating a first charging efficiency of a battery at the first rotor position through an initial charging current;
- changing the first rotor position to a second rotor position through a motor speed control;
- calculating a second charging efficiency of the battery at the second rotor position;
- fixing the rotor to a particular rotor position, wherein the particular rotor position is a rotor position having a highest charging efficiency;
- and
- starting multi-charging by re-engaging the DAS after fixing the rotor to the particular rotor position.
