Wireless charging control apparatus and method for optimal charging by adjusting the inclination of the electric vehicle being charged
First Claim
1. A wireless charging control apparatus comprising:
- at least one horizontal detector configured for detecting an inclination of an electric vehicle (EV);
a suspension controller configured for controlling a plurality of suspensions mounted in the EV and disposed adjacent to wheels of the EV to adjust a height or the inclination of the EV; and
a controller measuring the inclination of the EV based on data collected from the at least one horizontal sensor, estimating an inclination of a reception pad based on the measured inclination of the EV, and controlling the suspension controller to adjust the inclination of the EV when the inclination of the reception pad is equal to or greater than a threshold value,wherein the controller is configured to compare a first unit charge amount measured before an adjustment of the inclination of the reception pad with a second unit charge amount measured after the adjustment of the inclination of the reception pad, and is configured to maintain an adjusted inclination of the reception pad when the second unit charge amount exceeds the first unit charge amount, and is configured to control the suspension controller to restore the inclination of the EV to a previous inclination before the adjustment of the inclination of the reception pad, when the second unit charge amount is equal to or less than the first unit charge amount.

Abstract
A wireless charging control apparatus may include at least one horizontal detector configured for detecting an inclination of an electric vehicle (EV); a suspension control device controlling a plurality of suspensions disposed near wheels of the EV to adjust a height or inclination of the EV; and a controller measuring the inclination of the EV based on data collected from the at least one horizontal sensor, estimating an inclination of a reception pad based on the measured inclination of the EV, and controlling the suspension control device to adjust the inclination of the EV when the inclination of the reception pad is equal to or greater than a predetermined threshold value.

10. A wireless charging control method comprising:
-
measuring, by a controller, an inclination of an electric vehicle (EV) using data collected through at least one horizontal sensor; estimating, by the controller, an inclination of a reception pad based on the measured inclination of the EV; and controlling, by the controller, at least one suspension mounted in the EV and disposed adjacent to wheels of the EV to adjust the inclination of the reception pad when the inclination of the reception pad is equal to or greater than a threshold value, wherein the controlling at least one suspension of the EV includes; determining a first unit charge amount, the first unit charge amount being an amount of energy charged during a first predetermined unit time before an adjustment of the inclination of the reception pad; determining a second unit charge amount, the second unit charge amount being an amount of energy charged during second redetermined unit time after the adjustment of the inclination of the reception pad; comparing the first unit charge amount with the second unit charge amount; and maintaining an adjusted inclination of the reception pad when the second unit charge amount exceeds the first unit charge amount and controlling the at least one suspension of the EV such that the inclination of the EV is restored to a previous inclination of the EV before the adjustment of the inclination of the reception pad. - View Dependent Claims (11, 12, 13, 14)
