CIRCUIT FOR CONTROLLING LOW POWER DC-DC CONVERTER OF HYBRID VEHICLE AND METHOD FOR CONTROLLING LOW POWER DC-DC CONVERTER
First Claim
1. A low power direct current-direct current (DC-DC) converter (LDC) control circuit, comprising:
- a detector configured to detect an output voltage of the LDC and characteristic factors in a vehicle;
a storage configured to receive the characteristic factors and to cumulatively store the characteristic factors; and
an LDC controller configured to initialize the characteristic factors cumulatively stored in the storage when a state of charge (SOC) of a vehicle battery is maintained to a preset value for a preset time while the LDC output voltage is maintained to be the same as in a refresh operation.

Abstract
A low power DC-DC converter (LDC) control circuit is provided and includes a detector, a storage, and an LDC. The detector detects an output voltage of the LDC and characteristic factors in a vehicle. The storage receives the characteristic factors and cumulatively stores the characteristic factors. The LDC controller initializes the characteristic factors cumulatively stored in the storage when a state of charge (SOC) of a battery of the vehicle is maintained to a preset value for a preset time while the LDC output voltage is maintained to be the same as in a refresh operation.

7. A low power direct current-direct current DC-DC converter (LDC) control method, comprising:
-
detecting, by a detector, an output voltage of the LDC and characteristic factors in a vehicle to determine whether to perform a refresh operation; receiving, by a storage, the characteristic factors and cumulatively storing the characteristic factors; determining, by an LDC controller, whether the LDC output voltage is maintained to be the same as in the refresh operation; determining, by the LDC controller, whether a time that state of charge (SOC) of a battery in the vehicle exceeds a preset value and exceeds a preset time; and initializing, by the LDC controller, the characteristic factors cumulatively stored in the storage. - View Dependent Claims (8, 9, 10, 11)
