Abstract

Disclosed herein is a vehicle battery charging control system, which is capable of increasing efficiency of power delivered to an electric device and a low-voltage battery to improve fuel efficiency,by connecting a low-voltage DC-DC converter (LDC) to an AC power source instead of a high-voltage battery upon charging a low-voltage battery of a vehicle to prevent power delivery efficiency of an on-board battery charger (OBC) from being reduced.

Description

technical field [0001] The present invention relates to a vehicle battery charging control system, and more particularly, to a vehicle battery charging control system capable of charging a low voltage battery of a vehicle by connecting a low voltage DC-DC converter (LDC) to an AC power source. Instead of the high-voltage battery to prevent the reduction in power delivery efficiency of the on-board battery charger (OBC), to improve the efficiency of power delivered to electrical equipment and low-voltage batteries, thereby improving fuel efficiency. Background technique [0002] Eco-friendly vehicles include hybrid vehicles, plug-in hybrid vehicles, electric vehicles, fuel vehicles, and the like. Each of the plug-in hybrid vehicle and the electric vehicle is charged by a user using a home power source, and has an on-board battery charger (OBC) installed therein. [0003] When the plug-in hybrid vehicle or the electric vehicle is running, the inverter is located between the h...
