摘要：A system and method for controlling charging a battery of a hybrid vehicle are provided that charge the battery using a hybrid starter generator during limiting motor power for high temperature protection of the driving motor. Accordingly, a frequency of a driving motor reaching a power limitation due to high temperature protection is minimized while a driving time and frequency of a driving motor is reduced, by charging the battery by driving the hybrid starter generator (HSG) when a temperature of the driving motor reaches a predetermined level or greater due to a frequent driving of the driving motor while driving the hybrid vehicle.

主权项：1. A method for controlling charging of a vehicle battery, comprising: monitoring, by a controller, a temperature of a driving motor while a vehicle is driven; when the temperature of the driving motor is equal to or greater than “reference temperature for high temperature protection—α”, determining, by the controller, a current driving mode of the vehicle; when a current driving mode is hybrid electric vehicle (HEV) mode, charging, by the controller, the battery by driving a hybrid starter generator connected to a crank shaft of an engine; and when the current driving mode is an electric vehicle (EV) mode, charging, by the controller, the battery by driving the hybrid starter generator by starting the engine.
