A battery pack is disclosed. In one aspect, the battery pack includes a chargeable battery and a battery management system (BMS) configured to charge the battery in a plurality of charging periods each including a constant current supply period and a constant voltage supply period. The battery pack also includes a resistance estimator configured to estimate the resistance of the battery. The BMS is further configured to change a charging period of the battery from a constant voltage supply period of an ith charging period to a constant current supply period of an (i+1)th charging period based on the resistance of the battery, and wherein i is a natural number.

A lighting system for a vehicle is provided. The lighting system includes a sensor module, a control mode, a shutter glass, and a headlamp module. The sensor module senses light entering from outside of the vehicle to generate a sensing signal. The control module generates shutter and lighting operation signals based on the sensing signal. The shutter glass is opened and closed according to the shutter operation signal. The headlamp module has a light source unit that alternately emits a first light having a first luminance and a second light having a second luminance according to the lighting operation signal. The control module controls the shutter and lighting operation signals to enable the light source unit to alternately emit the first and second lights in synchronization with the opening and closing operations of the shutter glass.
