BATTERY CHARGE SUPPORT SYSTEM FOR REDUCING ENERGY LOSS

According to an aspect, a battery system for controlling a charging current includes a temperature sensor configured to measure a temperature of a first battery, a state-of-charge (SoC) calculation engine configured to calculate an SoC value of the first battery, and a charge current controller configured to determine an adjusted current according to a charge profile based on the temperature and the SoC value, where the charge current controller is configured to transmit current data that indicates the adjusted current to a device.
