Abstract: Battery management in a dual battery system may be achieved by a battery charging and discharging operation method and a system therefor. The method may, given an uphill section and a downhill section on a driving route to a destination in navigation information, calculate/determine an estimated charge amount by regenerative braking that may be acquired from the downhill section; determine whether to drive uphill only with a main high-voltage battery based on the estimated charge amount; and when driving uphill only with the main high-voltage battery, transfer, only to the main high-voltage battery, a charging path by the regenerative braking acquired from the downhill section, thereby reducing a system loss that may be caused by charge/discharge of a sub high-voltage battery.
