Claim Text:
1. A method of controlling charge and discharge of a battery for a vehicle, comprising: detecting, by a controller, a battery temperature using a temperature sensor; determining, by the controller, a state of charge (SOC) of the battery, a first maximum discharging power value, and a first maximum charging power value that correspond to the battery temperature; selecting, by the controller, a lowest SOC from among at least one SOC to use a maximum discharging power equal to the determined first maximum discharging power value; resetting, by the controller, the first maximum charging power value to a second maximum charging power value that corresponds to the selected lowest SOC and maintaining the first maximum discharging power value that corresponds to the selected lowest SOC; and performing, by the controller, a charge and a discharge of the battery with the reset second maximum charging power value at the detected battery temperature and the maintained first maximum discharging power value at the detected battery temperature.
