Abstract: A method and system for controlling charge and discharge of a battery are provided. The method includes detecting a battery temperature using a temperature sensor and determining, by a 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. The controller selects a lowest SOC from among at least one SOC to use a maximum discharging power equal to the determined first maximum discharging power value and resets the first maximum charging power value to a second maximum charging power value that corresponds to the selected lowest SOC. Further, the controller is configured to perform a charge and a discharge of the battery with the reset second maximum charging power value at the detected battery temperature.

Abstract: A system for charging a vehicle battery includes a relay configured to establish/interrupt electrical connection between the vehicle battery and a vehicle system supplied with power from the vehicle battery, and a controller. The controller is configured to monitor a voltage of the battery, control the relay to interrupt the electrical connection when a voltage of the battery is less than or equal to a first predetermined reference value, and control the relay to establish the electrical connection when a predetermined condition is satisfied while the relay is electrically disconnected. The controller controls the relay to be electrically connected to charge the battery through an external power source while the electrical connection is interrupted, and then control a connection state of the relay based on the voltage of the battery, a voltage and current of the relay at a side of the vehicle system, and whether a vehicle is started.
