摘要： 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.

摘要： Disclosed is a cooling control method and system for a battery. The cooling control method includes measuring, by a controller, an exterior temperature of a vehicle and a temperature of a battery. When the exterior temperature of the vehicle exceeds a first temperature, the method includes setting, by the controller, a cooling reference temperature based on the temperature of the battery and the exterior temperature. Furthermore, the method includes cooling, by the controller, the battery by adjusting the intensity of a cooling fan based on the set cooling reference temperature to prevent the temperature of the battery upon termination of cooling from exceeding a second temperature.
