  • Charge control method and system for vehicle
    Patent number: 9827870
    Abstract: A charge control method for a vehicle is provided which includes charging a first battery when the vehicle is in an IG ON operational state, maintaining the IG ON operational state and monitoring a second battery voltage. The charge control method further includes charging a second battery, calculating a vehicle speed when the vehicle is in an EV READY state and adjusting the EV READY state of the vehicle to the IG ON operational state when the calculated vehicle speed is less than a predetermined speed.
    Type: Grant

  • COOLING CONTROL METHOD AND SYSTEM FOR BATTERY
    Publication number: 20140174712
    Abstract: 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.
