Abstract: A system for charging a battery is provided. The system includes a high voltage battery that supplies electrical energy necessary to assist in a motor during acceleration of a vehicle and stores electrical energy generated by a motor regeneration during declaration of the vehicle or occurrence of a margin output of an engine. An on board charger receive AC power from a power supply which is supplied from the outside and supplies power for charging the high voltage battery. A battery management system transmits and receives charging and discharging information regarding the high voltage battery to and from the power supply through the on board charger using controller area network (CAN) communication.

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.

Abstract: An apparatus and method are provided for controlling a high voltage battery within vehicle. The apparatus monitors states of a first temperature sensor and a second temperature sensor mounted within a battery pack and calculates a replacement temperature that corresponds to the faulty temperature sensor using a temperature deviation within the battery pack for each ambient temperature of the battery when a faulty temperature sensor of the first temperature sensor and the second temperature sensor is detected. The replacement temperature is then used to operate the battery, and thus the stability of the battery control is improved even though the temperature sensor of the battery fails.
