The battery management device may include a battery that provides energy to a drive motor that drives a vehicle, a battery system which is configured for measuring a temperature and an state of charge (SOC) value of the battery and is configured to control the temperature of the battery and a processor. The processor is configured to determine an estimated battery temperature and an estimated SOC value of the battery at each of at least one stopover on an expected driving route of the vehicle to reach a destination of the vehicle, determine an estimated charging time for charging the battery to a preset capacity at the stopovers based on the estimated battery temperature and the estimated SOC value, determine a stopover, as a recommended charging point, where the estimated charging time is minimum among the stopovers and provide a user with a guidance for the recommended charging point.

Battery management device and method therefor

A method for charging a battery at a low temperature in a battery system is provided. The system includes a charger that provides power for charging the battery and a temperature-increasing device that generates heat using the power provided from the charger to increase a temperature of the battery.

Method for charging battery at low temperature

A method of predicting time for charging a battery of an eco-friendly vehicle can include: measuring a temperature and a voltage of the battery using one or more sensors; comparing the measured temperature and voltage with pre-stored data values; identifying a charging step among a plurality of charging steps; calculating a charging current value and a cutoff voltage value according to the identified charging step; and calculating an expected charging time by adding a second time to the expected charging time when a first time is greater than the second time or by adding the first time to the expected charging time when the second time is greater than the first time.

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.

Apparatus and method for controlling a high voltage battery in vehicle

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.

System and method for charging battery

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.

The present invention provides a method for estimating a distance to empty (DTE) from the present amount of remaining fuel (the amount of remaining electricity) in an electric vehicle. In particular, the present invention provides a method for estimating a remaining travel distance of an electric vehicle, which can efficiently and accurately estimate a remaining travel distance by setting the relationship of a DTE with a state of charge (SOC) of a battery which changes in real time under various load conditions, in consideration of the present travel pattern, in addition to the SOC of a battery and accumulated fuel efficiency for the amount of remaining fuel of the electric vehicle.
