The present invention relates to a battery diagnosis system and method, and disclosed is a battery diagnosis system including a receiving unit that receives information on a high voltage battery and charge state information of the high voltage battery of a vehicle being charged; a control unit that controls a current of the high voltage battery; a measurement unit that measures a voltage change amount of the high voltage battery in which the current is controlled; and a determination unit that determines the battery having the voltage change amount of an abnormal battery among the voltage change amounts of the battery measured in the measurement unit.

Battery diagnosis system and method

A system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor is disclosed. The system for managing a vehicle battery as disclosed includes a controller that receives a voltage of each of a plurality of battery cells in a vehicle battery, a temperature of the vehicle battery, and an insulation resistance of the vehicle battery, determines a reference value based on a deviation between voltages of the plurality of battery cells and the temperature of the vehicle battery, and determines whether the vehicle battery is abnormal by comparing the determined reference value with the insulation resistance.

System and method for managing vehicle battery

A battery cooling control method and a battery cooling control apparatus for an environmental vehicle equipped with a battery air cooling system are provided. The battery cooling control method includes collecting information for driving a cooling fan, performing data analysis based on the collected information, and performing battery cooling control based on a result of the data analysis, wherein the information includes vehicle sensor and actuator information, external environment information, and user information.

Battery cooling control method and apparatus for environmental vehicle

A system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor is disclosed. The system for managing a vehicle battery as disclosed includes a controller that measures a voltage of each of a plurality of battery cells in a vehicle battery when a voltage applied to the vehicle battery is constant, and determines whether the plurality of battery cells is abnormal based on a deviation between the measured voltages of the plurality of battery cells.

Disclosed is a system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor. The system for managing the vehicle battery as disclosed includes a controller that measures a polarization voltage of each of a plurality of battery cells in a vehicle battery after charging of the vehicle battery is terminated, and determines whether each of the plurality of battery cells is abnormal based on the measured polarization voltage.

System and method for diagnosing abnormality of vehicle battery

A system for managing the temperature of a battery, may include a battery configured to store electrical energy; a temperature-increase heater configured to convert the electrical energy stored in the battery into thermal energy to increase the temperature of the battery; a temperature-increase heater relay configured to connect or disconnect an electrical energy path provided from the battery to the temperature-increase heater; a thermal fuse configured to disconnect the electrical energy path when the temperature of the battery is equal to or higher than a predetermined reference temperature; and a controller configured to induce disconnection of the thermal fuse by increasing the temperature of the battery to the reference temperature or higher using the thermal energy converted by the temperature-increase heater, when the temperature-increase heater relay is fused.

System and method for managing battery temperature

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.
