A device for predicting a life expectancy of a fuse for a battery of an electric vehicle may include a sensor configured to generate and output current information about current flowing in the fuse, a processor, and a memory connected to the processor and configured to store a preset lookup table, the memory storing program instructions which are executable by the processor to generate fuse-life expectancy information corresponding to the fuse based on the lookup table and time corresponding to an excess when the current information exceeds a preset threshold value.

Fuse life expectancy prediction device for electric vehicle battery and prediction method thereof

Disclosed is a cooling system for a battery of a vehicle and a method for cooling the battery. A heat absorption member is attached to a terminal of battery cell of the battery for absorbing heat. A controller of the vehicle computes heat generation based on the driver's input about the vehicle's destination, controls the battery to limit its current output after temperature.

Vehicular battery cooling system and method for controlling the same

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 battery management system (BMS) may include a battery, a relay configured to electrically connect and disconnect the battery for supplying a voltage (an electric power) to an electric load to and from the electric load, the electric load configured to receive the voltage (the electric power) from the battery, to compare the received voltage (the electric power) with a reference value and to output a wakeup signal according to the compared result, when the relay is electrically connected, and a controller configured to wake up by the wakeup signal, to monitor a state of the battery and to control a state of the relay. It is possible to prevent overdischarge and overcharge of the battery by monitoring the battery through the electric load in a state in which a vehicle is turned off and switching the BSM to a wakeup state only if necessary.

Battery management system and method of controlling the same

A battery system includes a battery module; a cooling channel disposed adjacent to the battery module; a ground wire configured to electrically connect the cooling channel and a vehicle body; and a leakage current blocking device configured to interrupt an electrical connection of the cooling channel and the vehicle body when a leakage current occurs in the battery module.

Water cooled battery system with improved safety with respect to AC voltage insulation vulnerability

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.
