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

A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

Fuse box for battery of vehicle

A battery pack structure of a vehicle, may include a cell module assembly formed by stacking a plurality of cell modules, end plates coupled to both side end portions of the cell module assembly, and support plates coupled to the top and the bottom of the cell module assembly and both side end portions of the end plates to bring the cell modules in contact with each other.

Battery pack structure with support plates

A vehicle battery case is provided. The battery case includes a lower panel and at least one transverse member that is disposed on the lower panel to increase transverse rigidity. Additionally, at least one longitudinal member is disposed on the lower panel to increase longitudinal rigidity, and a sidewall member is attached to an upper surface of the lower panel along a rim of the lower panel.

Vehicle battery case

A connector and a decking structure between a vehicle body and a battery including the same are provided. The connector includes a first connector assembly that has a downwardly protruding guide pin and a second connector assembly that is coupled to the first connector assembly in a lower portion of the first connector assembly and includes a guide aperture in which the guide pin is accommodated.

Connector and docking structure between vehicle body and battery comprising the same

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.

System and method for charging a vehicle battery by controlling a relay between the battery and a vehicle system

A battery management system for a vehicle is provided. The system is capable of preventing vehicle malfunction by preventing overcharge and over-discharge of a low-voltage battery by providing a controller that is configured to receive power transmitted from a first connection line and power transmitted from a second connection line. The battery management system includes a relay configured to electrically connect and disconnect power that is supplied from a battery to loads. The system also includes a controller configured to receive a first regular power transmitted through a connection line between the battery and the relay and a second regular power transmitted through a connection line between the relay and the loads. The controller is further configured to turn the relay on and off.

Battery management system for vehicle

A battery cooling system includes: a housing in which an inlet duct from which air is introduced and an outlet duct through which the air is discharged are mounted; a first battery mounted in the housing and disposed between the inlet duct and the outlet duct; and a low voltage battery disposed between the first battery and the inlet duct.

Battery cooling system

A female connector of a high voltage junction box includes a first case and a second case that are coupled to form a space for accommodation of electric wiring, a connector housing configured as a pipe at one side of the first case and having an internal opening portion that is closed via coupling with a holder formed in the second case, and a bus bar extending from the electric wiring, inserted into the connector housing, and fixed to the connector housing by the holder. A method for assembling the female connector includes holding electric wiring on a first case to insert a bus bar formed on the electric wiring into a connector housing formed on the first case for connection with external wiring; coupling the first case and the second case to fix the bus bar; and forming a space for accommodation of the electric wiring.

Female connector of high voltage junction box and method for assembling the same

A battery management method is provided which suitably includes measuring voltage, current and temperature of a battery, calculating the State of Charge (SOC) of the battery using the integration value of the measured current of the battery, and calibrating the calculated SOC of the battery. The voltage, current and temperature of the battery are measured by an Electronic control Unit (ECU).
