Abstract: An apparatus for estimating a battery state of charge includes a computer that determines a lifespan of a battery by creating test conditions for the battery by reflecting predetermined driving information of a vehicle and then performing the test conditions; and a tester that performs charging according to predetermined charging conditions and discharging according to predetermined discharging conditions on the battery in accordance with the test conditions.

Abstract: An optimization method of a power control logic for entering into an idle stop & go (ISG) mode comprises steps of: monitoring a state of charge (SOC) of a battery to detect a parasitic current of the battery by a battery sensor of a vehicle; transmitting a parasitic current flag to an engine control unit (ECU) when the battery sensor detects the parasitic current; and determining whether a device using standby power of the battery is installed and increasing a voltage of the battery via additional power control when it is determined that the device is installed.

Abstract: A battery casing assembly for a vehicle includes a battery housing accommodating a battery therein; at least one cover having a size corresponding to a side surface of the battery housing so as to cover the side surface; and at least one guide formed along one or more edges of the battery housing to allow the cover to be fitted therein. With the structure, the battery casing assembly can prevent the heat emitted from the engine of the vehicle being transferred to the battery.

Abstract: Disclosed is a dark current cutoff system and method for a vehicle junction. In particular, a controller is configured to monitor signal input through a CAN communication module to determine when other modules in the vehicle are in a sleep mode, cut off battery power to a load device by turning off a switching element when the controller determines that the other modules in the vehicle are in sleep mode, and forcibly maintains an off state of the switching element for a set period time after the power has been cut, regardless of signal input through the CAN communication module.
