Abstract

A power control apparatus for a vehicle battery that includes a relay configured to interrupt or connect electric power supplied from the battery to a vehicle; current sensors configured to detect a battery discharging current supplied to a load of the vehicle through the relay, and a battery charging current introduced from an alternator of the vehicle. In addition, the apparatus includes a controller configured to output a control signal to execute an on / off drive of the relay based on detection values of the current sensors to control the electric power supplied from the battery to the vehicle. The relay, the current sensors, and the controller are mounted to the battery, and the current sensor includes a high current sensor having a substantially large current measurement range and a low current sensor having a substantially small current measurement range.

Description

technical field [0001] The present invention relates to a power control device for a vehicle battery, and more particularly, to a power control device for a vehicle battery that can automatically interrupt battery power during overcurrent, vehicle collision, battery discharge due to dark current, or battery overcharge. Power control device. Background technique [0002] As is known in the art, a battery is mounted on a vehicle to supply power to a starter motor during vehicle start-up or to various electrical loads such as audio visual (AV) systems, lights, sensors and controllers. [0003] Such batteries may include 24V batteries depending on vehicle models in addition to 12V batteries, and with the recent increase in the number of electric loads in vehicles, 42V batteries are being applied. Such a vehicle battery is configured to supply electric power to a starter motor or an electric load in the vehicle through current discharge, and to store electric power for the alter...
