Abstract

The present invention relates to an apparatus and a method for estimating an SOC and, more particularly, to an apparatus and a method for estimating an SOC for estimating an initial SOC at the startupof a starting lighting ignition (SLI) battery provided in a vehicle. One aspect of the present invention has an advantage in that it is possible to accurately estimate an initial SOC of a vehicle starting battery that always uses a current regardless of whether a vehicle is in a driving mode or a parking mode.

Description

technical field [0001] This application claims priority from Korean Patent Application No. 10-2018-0114990 filed in Korea on September 27, 2018, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to an SOC estimating device and method, and more particularly, to an SOC estimating device and method for estimating an initial SOC at the time of SLI (Starting Lighting Ignition: Start Lighting Ignition) battery start of a vehicle. Background technique [0003] In recent years, the demand for portable electronic products such as notebook computers, video cameras, and portable phones has increased dramatically, and energy storage batteries, robots, and satellites have also been actively developed. Therefore, high-performance secondary batteries that allow repeated charging and discharging are being actively researched. [0004] Currently commercially available secondary batteries include nickel-cadmium batteries, nickel-metal hydrid...
