摘要： A vehicle includes a vehicle battery; a vehicle sensor configured to detect a current, a voltage and a temperature of the vehicle battery; and an alternator configured to output a target voltage to the vehicle battery. A controller is configured to calculate state of charge (SOC) estimation based on the current, voltage and temperature of the vehicle battery, calculate an initial SOC based on a direct current internal resistance (DCIR) map and apply the initial SOC to the SOC estimation, when an open circuit voltage (OCV) is maintained in a predetermined range after engine-off, and adjust an available SOC range based on a difference between an actual battery charge current amount, to which the initial SOC is applied, and the calculated SOC estimation.

摘要： A strength-reinforcing metal sheet having repetitive concave and convex features is provided. Concave beads extend in repetitive quadrangular lattice features. A plurality of convex cells are defined between the beads, protrude above the beads, and have repetitive convex features. The upper portion of each of the cells has a pyramidal shape similar to a dome. The uppermost point thereof is formed at an eccentric point offset from the central point of the cell.
