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.

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 vehicle and a method use an Idle Stop and Go (ISG) system. The vehicle includes: a battery; a battery sensor configured to measure a lowest voltage of the battery at a time of startup of the vehicle; a driving unit including an engine of the vehicle; and a controller. The controller is configured to: compare a first lowest voltage predicted using a current lowest voltage of the battery with a reference value to determine whether the lowest voltage of the battery has been changed; in response to determining the lowest voltage of the battery has been changed, calculate a difference between the current lowest voltage of the battery and an immediately previous lowest voltage of the battery; calculate an accumulated current between a current of the battery at the immediately previous time point and a current of the battery at the current time point; calculate a correction voltage for the accumulated current; predict a second lowest voltage using at least one of the difference between the current lowest voltage of the battery and the immediately previous lowest voltage of the battery or the correction voltage; compare the second lowest voltage with a second determination value; and control the driving unit to control entry into a stop of the ISG system according to a result of the comparison.
