Steel has superior lightweight cost competitiveness (excellent physical properties in strength, formability, weldability and corrosion resistance with lower cost) compared to other alternative materials. With the opening of the new era of mass-production for electric vehicles (EVs), POSCO is a global leader in providing a broad range of advanced high strength steel (AHSS) solutions. Recently POSCO has developed the "POSCO Body Concept for Electric Vehicle (PBC-EV)," which achieved over 20% weight reduction by the use of AHSS grades (>64%). A total life cycle emission of PBC-EV is reduced by ~50% comparing to the benchmarking ICE vehicle. These are accomplished while meeting an extensive list of global safety requirements such as US FMVSS, IIHS and EuroNCAP. POSCO has also developed the concept of a steel-intensive lightweight, "POSCO Battery Pack for Electric Vehicle (PBP-EV)," which has an energy capacity of 60kWh and crash protection. The safety of a battery pack against vehicle collision is enhanced using Giga-strength steels comprising ~40% of total weight for reinforcements and brackets.
