Stellantis has built a prototype vehicle with new battery design that integrates the charging electronics and inverter. The Intelligent Battery Integrated System (IBIS) delivers a 10% energy efficiency improvement and a 15% power gain with the same battery size. Early results show a 15% reduction in charging time, along with a 10% reduction in energy consumption. It also reduces vehicle weight by 40Kg and frees up space for an additional 17 litres of cargo volume. By rethinking and simplifying the electric powertrain architecture, we are making it lighter, more efficient, and more cost-effective.
