Overview

• IBIS embeds inverter and charger functions inside the pack so the battery supplies AC directly to the drive motors, removing the traditional power electronics module and on‑board AC charger.
• Stellantis reports up to a 10% efficiency gain on the WLTC cycle, a power increase to 172 kW from 150 kW, and roughly 15% faster AC charging in early testing.
• The company says the architecture cuts vehicle mass by about 40 kg and frees up to 17 liters of space while simplifying the under‑hood layout.
• Module‑level control with 48V outputs is designed to ease servicing and enable flexibility in cell chemistries, according to Stellantis and Saft.
• Road testing follows a stationary demonstrator running since mid‑2022, with Phase 2 supported by France 2030 and a potential production rollout targeted by the end of the decade.
